Exclamation Problem with ssh

Hi All,

I get the following error message when i try to ssh to a node

Code:
ssh_exchange_identification: Connection closed by remote host
this is the output when i run in verbose mode

Code:
Sun_SSH_1.1, SSH protocols 1.5/2.0, OpenSSL 0x0090704f
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Rhosts Authentication disabled, originating port will not be trusted.
debug1: ssh_connect: needpriv 0
debug1: Connecting to crmsam [10.148.123.140] port 22.
debug1: Connection established.
debug1: identity file /home/rkadm/.ssh/identity type -1
debug1: identity file /home/rkadm/.ssh/id_rsa type 1
debug1: identity file /home/rkadm/.ssh/id_dsa type -1
ssh_exchange_identification: Connection closed by remote host
debug1: Calling cleanup 0x8070c6c(0x0)
Keys are shared with the two hosts. It was working fine previously and all of a sudden the error message.

Please suggest.

Check the files in /etc : hosts.allow, hosts.deny, comment what you have there and test. Restart the sshd and check the /var/log/messages or other respective log file for obvious errors. Check your /etc/ssh/sshd_config as well.
