Hello Another way to disable the IPV6 is: - edit /etc/sysconfig/network/config - set USE_IPV6=no - exit. - run "rcnetwork restart" It was tested under SUSE but probably works on Fedora. Doesn't requires computer restart...

This can be done, by putting the following lines into /etc/modprobe.conf: alias net-pf-10 off alias ipv6 off Reboot, then xmaple should run fine. --
