I have a web/mail server running FC5/Apache/Qmail. Everything was running fine yesterday and then when I tried to get my mail this morning I get a connection timeout error when trying to pull up a webpage.

It also looks like it is blocking all the other ports as well. I have tried to telnet to various port and get no response from the server. I have tired it on the local machine (the one that has problems) and I can connect to the ports.

I have ran the system-config-securitylevel-tui and disable the firewall for the time being to see if that was it and it didn't seem to solve the problem. I also have selinux disabled.

I thought maybe it was the smoothwall I have in front of the boxes was having an issue however it seems to be forwarding all other ports to other machines just fine, so it seems to be something with that box.

I have also looked in the logs and don't see anything out of the ordinary.

I'm stumped, not sure where to go from here.

Any help would be great.

Thanks
Troy

could be a network cable problem.

I can ssh to the box from another box inside my network. I cannot access it via ssh directly though.

It appears that it my be something that was upgrade before the restart, but I upgraded about 200 things since this was a new install of FC5 and I'm not sure what would cause all ports to be blocked.

Are you saying that you can run 'ssh brokenpc' and that works but 'ssh localhos' does not work?

I have 2 servers: testserv & webserv
The broken server is webserv

I cannot use say Putty (ssh app) to go directly to webserv however I can us Putty login to the testserv then do a ssh to the webserv.

It looks like a problem with either your firewall or it could be your /etc/hosts.allow file. What does /etc/hosts.allow say? It could be that your firewall only allows yout to SSH to the testserver.

I think something go messed in my router so I ran the following command and it fixed it.

/sbin/route add -net 0.0.0.0 gw 192.168.0.1 eth0
