https://bugzilla.mindrot.org/show_bug.cgi?id=3632

            Bug ID: 3632
           Summary: ssh should suppress output in stout and stdout when
                    calling third party binaries
           Product: Portable OpenSSH
           Version: 9.4p1
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: ssh
          Assignee: unassigned-bugs at mindrot.org
          Reporter: dbelyavs at redhat.com

ssh -q to an unknown host should be a silent failure but with ipa/idm
installed a program called sss_ssh_knownhostsproxy writes to stderr.

To reproduce it, you need to have SSSD client enrolled to a FreeIPA
server and run "ssh -q thishostdoesnotexist ls"

The FreeIPA project provides a demo server that can be used for this
purpose. The client only needs to follow the steps at
https://www.freeipa.org/page/Demo to set up the environment

--- Comment #1 from Damien Miller <djm at mindrot.org> ---
There's no need for ssh to do this because it's trivial for the user to
do this in the ProxyCommand itself, e.g.

ProxyCommand "somecommand 2>/dev/null"

Moreover, having ssh unilaterally discard stderr is not desirable as
the user may want diagnostics from ProxyCommand.
