Strange logs -> losing OpenVPN connection every 20 - 120 seconds
-
I reverted back to
2.1-RELEASE (amd64)
built on Wed Sep 11 18:17:48 EDT 2013and this oddity is gone for good. Guess I'm going to stick to that for a some more time!

The system log isn't all that telling on its own, what does the OpenVPN log show?

Still happening even with latest snapshot. The WAN IP is in fact static, it never changes. These newwanip detections are a pile of BS.
rc.newwanip: pfSense package system has detected an ip changeSame thing happens with IPsec:
php: rc.newipsecdns: IPSEC: One or more IPsec tunnel endpoints has changed its IP. Refreshing.As for OpenVPN log, nothing useful there either:

Every time a connection/reconnection occurs you see the logs for newwanip.
Do you have anything similar to below in your logs?
log_error("DEVD Ethernet attached event for {$iface}"); log_error("HOTPLUG: Configuring interface {$iface}");Give this a try again as well:
diff --git a/etc/rc.linkup b/etc/rc.linkup index 1994336..43607b1 100755 --- a/etc/rc.linkup +++ b/etc/rc.linkup @@ -100,7 +100,7 @@ if (!file_exists("{$g['varrun_path']}/booting") && empty($g['booting'])) { break; } $interface = convert_real_interface_to_friendly_interface_name($argv[2]); - if (!empty($interface)) + if (!empty($interface) && substr($argv[2], 0, 4) != "ovpn") handle_argument_group($interface, $action); } -
No, no hotplug/devd events in the log. As for the patch, well yes I can try that (should obviously stop triggering the OVPN restart), but it's not really like it'd happen for any good reason at all. It seems like it just decides the WAN IP "changed" a couple of times a day, randomly.

Well if your Dyndns or any other monitoring for hostname changes triggers the event you have to find which is doing that.
Also find out why its triggering the event.To me from the logs it looked like devd was doing that since it was not clear on dyndns/hostnames on vpns being used from the logs.
Maybe the config.xml can help to validate the options here.

Now that you mention dyndns…

The GW IP never changes, it is configured as static IP on the GIF interface. What's "updating" there? Again, the WAN_DHCP is a static DHCP lease, never changes.

Can you check the relevant files for this to see why it triggers?

Maybe… if only I knew the relevant files. :D
