Solaris 9 ssh

I'm having some difficulty when connecting to a machine with the ssh.com
ssh2 server.  The ReKeyIntervalSeconds is the problem.  Sun's ssh is based
on OpenSSH, but doesn't identify itself as OpenSSH so my session hangs
after an hour.  Is there a solution other for this other than telling the
admin with the commercial ssh2 server to reconfigure with the
RekeyIntervalSeconds 0.  It use to be a problem with NetBsd, but since it
identifies itself as OpenSSH on connection the rekey aren't forced.

Thank,
Lisa
