17 | # A daemon to monitor attempts to create GRE-over-IPsec tunnels. | |
18 | # Uses racoon and setkey to support the configuration. Assumes that | |
19 | # OVS has complete control over IPsec configuration for the box. | |
20 | ||
21 | # xxx To-do: | |
22 | # - Doesn't actually check that Interface is connected to bridge | |
3c52fa7b JP |
23 | # - If a certificate is badly formed, Racoon will refuse to start. We |
24 | # should do a better job of verifying certificates are valid before | |
25 | # adding an interface to racoon.conf. | |
