Hi, > I have tcp and udp log_in_vain options enabled in my > kernel. I have noticed a couple odd connection > attempts: > > Connection attempt to UDP 127.0.0.1:512 from > 127.0.0.1:1131 sendmail tries to access a local service called "comsat", on port 512/udp. A workaround is to comment this line in /etc/services: biff 512/udp comsat There is probably something you can configure in sendmail to fix this. Kudos for your paranoia. Keep that up.
