ipsvd - Internet protocol service daemon
ipsvd [-hp] [-l
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
Currently there are two implementations of an internet protocol service
a TCP/IP service daemon,
and an UDP/IP service daemon,
More internet protocol service daemons may appear in the future.
-i dir ||
read instructions for handling new connections from the instructions
-x cdb ||
read instructions for handling new connections from the constant database
cdb. The constant database normally is created from an instructions directory by
-t sec ||
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 wasnt accessed within the last
ipsvd does not discard or remove a file if the users write permission is not set,
for those files the timeout is disabled.
Default is 0, which means that the timeout is disabled.
-l name ||
Do not look up the local hostname in DNS, but use
name as hostname.
-u [:]user[:group] |
Set uid and gid to the
users uid and gid, as found in
/etc/passwd, before running
user is followed by a colon and a
group, set the gid to
groups gid, as found in
/etc/group, instead of
group consists of a colon-separated list of group names,
set the group ids of all listed groups.
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.
Look up the clients hostname in DNS.
After looking up the clients 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 clients IP address.
You should set this option if you use hostname based instructions.
The -p option implies the -h option.
ipsvd receives a TERM signal, it exists with 0.
