This simply means telnet was unable to connect to the chess server. It could be because ICS wasn't running, or the system itself may have crashed. You can check for the latter by trying "ping lark.utah.edu" or perhaps "/usr/etc/ping lark.utah.edu". Some pings will even tell you how long it takes for a packet (a character, f'rinstance) to travel to lark and back to you. I've run telnet accessable servers before, and "Connection refused" leads people to believe that things may be working, but for some reason they're not being permitted to access. This is almost never the case. If you're C programming, and use errno.h in a client, it will print this message. I'd recommend changing it. Sometimes, you may get "network unreachable", which means that for the moment, the Internet routers haven't figured a way to connect you there. It's usually caused by a network outage somewhere. Sometimes the routers find an alternate way (usually in about 15 mins), and sometimes the problem can't be bypassed.

The connection refused means that either "no one is listening on the port you are trying to connect to (TCP/IP port, not a phone line port) or that someone is listening, but is not willing to accept another connection for one of many reasons. Common reasons include network being shut down, particular service you want is at some max load level and new users are not allowed, etc. It does not mean the system (unix) is "down" because it can't refuse a connection if it is not alive enough to "refuse" it. -- !Robert Hyatt Computer and Information Sciences ! !hy...@cis.uab.edu University of Alabama at Birmingham !
