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 11:48:46 UTC
Whilst protocol version 1 has some 'known security issues' in general these did
not affect OpenSSH.  For example looking at each of
these issues does not affect OpenSSH, and
gives you some more details.

Comment 3 Tomas Mraz 2005-02-04 14:14:56 UTC
We should consider this again as most clients now support ssh v2.
