Re: getting ssh1 support

Sorry, I am a bit lost here.

 From what I can tell, there is a vulnerability with SSH1. It is not
advised.

The problem I have is that I need certian applications that use sftp
such as dreamweaver do not support ssh2. And thus far I have been
relying on ftp which I would think is 'less secure' than a vulnerability
with SSH1. Am I wrong? I have been trying to wait the stink eye contest
out with macromedia but as far as I can tell..... This is never going to
happen on their end.

So I try to generate a key

ssh-keygen -t rsa1 -f /etc/ssh/ssh_host_key

then edit /etc/ssh/sshd_config

Protocol 2,1

try to restart ssh and I get;
Disabling protocol version 1. Could not load host key
Restarting OpenBSD Secure Shell server: sshdDisabling protocol version
1. Could not load host key

Can somebody point me in the right direction? Also, would the SSH1
vulnerability be cut down if I only allow 1 non-root user SSH access via
AllowedUsers?

Did you add this?

HostKey /etc/ssh/ssh_host_key

to /etc/ssh/sshd_config?

Incidentally, you can tunnel your connection through regular SSH2.

ssh -f -N -L 22:localhost:22 user@remote

Then if you tell your app that the ssh server is localhost, your
traffic will be in an SSH2 tunnel.  You could do the same for
regular FTP through a tunnel.
