Hi Chuck - >I notice that on the 2 servers I do hit for email, they both show :pop3 so >what is the :1214 at the end of the rr address ? If you use the -n switch with netstat, it will not convert port number to their names for the common ports. It also will not attempt to convert IP addresses to host/domain names. pop3 is port 110. All of the standard ports for incoming connections are below 1024. Some common ones are: 20 FTP data 21 FPT control 22 SSH 23 Telnet 25 SMTP 80 HTTP 110 POP3 443 HTTPS Specialized applications may use ports of 1024 and above for incoming connections. For standard applications the outgoing port number is an incrementing number starting at 1024 and working up to 65535. >ProTo Local Address Foreign Address State > >TCP gr30:2342 >clt74-35-022.carolina.rr.com:1214 ESTABLISHED > >the local address is my PC's name. > >is the :2342 a Port # - if so, what is it for ? >is the :1214 a Port # - if so, what is it for ? The main question here is, did your PC establish the connection or did the rr.com system? If your PC established the connection, then you need to think about what you are running. You may have "spyware" on your PC "phoning home". If rr.com established the connection, then there had to be some kind of program on your PC listening on port 2342, otherwise the connection request would have been rejected. You may have a "trojan" program on your PC which someone could use to execure remote commands or do other naughty things. You may want to install a desktop firewall. Not only can it prevent unauthorized incoming connections, it also can prevent unauthorized outgoing connections if configured to do so.
