This is quite normal since (from the OpenSSL documentation) Solaris
doesn't have a /dev/random, generating keys takes a long time. It's
even worse with old Sparc hardware: everytime you login using ssh
(which is what CVS is doing) you can see the CPU usage go to 100%.
BTW the documentation that comes with OpenSSL (and also de Sun Web
site) recomends installing a /dev/random from one or two sources. It
does help a little.

^^^^^^^^^
What's this doing here? You only need to log-in if you're using
pserver.

Try by setting CVSROOT=":ext:myuser@remotebox:/var/cvsroot" and then
just do the "cvs co project".
I don't know why the sample you show hangs, but it has nothing to do
with ssh, it probably is something wrong with cvs. Better test with
the :ext: protocol and see if it still hangs.
