obsolete legacy directive





The port on which imklog listens for RFC 3195 messages. The default port is 601 (the IANA-assigned port)

Caveats/Known Bugs

Due to no demand at all for RFC3195, we have converted rfc3195d to this input module, but we have NOT conducted any testing. Also, the module does not yet properly handle the recovery case. If someone intends to put this module into production, good testing should be conducted. It also is a good idea to notify the rsyslog project that you intend to use it in production. In this case, we’ll probably give the module another cleanup. We don’t do this now because so far it looks just like a big waste of time.

Currently only a single listener can be defined. That one binds to all interfaces.


The following sample accepts syslog messages via RFC 3195 on port 1601.

$ModLoad im3195
$Input3195ListenPort 1601
