tinc - Jun 2010 - Using tinc on planetlab

Hello,

Anyone on this list had successfully used tinc on planet lab [0] ?

I'm trying to do it but I get some problems using the tap device

tincd just keeps printing this error:
Error while reading from Linux ethertap device /dev/net/tun: File
descriptor in bad state

I guess the problem is I cannot manage tun/tap devices on the planet
lab nodes even if I am root :(
Look at this:

bash-3.2# /usr/sbin/tunctl
TUNSETIFF: Operation not permitted
bash-3.2# whoami
root
bash-3.2#

I know this is more a planetlab problem than I tinc problem and I am
offtopic, but I am really looking for some hints, so if anybody can
help me please write me an email even privately.

thanks

Saverio

It would help if you could show us what version of Linux is running on it, if
the tun module is available and loaded, and if possible send us a copy of the
kernel configuration (see if it's in /boot or try modprobe ikconfig and
reading
/proc/config.gz).

I tried now... no change in the behaviour :(
