OpenSSH stops at "SSH2_MSG_KEX_DH_GEX_GROUP"
...oblem with Cygwin OpenSSH, I hope somebody can help me out.
Since we reinstalled our machine we can't connect any external hosts,
but we can connect the gateway server.
The same box is when booted up with linux (Debian unstable) just works fine.
The problem is, that ssh stops at "expecting
SSH2_MSG_KEX_DH_GEX_GROUP" and remains here forever!
I tried to find some answers at google, but I have found nothing.
The strange is that I experience the same problems also with putty.
I paste the verbose output of ssh below.
Thanks, and please if you reply send me a CC.
Regards.

OpenSSH (CVS) performance observations
Hi!
I have experimented a bit with the latest OpenSSH from the CVS archive.
I could realize some connections succesfully, but I experienced performance
problem during the connection phase.
It seems, that the client needs quite some computer time just after
debug: Got SSH2_MSG_KEX_DH_GEX_GROUP.
By inserting test-printouts, I verifyed that the dh_gen_key(dh); call
seems to take that long. On a HP C180 it takes around 8 seconds.
OpenSSH is built without optimization but as far as I could see, the
time is spent in the OpenSSL library (built with maximum optimization).
There are other places...
