Hi all, have found a couple of other needed changes but added also some other options (TLS, Kerberos) which may be too much but for testing phase may also interesting and a look over worth.
Remote logging with TCP/UDP via syslogdctrl works now which was one of the main intents.
All changes and description can be found in here https://git.ipfire.org/?p=people/ummeegge/ipfire-2.x.git;a=commit;h=81f170ac...
All has been build with origin/next (Core 120).
Greetings,
Erik
