we are using iptables, but as far as I know there is no timeout set on
our iptables.
this is happening sporadically.
I thought that if it is related to network we will receive some kind of
connection error and not freezing screen.
Thanks for help

Is there a firewall between your client and the server (that kills the
session after inactivity)? Try the keep alive option.

ssh terminal froze once in a while
I've had problems with xterm locking up.
It seems related to using ascii colors.
At first I thought it was an ssh problem because it mostly happened on
remote machines, but then it started happening locally too.

I suffer this kind of problem using putty for long time now. The
terminal freeze for about
45s to 3min. Other putty session are still working.
I got this for 2 or 3 years now, on about all RedHat distribution and
clone from RH Linux 8.0
and on a lot of different network infrastructure, with different hardware.
The most common part is WinXP and putty, but in all version and service pack.

Ops, I'm thinking about of a lack of entropy!
Maybe the ssh session is renewing the connection keys and need some
entropy to generate them.
Maybe the use of /dev/urandom instead of /dev/random ....

Had the same/similar problem. Our home dirs are nfs mounted from a linux
box & if I explicitly set the nfs mount options in fstab instead of
using the catchall "default" , the problem seems to go away. Workign
locally on the client on the nfs home dir was OK, just that an ssh
session to another box ( and same nfs home dir ) would occasionally hang
after time.
Never found any complaints in any log files - discovered my "cure" by
accident really.

Hi just as a question is anyone actually restarting sshd on the machine
that you see this? Because often the SSH rule is set up for new
connections, and I have seen existing ssh drop because of this.
Have a nice day

This happens to me when I SSH from a Mandriva box to my CentOS
server. It does not happen when I SSH to another Mandriva box,
so it's a CentOS thang.
I turned on the TCP keep alive option in the SSH configuration,
but it still happens. This is exceptionally annoying.

I've been using Putty in various versions for years multiple times a day and
from various locations and thru various connection methods. I don't see any
difference when connecting to CentOS or Suse or FreeBSD, it's just fine and
stays fine over hours or days. Also no problems with "inter-linux" connections
(which I do on the command-line, not with a GUI client).
Especially in the case of Windows I'd suspect an "overzealous" personal
firewall or other security product causing your problems. It might also depend
on the NAT or firewall configuration.
