Are you compiling with any optimizations? I had a problem similar to this in that ssh, ftp, apache were running, and I could connect on my internal network....but connections from the outside (like me trying to connect to it from work) would either make it seem the machine was "locked down". you could ping and see that it was alive, but you couldn't get in through SSH or anything else. I traced it down to a compile I did with kernal optimizations (-02), so I turned that off, rebuilt the kernal, rebooted and all was fine. - Daryl Chance | And which parallel universe did ValueData, LLC | YOU crawl out of?
