Your configuration looks reasonable to me. Would you please give us a look at your kernel configuration? Typically a SSH scan of password won't cause the problem you are describing, and this is likely to indicate some other problems, like: - Firewall dynamic rules table filled. - Some critical resources has been exhausted - Maybe some bugs in network adapter driver You may want to try "netstat -m", and ping other nodes when the networking is not working properly. These information would be helpful for tracking down the problem. Also, a /var/run/dmesg.boot would give us some information about your hardware.
