openssh unix dev - Feb 2008 - ssh_exchange_identification: Connection closed by remote host

Hi,
   
  I'm getting this error when I ssh to the servers.
  ssh_exchange_identification: Connection closed by remote host
   
  I added /etc/hosts.allow and it actually worked once and if I tried again I
get the same error.
  OpenSSH_3.6.1p1, SSH protocols 1.5/2.0, OpenSSL 0x0090702f
debug1: Reading configuration data /usr/local/etc/ssh_config
debug1: Rhosts Authentication disabled, originating port will not be trusted.
debug2: ssh_connect: needpriv 0
debug1: Connection established.
debug1: identity file /username/.ssh/identity type -1
debug1: identity file /username/.ssh/id_rsa type -1
debug1: identity file /username/.ssh/id_dsa type -1
ssh_exchange_identification: Connection closed by remote host
debug1: Calling cleanup 0x2cc60(0x0)

  I look forward to your response.
  Thanks

You did not mention whether you added by name or by IP.
Every time I've seen this error it has been a DNS problem. And I only
see this on systems that are in hosts.allow by name.

In my experience this error is typically really a network problem. Try
doing manual telnet to port 22 on the server. This should show you the
server ssh version (i.e. the initial identification) like
"SSH-2.0-OpenSSH_4.3p2 Debian-7ubuntu1"

If it does not then there is your problem.

What did you add to /etc/hosts.allow, and what do your logs say?

Greetings
