I had the same problem but the cause and solution is different. Perhaps it's a Mandriva thing, but the tun module is loaded in the default.nodes list in /etc/udev.devices.d. These are created independently at udev startup and so never go through the main rules - they all have permissions of 0600.
To sort it, comment out the line in default.nodes which reads net/tun c 10 200 i.e make it # net/tun c 10 200 then add the line tun to /etc/modprobe.preload now the tun will be loaded by the normal udev rules which you can edit or over-ride. In mandriva the rule is in /lib/udev/50-udev-default.rules KERNEL=="tun", NAME="net/%k", MODE="0666", OPTIONS+="ignore_remove" which you can edit to add the vboxuser group (or whatever) KERNEL=="tun", NAME="net/%k", MODE="0666", GROUP="vboxuser", OPTIONS+="ignore_remove" which is OK, but this file will be overwritten if there is a udev update and need to be edited again, so you may be better adding your own override. -- Cannot change /dev/net/tun file permissions with udev https://bugs.launchpad.net/bugs/265138 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
