Hello,
We recently switched to Libreswan 3.12 from OpenSwan. Over the past week
I've started having some connectivity issues with a few of my servers.
After the SA is established the following message is logged:
Apr 28 13:42:13 sanfrancisco pluto[16567]: "L2TP"[20074] <ip goes here>
#41490: unable to popen up-host command
I haven't had any luck searching for that phrase on Google thus far.
Restarting the ipsec services appears to correct the connectivity issue.
Prior to restarting the services, pluto was using a fair amount of memory:
22422 root 20 0 245m 139m 1652 S 0.0 28.2 41:24.35 pluto
versus afterwards:
24216 root 20 0 110m 6952 4668 S 0.0 1.4 0:00.17 pluto
I'm running Debian 7.x 64bit on my servers. My monitoring infrastructure
will set up short-lived tunnels to the servers to verify that they are
accepting connections and able to properly route traffic. Let me know if
there's anything else I can provide to help diagnose this.
Thanks,
--Will
