Here the debug. It seems OpenSSH has the same issue.

With following in ssh_config for my host, it's working:

Okay. So i cannot change the server (update or settings). I will try to force 'diffie-hellman-group14-sha1'. Thanks!

I have a request. Could you add the perl binding in the listing ? Or is not enough finished for that ?

Thanks! I test tomorrow with your patch on libssh. I give you a feedback if it solved or not.

You can test it if you have a rhel/centos 7. Need to install rpm:

I didn't test with 'MaxSession 0'. I let the default value. I have done a new test with libssh 0.9.0. I tried to open 12 channels at the same time. Now it hangs on 'ssh_channel_request_exec'.
I should have an error before when i tries to open a session with 'ssh_channel_open_session' no ?
