pfBlocker not logging after 2.5.2 pfSense upgrade

@nickd-0 said in pfBlocker not logging after 2.5.2 pfSense upgrade:
@cefleet looks like unbound was regressed from 1.13.x to 1.12.x in 2.5.2 due to some other issues... likely related? although IDK when 1.13.x was added to the main tree. Maybe a configuration option available in 1.13.x but not in 1.12.x is borking the logging?

oops .. very interesting. It seems a possible cause.

Looks like mine is logging only HTTP and not HTTPS as well.
I have the same problems. Blocking works afer reload, but don't log anymore.
-
I changed from Unbound mode to Unbound Python mode and that has seemed to have fixed things. I thought I did this the other day and it did not work. In any case, it appears to be working now. Thanks for everyone's input.
-
@cefleet Please monitor your disk usage as python mode on 21.05/2.5.2 has a an issue on some systems with slowly consuming all diskspace. The key issue is that no files/logfiles report a size / diskusage that accounts for the space usage - they remain sized like before. So you cannot locate the file/problem that fills the filesystem.
This leads to a situation where the filesystem is full, and you need to stop/start pfBlockerNG completely or reboot pfSense to regain your filesystem space.
-
@keyser Thanks for the heads up. I will keep an eye on the disk usage. So far everything looks good.

Thank you very much for the hint. I can confirm, that it is working for me with Unbound Python and enabling Python in pfBlocker DNBL.
-
@dotsch Same here, no issues with the python module and logging.
-
Ok so i also enabled Python Unbound mode and actually the logs are working again. I'll monitor in the coming days the disk occupation
-
Same story for me. Upgraded on the 15th (as clearly visible in the pictures below). Next to not logging of DNSBL there also seems to be a memory leak, unsure if related.
Is it possible to switch to python unbound with DHCP registration? As it still says "Python DNSBL mode is not compatable with the DNS Resolver DHCP Registration option (Unbound will Crash)!" in the information for selecting python unbound.
-
I have faced similar issue, DNSBL stopped blocking after 2.5.2 upgrade. I reinstalled pfsense but it didn't work. Later I changed mode to python unbound and it started working. However post this upgrade, my CPU and memory utilization is very high, earlier I had large list of IP and DNSBL but after this upgrade i cant enable all the list. I am running with only few list b of IP and DNSBL but after this upgrade i cant enable all the list. I am running with only few list but memory is still high. ut memory is still high. Is there any solution for this.

What is your CPU doing ?
See here Diagnostics > System Activity
Or better : console or SSH access, option 8 and entertopSee here for more info.

Well ?
Who is this : ntopng ? I don't know what it is. Is it useful ? It's going at light speed (132 % CPU usage !?!). For me, that alarming. What if that "ntopng" is doing a lot of DNS requests ? That would explain something.
You stopped it ? -
Yes I stopped it. CPU utilization is normal but Memory utilization is still high.
-
Use top again.
It shows the memory usage per process also.
Who is the winner ? -
Isn't high memory usage the nature of the Beastie anyway (file caching)?
I figure I paid for 100% of the memory and CPU and as long as I'm not running out, that's good ROI. -
One thing I noticed post 2.5.2 upgrade is that most clients are loosing internet connection for a while and connects back. I have observed this on few WLAN clients (mobile, tablets), they shows no connectivity . I thought it might be issue with AP (Unifi). I tried rebooting APs but issue still persists. I also check on few LAN clients and they also had similar issue. I have removed pfblocker and the issue didn't appear again. Today I have installed pfblocker again with unbound mode and few feeds. As of now all clients are stable and I am monitoring devices.
Unbound and Snort has major memory utilization.

I have
55688 unbound 2 20 0 105M 82M kqread 1 2:57 0.00% unboundThe difference is probably tour DNSBL usage (pfBlockerNG).
Still, these values are ok.
Btw : i'm not trying to block "everybody", as many and/or huge DNSBL/IP feeds do impact the system.
I'm just using the minimal :
-
Using the latest pfBlockerNG-devel, IP stats won't work unless using auto rules. If using only the "Alias" actions, i.e. custom rules, the package is not able to keep track of the rule matches. I imagine this is the intended behavior.
Note: I've only tested on 21.05.
-
@marcos-ng From the under Action it says :
Note: When manually creating 'Alias' type firewall rules, Prefix the Firewall rule Description with pfb_ . This will ensure that that Dashboard widget reports those statistics correctly. Do not prefix with (pfB_) as those Rules will be auto-removed by package when 'Auto' rules are defined.
