Package: openssh-client
Version: 1:7.4p1-10+deb9u4
Severity: important
Tags: upstream
Dear Maintainer,
I want to report an issue that appears after installation of latest version of
openssh-client (1:7.8p1-1)
When I try to push source code on our enterprise gitlab repository I'm
encountering a broken pipe error.
I tryed to investigate more deeply and when I try to connect to my home server
I got the same issue. You can see log of ssh below.
When I try to connect to localhost it works perfectly.
My best clue is if there is a lot of chars retrieved after connection, the
connection hangs. On my home server I have linuxlogo which dumps an ascii art
logo.
I also tryed to stop ssh server and autossh but it changed nothing.
Reverting back to old openssh-client solved the problem (1:7.4p1-10+deb9u4)
Thank you
