-# CLASSES - Class implementation files in project.
-# HFILES - Header files in project.
-# MFILES - Other Objective-C source files in project.
-# CFILES - Other C source files in project.
-# PSWFILES - .psw files in the project
-# PSWMFILES - .pswm files in the project
-# SUBPROJECTS - Subprojects of this project
-# BUNDLES - Bundle subprojects of this project

-.Tn DARPA
-port to
-.Tn RPC
-program number mapper
-.Sh SYNOPSIS
-.Nm portmap
-.Op Fl d
-.Sh DESCRIPTION
-.Nm Portmap
-is a server that converts
-.Tn RPC
-program numbers into
-.Tn DARPA
-protocol port numbers.
-It must be running in order to make
-.Tn RPC
-calls.
-.Pp
-When an
-.Tn RPC
-server is started, it will tell
-.Nm portmap
-what port number it is listening to, and what
-.Tn RPC
-program numbers it is prepared to serve.
-When a client wishes to make an
-.Tn RPC
-call to a given program number,
-it will first contact
-.Nm portmap
-on the server machine to determine
-the port number where
-.Tn RPC
-packets should be sent.
-.Pp
-.Nm Portmap
-must be started before any
-.Tn RPC
-servers are invoked.
-.Pp
-Normally
-.Nm portmap
-forks and dissociates itself from the terminal
-like any other daemon.
-.Nm Portmap
-then logs errors using
-.Xr syslog 3 .
-.Pp
-Option available:
-.Bl -tag -width Ds
-.It Fl d
-(debug) prevents
-.Nm portmap
-from running as a daemon,
-and causes errors and debugging information
-to be printed to the standard error output.
-.El
-.Sh SEE ALSO
-.Xr inetd.conf 5 ,
-.Xr rpcinfo 8 ,
-.Xr inetd 8
-.Sh BUGS
-If
-.Nm portmap
-crashes, all servers must be restarted.
-.Sh HISTORY
-The

- * FDDI support for tcpdump, by Jeffrey Mogul [DECWRL], June 1992
- *
- * Based in part on code by Van Jacobson, which bears this note:
- *
- * NOTE: This is a very preliminary hack for FDDI support.
- * There are all sorts of wired in constants & nothing (yet)
- * to print SMT packets as anything other than hex dumps.
- * Most of the necessary changes are waiting on my redoing
- * the "header" that a kernel fddi driver supplies to bpf: I
- * want it to look like one byte of 'direction' (0 or 1
- * depending on whether the packet was inbound or outbound),
- * two bytes of system/driver dependent data (anything an
- * implementor thinks would be useful to filter on and/or
- * save per-packet, then the real 21-byte FDDI header.
- * Steve McCanne & I have also talked about adding the
- * 'direction' byte to all bpf headers (e.g., in the two
- * bytes of padding on an ethernet header). It's not clear
- * we could do this in a backwards compatible way & we hate
- * the idea of an incompatible bpf change. Discussions are
- * proceeding.
- *
- * Also, to really support FDDI (and better support 802.2
- * over ethernet) we really need to re-think the rather simple
- * minded assumptions about fixed length & fixed format link
- * level headers made in gencode.c. One day...

.Sh DESCRIPTION
The
-.Nm telnetd
+.Nm
command is a server which supports the
.Tn DARPA
standard
The
.Fl debug
option may be used to start up
-.Nm telnetd
+.Nm
manually, instead of through
.Xr inetd 8 .
-If started up this way,
+If started up this way,
.Ar port
may be specified to run
-.Nm telnetd
+.Nm
on an alternate
.Tn TCP
port number.
.Pp
The
-.Nm telnetd
+.Nm
command accepts the following options:
-.Bl -tag -width "-a authmode"
+.Bl -tag -width indent
.It Fl a Ar authmode
This option may be used for specifying what mode should
be used for authentication.
Note that this option is only useful if
-.Nm telnetd
+.Nm
has been compiled with support for the
.Dv AUTHENTICATION
option.
There are several valid values for
-.Ar authmode:
+.Ar authmode :
.Bl -tag -width debug
-.It debug
-Turns on authentication debugging code.
-.It user
+.It Cm debug
+Turn on authentication debugging code.
+.It Cm user
Only allow connections when the remote user
can provide valid authentication information
to identify the remote user,
and is allowed access to the specified account
without providing a password.
-.It valid

Only allow connections when the remote user
can provide valid authentication information
to identify the remote user.
command will provide any additional user verification
needed if the remote user is not allowed automatic
access to the specified account.
-.It other
+.It Cm other
Only allow connections that supply some authentication information.
This option is currently not supported
by any of the existing authentication mechanisms,
and is thus the same as specifying
.Fl a
.Cm valid .
-.It none
+.It Cm none
This is the default state.
Authentication information is not required.
If no or insufficient authentication information
.Xr login 1
program will provide the necessary user
verification.
-.It off
-This disables the authentication code.
+.It Cm off
+Disable the authentication code.
All user verification will happen through the
.Xr login 1
program.
.El
-.It Fl B
-Specifies bftp server mode. In this mode,
-.Nm telnetd
-causes login to start a
-.Xr bftp 1
-session rather than the user's
-normal shell. In bftp daemon mode normal
-logins are not supported, and it must be used
-on a port other than the normal
-.Tn TELNET
-port.
.It Fl D Ar debugmode
This option may be used for debugging purposes.
This allows
-.Nm telnetd
+.Nm
to print out debugging information
to the connection, allowing the user to see what
-.Nm telnetd
+.Nm
is doing.
-There are several possible values for

has been compiled with support for data encryption, then the
.Fl edebug
option may be used to enable encryption debugging code.
+.It Fl p Ar loginprog

login has been completed.
.It Fl I Ar initid
This option is only applicable to
to use when init starts login sessions. The default
.Dv ID
is
-.Dv fe.
+.Dv fe .
.It Fl k
This option is only useful if
-.Nm telnetd
+.Nm
has been compiled with both linemode and kludge linemode
support. If the
.Fl k
support the
.Dv LINEMODE
option, then
-.Nm telnetd
+.Nm
will operate in character at a time mode.
It will still support kludge linemode, but will only
go into kludge linemode if the remote client requests
it.

.It Fl X Ar authtype
This option is only valid if
-.Nm telnetd

.Sh DESCRIPTION
.Nm Tftpd
is a server which supports the
Internet Trivial File Transfer
-Protocol (\c
-.Tn RFC 783).
+Protocol
+.Pq Tn RFC 1350 .
The
.Tn TFTP
server operates
The use of
.Xr tftp 1
does not require an account or password on the remote system.
-Due to the lack of authentication information,
-.Nm tftpd
+Due to the lack of authentication information,
+.Nm
will allow only publicly readable files to be
accessed.
-Files containing the string ``/\|\fB.\|.\fP\|/'' are not allowed.
+Files containing the string ``/\|\fB.\|.\fP\|/'' or starting with
+``\|\fB.\|.\fP\|/'' are not allowed.
Files may be written only if they already exist and are publicly writable.
Note that this extends the concept of
.Dq public
The server should have the user ID with the lowest possible privilege.
.Pp
Access to files may be restricted by invoking
-.Nm tftpd
+.Nm
with a list of directories by including up to 20 pathnames
as server program arguments in
.Pa /etc/inetd.conf .
In this case access is restricted to files whose
names are prefixed by the one of the given directories.
-The given directories are also treated as a search path for
+The given directories are also treated as a search path for
relative filename requests.
.Pp
+The
+.Fl s
+option provides additional security by changing
+.Nm Ns No 's
+root directory, thereby prohibiting accesses outside of the specified
+.Ar directory .
+Because
+.Xr chroot 2
+requires super-user privileges,
+.Nm
+must be run as root.
+However, after performing the
+.Fn chroot ,
+.Nm
+will set its user id to that of the specified
+.Ar user ,
+or
+.Dq nobody
+if no
+.Fl u
+option is specified.
+.Pp
The options are:
.Bl -tag -width Ds
+.It Fl c
+Changes the default root directory of a connecting host via chroot based on the
+connecting IP address.
+This prevents multiple clients from writing to the same file at the same time.
+If the directory does not exist, the client connection is refused.
+The
+.Fl s
+option is required for
+.Fl c
+and the specified
+.Ar directory
+is used as a base.
+.It Fl C
+Operates the same as
+.Fl c
+except it falls back to
+.Fl s Ns No 's
+.Ar directory
+if a directory does not exist for the client's IP.
