Hello,
I am trying to change the OS fingerprint with iptables. Here are two
rule set which I have constructed to do the same
````````
iptables -t mangle -A PREROUTING - -j PERS --tweak dst --local --conf
example/win9x.conf
iptables -t mangle -A OUTPUT -j PERS --tweak src --local --conf
example/win9x.conf
````````````
But it throws an error like
``````````
iptables v1.4.2-rc1: Unknown arg `--tweak'
Try `iptables -h' or 'iptables --help' for more information.
```````````````
What might be the problem here ?
Thanks

I'm not familiar with the PERS target. It does not show up in my
iptables. Is it available in your kernel or do you need to load and
perhaps compile a module for it? - John

I am not very sure but maybe we need to patch the kernel. Any clue from
anyone ?
Thanks

The package required to change the IP personality can be found here...
http://ippersonality.sourceforge.net/
Follow their directions and your distributions module build process to
make sure you have the required modules/user space libraries (if
needed) compiled and working.

Thanks a lot. I'll test in my debian box.
