NAME

       ipsvd - Internet protocol service daemon

SYNOPSIS

       ipsvd [-hp] [-l name] [-u user] [-i dir|-x cdb] [-t sec] host port prog

DESCRIPTION

       An implementation of an internet protocol service daemon provides the command line interface as shown in SYNOPSIS above (additional options
       are possible), and supports pre-defined instructions for handling connections through files in a instructions directory, and through a con-
       stant database, as described in ipsvd-instruct(5).

       Currently  there  are two implementations of an internet protocol service daemon: a TCP/IP service daemon, tcpsvd(8), and an UDP/IP service
       daemon, udpsvd(8).  More internet protocol service daemons may appear in the future.

OPTIONS

       -i dir read instructions for handling new connections from the instructions directory dir.  See ipsvd-instruct(5) for details.

       -x cdb read instructions for handling new connections from the constant database cdb.  The constant database normally is  created  from	an
	      instructions directory by running ipsvd-cdb(8).

       -t sec timeout.	 This  option  only  takes effect if the -i option is given.  While checking the instructions directory, check the time of
	      last access of the file that matches the clients address or hostname if any, discard and remove  the  file  if  it  wasn't  accessed
	      within  the last sec seconds; ipsvd does not discard or remove a file if the user's write permission is not set, for those files the
	      timeout is disabled.  Default is 0, which means that the timeout is disabled.

       -l name
	      local hostname.  Do not look up the local hostname in DNS, but use name as hostname.

       -u [:]user[:group]
	      drop permissions.  Set uid and gid to the user's uid and gid, as found in /etc/passwd, before running prog.  If user is followed	by
	      a  colon and a group, set the gid to group's gid, as found in /etc/group, instead of user's gid.	If group consists of a colon-sepa-
	      rated list of group names, set the group ids of all listed groups.  If user is prefixed with a colon, the user and all  group  argu-
	      ments  are  interpreted as uid and gids respectively, and not looked up in the password or group file.  All supplementary groups are
	      removed.

       -h     Look up the client's hostname in DNS.

       -p     paranoid.  After looking up the client's hostname in DNS, look up the IP addresses in DNS for that hostname, and	forget	about  the
	      hostname if none of the addresses match the client's IP address.	You should set this option if you use hostname based instructions.
	      The -p option implies the -h option.

SIGNALS

       If an ipsvd receives a TERM signal, it exists with 0.
