Hello,

i have this problem:

in the HW i configure a tunnel 6to4:

ip tunnel add 6to4 mode sit local IP_Address ttl 255

and when i use the netdev_add for use the 6to4 into the vps i have this error:

vzctl set 120 --netdev_add 6to4 --save
Unable to add netdev 6to4: Operation not permitted
Saved parameters for CT 120

any ideas?

Thank You.

"Operation not permitted" must be a return value of some system call. Please, try using "strace" utility to reveal what system call returns such a value.

Hi,

the provided output is "touch /tmp/file" strace output.
But the command that doesn't work is "vzctl set 120 --netdev_add 6to4 --save"
