Hello Bob. Bob McGowan, 01.03.2007 20:53:I'm trying to set up bridged networking for a Qemu guest system. The doc I have says I need to do a 'chmod 666 /dev/net/tun' to be able to do this. And, I see the permissions on it are: crw------- 1 root root 10, 200 2007-02-27 16:28 /dev/net/tun So, methinks, I should fix the udev configuration so it sets the permissions to 666 rather than 600. Only one problem. /etc/udev/permissions.rules says: KERNEL=="tun", MODE="0666"On my system there is a /etc/udev/tun.rules file which seems to set up the device and its permissions:$ grep -r tun /etc/udev/* | grep 666 /etc/udev/permissions.rules:KERNEL=="tun", MODE="0666" /etc/udev/rules.d/020_permissions.rules:KERNEL=="tun", MODE="0666" /etc/udev/rules.d/010_tun.rules:KERNEL=="tun", NAME="net/%k", MODE="0666" /etc/udev/tun.rules:KERNEL=="tun", NAME="net/%k", MODE="0666"You might want to try looking for it or creating it if necessary.

Thanks for the suggestion. It had no impact on device permissions or creation, when I added it.
Thanks to all for your ideas. Given that I need a bit more than just this file permission change, to use tun/tap as a user, I've decided the simplest solution, for now, is to just add the commands needed to set things up in the /etc/rc.local file. This way I can run the bridge setup, tunctl, and chmod command as root during boot and so have it available whenever I need to run Qemu.
Thanks for all the suggestions. Bob
