Hi, I''ve got the same trouble few week ago but on Mandriva: "I''have try to use shorewall 2.4.7 on Mandriva 2006 ( Kernel 2.6.12.12mdk ). Every things right, but when i actived provider, i''ve got a kernel panic with "Bad EIP" & "dereference at virtual address 0000000". I''ve upgrade shorewall to 3.0.3 and modify the config files to respect new directives => Kernel panic. I''ve upgrade the kernel to 2.6.12.14mdk => Kernel panic. Finally, i''ve downgraded to kernel 2.6.11.6 => no more kernel panic. It work with the kernel 2.6.11.13 to." Try the kernel 2.6.11. It seems to be ok Franck -----Message d''origine----- De : Russel [mailto:rusabus@hotmail.com] Envoyé : mardi 21 février 2006 16:04 À : shorewall-users@lists.sourceforge.net Objet : RE: [Shorewall-users] Server with shorewall hangs - 2 ISP config Marco - I had a similar problem when implementing the multiple ISP setup on my box. It''s a Celeron 333 with a Micronics C300 motherboard, 192 MB RAM, Intel I740 video card, and 5 3com 3c905tx network cards. When I was running FC4 with a 2.6 kernel, I had all sorts of problems with my server locking up. Mine, however, only took about 30 seconds before crashing. If I removed the balance entry in the providers file, everything worked fine. It seemed to be related to the multi-hop gateway that is created when the balance option is used. Jerry provided some revised networking init scripts that could build the multi-hop gateway for me independently of Shorewall. The scripts worked fine, but after the multi-hop gateway was created, my kernel would panic within about 30 seconds. I eventually compiled my own kernel with only the options my machine needed, and that helped. My kernel still panicked, but it took about 5 minutes. I suppose that if I had continued to tweak the kernel options I might have been able to fix it, but since I''m relatively inexperienced with it, I decided to try something else. I switched to Debian 3.1 with a 2.4 kernel. I had to re-compile the kernel several times to get all the correct options necessary for the "track" option to work in the providers file (all the CONNMARK stuff - plus I didn''t know what I was doing). Once all the correct netfilter options had been included in the kernel and iptables was correct, I had a working machine. A few weeks ago I started on a project that might have been easier using a 2.6 kernel, so I backed up my hard drive and re-formatted using SUSE 10 with a 2.6 kernel. After configuring the multiple ISP setup, I got kernel panic in just a short time. I re-formatted and installed Debian 3.1 with the 2.6 kernel. Same problem. You might want to try installing a 2.4 kernel on your box and see if that helps. If you''re more skilled than I am at kernel stuff, it might be possible for you to down-grade without reinstalling FC4. If it were me, I''d just format and reinstall. (To avoid problems with stuff like udev, which only runs on >2.6.?? kernels.) If you do install a 2.4 kernel, you''ll need to use patch-o-matic to patch your kernel sources and enable the required CONNMARK target and connmark match support options (that means re-compiling). You will probably also have to re-compile iptables to get those options working. After installing the newly-compiled iptables, you might have to change the IPTABLES option in shorewall.conf to point to the correct location of iptables. Mine is in /usr/local/sbin/iptables. I suspect that there might be a bug in the 2.6 kernel that was causing my problem, but I haven''t pursued that suspicion or submitted a bug report to the kernel developers. Since I don''t know if this is an actual kernel bug, my advice may lead you to the exact same point where you are right now, but it worked for me (tm). -Russel ________________________________________ From: shorewall-users-admin@lists.sourceforge.net [mailto:shorewall-users-admin@lists.sourceforge.net] On Behalf Of Marco Vescovi Sent: Monday, February 20, 2006 4:53 PM To: shorewall-users@lists.sourceforge.net Subject: [Shorewall-users] Server with shorewall hangs - 2 ISP config Hi all, I''ve a little server, an old PIII 677 with Fedora Core 4, default kernel, and Shorewall 3.0.1. This pc is working fine, but I need to use a 2nd ISP connection; everything is working from configuration point of view, but the server, after a while (usually few hours), just hangs. Removing the 2-ISP configuration part, the problem is solved, so I''m quite sure that hangs are related to that point. I tried searching in all system logs, but I didn''t find anything interesting, also I googled around and nothing seems to give e some idea.
