       ipsvd - Internet protocol service daemon


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


       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.


       -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.


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