Troubles connecting with ssh

Asked by Miles Hamilton on 2011-11-30

Hi, I'm new to Ubuntu, just started using it a few days ago and have really enjoyed it thus far. One issue I am running into is when I try to ssh to another device that I own it disconnects. I am using the right password and account but it disconnects. Any help would be greatly appreciated. The session is as follows:

miles@ubuntu:~$ ssh 173.157.110.110 -l login -p 222
The authenticity of host '[173.157.110.110]:222 ([173.157.110.110]:222)' can't be established.
RSA key fingerprint is 48:77:9c:ca:be:78:50:60:6d:2d:d0:83:bf:56:c9:32.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '[173.157.110.110]:222' (RSA) to the list of known hosts.
login@173.157.110.110's password:
Connection to 173.157.110.110 closed.

Hopefully none of this is too identifying. The other device is my Palm Pixi if that helps. I enabled ssh from the Pixi side and I'm pretty sure I did everything else right. Did I maybe miss something? I have been following the tutorial at http://palmpre-hacks.com/palm-pre-hacks/how-to-set-up-google-gps-tracking-on-your-palm-pre/ to the T

On the client run:

mv ~/.ssh ~/.ssh_old

Then try connecting, is it ok?

It didn't change anything, I am wondering if there is maybe a setting on the server side that could be preventing access? What would be some common things to check?

There doesn't appear to be anything in this log relative to the ssh session, but I am by no means an expert. I ran another attempt and the only thing in the log during the time I am on is this:

I attempted to connect around 14:16 and again around 14:20 or so. does any of this make sense? For some reason I get the impression that my laptop, which is what I am using to access my phone, needs to be on some kind of list. The way it sounds to me is that when a request comes in from an external location, the phone runs the info from the external computer against a list and if it isn't in the list it closes the connection. Would this make sense? If it does, what type of file and location should I look for for this list? (It doesn't say much about in the config file)
