Suppressing ssh banner from OpenSSH client

Solution 1:

AFAIK, "ssh -q" or "LogLevel QUIET" in ~/.ssh/config are the "traditional" ways to silence the banner. So you already have a "better" compromise with "LogLevel ERROR".

A more specific solutions would be to use a custom patched version of the ssh client, if this is an option.

Solution 2:

You can also use:

Banner none

on

/etc/ssh/sshd_config
