Til: Alan Cox To Alan Cox! Hi Alan, I am working on a master thesis called =93Internet Protocol version 6=94. In the project I have to setup a test-network for analyzing the RIPng pro= tocol=20 etc. I am using four normal Intel PC=92s each running Debian Linux, with = a custom=20 compiled kernel 2.4.19 downloaded from www.kernel.org. Two of the PC=92s = are=20 running as a software-based router (using Zebra 0.92a-6), and the other i= s=20 separately working as a client and server, respectively connect to router= 1 and=20 router2. My problem is when I try to send an ICMPv6 request via the WAN-link (rout= er1=20 and router2) from the client, I not getting any response from server. The= =20 problem only appears when I try making a connection via the WAN-link, and= not=20 from router1<->server and router2<->client. My question is: - Could a problem be due to a wrong kernel-configuration? (I can attach=20 the .config if you are interested). - What "kernel mechanism" is responsible for routing/transporting data be= tween=20 two interfaces? (I think that=92s the problem in router1 and router2. Zeb= ra is=20 only exchanging the "IPv6 kernel routing information" between router1 and= =20 router2, and it is working fine). - What kernel version have most IPv6 features build-in ?? (Maybe a featur= e is=20 missing in 2.4.19. I have read an article about patching the kernel:=20 http://project6.ferrara.linux.it/papers/best_ipv6_support_4_linux/best_ip= v6_supp ort_4_linux.html, it is necessary?). I hope you understand what my main problem is =96 English is not my prima= ry=20 language. I have got many information from mailinglists, messagesboards and homepag= es,=20 but the main problem is, that those information is conflicting. That=92s = why I=20 writing to the Linux Guru him self.=20 Btw. You are doing a very good job with the Linux kernel!
