NetWare 6.5 SP4a (OES SP1)

What are the error log file default settings? Where are they stored? And
how do I modify them?

The reason I ask is that I need to have this file archive itself (i.e.
create a backup) when it's maximum file size is reached. e.g. SYS$LOG.001
or something similar.

The purpose is to track intruder detection lockouts on the server. We
need to have at least one backup log file, in case the current log file
reaches it's maximum file size before we get a chance to review the file.
