Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I'm very new to owning a dedicated server. I'm learning and was configuring one I bought with OVH. I was configuring what I thought was other SHH users.

It was a sshd_config. I appended this to the very bottom of the file:

Port 24
PermitRootLogin no
AllowUsers zax

After that I logged off putty and WinSCP and attempted to log back into the servver. It was giving me denied access.

I know OVH is a budget provider, and I attempted to ask them support and they replied as the only option is to re-install the OS.

I'm totally fine with, because I didn't do much with the OS but I'd rather still want to make sure if theres any other option to get back into the OS. So my question is: Is there any other way to get back into the OS?

If it is the only option, what do I input into the following options to re-install an OS?

It's a 64-bit Ubuntu Server.

Did you restart sshd? If not, ssh is going to accept connections on your previous port. –  Pants Feb 3 '13 at 13:22
    
If you restarted sshd, did you tell WinSCP/Putty to use port 24 in the first place? –  SvW Feb 3 '13 at 13:44
    
Is port 24 blocked in a firewall? –  Keith Stokes Feb 3 '13 at 13:57
    
Yes, I restarted sshd. And I tried port 22-24 –  devs Feb 3 '13 at 13:58

OVH offers a Serial-over-LAN option you can use to login to your dedicated server as if you had a keyboard and monitor directly connected to it. Since this login does not go through SSH, you won't be constrained by the options you set.
