Hi All,
I have successfully built a firmware for a WRT54GS out of DD-WRT-SP1 Final and also DD-WRTSP3 sources. However in both cases the "iptables" executable does not work, and, no matter in which way I call it, I always get the following error:
# ./iptables -L
iptables: match `layer7' already registered.
If I replace the "iptables" executable in my build with an executable taken from one of the DD-WRT firmwares (I extract it using "extract_firmware.sh") than, "iptables" works as expected. Therefore there must be something wrong with the way it is built.
Has anyone bumped into this issue and has found a solution for it?
Why do you use ./iptables instead of just iptables?
Because after the first three or four times when I reflashed the router with the firmware I built containing a bad "iptables", I built a firmware getting a good "iptables" from a dd-wrt built firmware, than I built iptables again several times, using several different parameters, and also different compilers. Instead of each time re-building a new firmware and re-flashing the router, I copied the executable in a directory mounted with samba share and executed it from there with ./iptables.
When I used "iptables" extracted from a dd-wrt distributed firmware it worked, none of the executables that I have built worked.
The odd thing is that everything else seems to work just fine.
Guys, I need your help here, could anyone come back to me explaining how to build iptables successfully? Nedless to say that I have followed litterally the instructions in the wiki.
Anybody has solved this problem?
I'm trying to compile DD-WRT-rev3934 - everything compiles properly, but when I'll upload the firmware and try to use iptables over telnet, I get the same error as haydude:
iptables: match `layer7' already registered.
It woildn't be a big problem, but internet line sharing is not working because of this.
Disabling layer7 was successfull, but I want to use it with my DD-WRT.
Anybody solved this problem finally? _________________ Kissiel
