Unix socket forwarding stopped working

[Arne Brants]

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?
