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.
