Package: libssh-4
Version: 0.9.3-2
Severity: important
Tags: upstream
Dear Maintainer,
* What led up to the situation?
I have a custom ssh_config [1] that defines a not default ssh port.
When using tmate. Tmate cannot connect to ssh.tmate.io because libssh
version 9 I think doesn't parse correctly the ssh_config, it tries to use
the non default port instead of the port defined for *.io. In [2] I explain
how to reproduce the problem.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Comment the ssh port option in ~/.ssh/config
Downgrade libssh to last stable version
* What was the outcome of this action?
Tmate worked
* What outcome did you expect instead?
That tmate using libssh-4 V9 worked
