I am trying to resolve an issue with the patch-o-matic in regards to the pptp nat and conntrack patch. I am using kernel 2.6.12.3 on many different processors. I have the problem across the board. I can compile, but I can load the module. I get an error in dmesg: ip_conntrack_pptp: Unknown symbol __ip_conntrack_expect_find ip_nat_pptp: Unknown symbol ip_nat_pptp_hook_inbound ip_nat_pptp: Unknown symbol ip_nat_pptp_hook_expectfn ip_nat_pptp: Unknown symbol ip_nat_pptp_hook_exp_gre ip_nat_pptp: Unknown symbol ip_nat_pptp_hook_outbound If I try to load ip_nat_pptp I get: in:~# modprobe ip_nat_proto_gre in:~# modprobe ip_nat_pptp WARNING: Error inserting ip_conntrack_pptp (/lib/modules/2.6.12.3/kernel/net/ipv4/netfilter/ip_conntrack_pptp.ko): Unknown symbol in module, or unknown parameter (see dmesg) FATAL: Error inserting ip_nat_pptp (/lib/modules/2.6.12.3/kernel/net/ipv4/netfilter/ip_nat_pptp.ko): Unknown symbol in module, or unknown parameter (see dmesg) Does any one know which patch-o-matic would work with the 2.6.12.3 kernel? I am using patch-o-matic 20050913? Or how to resolve this issue?
