Re: [suse-security] URGENT: SuSE 8.0 freezes when using iptables..
I have now tried a minimum firewall setup from the Iptables tutorial from www.iptables.org (http://www.iptables.org/documentation/tutorials/blueflux/). It works!!! I have tried to disable ip_conntrack_ftp from /sbin/SuSEfirewall2 by commenting it out the modprobe. But the server still crashes.. I have also tried to copy all of the modprobe's from the tutorial into /sbin/SuSEfirewall2 - No change! The reason why I would like to get SuSEfirewall to work is to setup a firewall without having to learn all about iptables - I'm a programmer not a sysadm and just need a setup to protect our office computers. Does anyone now a good step by step guide: Howto setup iptables firewall with VPN gateway??? /Christian Bjørnbak On Sunday 14 July 2002 14:35, you wrote:
Hi There,

After the upgrade when using some protocols like ftp the server freezes and the caps lock and scroll lock LED's on the keyboard blinks.
IIRC this indicates a Kernel Panic and the machine is now unusable. You could try stopping the FTP Conntrack agent (should be /lib/modules/2.4.18-4GB/kernel/net/ipv4/netfilter/ip_conntrack_ftp.o) from being loaded with the firewall on a temporary basis but it would mean no FTP sessions would survive - though Passive FTP should be handled by the default Related/Established rules. Was the upgrade a fresh install or an over-install to update the 7.2 installation to 8.0? If the latter there's a chance that some older libraries are on the system due to 8.0 having a different directory structure and they are causing the problem.
Sorry I can't help more - good luck :)
