Signals
The following signals are used to signal sockd:
SIGHUP
Causes sockd to re-read the configuration file. If the new
configuration file fails to parse, the previous configuration remains intact.
SIGINT
Indicates that the log file has moved, and sockd should reopen its log
file. At some point, this will include rewriting the startup lines
for all open connections.
SIGIOT
Indicates that sockd should no longer listen for new connections.
The listen socket is closed (meaning that a new daemon can be launched.)
SIGTERM
Close all connections and terminate.
SIGUSR1
Dump client information.
XXX - not implemented
SIGUSR2
Dump configuration. This is done in a format that can be fed back
in as a configuration file, albeit not identical to the one that was read.
