SSH: Setting up a server to the outside world - Ubuntu 12.04
 
I have an SSH server running on my new linux box. It works within the network just fine, but if I try to connect to it from outside of the network, I get this:
Code:
$ ssh [my ip]

I'm kind of a newbie to linux (been using Ubuntu since Febuary), so I don't really know what's going on, or how to fix it. Any help is appreciated.

What does /var/log/auth say about the attempted login (server log)?

TechHunter16 07-06-2012 08:51 PM
It says I don't actually HAVE a /var/log/auth file.

sag47 07-06-2012 09:09 PM
What distro is the server running? If it's RHEL based then the other place is likely /var/log/secure.

TechHunter16 07-06-2012 09:10 PM
I'm running Ubuntu 12.04 on both the server and client, so they're Debian-based.

sag47 07-06-2012 09:16 PM
Ah I just checked on my Ubuntu 12.04 and the log is /var/log/auth.log. Please, do some additional investigating on something like that. You would have figured it out with ls in /var/log/. At any rate please pastebinit or post the chunk where you're attempting to auth.

Tip, you can
Code:
tail -f /var/log/auth.log
while you attempt to ssh and see the logging as it happens. This is sometimes very useful.

Hmm... Okay, well, now it seems to work. Sorry for your trouble.
