Hi All, Simple problem, although I'm sure it's been raised before and I need to search harder! I've got a basic setup/configuration of iptables-1.2.11-3.1 running on 2.6.10-1.766_FC3smp with one change in the /etc/sysconfig/iptables-config file. I increase the hashsize using: /sbin/modprobe ip_conntrack hashsize=32767. If I run service iptables stop/start and then cat /proc/sys/net/ipv4/netfilter/ip_conntrack_buckets the value is 32767. If I run service iptables restart the value in the file goes back to default. I've noticed the same in a power failure scenario where the machine lost power and on reboot didn't change the hashsize. I've had a quick look through /etc/init.d/tideway and as far as I can tell a restart just runs a stop and start. I'm assuming some sort of save/restore flag is or isn't set and this is causing the problem during a restart or power cut. I need to ensure that the correct hashsize is always set. Any have any ideas? Thanks
