One other thing: Mail gateways do a lot of nslookup operations, so make sure you run "nscd" (name service cache daemon) and adjust it so it caches more than the default number of hosts. So for example, the one section in /etc/nscd.conf dealing with host names might contain something like this:
enable-cache hosts yes positive-time-to-live hosts 3600 negative-time-to-live hosts 20 suggested-size hosts 1213 check-files hosts yes persistent hosts yes shared hosts yes max-db-size hosts 33554432 The suggested size is usually set to "211" as a default. As to disk I/', I'd definitely run vmstat and iostat to see if the values look reasonable. I'd also run "swapon -s" to make sure you have enough swap space, and of course "top" to get a general idea of how your systems are running. --Tobias ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
