Hi,
I understand that we can disable SSH Protocol
version
1 in sshd_config file by adding the line "Protocol
2".
This merely rejects incoming ssh session using
Version
1.
If I add the line "Protocol 2" in sshd_config of
server1 and "ssh -1 user@server1" from a remote
server, then I got the response "Protocol major
versions differ: 1 vs. 2". This is expected as
incoming ssh session using version 1 is rejected by
the "Protocol 2" line in sshd_config of server1.
However, when I tried to disable outgoing ssh
session
from using Version 1 by adding the line "Protocol
2"
in ssh_config file, it did not work.
Could you give a little detail on "it did not work"?
For outgoing ssh session, I added the line "Protocol
2" in the ssh_config file of server1 trying to disable
ssh session using version 1 from sending out server1.
From the server1, I tried "ssh -1 user@hostname" to
force it to ssh to a remote server hostname using
version 1. The ssh session proceeded as normal with
version 1. Hence, I could not use the same way to
configure ssh_config to disable outgoing ssh session
using version 1.
Is there any way
to disable outgoing ssh session from using Version
1?
-2 on command line forces version 2 only.
I want to disable version 1 by configuration instead
of using command line option.
-v may also be of use to do some debugging (try
-vvv)
