XMLRPC sync errors since upgrade to 2.4.4
-
Is the webgui healthy on the secondary at the time? Can you log in there and navigate?
Are you trying to game things without the requisite 3 public IP addresses on WAN? Can the secondary get to the internet, resolve names, etc when it is not CARP master?

Yup, the webgui is just fine. I'm not trying to game anything, both firewalls have their own unique upstream address, and the CARP address is a different and also unique address as well. The secondary firewall can get to the Internet and resolve DNS names when it's not CARP master, I pinged google.com to check.

is 172.16.1.3 the sync IP or the LAN IP of the second router?@windiz
same question for 10.51.0.2?The routers I upgraded last week aren't logging comm errors...
A long time ago I did have sync issues. I seem to recall I tracked it down to Suricata and that we had selectively disabled many of the unneeded individual rules. Turns out all that had to sync and it was timing out. Solution: don't disable individual rules and it has less to process.

That's the sync IP for the second firewall. The primary's is 172.16.1.2.

@nima304 Thanks for digging into your setup to get to the bottom of this. I just haven't had time on my end and since things more or less work, it hasn't been a priority.
-
Do you have a large number of users in the config?

No problem, hopefully there's a resolution that solves it for all of us.

No, literally just the admin user, but I also have LDAP auth configured.
-
That should be no problem as long as the user accounts are not on pfSense. A large number can introduce delays on the secondary when the sync'c config is added preventing it responding in reasonable time.
Hmm, I'd probably start a packet capture on the secondary sync interface. Set it for a large number and wait for it to fail. See what's actually happening there.

In windiz's logs, it is exactly 60 seconds from the beginning of the sync to the error and that sounds like a timeout to me. Brainstorming, how large is your config export file? We have some decently complex ones for our data center that are about 180 KB, for reference...Suricata rules, pfBlockerNG, OpenVPN, etc.
Router2 isn't set to sync back to router1 is it? That would be a loop.
-
Yes, the timeout is 60s. It used to be possible to take longer than that to load the config and respond with more than ~50 users on some hardware. There have been improvements gone in since then though.

Good catch, my logs are showing the same thing. While config sync isn't set at all on the secondary, the primary is syncing states from the secondary, and the secondary from the primary, as per pfSense's documentation.
I'm going to try to blow the firewall rules open on the sync interface for both firewalls and see if that does anything.
-
Blowing open the rules did nothing, unfortunately. I'm seeing data received on the secondary firewall, so it's not a cable issue. I'll do a packet capture and see if anything interesting turns up.
-
The transmission is encrypted using TLS, so I can't actually see what's going on.
-
You could set the GUI to http just while you test. However you should still be able to see the TCP sequence and lack or responses.
Make sure both nodes are time sync'd and then compare the log entries. Does the secondary log anything during that 60s window?Steve

Hello All,
I am facing the same issue after an upgrade from 2.4.3 to 2.4.4, I have gone through all the checks suggested on the thread and most are ok with the exception of an entry in Secondary system logs under the general tab. The error is XMLRPC unbound /var/unbound/root.key corrupt deleted and recreated each time a sync is performed.
On the primary node I will get the sporadic XMLRPC communication errors stated here. Please note the sync is successful and the changes from the primary are reflected on the secondary with some delay. This only started after the upgrade.

I'm facing exactly the same issue. And after upgrading to 2.4.4p1 from 2.4.3
Settings are replicated, however I see this on the secondary.nginx: 2018/12/17 16:36:37 [crit] 79693#100242: *18691 SSL_write() failed (SSL:) (13: Permission denied) while sending to client, client: 192.168.50.3, server: , request: "POST /xmlrpc.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm.socket", host: "192.168.50.4"50.3 is the primary and 50.4 is the secondary
Any ideas?It looks like the config is received but the ack is never send back to the primary, thus the complaint.
-
Permission denied is almost always something being blocked by policy.
Are you running snort or suricata?
Is it enabled on the sync interface?
-
@derelict No snort or suricata ever installed. Not even pfblocker.
-
Do you see that same error if you just save the Unbound settings page on the secondary without making any changes?
Does Unbound actually start on the secondary?
Is the filesystem full?
