Where to start recopiling the gpl code.

Thanks omega an apleman
I recompiled the kernel and now it works.
One more thing.
Whe i configured the n1200 kernel i selected "packet mangle" option.
I used the Ipt_ttl.ko file and loaded into the nas using insmod.
everithing was fine. the module was laoded.
i check it with lsmod.
then i used the command:
iptables -A PREROUTING -t mangle -d wan_ip -j TTL --ttl-set 21
for ttl modify.
iptables -A PREROUTING -t mangle -d 192.168.2.254 -j TTL --ttl-set 21
iptables v1.3.5: Unknown arg `--ttl-set'
Try `iptables -h' or 'iptables --help' for more information.i get the error

what other modules do i need to load for modifi tt?

help please

Why don't you use the actual version of iptables 1.4.1.1 (get it HERE)?

Most likely the --ttl-set is not available in the version you use (more than 18 month old).

The same thing will happen if i compoile that.
Looks like you have no idea what ttl modify is. ip tables has nothing to do with it

[omega]

Looks like you don't know what your real problem is....

You've quoted this error:

iptables v1.3.5: Unknown arg `--ttl-set'

and at least my iptables understands the arg --ttl-set.

So why doesn't it have something to do with iptables?
You should be more clear in what you say..

You may want to run patch-o-matic or patch-o-matic-ng on the kernel your building or update your version of iptables like omega says. The ttl part comes as a module which the default thecus version may not have.

[badboy1985ro]

Sorry. You are write.
Know i understand. On other firmware like OpenWrt this part was not necesarry.
Sorry again.

How do i run patch-o-matic or patch-o-matic-ng or update the iptables on nas?

I don't have a serial cable so this method is out of the question.

[appleman1234]

I dug a little deeper, the problem is that /lib/iptables/libipt_TTL.so doesn't exist in /initrd/usr/local/lib/iptables/ .

You can fix this two ways, one you can obtain a libipt_TTL.so for ppc iptables 1.3.5 and put it or symlink to the directory, or make a thecus module which does that or two you can update iptables to the latest ppc debian binaries and files and make both the libipt_TTL.so and the new iptables in a thecus module and install it.

For thecus module development information please see onbeat.dk/thecus/downloads/ModuleHowto.pdf and onbeat.dk/thecus/index.php/N1200_Module_Development or take a look at the source for the SSH module or one of my modules that are mentioned on the same site.
