Typo with dynamically removing port forward in ssh

[Brad Marshall]

When using ssh and managing ssh port forwards with ~C to remove a forward that doesn't exist, the following occurs:

  user@host:~$
  ssh> -KD12345
  Unkown port forwarding.

ie, the mispelling of the work Unknown as 'Unkown'.

This occurs at least on a server running on trusty:

$ dpkg --list | grep openssh
ii openssh-client 1:6.6p1-2ubuntu2 amd64 secure shell (SSH) client, for secure access to remote machines
ii openssh-server 1:6.6p1-2ubuntu2 amd64 secure shell (SSH) server, for secure access from remote machines
ii openssh-sftp-server 1:6.6p1-2ubuntu2 amd64 secure shell (SSH) sftp server module, for SFTP access from remote machines

Please let me know if you need any more information.

Thanks for taking your time to report this issue and help making Ubuntu better.

I can confirm that this typo is still present in openssh 1:7.4p1-6 on Ubuntu Zesty, more specifically in the file clientloop.c. It looks like this issue isn't introduced by packaging in Debian/Ubuntu, but seems to be in openssh itself. I wonder if a fix should be forwarded there.

As mentioned in the upstream bug report, this issue has been fixed in OpenSSH, and the fix is included in the openssh package (1:7.5p1-10) in Ubuntu 17.10 and later.
