[Openswan Users] Trouble getting NAT-T patch to work

[Jonathan Larsen]

I am using Slackware 12.1 for my servers which runs Kernel 2.6.24.5.  I have had no luck with the patch working, just get 6 hunk failures on udp.c.  So i've downloaded kernels directly from kernel.org.  the one i've had the most luck with is 2.6.19.  I am also using openswan 2.6.19.  Patch works fine.  Recompile the kernel, no problem.  go to make module in the openswan dir and i have problems.  Maybe there is a recommended kernel to use?  Below is the compile issues i had with make module.

ln -s -f /usr/src/openswan-2.6.19/linux/net/ipsec/ipsec_xmit.c /usr/src/openswan-2.6.19/modobj26/ipsec_xmit.c
