I can think of two possibilities. One is a firewall rule. The other is an ssh setting, something along the lines of denying access to root, even with a correct password. I forget the exact syntax, but IIRC it is self-explanatory when you see it. Try grepping the ssh config file(s) for "root". Step one: Try logging in as someone other than root. If it works, then check the ssh config, as above. (Heck, check it anyway). Step two: Review your firewall logs to see if anything is getting blocked to/from either machine during an attempt. If your firewall is not logging, you may be able to figure it out with the -L -n flags on the firewall command. (I know it works with iptables, not sure about ipchains). What I sometimes do is: iptables -L -v -n >x.1 [do whatever I am testing, then] iptables -L -v -n >x.2 diff x.1 x.2 Just be aware that anything else that comes along during the testing will show up, too. Step three: Relax, have a beer and a hot dog, watch some fireworks, and tackle it after the Holiday? (just kidding... I don't even know if you are in the U.S.) ;) Happy Fourth of July to you all, anyway.
