My friend has sent up a gateway computer for my small business. The gateway runs a Shorewall firewall. My company also runs a mail server and a samba file server. I used to be able to putty or telnet into the gateway to check on log files and firewall log files, but lately I cannot putty or telnet into the gateway machine. The SSH is down is the warning message that i get from "big brother".
You would have to check the logs to find the reason. Since you can't access the logs over SSH you unfortunately would have to be at the console if you can't transfer them in any other way.
I cannot putty or telnet into da server frm any other computer. When i sit at da gateway computer things just flash down da screen and i cannot access an of the shells. a restart of the gateway server fixes da promblem but in a few days the same thing happens. "cannot putty or telnet and cannot access a shell frm da actual server"
The machine is connected to a DSL modem that connects to the internet. During lunch time the DSL modem went down and the isdn backup modem kicked in.... just not my day today!

I would check on the version of ssh, shorewall and iptables and see if updates exist and check to see if any thing like this happens with any like exploits.
