Syslog Server

This module allows crowdsec to expose a syslog server, and ingest logs directly from another syslog server (or any software that knows how to forward logs with syslog).

Only UDP is supported.

Syslog messages must conform either to RFC3164 or RFC5424, and can be up to 2048 bytes long by default (this value is configurable).
