Hello, I'm using Debian GNU/Linux and I'd like to get iptables working with the tarpit function. I have my 2.6.8 kernel in /usr/src/linux. I've downloaded patch-o-matic with cvs as told in the netfilter modification tutorial. It created me /usr/src/linux/netfilter and /usr/src/linux/netfilter/patch-o-matic (no /usr/src/linux/netfilter/userspace as told in the tutorial). After that I launch ./runme ./extra/ipt_TARPIT.patch and if I apply the patch : Testing patch extra/ipt_TARPIT.patch... Warning - no help text file could be found in either /usr/src/linux/net/ipv4/netfilter/Config.help or /usr/src/linux/Documentation/Configure.help grep: /usr/src/linux/net/ipv4/netfilter/Config.in: Aucun fichier ou répertoire de ce type Could not find place to slot in Config.in line TEST FAILED: patch NOT applied If I force with f : Applying patch extra/ipt_TARPIT.patch... Warning - no help text file could be found in either /usr/src/linux/net/ipv4/netfilter/Config.help or /usr/src/linux/Documentation/Configure.help grep: /usr/src/linux/net/ipv4/netfilter//Config.in: Aucun fichier ou répertoire de ce type Could not find place to slot in Config.in line grep: /usr/src/linux//dev/null: Aucun fichier ou répertoire de ce type Could not find place to slot in null entry Could not find place to slot in Makefile line Patch extra/ipt_TARPIT.patch applied cleanly. But I can't find the tarpit item when I use make xconfig which should be in networking_options -> network packet filtering -> IP:Netfilter configuration Thanks for your help because I spent a lot of time trying to figure this out... I'm quite sure it's something quite silly that I forgot to do ... Nicolas
