Thanks Joost, I'll play around with those options. Especially the "-timeout" approach is simple to tryout. Further suggestions about the cause of the problem are still welcome of course. Thanks again, Pieter On Sat, Jun 6, 2009 at 3:03 PM, Joost van der Lugt wrote:

You may want to check:

- timeout setting  in the client - running ssh with higher priority on the server - and/or use *less* ssh commands when the load is high

Dear Bujdosó, thanks for your reply.

_If_ you think that the firewall is responsible for the timeouts you might take a look at your /var/log/firewall

In the firewall log, I have no entries for the machine from which the connections were initiated (and refused to).  How should I interpret this observation?

...

Then you can look at /etc/sysconfig/SuSEfirewall2 config file in the "FW_SERVICES_ACCEPT_EXT" section.

The hitcount/blockseconds identifiers do not occur in this file...

Should I investigate other paths than the firewall?  Any clues?

Thanks a lot for your advice, Pieter
