- Subject: openssh delay (5secs) to windows XP cygwin box
I am running the current version of cygwin on a windows XP box (a recent
laptop), I installed openssh and I setup'ed password less authentication
(I use also privilege separation)
time ssh laptop date returns in 6seconds whereas the openssh webpage
suggest a modest hardware should do the same within 1 sec.
My problem is the delay to connect to the box. On the openssh webpage,
it is mentionned that delays above 10secs come from DNS/resolution
problems. The delay I have is 6secs and does not come from DNS issues (I
removed DNS from the way by two means. First I have put all information
into /etc/hosts and second I have UseDNS set to no in sshd_config (and I
did stop/start sshd via net stop/start sshd))
I tried to run ssh -vvv on the client side (debian linux) to see where
the process is stuck.
I also tried to run sshd in debug mode. Nothing interesting at least for
me and google.
I also tried to do the same with localhost from the windows box to
itself. This also takes 5secs. The only interesting thing I found is
that when I unplug my laptop from the network everything becomes smooth:
(laptop plugged into the corporate network)
time ssh localhost date

(laptop unplugged from the network)
Can anybody tell me if there are some tricks to play with Windows around
thanks in advance for any help.
