Cisco vs. 6.9
After upgrading a Linux system from OpenSSH 6.7 to 6.9, Cisco
switches/routers can no longer scp config files to/from the system. The
last debug entry before the Cisco device closes the connection is "debug1:
server_input_channel_open: confirm session". The next line is "Connection
closed by x.x.x.x". Anyone else seen this or know of a fix? The Cisco
device gives

Client fails kex after c38ea634893a1975dbbec798fb968c9488013f4a
I have a Putty variant that works well with openSSH up until 7.4. After
git bisecting I found that after the application of
c38ea634893a1975dbbec798fb968c9488013f4a the client fails with host key
mismatch. The commit in question appears to remove vestiges of ssh-1

commit would lead to the symptoms. I have been through the

I.e.,
It's asking for Password, not accepting pubkey
AND
when given the password (which is correct), and the GA VerificationCode, it
simply repeats the credentials request.
