Ubuntu Manpage: ipsvd - Internet protocol service daemon

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.
