I am running slackware11. (kernel : 2.4.33.3 I have downloaded the cttproxy-2.4.33-2.0.5.tar.gz I am trying to patch the above mentioned tproxy patch to the above mentioned kernel. I have followed the following steps: Extracted cttproxy patch to a folder. Then I passed the following commands: #cd /usr/src/linux #for i in <pathtocttproxy>/patch_tree/*.diff; do cat $i | patch -p1; done. The patching is done but it gave some errors with the message that rejects are saved to file net/ip4/netfilter/ip_conntrack_core.core. Being a Linux noob and enthuasist, I have the following questions, Have I passed the command correctly? Is tproxy patch installed, and can I proceed further? If not how to get rid of these errors? Secondly as suggested in the readme, I can not find the Directory /usr/src/iptables-1.3.5 Please help me solve the issue. Best Regards
