Hello,

I have strange problems with connecting to remote machine running suse
enterprise 9.0 sp3 using ssh

After server is restarted, everything works fine.
Then, after 5-6 days, sshd starts to drop incoming connections.
Server has IP from private network range, i connect to router with
public IP, port 222, which is then forwarded to my server (port 22)
Sometimes, ssh starts to work, but 10 minutes later, again,
connections are refused.

Here is log i've got at client side:

hts-fw:~# ssh xxx.xxx.xxx.xxx -p 222 -vvv
OpenSSH_4.3p2 Debian-9, OpenSSL 0.9.8c 05 Sep 2006
debug1: Reading configuration data /etc/ssh/ssh_config

debug2: ssh_connect: needpriv 0
Connecting to xxx.xxx.xxx.xxx [xxx.xxx.xxx.xxx] port 222.
debug1: Connection established.

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: Connection closed by remote host

Have anyone anything, that can help?
Tahnks in advance
