SSH closes connection before login

Im Very Very new to LINUX and Networking. I have some basic understandings of networking.

here is the debugging info

Whyen i try to connect from inside the LAN I get this:

$ ssh -vv
OpenSSH_3.9p1, OpenSSL 0.9.7e 25 Oct 2004
debug2: ssh_connect: needpriv 0
debug1: Connecting to [] port 22
debug1: Connection established.
debug1: identity file /home/Administrator/.ssh/identity type -
debug1: identity file /home/Administrator/.ssh/id_rsa type -1
debug1: identity file /home/Administrator/.ssh/id_dsa type -1
ssh_exchange_identification: Connection closed by remote host

Im not sure how to go about troubleshooting. I freshly installed Mandrake 10.1

There is a DNS and a VPN on the network along with other comps.

When i try to connect from outside i get the host is unknown.

If you can help ThanK you SO MUCH

identity file /home/Administrator/.ssh/id_dsa type -1
probably your host accepts only type -2 DSA

Does ssh work If you are sitting at In other words, will it connect to itself? If not, it will narrow the problem, if so, you can check on the protocol.

might be a reverse lookup issue also - check that VerifyReverseMapping is set to 'no', or if it's set to 'yes', that a reverse lookup on your LAN ip returns the correct hostname.
