Traffic Shaping / Floating bandwidth value for shaper (bufferbloat checker)
« on: September 27, 2017, 09:14:28 pm »
If we are using traffic shaper to eliminate bufferbloat, then we need to limit bandwidth as well, 80-95% according to some sources, but here comes another problem, sometimes this limit needs to be adjusted depending on ISP channel load or day of time or anything else or you just do not to waste those bandwidth percents you paid for, so the main idea is to use scripting to change bandwidth value depending on ping value. We know current limit and current load, we can ping ISP gateway every n seconds, so actually we can collect statistics of current link saturation and change bandwidth value according to it, ex. from 50% to 100%.
Is it a good idea? What cons do you see?

I got it today, on the latest snapshot
2.4.0-BETA (amd64)
built on Fri Jun 23 14:39:50 CDT 2017
FreeBSD 11.0-RELEASE-p10
I did not have traps for at least 5 months before that day.

Unfortunately I don't have swap enabled currently.
Any changes last days that can cause this? Or it's hardware?

Packages / Add freeipmi to package reprository?
« on: January 29, 2017, 01:09:07 am »
Is it possible to add freeipmi to pfSense package reprository or there are some compatibility issues?

I just leave it here.
Edited: Wrong link  >:(

Possible pros:
Please add some, if you know any

I understand the risks and do not wait any support  :D
If you run ping command without 'count' option via GUI, GUI will never respond again returning "504 Gateway Time-out", untill you manually kill ping via SSH or restart PHP-FPM via console.
Is it possible to implement some "abort command" button in the GUI instead of indefinitely waiting for an answer?

2.4 Development Snapshots / sysctl boot message: empty numeric value
« on: January 05, 2017, 09:37:05 am »
I think it came after adding some system tunables in the GUI and then removing them after further testing. Now I receive error message during boot, how can i diagnose what is wrong?

2.4 Development Snapshots / "ufs in RAM" on dashboard, when using ZFS
« on: November 10, 2016, 10:29:34 pm »
Is it OK?
Should it be reported as cosmetic bug or it's really UFS? Sorry for stupid question...

2.4 Development Snapshots / UEFI boot problem on real hardware.

"Launch UEFI shell from device" shows zero compatible devices in list.

Traffic Shaping / Queue length in LAN shaper
« on: September 26, 2016, 12:02:21 pm »
Pfsense 2.3.2
I have qp2p queue on LAN interface with queue limit of 50000 packets, but if I open Queue Status page, then it shows under heavy load that limit is 5000 and drops packets over 5000 limit, if I put 10000 (less then 50000) limit it behaves like it's 100, shows 10000 on Queue Status page and drops everything above 100. What am I doing wrong?

General Questions / PowerD power modes.
« on: September 24, 2016, 05:27:48 am »
The question is how PowerD detects current power mode (AC/BAttery/Unknown)? I ask because it looks like it does not detect for me anything and just stuck at "Unknown", but I'd like to use "AC" and "Battery" modes.

When I open roadmap for 2.3.1 it shows 1 issue open, when I click it, than it shows no issues no data to display, for me it's since Friday, roadmap shows one hidden issue. Is it OK?

Installation and Upgrades / Rescue config.xml from memstick not working
« on: December 23, 2015, 12:58:22 am »
I can boot and install pfsense from memory stick using amd64 raw image, but if I select rescue config.xml and on next step I select disk, then installer just closes, it gives console message about failed installation and pfsense continiues to boot.

IPsec / Wake On LAN (WOL) with magic packet over IPSEC VPN
« on: September 04, 2015, 01:24:15 am »
I have configured IPSEC with strongswan between my pfsense box and android client, all works fine except sending WOL packets into LAN. Ping works, and I have created rules for ICMP and UDP traffic to bypass magic packets. Once it worked and never again, what am I doing wrong?
BTW I don't see any blocked packets in firewall log. And I can wake up the LAN PC from pfsense WOL service
