RES: ADVANCED ROUTING USING IPROUTE2 -> Multiple Firewalls
Hi William. Thanks a lot for your help. Im having some trouble recompiling my kernel after a installed the patch. Im running RH 7.3 with kernel 2.4.18-3. The patch I installed is routes-2.4.16-6.diff. I got no errors installing it. I added the multipath support, and recompiled it. The make dep and the make bzImage went fine. I got error during the make modules. These are the errors: Output.c: in function ''cipe_xmit'' Output.c:175 too few arguments to function ''ip_route_output'' Make[3]: *** [output.o] error 1 Make[3]: leaving directory ''/usr/src/linux-2.4.18-3/drivers/addon/cipe'' Make[2]: *** [_modsubdir_cipe] error 2 Make[2]: leaving directory ''/usr/src/linux-2.4.18-3/drivers/addon'' Make[1]: *** [_modsubdir_addon] error 2 Make[1]: leaving directory ''/usr/src/linux-2.4.18-3/drivers Make: *** [_mod_drivers] error 2 After I got that error, a formatted and reinstalled redhat 7.3. Then I used the newer patch (routes-2.4.19-8.diff), and I got error installing, and of course I couldn''t recompile it. I formatted again to see if I were doing something wrong recompiling. But this time I didn''t patch and recompile it. I got no errors... Any ideas? Am I using the wrong patch? Thanks a lot, Ron -----Mensagem original----- De: William L.

Also before you compile apply Julian''s patches to the kernel. http://www.linuxvirtualserver.org/~julian/#routes Once that is done check out the Nano-HOWTO http://www.linuxvirtualserver.org/~julian/nano.txt That should get you on your way. The linux router will also have to perform NAT, more than likely DNAT, for things to work properly. On Thu, 2002-06-13 at 07:43, Roni Reicher wrote:> Hi guys.

It does not have the problem to change the interface of the routing functions, so such problems with applying extra patches to code out of the plain kernel should not exist.> RonRegards -- Julian Anastasov <ja@ssi.bg>
