ssh_exchange_identification: Connection closed by remote host

Hi,
I try to co connect to a linux server and get following message:

Code:

me@host:~> ssh -X target -vvv

Now I am trying to figure out what the problem is but I cannot connect to the target server. Is there any other way to connect except using ssh?
Thanx

Looks like something wrong with your keyfile

Code:

debug3: Not a RSA1 key file /users/me/.ssh/id_rsa.

You should check the key files' contents.

The only person who can tell you how to connect is the sys admin.
If its ssh-keys only, looks like you may have to generate a new pair and send the pub key to him out-of-band or he may allow passwd access just long enough to send the new key.

I can connect to other servers so I think the problem is not in the keyfile.
I only know that there has been a distro upgrade on the machine with the target server.
