Hi, I've been using squid 3.0 stable and figured it was time to upgrade to 3.1 series. Since 3.1 series requires IPFIlter (amongst others) I downloaded 5.1.0 from http://coombs.anu.edu.au/~avalon/. (Is this the right one?) I couldn't get the IPFIlter to build due to some errors: /st/curinsts/ip_fil5.1.0/Linux/Linux-2.6.32.8-sapphire-i686/ip_film.c: In function `ipf_fastroute': /st/curinsts/ip_fil5.1.0/Linux/Linux-2.6.32.8-sapphire-i686/ip_film.c:548: error: structure has no member named `fd_ifp' /st/curinsts/ip_fil5.1.0/Linux/Linux-2.6.32.8-sapphire-i686/ip_film.c:614: error: structure has no member named `dst' /st/curinsts/ip_fil5.1.0/Linux/Linux-2.6.32.8-sapphire-i686/ip_film.c:615: error: structure has no member named `dst' /st/curinsts/ip_fil5.1.0/Linux/Linux-2.6.32.8-sapphire-i686/ip_film.c:616: error: structure has no member named `dst' /st/curinsts/ip_fil5.1.0/Linux/Linux-2.6.32.8-sapphire-i686/ip_film.c:619: error: structure has no member named `dst' make[3]: *** [/st/curinsts/ip_fil5.1.0/Linux/Linux-2.6.32.8-sapphire-i686//ip_film.o] Error 1 make[2]: *** [_module_/st/curinsts/ip_fil5.1.0/Linux/Linux-2.6.32.8-sapphire-i686] Error 2 make[2]: Leaving directory `/usr/src/linux-2.6.32.8' make[1]: *** [ipflkm] Error 2 make[1]: Leaving directory `/st/curinsts/ip_fil5.1.0/Linux' st@sapphire:~/curinsts/ip_fil5.1.0# Since I can't build IPFilter.. I don't have the benefit of the Transparent Proxy for Squid. I now can only use the Interception proxy. (I'm on a Linux box btw. Slackware 13.0 or actually a heavily modified 12.0 distro). Is this the same as the old transparent method from the 3.0 series of sQuid? Thanks Ed
