When starting QEMU, I am having problems configuring the tun device (tun0) as a user. Qemu runs the /etc/qemu-ifup script (as root?) which configures and then adds the tun device to the bridged eth0 device. It works as root, and worked in FC3 once I changed permissions on the /dev/net/tun device. [tkemp@systems-fc4 ~]$ ls -al /dev/net/tun crw-rw-rw- 1 root qemu 10, 200 Jun 24 00:36 /dev/net/tun [tkemp@systems-fc4 qvm]$ cat /etc/qemu-ifup #!/bin/sh /sbin/ifconfig $1 0.0.0.0 promisc up /usr/sbin/brctl addif br0 $1 [tkemp@systems-fc4 qvm]$ ./startxp Connected to host network interface: tun0 SIOCSIFADDR: Permission denied SIOCSIFFLAGS: Permission denied SIOCSIFFLAGS: Permission denied SIOCSIFFLAGS: Permission denied can't add tun0 to bridge br0: Operation not permitted /etc/qemu-ifup: could not launch network script [tkemp@systems-fc4 ~]$ ls -al /usr/sbin/brctl -rwxr-xr-x 1 root qemu 23912 Mar 3 03:36 /usr/sbin/brctl I tried adding a 'qemu' group and adding myself to that but am not having any luck. setenforce 0 doesn't help. What is locking me out? Terry
