Re: ssh2 & ssh1 compatability problem in inetd mode.

[Peter J. DiCostanzo Jr. - ComPath Inc.]

The reason for this is simple, tho I've asked in this mailing list, irc,
various web boards... Everyone says this is the way it should be...  in
the PRE 2.4.0 days ... when you connect to port 22 of a box running ssh in
inetd mode OR standalone mode.. you would receive the following output:

SSH-1.99-2.4.0 SSH Secure Shell (non-commercial)

except with correct version numbers of course... NOW if you telnet
localhost 22, you will see the following:

sshd2: SSH Secure Shell 2.4.0 (non-commercial version) on 
i686-pc-linux-gnu
SSH-1.99-2.4.0 SSH Secure Shell (non-commercial)

TWO lines of output.. ssh version one is expecting the second line only,
which identifies version number... ever since i have installed ssh version
2 .. and specified ssh1 compatability (at compile time) AND in the conf
file no ssh1 clients have been able to connect.. =(

However, the few people that have responded insisted that this is
correct according to the notes on the new protocol. This doesnt make
sense to me because this makes it non-backward compatable..  Anywhoo try
it out.... 

I realize this isn't a solution.. but at least you know what the problem
is.
