Paul, : The filter -> tc filter add dev eth1 parent 1:0 protocol all prio : 1 u32 match u8 0x6 0xff at 9 match u32 0xa640105 0xffffffff at 16 : offset at 0 mask 0f00 shift 6 eat link 5:0:0 : : Can anyone please tell me how to change it ? : : I've being searching and trying to make sense of the man pages : all day. Is this related at all to your prior question [0]? The above 'tc filter' command looks like something created by the tcng processor (tcc). If indeed you are using tcng, I would suggest solving the problem with that tool, rather than trying to understand the masking, shifting, matching and eating with a bare 'tc filter' command. -Martin [0] http://mailman.ds9a.nl/pipermail/lartc/2006q2/019106.html -- Martin A.
