Bug ID: 3088
Summary: sys_tun_open: failed to open tunnel control interface:
No such device
Product: Portable OpenSSH
Version: 8.0p1
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: sshd
Assignee: [email protected]
Reporter: [email protected]
I've tried this on four different servers running versions from 7 to
8.0p1-3. All the servers were running linux. I tried it on x86_64, x86,
and MIPS and get the same error each time. This is the command line
that I am using:
$ sudo ssh -v -w 1:1 -o Tunnel=ethernet [email protected]
...
debug1: Requesting tun unit 1 in mode 1
debug1: sys_tun_open: failed to open tunnel control interface: No such
device
Tunnel device open failed.
Could not request tunnel forwarding.
...
It logs me in and brings me to the prompt, but tap1 doesn't exist on
the remote or local server.
