I just did a port scan on one of my web sites. Shared Hosting. Looking at ports 1863, 3000 and 3001. Are those ports normally open or something I should file a support ticket about? TIA!

Ports are 'open' when you start programs that listen on them. lsof should tell you what those programs are.

Les, I wondered why they have those ports open. 1863 is MSN Messenger. 3000 is RemoteWare Client and 3001 is Redwood Broker. Lanny

Port usage is fairly arbitrary. That is, you can configure most programs to listen on non-standard ports so the actual activity may have nothing to do with the registered name for the port. If you don't have access to find the program using the port you should ask about it.

OK. I think I will put in a support ticket and ask them. It's a shared server, running chrootd. If they can close those 3 ports for this site, it should make it a little bit more secure. Also, there are other services I'm not using, and if they can stop them and close ports, fewer ports open.

If it is shared hosting, maybe he doesn't have root. But yes lsof and even better, netstat -anp | grep -v "^unix" The -anp has netstat give the Process name along with the port Number for All services.
