Hi Everyone,
I am having problems SSHing from a client to the server. When the server is restarted, everything works fine. Few days/weeks (this happens at irregular intervals) after restarting, the problem (i.e.,not able to SSH) appears again.

note:
-------
I am able to ping the server and get all the replies even when it is not SSH'able. The server which acts as a gateway keeps routing the traffic from the internal network irrespective of the SSH issue.

When I issued an SSH command with the -vvv option, it displays the following:

[root@devBox ~]# ssh -v <ipaddress>
OpenSSH_4.2p1, OpenSSL 0.9.7f 22 Mar 2005
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug1: Connecting to  <ipaddress> [<ipaddress>] port 22.
debug1: Connection established.
debug1: permanently_set_uid: 0/0
debug1: identity file /root/.ssh/identity type -1
debug1: identity file /root/.ssh/id_rsa type -1
debug1: identity file /root/.ssh/id_dsa type -1
ssh_exchange_identification: read: Connection reset by peer

The sshd server is breaking the connection, but there is no indication why on the client side. Server logs, and debugging sshd itself, could be more useful.
