I’m setting up Ipsec on ubuntu:
apt-get install racoon
ran into problems:

apt-get remove racoon
modprobe crc32c modprobe ipcomp6
apt-get install racoon
same thing, maybe the errors are OK?
This the problem from syslog?
racoon: ERROR: glob found no matches for path
This page translated:
and it worked!

Still not working, now getting this error in syslog:
racoon: ERROR: couldn't find configuration.
get pfkey X_SPDDUMP message pfkey X_SPDDUMP failed: No such file or directory
Hmmm, what is pfkey - restarted setkey and its good, then had some mismatched encryption settings. Now this:
racoon: ERROR: couldn't find the pskey
Hmmm. Got that working - you really have to make sure all the setting match up on both side. The sa gets established, but I can’t ping one box from the other. Though packets are getting through (as seen via tcpdump). The issue now must be something to do with iptables, routing, or something similar.
Argh. I just couldn’t get this working, but I did learn a lot about ipsec on ubuntu / debian. I need to test it out on another server to make sure the problems I was having aren’t isolated.
