| | 43 | .Sh DESCRIPTION |
| | 44 | .Nm Ypserv |
| | 45 | is a fundamental part of the network information system called YP. |
| | 46 | This server provides information from YP maps to the YP clients |
| | 47 | on the network. |
| | 48 | .Pp |
| | 49 | A YP map is stored on the server as a |
| | 50 | .Xr db 3 |
| | 51 | database. A number of YP maps is grouped together in a domain. |
| | 52 | .Ar Ypserv |
| | 53 | determines the domains it serves by looking for a directory with |
| | 54 | the domain name in |
| | 55 | .Ar /var/yp . |
| | 56 | .Pp |
| | 57 | YP hasn't been known for high security through the years. In recent years |
| | 58 | security has improved by restricting access to the server. In SunOS 4.1 |
| | 59 | has a new file occured named |
| | 60 | .Ar /var/yp/securenet . |
| | 61 | It contains networks the server can assume is secure. For information about |
| | 62 | file format see |
| | 63 | .Xr securenet 5 . |
| | 64 | .Pp |
| | 65 | Before the author of this server had seen |
| | 66 | .Xr securenet 5 |
| | 67 | another format was implemented |
| | 68 | .Xr ypserv.acl 5 . |
| | 69 | This file format makes it possible to allow and deny hosts and networks |
| | 70 | access to the server. This file can have any name since it's given by |
| | 71 | the argument to |
| | 72 | .Fl a |
| | 73 | (use full path). |
| | 74 | .Pp |
| | 75 | The file used can be reread by sending a SIGHUP to ypserv. The process pid |
| | 76 | can be found in the file |
| | 77 | .Nm /var/run/ypserv.pid |
| | 78 | . |
| | 79 | .Pp |
| | 80 | If a host isn't secure all queries to the server will result in a YP_NODOM |
| | 81 | result. |
| | 82 | .Pp |
| | 83 | If the file |
| | 84 | .Nm /var/yp/ypserv.log |
| | 85 | exists then messages will be written to the file. |
| | 86 | .Pp |
| | 87 | If a directory named the same as the system domainname exists in |
| | 88 | .Nm /var/yp/ |
| | 89 | (ie. the domainname is |
| | 90 | .Nm foo |
| | 91 | and directory |
| | 92 | .Nm /var/yp/foo |
| | 93 | exists), then ypserv will be automatically started at boot time. |
| | 94 | .Pp |
| | 95 | The options are as follows: |
| | 96 | .Bl -tag -width indent |
| | 97 | .It Fl 1 |
| | 98 | Allow ypserv to answer old YP version 1 requests. |
| | 99 | .It Fl a Ar aclfile |
| | 100 | Don't use |
| | 101 | .Ar /var/yp/securenet . |
| | 102 | Use another file with another file format. For futher information see |
| | 103 | man page for |
| | 104 | .Ar ypserv.acl . |
| | 105 | .It Fl d |
| | 106 | Use Internet Domain Name System. If a query to map |
| | 107 | .Ar hosts.byname |
| | 108 | or |
| | 109 | .Ar hosts.byaddr |
| | 110 | fails, make a DNS query and return the result if successful. |
| | 111 | Alternately, if these maps were built on the YP master using |
| | 112 | .Nm makedbm |
| | 113 | .Fl b |
| | 114 | then DNS queries will be done without needing to specify |
| | 115 | .Fl d . |
| | 116 | .It Fl x |
| | 117 | Terminate the server after processing |
| | 118 | .Ar aclfile |
| | 119 | or |
| | 120 | .Ar /var/yp/securenet . |
