ssh_config Ciphers changes do not work

4n0nx

I changed "Ciphers" in /etc/ssh/ssh_config on my Debian 7 server.

However, no matter what I choose, when I connect from my Ubuntu 14.04 PC, ssh -vv always outputs aes128-ctr. I have restarted SSH and rebooted the server. When I specify the cipher with ssh it works (e.g. ssh -c aes256-ctr).

I also changed "KexAlgorithms" and "MACs", with no effect as well.

What am I doing wrong? How do I disable weak ciphers on the server?

Thanks

Try editing sshd_config (which actually affects the SSH server, and not the SSH client).

Thanks. Now it works.
