Hello: I'm triying to start up vpn's with ipsec on suse7.2. I've readed the documentation from FreeSWan about soft and kernel-options requiered and before to install FreeSWan I allways got a system without compile errors or problems (first, system Ok, second try to install IPSec). I got the nexts configurations and allways with the same error: * Suse 7.2-2.4.4 + FreeSWan 1.90 (from rpm on installation CD with ipip on the kernel-option=M and Y) * Suse 7.2 with kernel 2.4.14 and FreeSWan 1.93 (from web , file tar.bz2) as suggested in the On-Line documentation * Suse 7.2 with kernel 2.4.17 and FreeSWan 1.94 (from web , file tar.bz2) That's the error that I allways got: ipsec_setup: Starting FreeS/WAN IPsec 1.9X... ipsec_setup: modprobe: Can't locate module ipsec ipsec_setup: Fatal error, kernel appears to lack KLIPS. Cannot continue IPsec startup. ..as module ipsec.o it isn't on my system, i'm trying to start-up with ipip.o (as module or kernel installed) and this the error: ipsec_setup: Starting FreeS/WAN IPsec 1.9X... ipsec_setup: /usr/lib/ipsec/klipsdebug : Trouble opening PF_KEY family socket with error : Unknown file open error 97 ipsec_setup: Cannot adjust kernel flags, no /proc/sys/net/ipsec directory ipsec_setup: /usr/lib/ipsec/eroute : Trouble opening PF_KEY family socket with error : Unknown file open error 97 ipsec_setup: /usr/lib/ipsec/spi : Trouble opening PF_KEY family socket with error : Unknown file open error 97 ..... I've readed user-list (at http://lists.freeswan.org/pipermail/users/...) and I'm confused about this : ¿ Do I need a snapshot ? ¿ Do i need to correct options in my .config kernel configuration? Any suggestion will be appreciated.
