Hi all, I need to use the FTOS target. Took me quite a while to figure out how to get it 'available' for use. (I added 'FTOS' to the PF_EXT_SLI field of the Makefile in the extensions directory of the 1.2.9 distro and that seems to have done the trick. After running make and make install the libipt_FTOS.so file gets copied into /usr/local/lib/iptables). I'm having trouble using the correct syntax for a rule though. This rule,using TOS, works fine: iptables -I OUTPUT -t mangle -j TOS --set-tos 0x02 Trying the same thing with FTOS: iptables -I OUTPUT -t mangle -j FTOS --set-ftos 0x02 Produces the error message: iptables: No chain/target/match by that name Looks weird. Interestingly, if I don't provide the --set-ftos argument I get a logical error message: iptables v1.2.9: FTOS target: Parameter --set-ftos is required So it looks like FTOS can be used but I'm doing something wrong with the --set-ftos argument. I'm running a 2.4.20-8 kernel on RH9. Thanks, Mark. ‘The ideals which have lighted my way, and time after time given me new courage to face life cheerfully, have been kindness, beauty, and truth.
