How to overcome "tun0: Disabled Privacy Extensions"?
I need to open a tunnel between two machine of mine where I hold root access.
I've read this document: https:/
I've set up a key pair between the two machine's root account (~root/.ssh), I've changed the sshd_config with the following
parameters:
PermitTunnel yes
PermitRootLogin without-password
while "PermitRootLogin yes" was already there.
I've then run the following command on one machine:
sudo ssh -NTCf -w 0:0
The ssh command goes background but no tun0 interface is created.
Moreover, the system log says: "tun0: Disabled Privacy Extensions"
How can I fix this thing?
Googling didn't provide any useful help so far.

Try installing the uml-utilities and try again. In Terminal:
sudo apt-get install uml-utilities
You can test if it works by creating a tun interface like this:
tunctl -u $USER

That works as root.
But it creates tap0, not tun0!
| Uqbar (uqbar) said : | #3 |
It works!
Now the command "sudo ssh -NTCf -w 0:0" has created the local tun0 interface.
On the remote machine I can also see the tun0 interface.
So the point is that I was missing the uml-utilities.
You rock, Theodotos!
Ευχαριστώ σας!

You really touch me with the Greek! You are most welcome.
I think we should add this information in the help page you reference above because it confuses people. I 'll try to contact the author.
