View Full Version : [SOLVED] SSH: No connection

Hi everybody,

I try to connect from my laptop to my server on my home network thru SSH.
Both computers are running Ubuntu 10.04 64-bit.

The server has SSH installed and running.

When I issue the ssh -v command I get this:

OpenSSH_5.3p1 Debian-3ubuntu4, OpenSSL 0.9.8k 25 Mar 2009
debug1: Reading configuration data /etc/ssh/ssh_config

Question #1: The <user> on the client does not exist on the server. Is this OK ?
If it is, what <username> should my ssh command use ?

Question #2: ssh seems to try to connect using my DSA private key. I want it to try to connect using my RSA private key. How do I do this ?

Question #3: What else should I do to make it work ?

And no reply so far, also ! Any ideas ?!

Strike Question #1 ! In view of what I read in the meantime, the username on the server is the one which matters, since I actually connect as that user on the server.

OK, so it works now - dunno exactly why :P.

I did the following:

I recopied the public key to the Host and cat'ed it in authorized_keys (by creating an empty file and then updating it).

I changed the authorized_keys2 filename back to authorized_keys (as it was in the beginning) and made sure that its correctly referred to in sshd_config. (I had changed the name because of some wiseguy's post on the Net.)

I think that's all. Now its working. :guitar:

Cheers mates,
