Is there anyone know how to temporary get rid of sit0 from FC2? After I installed the FC2 and run "ifconfig -a", I got sit0 at bottom of the output. I known the system had loaded Ipv6 module or maybe compiled into kernel. But I just wanna temporary unload or delete the IPv6 module from the system for short term and I hope I can load the IPv6 module again when I need to use it! I searched for a while but got nothing. Any comments about this usage? Thanks in advance.
