Hello guys,

Thanks for the replies!

Unfortunately I cannot deploy your file edit suggestions. The syslog daemon is set to send the logging directly to ArcSight besides writing it to file. Manipulating the written syslogs is therefore not a valid solution besides the fact this would break security policy because editing a system file before submission will not be accepted, even via (cron)script. They don't really trust us root admins ;-)

I essentially thus really need to be able to change the output of the syslog daemon.

I will check what log level I have set and if your suggested change is something I can test. I will also revert to the OS supplier for checking version and update possibility.

But. Does anyone know about the ssh authentication order and the way that influences the logged message? I found some suggestions online that changing the order would change logged messages?

Best regards,
Sjleegketting.
