[lug] Lame server on?

[Paul Bille]

Can someone tell me what "Lame server on" means?  Please refer to the
snippet from the log file below.  The problem appears to be on a remote
system so I'm not particularly concerned but I am curious.  Last week I
had a few mail messages addressed to "navigator.org" which apparently
has a "Lame server".  Sendmail tried and tried again to get an MX
record, filling my log file with extraneous error messages.  I finally
had to delete the errant mail messages.

Also, what is the "/sbin/rmmod -as" process that runs every 10 minutes?
Is it necessary to log it?  Is there any way I can control the logging
for this process.

Is there any significance to named cleaning the cache hourly?  Once
again is it necessary to log it?

I had a LINUX 6.2 system hacked with a bind v8.2x overflow this spring.
It's possible that I might have minimized the damage if the log file
contained less extraneous information and the security breach stood out.

Thanks for your help,

Paul
