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 > ssh -vvvv XXX@tangserver OpenSSH_7.8p1 Debian-1, OpenSSL 1.0.2o 27 Mar 2018 debug1: Reading configuration data
