The

+.Nm
+utility displays and modifies the Internet-to-Ethernet address translation
tables used by the address resolution protocol
.Pq Xr arp 4 .
With no flags, the program displays the current
using Internet dot notation.
.Pp
Available options:
-.Bl -tag -width Ds
+.Bl -tag -width indent
.It Fl a
-The program displays all of the current
+The program displays or deletes all of the current
.Tn ARP
entries.
.It Fl d
with the
.Fl d
flag.
+If the
+.Cm pub
+keyword is specified, only the
+.Dq published
+.Tn ARP
+entry
+for this host will be deleted.
+If the
+.Cm ifscope
+keyword is specified, the entry specific to the interface will be deleted.
+.Pp
+Alternatively, the
+.Fl d
+flag may be combined with the
+.Fl a
+flag to delete all entries.
+.It Fl i Ar interface
+Limit the operation scope to the
+.Tn ARP
+entries on
+.Ar interface .
+Applicable only to the following operations:
+display one, display all, delete all.
+.It Fl n
+Show network addresses as numbers (normally
+.Nm
+attempts to display addresses symbolically).
.It Fl s Ar hostname ether_addr
Create an
.Tn ARP
entry for the host called
.Ar hostname
-with the Ethernet address
+with the Ethernet address
.Ar ether_addr .
The Ethernet address is given as six hex bytes separated by colons.
The entry will be permanent unless the word
-.Ar temp
-is given in the command.
+.Cm temp
+is given in the command.
If the word
-.Ar pub
-is given, the entry will be "published"; i.e., this system will
+.Cm pub
+is given, the entry will be
+.Dq published ;
+i.e., this system will
act as an
.Tn ARP
server,
-responding to requests for
+responding to requests for
.Ar hostname
even though the host address is not its own.
-.It Fl f
-Causes the file
+In this case the
+.Ar ether_addr
+can be given as
+.Cm auto
+in which case the interfaces on this host will be examined,
+and if one of them is found to occupy the same subnet, its
+Ethernet address will be used.
+If the
+.Cm only
+keyword is also specified, this will create a
+.Dq "published (proxy only)"
+entry.
+This type of entry is created automatically if
+.Nm
+detects that a routing table entry for
+.Ar hostname
+already exists.
+.Pp
+If the
+.Cm reject
+keyword is specified the entry will be marked so that traffic to
+the host will be discarded and the sender will be notified the
+host is unreachable.
+The
+.Cm blackhole
+keyword is similar in that traffic is discarded but the sender is
+not notified.
+These can be used to block external traffic to a host without
+using a firewall.
+.Pp
+If the
+.Cm ifscope
+keyword is specified, the entry will set with an additional property that
+strictly associate the entry to the interface. This allows
+for the presence of mutiple entries with the same destination
+on different interfaces.
+.It Fl S Ar hostname ether_addr
+Is just like
+.Fl s
+except any existing
+.Tn ARP
+entry for this host will be deleted first.
+.It Fl f Ar filename
+Cause the file

-.Sh DESCRIPTION\r
-The\r
-.Nm\r
-utility uses the\r
-.Tn ICMP\r
-.No protocol Ap s mandatory\r
-.Tn ECHO_REQUEST\r
-datagram to elicit an\r
-.Tn ICMP ECHO_RESPONSE\r
-from a host or gateway.\r
-.Tn ECHO_REQUEST\r
-datagrams\r
-.Pq Dq pings\r
-have an IP and\r
-.Tn ICMP\r
-header, followed by a\r
-.Dq struct timeval\r
-and then an arbitrary number of\r
-.Dq pad\r
-bytes used to fill out the packet.\r
-The options are as follows:\r
-.Bl -tag -width indent\r
-.It Fl A\r
-Audible.\r
-Output a bell\r
-.Tn ( ASCII\r
-0x07)\r
-character when no packet is received before the next packet\r
-is transmitted.\r
-To cater for round-trip times that are longer than the interval\r
-between transmissions, further missing packets cause a bell only\r
-if the maximum number of unreceived packets has increased.\r
-.It Fl a\r
-Audible.\r
-Include a bell\r
-.Tn ( ASCII\r
-0x07)\r
-character in the output when any packet is received.\r
-This option is ignored\r
-if other format options are present.\r
-.It Fl c Ar count\r
-Stop after sending\r
-(and receiving)\r
-.Ar count\r
-.Tn ECHO_RESPONSE\r
-packets.\r
-If this option is not specified,\r
-.Nm\r
-will operate until interrupted.\r
-.It Fl D\r
-Set the Don't Fragment bit.\r
-.It Fl d\r
-Set the\r
-.Dv SO_DEBUG\r
-option on the socket being used.\r
-.It Fl f\r
-Flood ping.\r
-Outputs packets as fast as they come back or one hundred times per second,\r
-whichever is more.\r
-For every\r
-.Tn ECHO_REQUEST\r
-sent a period\r
-.Dq .\&\r
-is printed, while for every\r
-.Tn ECHO_REPLY\r
-received a backspace is printed.\r
-This provides a rapid display of how many packets are being dropped.\r
-Only the super-user may use this option.\r
-.Bf -emphasis\r
-This can be very hard on a network and should be used with caution.\r
-.Ef\r
-.It Fl I Ar iface\r
-Source multicast packets with the given interface address.\r
-This flag only applies if the ping destination is a multicast address.\r
-.It Fl i Ar wait\r
-Wait\r
-.Ar wait\r
-seconds\r
-.Em between sending each packet .\r
-The default is to wait for one second between each packet.\r
-The wait time may be fractional, but only the super-user may specify\r
-values less than 1 second.\r
-This option is incompatible with the\r
-.Fl f\r
-option.\r
-.It Fl L\r
-Suppress loopback of multicast packets.\r
-This flag only applies if the ping destination is a multicast address.\r
-.It Fl l Ar preload\r
-If\r
-.Ar preload\r
-is specified,\r
-.Nm\r
-sends that many packets as fast as possible before falling into its normal\r
-mode of behavior.\r
-Only the super-user may use this option.\r
-.It Fl M Cm mask | time\r
-Use\r
-.Dv ICMP_MASKREQ\r
-or\r
-.Dv ICMP_TSTAMP\r
-instead of\r
-.Dv ICMP_ECHO .\r
-For\r
-.Cm mask ,\r
-print the netmask of the remote machine.\r
-Set the\r
-.Va net.inet.icmp.maskrepl\r
-MIB variable to enable\r
-.Dv ICMP_MASKREPLY .\r
-For\r
-.Cm time ,\r
-print the origination, reception and transmission timestamps.\r
-.It Fl m Ar ttl\r
-Set the IP Time To Live for outgoing packets.\r
-If not specified, the kernel uses the value of the\r
-.Va net.inet.ip.ttl\r
-MIB variable.\r
-.It Fl n\r
-Numeric output only.\r
-No attempt will be made to lookup symbolic names for host addresses.\r
-.It Fl o\r
-Exit successfully after receiving one reply packet.\r
-.It Fl P Ar policy\r
-.Ar policy\r
-specifies IPsec policy for the ping session.\r
-For details please refer to\r
-.Xr ipsec 4\r
-and\r
-.Xr ipsec_set_policy 3 .\r
-.It Fl p Ar pattern\r
-You may specify up to 16\r
-.Dq pad\r
-bytes to fill out the packet you send.\r
-This is useful for diagnosing data-dependent problems in a network.\r
-For example,\r
-.Dq Li \-p ff\r
-will cause the sent packet to be filled with all\r
-ones.\r
-.It Fl Q\r
-Somewhat quiet output.\r
-.No Don Ap t\r
-display ICMP error messages that are in response to our query messages.\r
-Originally, the\r
-.Fl v\r
-flag was required to display such errors, but\r
-.Fl v\r
-displays all ICMP error messages.\r
-On a busy machine, this output can be overbearing.\r
-Without the\r
-.Fl Q\r
-flag,\r
-.Nm\r
-prints out any ICMP error messages caused by its own ECHO_REQUEST\r
-messages.\r
-.It Fl q\r
-Quiet output.\r
-Nothing is displayed except the summary lines at startup time and\r
-when finished.\r
-.It Fl R\r
-Record route.\r
-Includes the\r
-.Tn RECORD_ROUTE\r
-option in the\r
-.Tn ECHO_REQUEST\r
-packet and displays\r
-the route buffer on returned packets.\r
-Note that the IP header is only large enough for nine such routes;\r
-the\r
-.Xr traceroute 8\r
-command is usually better at determining the route packets take to a\r
-particular destination.\r
-If more routes come back than should, such as due to an illegal spoofed\r
-packet, ping will print the route list and then truncate it at the correct\r
-spot.\r
-Many hosts ignore or discard the\r
-.Tn RECORD_ROUTE\r
-option.\r
-.It Fl r\r
-Bypass the normal routing tables and send directly to a host on an attached\r
-network.\r
-If the host is not on a directly-attached network, an error is returned.\r
-This option can be used to ping a local host through an interface\r
-that has no route through it\r
-(e.g., after the interface was dropped by\r
-.Xr routed 8 ) .\r
-.It Fl S Ar src_addr\r
-Use the following IP address as the source address in outgoing packets.\r
-On hosts with more than one IP address, this option can be used to\r
-force the source address to be something other than the IP address\r
-of the interface the probe packet is sent on.\r
-If the IP address\r
-is not one of this machine's interface addresses, an error is\r
-returned and nothing is sent.\r
-.It Fl s Ar packetsize\r
-Specify the number of data bytes to be sent.\r
-The default is 56, which translates into 64\r
-.Tn ICMP\r
-data bytes when combined\r
-with the 8 bytes of\r
-.Tn ICMP\r
-header data.\r
-.It Fl T Ar ttl\r
-Set the IP Time To Live for multicasted packets.\r
-This flag only applies if the ping destination is a multicast address.\r
-.It Fl t Ar timeout\r
-Specify a timeout, in seconds, before ping exits regardless of how\r
-many packets have been received.\r
-.It Fl v\r
-Verbose output.\r
-.Tn ICMP\r
-packets other than\r
-.Tn ECHO_RESPONSE\r
-that are received are listed.\r
-.It Fl z Ar tos\r
-Use the specified type of service.\r
-.El\r
-.Pp\r
-When using\r
-.Nm\r
-for fault isolation, it should first be run on the local host, to verify\r
-that the local network interface is up and running.\r
-Then, hosts and gateways further and further away should be\r
-.Dq pinged .\r
-Round-trip times and packet loss statistics are computed.\r
-If duplicate packets are received, they are not included in the packet\r
-loss calculation, although the round trip time of these packets is used\r
-in calculating the round-trip time statistics.\r
-When the specified number of packets have been sent\r
-(and received)\r
-or if the program is terminated with a\r
-.Dv SIGINT ,\r
-a brief summary is displayed, showing the number of packets sent and\r
-received, and the minimum, mean, maximum, and standard deviation of\r
-the round-trip times.\r
-.Pp\r
-If\r
-.Nm\r
-receives a\r
-.Dv SIGINFO\r
-(see the\r
-.Cm status\r
-argument for\r

-When a\r

-is given, this indicated the size of this extra piece of data\r
-(the default is 56).\r
-Thus the amount of data received inside of an IP packet of type\r

-will always be 8 bytes more than the requested data space\r
-(the\r
-.Tn ICMP\r
-header).\r

-.Sh DUPLICATE AND DAMAGED PACKETS\r
-The\r
-.Nm\r
-utility will report duplicate and damaged packets.\r
-Duplicate packets should never occur when pinging a unicast address,\r
-and seem to be caused by\r
-inappropriate link-level retransmissions.\r
-Duplicates may occur in many situations and are rarely\r
-(if ever)\r
-a good sign, although the presence of low levels of duplicates may not\r
-always be cause for alarm.\r
-Duplicates are expected when pinging a broadcast or multicast address,\r
-since they are not really duplicates but replies from different hosts\r
-to the same request.\r
-.Pp\r
-Damaged packets are obviously serious cause for alarm and often\r
-indicate broken hardware somewhere in the\r
-.Nm\r
-packet's path (in the network or in the hosts).\r
-.Sh TRYING DIFFERENT DATA PATTERNS\r
-The\r
-(inter)network\r
-layer should never treat packets differently depending on the data\r
-contained in the data portion.\r
-Unfortunately, data-dependent problems have been known to sneak into\r
-networks and remain undetected for long periods of time.\r
-In many cases the particular pattern that will have problems is something\r
-that does not have sufficient\r
-.Dq transitions ,\r
-such as all ones or all zeros, or a pattern right at the edge, such as\r
-almost all zeros.\r
-It is not\r
-necessarily enough to specify a data pattern of all zeros (for example)\r
-on the command line because the pattern that is of interest is\r
-at the data link level, and the relationship between what you type and\r
-what the controllers transmit can be complicated.\r
-.Pp\r
-This means that if you have a data-dependent problem you will probably\r
-have to do a lot of testing to find it.\r
-If you are lucky, you may manage to find a file that either\r
-cannot\r
-be sent across your network or that takes much longer to transfer than\r
-other similar length files.\r
-You can then examine this file for repeated patterns that you can test\r
-using the\r
-.Fl p\r
-option of\r
-.Nm .\r
-.Sh TTL DETAILS\r
-The\r
-.Tn TTL\r
-value of an IP packet represents the maximum number of IP routers\r
-that the packet can go through before being thrown away.\r
-In current practice you can expect each router in the Internet to decrement\r
-the\r
-.Tn TTL\r
-field by exactly one.\r
-.Pp\r
-The\r
-.Tn TCP/IP\r
-specification recommends setting the\r
-.Tn TTL\r
-field for\r
-.Tn IP\r
-packets to 64, but many systems use smaller values\r
-.No ( Bx 4.3\r
-uses 30,\r
-.Bx 4.2\r
-used 15).\r
-.Pp\r
-The maximum possible value of this field is 255, and most\r
-.Ux\r
-systems set\r
-the\r
-.Tn TTL\r
-field of\r
-.Tn ICMP ECHO_REQUEST\r
-packets to 255.\r
-This is why you will find you can\r
-.Dq ping\r
-some hosts, but not reach them with\r
-.Xr telnet 1\r
-or\r
-.Xr ftp 1 .\r
-.Pp\r
-In normal operation\r

+.Sh DESCRIPTION
+The
+.Nm
+utility uses the
+.Tn ICMP
+.No protocol Ap s mandatory
+.Tn ECHO_REQUEST
+datagram to elicit an
+.Tn ICMP ECHO_RESPONSE
+from a host or gateway.
+.Tn ECHO_REQUEST
+datagrams
+.Pq Dq pings
+have an IP and
+.Tn ICMP
+header, followed by a
+.Dq struct timeval
+and then an arbitrary number of
+.Dq pad
+bytes used to fill out the packet.
+The options are as follows:
+.Bl -tag -width indent
+.It Fl A
+Audible.
+Output a bell
+.Tn ( ASCII
+0x07)
+character when no packet is received before the next packet
+is transmitted.
+To cater for round-trip times that are longer than the interval
+between transmissions, further missing packets cause a bell only
+if the maximum number of unreceived packets has increased.
+.It Fl a
+Audible.
+Include a bell
+.Tn ( ASCII
+0x07)
+character in the output when any packet is received.
+This option is ignored
+if other format options are present.
+.It Fl b Ar boundif
+Bind the socket to interface
+.Ar boundif
+for sending.
+.It Fl c Ar count
+Stop after sending
+(and receiving)
+.Ar count
+.Tn ECHO_RESPONSE
+packets.
+If this option is not specified,
+.Nm
+will operate until interrupted.
+If this option is specified in conjunction with ping sweeps,
+each sweep will consist of
+.Ar count
+packets.
+.It Fl D
+Set the Don't Fragment bit.
+.It Fl d
+Set the
+.Dv SO_DEBUG
+option on the socket being used.
+.It Fl f
+Flood ping.
+Outputs packets as fast as they come back or one hundred times per second,
+whichever is more.
+For every
+.Tn ECHO_REQUEST
+sent a period
+.Dq .\&
+is printed, while for every
+.Tn ECHO_REPLY
+received a backspace is printed.
+This provides a rapid display of how many packets are being dropped.
+Only the super-user may use this option.
+.Bf -emphasis
+This can be very hard on a network and should be used with caution.
+.Ef
+.It Fl G Ar sweepmaxsize
+Specify the maximum size of
+.Tn ICMP
+payload when sending sweeping pings.
+This option is required for ping sweeps.
+.It Fl g Ar sweepminsize
+Specify the size of
+.Tn ICMP
+payload to start with when sending sweeping pings.
+The default value is 0.
+.It Fl h Ar sweepincrsize
+Specify the number of bytes to increment the size of
+.Tn ICMP
+payload after
+each sweep when sending sweeping pings. The default value is 1.
+.It Fl I Ar iface
+Source multicast packets with the given interface address.
+This flag only applies if the ping destination is a multicast address.
+.It Fl i Ar wait
+Wait
+.Ar wait
+seconds
+.Em between sending each packet .
+The default is to wait for one second between each packet.
+The wait time may be fractional, but only the super-user may specify
+values less than 1 second.
+This option is incompatible with the
+.Fl f
+option.
+.It Fl L
+Suppress loopback of multicast packets.
+This flag only applies if the ping destination is a multicast address.
+.It Fl l Ar preload
+If
+.Ar preload
+is specified,
+.Nm
+sends that many packets as fast as possible before falling into its normal
+mode of behavior.
+Only the super-user may use this option.
+.It Fl M Cm mask | time
+Use
+.Dv ICMP_MASKREQ
+or
+.Dv ICMP_TSTAMP
+instead of
+.Dv ICMP_ECHO .
+For
+.Cm mask ,
+print the netmask of the remote machine.
+Set the
+.Va net.inet.icmp.maskrepl
+MIB variable to enable
+.Dv ICMP_MASKREPLY .
+For
+.Cm time ,
+print the origination, reception and transmission timestamps.
+.It Fl m Ar ttl
+Set the IP Time To Live for outgoing packets.
+If not specified, the kernel uses the value of the
+.Va net.inet.ip.ttl
+MIB variable.
+.It Fl n
+Numeric output only.
+No attempt will be made to lookup symbolic names for host addresses.
+.It Fl o
+Exit successfully after receiving one reply packet.
+.It Fl P Ar policy
+.Ar policy
+specifies IPsec policy for the ping session.
+For details please refer to
+.Xr ipsec 4
+and
+.Xr ipsec_set_policy 3 .
+.It Fl p Ar pattern
+You may specify up to 16
+.Dq pad
+bytes to fill out the packet you send.
+This is useful for diagnosing data-dependent problems in a network.
+For example,
+.Dq Li \-p ff
+will cause the sent packet to be filled with all
+ones.
+.It Fl Q
+Somewhat quiet output.
+.No Don Ap t
+display ICMP error messages that are in response to our query messages.
+Originally, the
+.Fl v
+flag was required to display such errors, but
+.Fl v
+displays all ICMP error messages.
+On a busy machine, this output can be overbearing.
+Without the
+.Fl Q
+flag,
+.Nm
+prints out any ICMP error messages caused by its own ECHO_REQUEST
+messages.
+.It Fl q
+Quiet output.
+Nothing is displayed except the summary lines at startup time and
+when finished.
+.It Fl R
+Record route.
+Includes the
+.Tn RECORD_ROUTE
+option in the
+.Tn ECHO_REQUEST
+packet and displays
+the route buffer on returned packets.
+Note that the IP header is only large enough for nine such routes;
+the
+.Xr traceroute 8
+command is usually better at determining the route packets take to a
+particular destination.
+If more routes come back than should, such as due to an illegal spoofed
+packet, ping will print the route list and then truncate it at the correct
+spot.
+Many hosts ignore or discard the
+.Tn RECORD_ROUTE
+option.
+.It Fl r
+Bypass the normal routing tables and send directly to a host on an attached
+network.
+If the host is not on a directly-attached network, an error is returned.
+This option can be used to ping a local host through an interface
+that has no route through it
+(e.g., after the interface was dropped by
+.Xr routed 8 ) .
+.It Fl S Ar src_addr
+Use the following IP address as the source address in outgoing packets.
+On hosts with more than one IP address, this option can be used to
+force the source address to be something other than the IP address
+of the interface the probe packet is sent on.
+If the IP address
+is not one of this machine's interface addresses, an error is
+returned and nothing is sent.
+.It Fl s Ar packetsize
+Specify the number of data bytes to be sent.
+The default is 56, which translates into 64
+.Tn ICMP
+data bytes when combined
+with the 8 bytes of
+.Tn ICMP
+header data.
+This option cannot be used with ping sweeps.
+.It Fl T Ar ttl
+Set the IP Time To Live for multicasted packets.
+This flag only applies if the ping destination is a multicast address.
+.It Fl t Ar timeout
+Specify a timeout, in seconds, before ping exits regardless of how
+many packets have been received.
+.It Fl v
+Verbose output.
+.Tn ICMP
+packets other than
+.Tn ECHO_RESPONSE
+that are received are listed.
+.It Fl W Ar waittime
+Time in milliseconds to wait for a reply for each packet sent.
+If a reply arrives later, the packet is not printed as replied, but
+considered as replied when calculating statistics.
+.It Fl z Ar tos
+Use the specified type of service.
+.El
+.Pp
+When using
+.Nm
+for fault isolation, it should first be run on the local host, to verify
+that the local network interface is up and running.
+Then, hosts and gateways further and further away should be
+.Dq pinged .
+Round-trip times and packet loss statistics are computed.
+If duplicate packets are received, they are not included in the packet
+loss calculation, although the round trip time of these packets is used
+in calculating the round-trip time statistics.
+When the specified number of packets have been sent
+(and received)
+or if the program is terminated with a
+.Dv SIGINT ,
+a brief summary is displayed, showing the number of packets sent and
+received, and the minimum, mean, maximum, and standard deviation of
+the round-trip times.
+.Pp
+If
+.Nm
+receives a
+.Dv SIGINFO
+(see the
+.Cm status
+argument for
+.Xr stty 1 )
+signal, the current number of packets sent and received, and the
+minimum, mean, and maximum of the round-trip times will be written to
+the standard error output.
+.Pp
+This program is intended for use in network testing, measurement and
+management.
+Because of the load it can impose on the network, it is unwise to use
+.Nm
+during normal operations or from automated scripts.
+.Sh ICMP PACKET DETAILS
+An IP header without options is 20 bytes.
+An
+.Tn ICMP
+.Tn ECHO_REQUEST
+packet contains an additional 8 bytes worth of
+.Tn ICMP
+header followed by an arbitrary amount of data.
+When a
+.Ar packetsize

+(the default is 56).
+Thus the amount of data received inside of an IP packet of type
+.Tn ICMP
+.Tn ECHO_REPLY
+will always be 8 bytes more than the requested data space
+(the
+.Tn ICMP
+header).
+.Pp
+If the data space is at least eight bytes large,
+.Nm
+uses the first eight bytes of this space to include a timestamp which
+it uses in the computation of round trip times.
+If less than eight bytes of pad are specified, no round trip times are

sends that many packets as fast as possible before falling into its normal
mode of behavior.
Only the super-user may use this option.
+.It Fl m
+By default,
+.Nm
+asks the kernel to fragment packets to fit into the minimum IPv6 MTU.
+The
+.Fl m
+option
+will suppress the behavior in the following two levels:
+when the option is specified once, the behavior will be disabled for

+The

+utility
+is intentionally separate from
+.Xr ping 8 .
+.Pp
There have been many discussions on why we separate
-.Xr ping6 8
+.Nm
and
.Xr ping 8 .
Some people argued that it would be more convenient to uniform the
.Fl 4
option (or something like those) to specify the particular address family.
This essentially means that we have two different commands.

-.Sh DESCRIPTION
-.Nm Routed
-is a daemon invoked at boot time to manage the network
-routing tables.
-It uses Routing Information Protocol, RIPv1 (RFC\ 1058),
-RIPv2 (RFC\ 1723),
-and Internet Router Discovery Protocol (RFC 1256)
-to maintain the kernel routing table.
-The RIPv1 protocol is based on the reference 4.3BSD daemon.
-.Pp
-It listens on the
-.Xr udp 4
-socket for the
-.Xr route 8
-service (see
-.Xr services 5 )
-for Routing Information Protocol packets.
-It also sends and receives multicast Router Discovery ICMP messages.
-If the host is a router,
-.Nm
-periodically supplies copies
-of its routing tables to any directly connected hosts and networks.
-It also advertise or solicits default routes using Router Discovery
-ICMP messages.
-.Pp
-When started (or when a network interface is later turned on),
-.Nm
-uses an AF_ROUTE address family facility to find those
-directly connected interfaces configured into the
-system and marked "up".
-It adds necessary routes for the interfaces
-to the kernel routing table.
-Soon after being first started, and provided there is at least one
-interface on which RIP has not been disabled,
-.Nm
-deletes all pre-existing
-non-static routes in kernel table.
-Static routes in the kernel table are preserved and
-included in RIP responses if they have a valid RIP metric
-(see
-.Xr route 8 ).
-.Pp
-If more than one interface is present (not counting the loopback interface),
-it is assumed that the host should forward packets among the
-connected networks.
-After transmitting a RIP
-.Em request
-and
-Router Discovery Advertisements or Solicitations on a new interface,
-the daemon enters a loop, listening for
-RIP request and response and Router Discover packets from other hosts.
-.Pp
-When a
-.Em request
-packet is received,
-.Nm
-formulates a reply based on the information maintained in its
-internal tables.
-The
-.Em response
-packet generated contains a list of known routes, each marked
-with a "hop count" metric (a count of 16 or greater is
-considered "infinite").
-Advertised metrics reflect the metric associated with interface
-(see
-.Xr ifconfig 8 ),
-so setting the metric on an interface
-is an effective way to steer traffic.
-.Pp
-Responses do not contain routes with a first hop on the requesting
-network to implement in part
-.Em split-horizon .
-.Pp
-The routing table maintained by the daemon
-includes space for several gateways for each destination
-to speed recovery from a failing router.
-RIP
-.Em response
-packets received are used to update the routing tables provided they are
-from one of the several currently recognized gateways or
-advertise a better metric than at least one of the existing
-gateways.
-.Pp
-When an update is applied,
-.Nm
-records the change in its own tables and updates the kernel routing table
-if the best route to the destination changes.
-The change in the kernel routing table is reflected in the next batch of
-.Em response
-packets sent.
-If the next response is not scheduled for a while, a
-.Em flash update
-response containing only recently changed routes is sent.
-.Pp
-In addition to processing incoming packets,
-.Nm
-also periodically checks the routing table entries.
-If an entry has not been updated for 3 minutes, the entry's metric
-is set to infinity and marked for deletion.
-Deletions are delayed until the route has been advertised with
-an infinite metric to insure the invalidation
-is propagated throughout the local internet.
-This is a form of
-.Em poison reverse .
-.Pp
-Routes in the kernel table that are added or changed as a result
-of ICMP Redirect messages are deleted after a while to minimize
-.Em black-holes .
-When a TCP connection suffers a timeout,
-the kernel tells
-.Nm routed ,
-which deletes all redirected routes
-through the gateway involved, advances the age of all RIP routes through
-the gateway to allow an alternate to be chosen, and advances of the
-age of any relevant Router Discovery Protocol default routes.
-.Pp
-Hosts acting as internetwork routers gratuitously supply their
-routing tables every 30 seconds to all directly connected hosts
-and networks.
-These RIP responses are sent to the broadcast address on nets that support
-broadcasting,
-to the destination address on point-to-point links, and to the router's
-own address on other networks.
-If RIPv2 is enabled, multicast packets are sent on interfaces that
-support multicasting.
-.Pp
-If no response is received on a remote interface, if there are errors
-while sending responses,
-or if there are more errors than input or output (see
-.Xr netstat 8 ),
-then the cable or some other part of the interface is assumed to be
-disconnected or broken, and routes are adjusted appropriately.
-.Pp
-The
-.Em Internet Router Discovery Protocol
-is handled similarly.
-When the daemon is supplying RIP routes, it also listens for
-Router Discovery Solicitations and sends Advertisements.
-When it is quiet and only listening to other RIP routers, it
-sends Solicitations and listens for Advertisements.
-If it receives
-a good Advertisement, it stops listening for broadcast or multicast
-RIP responses.
-It tracks several advertising routers to speed recovery when the
-currently chosen router dies.
-If all discovered routers disappear,
-the daemon resumes listening to RIP responses.
-.Pp
-While using Router Discovery (which happens by default when
-the system has a single network interface and a Router Discover Advertisement
-is received), there is a single default route and a variable number of
-redirected host routes in the kernel table.
-.Pp
-The Router Discover standard requires that advertisements
-have a default "lifetime" of 30 minutes. That means should
-something happen, a client can be without a good route for
-30 minutes. It is a good idea to reduce the default to 45
-seconds using
-.Fl P Cm rdisc_interval=45
-on the command line or
-.Cm rdisc_interval=45
-in the
-.Pa /etc/gateways
-file.
-.Pp
-See the
-.Cm pm_rdisc
-facility described below to support "legacy" systems
-that can handle neither RIPv2 nor Router Discovery.
-.Pp
-By default, neither Router Discovery advertisements nor solicitations
-are sent over point to point links (e.g. PPP).
-.Pp
-Options supported by
-.Nm routed :
-.Bl -tag -width Ds
-.It Fl s
-this option forces
-.Nm
-to supply routing information.
-This is the default if multiple network interfaces are present on which
-RIP or Router Discovery have not been disabled, and if the kernel switch
-ipforwarding=1.
-.It Fl q
-is the opposite of the
-.Fl s
-option.
-.It Fl d
-Do not run in the background.
-This option is meant for interactive use.
-.It Fl g
-This flag is used on internetwork routers to offer a route
-to the "default" destination.
-It is equivalent to
-.Fl F
-.Cm 0/0,1
-and is present mostly for historical reasons.
-A better choice is
-.Fl P Cm pm_rdisc
-on the command line or
-.Cm pm_rdisc in the
-.Pa /etc/gateways
-file.
-since a larger metric
-will be used, reducing the spread of the potentially dangerous
-default route.
-This is typically used on a gateway to the Internet,
-or on a gateway that uses another routing protocol whose routes
-are not reported to other local routers.
-Notice that because a metric of 1 is used, this feature is
-dangerous. It is more commonly accidently used to create chaos with routing
-loop than to solve problems.
-.It Fl h
-This causes host or point-to-point routes to not be advertised,
-provided there is a network route going the same direction.
-That is a limited kind of aggregation.
-This option is useful on gateways to ethernets that have other gateway
-machines connected with point-to-point links such as SLIP.
-.It Fl m
-This causes the machine to advertise a host or point-to-point route to
-its primary interface.
-It is useful on multi-homed machines such as NFS servers.
-This option should not be used except when the cost of
-the host routes it generates is justified by the popularity of
-the server.
-It is effective only when the machine is supplying
-routing information, because there is more than one interface.
-The
-.Fl m
-option overrides the
-.Fl q
-option to the limited extent of advertising the host route.
-.It Fl A
-do not ignore RIPv2 authentication if we do not care about RIPv2
-authentication.
-This option is required for conformance with RFC 1723.
-However, it makes no sense and breaks using RIP as a discovery protocol
-to ignore all RIPv2 packets that carry authentication when this machine
-does not care about authentication.
-.It Fl T Ar tracefile
-increases the debugging level to at least 1 and
-causes debugging information to be appended to the trace file.
-Note that because of security concerns, it is wisest to not run
-.Nm routed
-routinely with tracing directed to a file.
-.It Fl t
-increases the debugging level, which causes more information to be logged
-on the tracefile specified with
-.Fl T
-or standard out.
-The debugging level can be increased or decreased
-with the
-.Em SIGUSR1
-or
-.Em SIGUSR2
-signals.
-.It Fl F Ar net[/mask][,metric]
-minimize routes in transmissions via interfaces with addresses that match
-.Em net/mask ,
-and synthesizes a default route to this machine with the
-.Em metric .
-The intent is to reduce RIP traffic on slow, point-to-point links
-such as PPP links by replacing many large UDP packets of RIP information
-with a single, small packet containing a "fake" default route.
-If
-.Em metric
-is absent, a value of 14 is assumed to limit
-the spread of the "fake" default route.
-This is a dangerous feature that when used carelessly can cause routing
-loops.
-Notice also that more than one interface can match the specified network
-number and mask.
-See also
-.Fl g .
-.It Fl P Ar parms
-is equivalent to adding the parameter
-line
-.Em parms
-to the
-.Pa /etc/gateways
-file.
-.El
-.Pp
-Any other argument supplied is interpreted as the name
-of a file in which the actions of
-.Nm
-should be logged.
-It is better to use
-.Fl T
-instead of
-appending the name of the trace file to the command.
-.Pp
-.Nm
-also supports the notion of
-"distant"
-.Em passive
-or
-.Em active
-gateways.
-When
-.Nm
-is started, it reads the file
-.Pa /etc/gateways
-to find such distant gateways which may not be located using
-only information from a routing socket, to discover if some
-of the local gateways are
-.Em passive ,
-and to obtain other parameters.
-Gateways specified in this manner should be marked passive
-if they are not expected to exchange routing information,
-while gateways marked active
-should be willing to exchange RIP packets.
-Routes through
-.Em passive
-gateways are installed in the
-kernel's routing tables once upon startup and are not included in
-transmitted RIP responses.
-.Pp
-Distant active gateways are treated like network interfaces.
-RIP responses are sent
-to the distant
-.Em active
-gateway.
-If no responses are received, the associated route is deleted from
-the kernel table and RIP responses advertised via other interfaces.
-If the distant gateway resumes sending RIP responses, the associated
-route is restored.
-.Pp
-Such gateways can be useful on media that do not support broadcasts
-or multicasts but otherwise act like classic shared media like
-Ethernets such as some ATM networks.
-One can list all RIP routers reachable on the ATM network in
-.Pa /etc/gateways
-with a series of
-"host" lines.
-.Pp
-Gateways marked
-.Em external
-are also passive, but are not placed in the kernel
-routing table nor are they included in routing updates.
-The function of external entries is to indicate
-that another routing process
-will install such a route if necessary,
-and that alternate routes to that destination should not be installed
-by
-.Nm routed .
-Such entries are only required when both routers may learn of routes
-to the same destination.
-.Pp
-The
-.Pa /etc/gateways
-file is comprised of a series of lines, each in
-one of the following formats or consist of parameters described below:
-.Pp
-.Bd -ragged
-.Cm net
-.Ar Nname[/mask]
-.Cm gateway
-.Ar Gname
-.Cm metric
-.Ar value
-.Pf < Cm passive No \&|
-.Cm active No \&|
-.Cm extern Ns >
-.Ed
-.Bd -ragged
-.Cm host
-.Ar Hname
-.Cm gateway
-.Ar Gname
-.Cm metric
-.Ar value
-.Pf < Cm passive No \&|
-.Cm active No \&|
-.Cm extern Ns >
-.Ed
-.Pp
-.Ar Nname
-or
-.Ar Hname
-is the name of the destination network or host.
-It may be a symbolic network name or an Internet address
-specified in "dot" notation (see
-.Xr inet 3 ).
-(If it is a name, then it must either be defined in
-.Pa /etc/networks
-or
-.Pa /etc/hosts ,
-or
-.Xr named 8 ,
-must have been started before
-.Nm routed Ns .)
-.Pp
-.Ar mask
-is an optional number between 1 and 32 indicating the netmask associated
-with
-.Ar Nname .
-.Pp
-.Ar Gname
-is the name or address of the gateway to which RIP responses should
-be forwarded.
-.Pp
-.Ar Value
-is the hop count to the destination host or network.
-.Ar " host hname "
-is equivalent to
-.Ar " net nname/32 ".
-.Pp
-One of the keywords
-.Cm passive ,
-.Cm active
-or
-.Cm external
-must be present to indicate whether the gateway should be treated as
-.Cm passive
-or
-.Cm active
-(as described above),
-or whether the gateway is
-.Cm external
-to the scope of the RIP protocol.
-.Pp
-Lines that start with neither "net" nor "host" must consist of one
-or more of the following parameter settings, separated by commas or
-blanks:
-.Bl -tag -width Ds
-.It Cm if Ns \&= Ns Ar ifname
-indicates that the other parameters on the line apply to the interface
-name
-.Ar ifname .
-.It Cm subnet Ns \&= Ns Ar nname[/mask][,metric]
-advertises a route to network
-.Ar nname
-with mask
-.Ar mask
-and the supplied metric (default 1).
-This is useful for filling "holes" in CIDR allocations.
-This parameter must appear by itself on a line.
-.Pp
-Do not use this feature unless necessary. It is dangerous.
-.It Cm passwd Ns \&= Ns Ar XXX
-specifies a RIPv2 password that will be included on all RIPv2
-responses sent and checked on all RIPv2 responses received.
-The password must not contain any blanks, tab characters, commas
-or '#' characters.
-.It Cm no_ag
-turns off aggregation of subnets in RIPv1 and RIPv2 responses.
-.It Cm no_super_ag
-turns off aggregation of networks into supernets in RIPv2 responses.
-.It Cm passive
-is equivalent
-.Cm no_rip Cm no_rdisc .
-.It Cm no_rip
-disables all RIP processing on the specified interface.
-If no interfaces are allowed to process RIP packets,
-.Nm
-acts purely as a router discovery daemon.
-.Cm No_rip
-is equivalent to
-.Cm no_ripv1_in no_ripv2_in no_ripv1_out no_ripv2_out .
-.Pp
-Note that turning off RIP without explicitly turning on router
-discovery advertisements with
-.Cm rdisc_adv
-or
-.Fl s
-causes
-.Nm routed
-to act as a client router discovery daemon, not advertising.
-.It Cm no_ripv1_in
-causes RIPv1 received responses to be ignored.
-.It Cm no_ripv2_in
-causes RIPv2 received responses to be ignored.
-.It Cm ripv2_out
-turns off RIPv1 output and causes RIPv2 advertisements to be
-multicast when possible.
-.It Cm no_rdisc
-disables the Internet Router Discovery Protocol.
-.It Cm no_solicit
-disables the transmission of Router Discovery Solicitations.
-.It Cm send_solicit
-specifies that Router Discovery solicitations should be sent,
-even on point-to-point links,
-which by default only listen to Router Discovery messages.
-.It Cm no_rdisc_adv
-disables the transmission of Router Discovery Advertisements
-.It Cm rdisc_adv
-specifies that Router Discovery advertisements should be sent,
-even on point-to-point links,
-which by default only listen to Router Discovery messages
-.It Cm bcast_rdisc
-specifies that Router Discovery packets should be broadcast instead of
-multicast.
-.It Cm rdisc_pref Ns \&= Ns Ar N
-sets the preference in Router Discovery Advertisements to the integer
-.Ar N .
-.It Cm rdisc_interval Ns \&= Ns Ar N
-sets the nominal interval with which Router Discovery Advertisements
-are transmitted to N seconds and their lifetime to 3*N.
-.It Cm fake_default Ns \&= Ns Ar metric
-has an identical effect to
-.Fl F Ar net[/mask][,metric]
-with the network and mask coming from the specified interface.
-.It Cm pm_rdisc
-is similar to
-.Cm fake_default .
-When RIPv2 routes are multicast, so that RIPv1 listeners cannot
-receive them, this feature causes a RIPv1 default route to be
-broadcast to RIPv1 listeners.
-Unless modified with
-.Cm fake_default ,
-the default route is broadcast with a metric of 14.
-That serves as a "poor man's router discovery" protocol.
-.El
-.Pp
-Note that the netmask associated with point-to-point links (such as SLIP
-or PPP, with the IFF_POINTOPOINT flag) is used by
-.Nm routed
-to infer the netmask used by the remote system when RIPv1 is used.

-.Nd attach serial lines as network interfaces
-.Sh SYNOPSIS
-.Nm Slattach
-.Ar ttyname Op Ar baudrate
-.Sh DESCRIPTION
-.Nm Slattach
-is used to assign a tty line to a network interface,
-and to define the network source and destination addresses.
-The following operands are supported by
-.Nm slattach :
-.Bl -tag -width Ar
-.It Ar ttyname
-Specifies the name of the tty device.
-.Ar Ttyname
-should be a string of the form
-.Ql ttyXX ,
-or
-.Ql /dev/ttyXX .
-.It Ar baudrate
-Specifies the speed of the connection. If not specified, the
-default of 9600 is used.
-.El
-.Pp
-Only the super-user may attach a network interface.
-.Pp
-To detach the interface, use
-.Dq Li ifconfig interface-name down
-after killing off the
-.Nm slattach
-process.
-.Ar Interface-name
-is the name that is shown by
-.Xr netstat 1
-.Sh EXAMPLES
-.Bd -literal -offset indent -compact
-slattach ttyh8
-slattach /dev/tty01 4800
-.Ed
-.Sh DIAGNOSTICS
-Messages indicating the specified interface does not exit, the
-requested address is unknown, the user is not privileged and
-tried to alter an interface's configuration.
-.Sh SEE ALSO
-.Xr netstat 1 ,

+Turn on AS# lookups and use the given server instead of the
+default.
+.It Fl d
+Enable socket level debugging.
+.It Fl D
+When an ICMP response to our probe datagram is received,
+print the differences between the transmitted packet and
+the packet quoted by the ICMP response.
+A key showing the location of fields within the transmitted packet is printed,
+followed by the original packet in hex,
+followed by the quoted packet in hex.
+Bytes that are unchanged in the quoted packet are shown as underscores.
+Note,
+the IP checksum and the TTL of the quoted packet are not expected to match.
+By default, only one probe per hop is sent with this option.
+.It Fl e
+Firewall evasion mode.
+Use fixed destination ports for UDP and TCP probes.
+The destination port does NOT increment with each packet sent.
.It Fl f Ar first_ttl
Set the initial time-to-live used in the first outgoing probe packet.

the default is to not calculate checksums and using

length. I.e., rip is really only 7 hops away. A reply that
returns with a ttl of 1 is a clue this problem exists.

.Pp
This program is intended for use in network testing, measurement
and management.
It should be used primarily for manual fault isolation.
Because of the load it could impose on the network, it is unwise to use
-.Nm traceroute
+.Nm
during normal operations or from automated scripts.
.Sh AUTHOR
Implemented by Van Jacobson from a suggestion by Steve Deering. Debugged
.Nm
should listen for a RST from the destination host (or an intermediate
router that's filtering packets), but this is not implemented yet.

+The AS number capability reports information that may sometimes be
+inaccurate due to discrepancies between the contents of the
+routing database server and the current state of the Internet.

.Sh DESCRIPTION
+The
+.Nm
+utility
+uses the IPv6 protocol hop limit field to elicit an ICMPv6 TIME_EXCEEDED
+response from each gateway along the path to some host.
+.Pp
+The only mandatory parameter is the destination host name or IPv6 address.
+The default probe datagram carries 12 bytes of payload,
+in addition to the IPv6 header.
+The size of the payload can be specified by giving a length
+(in bytes)
+after the destination host name.
+.Pp
+Other options are:
.Bl -tag -width Ds
.It Fl d
Debug mode.
Specify intermediate gateway
.Nm (
uses routing header).
-.It Fl m Ar hoplimit
-Specify maximum hoplimit.
+.It Fl I
+Use ICMP6 ECHO instead of UDP datagrams.
.It Fl l
Print both host hostnames and numeric addresses.
Normally
is not specified, and only numeric addresses if
.Fl n
is specified.
+.It Fl m Ar hoplimit
+Specify maximum hoplimit, up to 255.
+The default is 30 hops.
.It Fl n
Do not resolve numeric address to hostname.
+.It Fl N
+Use a packet with no upper layer header for the probes,
+instead of UDP datagrams.
.It Fl p Ar port
Set UDP port number to
.Ar port .
Set the number of probe per hop count to
.Ar probes .
.It Fl r
+Bypass the normal routing tables and send directly to a host
+on an attached network.
+If the host is not on a directly-connected network,
+an error is returned.
+This option corresponds to the
+.Dv SO_DONTROUTE
+socket option;
+it can be used to ping a local host through an interface
+that has no route through it
+(e.g., after the interface was dropped by a routing daemon).
.It Fl s Ar src
.Ar Src
specifies the source IPv6 address to be used.
+.It Fl U
+Use UDP datagrams for the probes.
+This is the default.
.It Fl v
Be verbose.
.It Fl w Ar waittime
Specify the delay time between probes.
.El
+.Pp
+This program prints the route to the given destination and the round-trip
+time to each gateway, in the same manner as traceroute.
+.Pp
+Here is a list of possible annotations after the round-trip time for each gateway:
+.Bl -hang -offset indent
+.It !N
+Destination Unreachable - No Route to Host.
+.It !P
+Destination Unreachable - Administratively Prohibited.
+.It !S
+Destination Unreachable - Not a Neighbour.
+.It !A
+Destination Unreachable - Address Unreachable.
+.It !\&
+This is printed if the hop limit is <= 1 on a port unreachable message.
+This means that the packet got to the destination,
+but that the reply had a hop limit that was just large enough to
+allow it to get back to the source of the traceroute6.
+This was more interesting in the IPv4 case,
+where some IP stack bugs could be identified by this behaviour.

-.Sh NAME
-.Nm trpt
-.Nd transliterate protocol trace
-.Sh SYNOPSIS
-.Nm trpt
-.Op Fl a
-.Op Fl f
-.Op Fl j
-.Op Fl p Ar hex-address
-.Op Fl s
-.Op Fl t
-.Oo
-.Ar system Op Ar core
-.Oc
-.Sh DESCRIPTION
-.Nm Trpt
-interrogates the buffer of
-.Tn TCP
-trace records created
-when a socket is marked for
-.Dq debugging
-(see
-.Xr setsockopt 2 ) ,
-and prints a readable description of these records.
-When no options are supplied,
-.Nm trpt
-prints all the trace records found in the system
-grouped according to
-.Tn TCP
-connection protocol control
-block
-.Pq Tn PCB .
-The following options may be used to
-alter this behavior.
-.Bl -tag -width Ds
-.It Fl a
-In addition to the normal output,
-print the values of the source and destination
-addresses for each packet recorded.
-.It Fl f
-Follow the trace as it occurs, waiting a short time for additional records
-each time the end of the log is reached.
-.It Fl j
-Just give a list of the protocol control block
-addresses for which there are trace records.
-.It Fl p
-Show only trace records associated with the protocol
-control block at the given address
-.Ar hex-address .
-.It Fl s
-In addition to the normal output,
-print a detailed description of the packet
-sequencing information.
-.It Fl t
-in addition to the normal output,
-print the values for all timers at each
-point in the trace.
-.El
-.Pp
-The recommended use of
-.Nm trpt
-is as follows.
-Isolate the problem and enable debugging on the
-socket(s) involved in the connection.
-Find the address of the protocol control blocks
-associated with the sockets using the
-.Fl A
-option to
-.Xr netstat 1 .
-Then run
-.Nm trpt
-with the
-.Fl p
-option, supplying the associated
-protocol control block addresses.
-The
-.Fl f
-option can be used to follow the trace log once the trace is located.
-If there are
-many sockets using the debugging option, the
-.Fl j
-option may be useful in checking to see if
-any trace records are present for the socket in
-question.
-.Pp
-If debugging is being performed on a system or
-core file other than the default, the last two
-arguments may be used to supplant the defaults.
-.Sh FILES
-.Bl -tag -width /dev/kmem -compact
-.It Pa /vmunix
-.It Pa /dev/kmem
-.El
-.Sh SEE ALSO
-.Xr netstat 1 ,
-.Xr setsockopt 2 ,
-.Xr trsp 8
-.Sh DIAGNOSTICS
-.Bl -tag -width Ds
-.It Sy no namelist
-When the system image doesn't
-contain the proper symbols to find the trace buffer;
-others which should be self explanatory.
-.El
-.Sh BUGS
-Should also print the data for each input or output,
-but this is not saved in the race record.
-.Pp
-The output format is inscrutable and should be described
-here.
-.Sh HISTORY
-The
-.Nm
-command appeared in
-.Bx 4.2 .
