how to uninstall ssh?

[Wang Li]

Dear Sir:

I have installed ssh2.3.0 server. But because of the license concern,only
2 clinets can communicate with my server at the same time. So I want to
uninstall the ssh2.3.0 and install ssh1. But I don't know how to uninstall
it. Can I install ssh1 without uninstalling ssh2? If I have to uninstall,
how can I? I don't know the directories where the ssh2 are in, so i can't
derectly delete it. Would you please help me?
