Hi,

Maybe this is an idea:

1. the output

------------- [gkondal at Cobra gkondal]$ Address 127.0.0.1 maps to gkondal-lt, but this does not map back to the address - POSSIBLE BREAKIN ATTEMPT! -------------------

states, that you try to login from localhost (127.0.0.1), which can be mapped to gkondal-lt. Okay. I guess gkondal-lt also has a "real"-IP-address, hasn't it? Try to use this one - I'm afraid I don't know where localhost comes from in your settings. I think it's quite common that a dns-name isn't resolved to 127.0.0.1 but to the "real" IP-address.

If you have set up the host name as another alias for 127.0.0.1 in the hosts file and the hosts file is the first or only authority for domain name lookup, you would get this result.

2. To test whether a request reaches the server or the firewall or something in between you can use a IP-sniffer. You can set a filter for the Perforce-Server-Port (1666 I guess).

If that fails, you can set up a shell script as an inetd service on that TCP port (shutting down the Perforce server, of course, to make the port available). All it has to do is cat to a file. The only problem you will have is that unless the Perforce protocol ends requests with EOF (generally ctrl-D), the process will hang because cat doesn't know to end. It's a good quick way, however, to check for connectivity.
