ssh_exchange_identification: Connection closed by remote host

[chkbrian]

The problem was occurred due to incorrect setting of hosts.allow for tcpwrapper. We have two interface with different Ip address. Only one interface/ ip address was granted access right via hosts.allow. 

However, always while we want to ssh to hkmauat, the interface/ip address not in hosts.allow was used. So the access was not successful. If the granted interface/ip address was in used, the access was okay. So, the problem is not occurred sometime.

Now, we have modify the hosts.allow in hkmauat to include two interface/ip address and the problem is resolved.

Thanks.

You should specify your platform and OpenSSH version, but this is almost
certainly due to tcpwrappers configuration.

Add the following line to hosts.allow:
sshd: ALL

It may be in /etc or /usr/local/etc.

Alternatively you could rebuild sshd without "--with-tcp-wrappers".
