imgssapi: GSSAPI Syslog Input Module

Provides the ability to receive syslog messages from the network protected via Kerberos 5 encryption and authentication. This module also accept plain tcp syslog messages on the same port if configured to do so. If you need just plain tcp, use imtcp instead.

Note: This is a contributed module, which is not supported by the rsyslog team. We recommend to use RFC5425 TLS-protected syslog instead.

Configuration Directives

$InputGSSServerRun <port>

Starts a GSSAPI server on selected port - note that this runs independently from the TCP server.

$InputGSSServerServiceName <name>

The service name to use for the GSS server.

$InputGSSServerPermitPlainTCP on|off

Permits the server to receive plain tcp syslog (without GSS) on the same port

$InputGSSServerMaxSessions <number>

Sets the maximum number of sessions supported

$InputGSSServerKeepAlive on|off

Requires: 8.5.0 or above

Default: off

Enables or disable keep-alive handling.

Caveats/Known Bugs

  • module always binds to all interfaces
  • only a single listener can be bound

Example

This sets up a GSS server on port 1514 that also permits to receive plain tcp syslog messages (on the same port):

$ModLoad imgssapi # needs to be done just once
$InputGSSServerRun 1514
$InputGSSServerPermitPlainTCP on
