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

...Red Hat's 2.4.18-3??? _First!_ see:
'http://rhn.redhat.com/errata/RHBA-2002-292.html',
'http://rhn.redhat.com/errata/RHSA-2002-262.html',
'http://rhn.redhat.com/errata/RHSA-2002-206.html'...etc,
_act_ on them. Then retry your stunt.

Scenarios always come in sets of three:
best case, worst case, and just in case.
