Hi.
I'm having some trouble setting the TOS-field in
the IP header _to an arbitrary value_
using iptables.
To manage to do this I first patched iptables
(1.2.5) and my kernel (2.4.18-3) with
the patches for FTOS. I recompiled and reinstalled
but ended up with:
# iptables -t mangle -A OUTPUT -j FTOS --set-ftos
128
iptables: No chain/target/match by that
name
"Ok? Well I might as well upgrade to latest
iptables and latest kernel-patches"
Though and done, iptables 1.2.7a installed and all
the "patch-o-matic"-patches
installed. According to the documentation the
TOS/FTOS-features was now obsolete
in favor of the DSCP option. So I tried
again:
# iptables -t mangle -A OUTPUT -j DSCP
--set-dscp 128
iptables: No chain/target/match by that
name
Well, it says somewhere that only values up to 0x4f was supported
by DSCP, but a lower values doesn't affect the error.
FTOS still seems to be part of the cose though, but same error
occurs.
What can I do to fix this? And even if DSCP works, how can I set the 8
IP-header
TOS-bits to a value between 0x00 and 0xff?
Thanks in advance
