Hi, I have setup a diskless cluster where there is a head node (server) and a computing node (client). While settingup, I installed an image of linux using debootstrap. There is no problem with that and the node can boot and I can login to that. The problem is when I want to open a port in the client using iptables, I get some errors and have no idea about them. root@client:/home/mahmood# iptables -A INPUT -p tcp -d 0/0 -s 0/0 --dport 4949 -j ACCEPT FATAL: Could not load /lib/modules/2.6.32-24-server/modules.dep: No such file or directory iptables v1.4.4: can't initialize iptables table `filter': iptables who? (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. Any suggestion is welcomed. // Naderan *Mahmood; -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
