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
       constant 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-separated list of group names, set the group ids of all
              listed groups.  If user is prefixed with a colon, the user and
              all group arguments 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.
