Hi, I'm using openssh to forward a remote unix socket to my local server. This has been working just fine until recently, but since a few days it is no longer working and I get error messages in the console when accessing the local socket The command I use: ssh -C -f -N -L/local/socket:/remote/socket user at remote-system Error on connecting to local socket: channel 1: open failed: unknown channel type: Local system: Debian Jessie Kernel 3.16.0.4 OpenSSH_6.7p1 Debian-5+deb8u3, OpenSSL 1.0.1t 3 May 2016 Remote system: Debian Jessie Kernel 4.7.0-0 OpenSSH_6.7p1 Debian-5+deb8u3, OpenSSL 1.0.2j 3 May 2016 Would this be an SSH or SSL issue, or has something broken between the two packages?
