'Sometimes' is a difficult problem to resolve; can you identify any
particular times when it fails consistently? Also, when you say you 'log
in via LAN', what exactly do you mean - are we talking telnet, Netatalk,
Samba, or just plain DNS, which doesn't really have a sense of loggin in?

I'm afraid I don't know what ndc is or does.

DNS doesn't usually just stop working. Is your Internet link permanent?

As I said, these applications usually don't use syslogd, and so you have
to read each individual log file. 'Accessed' via what service - are you
perhaps talking about people telnetting into your server?
