I agree, I have been having to disable it manually on all the machines I
administrate. I have even found putty using ssh1 by default. So this just isn't
a case of when people use ssh1 on purpose.
Comment 2 Mark J. Cox 2003-06-02 07:48:46 EDT
Whilst protocol version 1 has some 'known security issues' in general these did
not affect OpenSSH.  For example looking at
http://www.f-secure.com/support/technical/ssh/ssh1_vulnerabilities.shtml each of
these issues does not affect OpenSSH, and http://www.openssh.com/goals.html
gives you some more details.

We should consider this again as most clients now support ssh v2.
