2.5 RC Testing

zleppy · Feb 11, 2021, 2:51 PM

@tomahhunt I've seen something similar happening. But mostly after a restart. Try restarting the "dns resolver" service next time under the service tab.

The service icon will be showing green but it wont resolve anything. Couldn't find anything specific in the logs either.

I did an upgrade-in-place from 2.4.5 on wed using the 2nd RC spin. So far it's been stable. The upgrade process itself was a total snore (that's a compliment) -- can't recall the last time an upgrade "just worked" without issues and I wasn't upgrading a mobile device.

I see a new spin dropped this morning, I'll roll that one when I can find a window in the workday while simultaneously distracting my family away from the network. :-)

ESX VM, Dual WAN (1 Gb Pri, 50 Mb failover), 5 subnets, OpenVPN

@jd-0 And no sooner than I wrote the previous, our Gb link started taking some errors (work going on in the neighborhood). As expected, pfsense smoothly dropped that gateway and favored traffic over to the backup, then switched back when the packet errors cleared.

@jd-0 One small glitch -- my running 2.5.0 build didn't swap dynamic dns (easyDNS) for VPN back from the failover event after the primary was restored. Going into the Dynamic DNS client page and forcing save/update swapped it back. Will update if this recurs on future spins. Looks like it simply didn't trigger at all as I have email notifications set up and I normally receive notification of the DNS switch when the the links failover/giveback, but nothing this time after it switched back beyond the normal notification that the gateway had been re-added to the group.

I upgraded my test system to 2.5.0 RC yesterday. Today when I returned to take a look, the pfsense webgui was dead. The console was still operational. I rebooted and it came back. There was a new release, so I upgraded to it.

To follow up on my original post.
It's not happened again. Solid ever since the one incident.
I've also kept up to date with the dailys which means I've restarted often. So we shall see as the releases settle.

After upgrading to the final 2.5.0, all was well, but then I had a crash overnight.
Crashlogs attached.

That one doesn't look familiar to me...

What kind of features do you have enabled on there?

I don't see any exact matches on the code path there but it appears to be something working with raw IP sockets. Do you maybe have NAT+Proxy reflection enabled?

tomahhunt · Feb 19, 2021, 5:48 PM

@jimp I would say my setup is pretty vanilla.
Extra pakages installed are:

acme
bandiwdthd
iperf
openvpn-client-export
pfBlockerNG-devel

But pfblocker/iperf is disabled and acme not in use.

No NAT rules in use.

The only oddity is that it runs inside proxmox.
