sshd, remote deskop, all inaccessible?

remenic · #1 11th April 2011, 03:14 PM

Heya, I've configured remote desktop and sshd, but I'm unable to log in from any other machine. Connecting to localhost (from the same machine) works fine.

I've checked /etc/hosts.allow and /etc/hosts.deny but both didn't contain any rules. I added ALL: ALL to hosts.allow, but still no luck

As far as I can tell, the firewall doesn't contain any rules to block incoming connections either.

Any ideas?

Is your router configured properly? Does it forward the needed ports to your computer?

I was trying to access my machine from another machine in the LAN. Both machines are connected via a switch. Both are in same IP range (192.168.1.0/24).

In your sshd_config file, did you add the AllowUsers line?

I managed to fix the problem!! But AllowUsers wasn't the problem. The problem was me

I decided to check with wireshark to see what was going on, and I noticed that the machine was responding with ICMP "administratively prohibited". Prior to asking for help here, I had checked with iptables -L but didn't find anything out of the ordinary.

After I disabled the firewall with system-config-firewall, it worked. Will try to figure out how to enable firewall while allowing sshd (it was checked, so I'm guessing it *should* have worked). Most important right now, is that I can log in remotely :-)

Thanks to the both of you who tried to help!
