"Session terminated" in every 10-20 seconds

[sn-harikrishnaddepalli]

Hello.,

Below is the command triggered :

/opt/tmate-ssh-server/tmate-ssh-server -p 2224 -q 2224 -k /opt/keys -h tmate.example.com

When testing, i am getting "session terminated" in every 10 seconds for new sessions, what is the resolution to avoid seeing "terminated sessions" and avoid causing disruption to remote ssh access ?

Which libssh version do you use?

[indranilvyasFlipp]

I've encountered same issue and I'm using tmate/tmate-ssh-server:prod image available on Dockerhub, I tried using latest image and same issue

[julienduchesne]

I'm getting the same issue with the latest image which uses libssh 0.9.5

[cryptomilk]

I think this should be fixed with libssh 0.9.6
