problem. I can telnet to most address however there are those I can not telnet to. I know the systems are up because I can reach them if I logon to another system and telnet to them. I have tryed both telneting to the number and the name with no luck. I have been running as a resolver but have tryed running the system with a /etc/hosts file. I have called all the people I can and have RTFM until my eyes hurt. If you have a suggestion or know of someone else with this problem please let me know. -- ================================================================================ = Sgt Richard J.

Can you telnet from them to you? How 'bout traceroute? If the remote systems can't reach your system for some reason (bad routing, bad resolving, etc.), then telnet won't work.

Cisco routers have the capablity to have acess and deny lists your net address maybe denied. Other than that I have no idea. NJC
