Hi I need help with tproxy. Am trying to get it to work with squid-2.6.STABLE16 but I get the popular missing ip_tproxy.h header file error while compiling: "checking if TPROXY header files are installed... no WARNING: Cannot find TPROXY headers, you need to install the tproxy package from: - lynx http://www.balabit.com/downloads/tproxy/ " I run Debian with kernel 2.6.22 compiled with tproxy 4.0.3 support already. I followed the instruction for patching the kernel and iptables-1.3.8. I can load the iptable_tproxy module: candy:~# modprobe iptable_tproxy candy:~# lsmod Module Size Used by iptable_tproxy 6404 0 ip_tables 11592 1 iptable_tproxy ipv6 225508 12 dm_snapshot 16416 0 dm_mirror 19712 0 dm_mod 50624 2 dm_snapshot,dm_mirror 8021q 18952 0 xt_tproxy 2048 0 x_tables 14084 2 ip_tables,xt_tproxy reiserfs 216832 1 loop 16260 0 pcspkr 2944 0 rtc 11672 0 i2c_piix4 8460 0 i2c_core 23696 1 i2c_piix4 ext3 118792 1 jbd 49832 1 ext3 sd_mod 27280 5 aic7xxx 160600 3 scsi_transport_spi 23296 1 aic7xxx scsi_mod 134540 3 sd_mod,aic7xxx,scsi_transport_spi tulip 47776 0 candy:~# dmesg | grep TPROX IP_TPROXY: Transparent proxy support initialized, version 4.0.0 IP_TPROXY: Copyright (c) 2002-2007 BalaBit IT Ltd. I can add iptables rule with tproxy without any problem: candy:~# iptables -t tproxy -A PREROUTING -j TPROXY --on-port 3128 candy:~# iptables -t tproxy -L Chain PREROUTING (policy ACCEPT) target prot opt source destination TPROXY all -- anywhere anywhere TPROXY redirect 0.0.0.0:3128 candy:~# My problem is the missing ip_tproxy.h file. Its not anywhere in my /usr/src/linux. I have searched everywhere for a solution the past 7 days with no luck. Please help me as am flat out of ideas! Thanks in advance. Sonny.
