-net removed. -hackers left (although this might be more of a

"Hostname does not match their IP?" What exactly does that mean? All
the OS knows is the remote IP address. It doesn't know what hostname
the remote claims to have. The application server might receive a
hostname though, but then I would expect the behavior to vary
according to the application used to connect.

Something is generating a message to syslogd(8). Figure out what it is
and edit syslog.conf(5) appropriately. Are you using TCP wrappers or
something?

Strange. What does 'netstat -a' or 'sockstat' report? 'w' works fine
for me.
