Sorry I didn't mention. I do have a /dev/random device intalled. It's for a
third party, but I am sure you know it sinsce it's the only popular one out
there. I can prolly find the URL if you want.

It could be this though, since I don't experience the same delay when I go
to a linuxbox. I don't get why though. This sun box does have /dev/random.
Maybe openssl is not using it?

Yeah, sorry. That shouldn't be there. I must've gotten it from above. I was
testing by using ssh as a tunnel and using pserver and that worked without
any hang in the end.

Well, that's what I did with ssh. CVS_RSH is set to ssh. I am not sure if
that :ext: is needed.
Now that I updated 2.9 to 3.1, issue seems to be gone.
