Description Yanko Kaneti 2018-04-16 08:01:32 UTC

Description of problem:
The exact same sshd config (with PermitTunnel yes)  works with
openssh-7.6p1-7.fc29.x86_64.rpm and doesn't with openssh-7.7p1-2.fc29.x86_64

With two preconfigured tun0 interfaces on both sides and logging in as root:

# ssh <7.7 host>  -w 0:0
...
channel 0: open failed: connect failed: open failed
...



The client version is the same openssh-7.6p1-5.fc27.x86_64

Thanks for the report. Already discussed upstream [1] and fixed in 7.7 branch upstream. I will bring the fixes in soon to Fedora.
