Devic polling

Leoandru · Feb 15, 2006, 1:12 AM

I enabled device polling from the advance menu of the web gui. When I checked sysctl -a I get kern.polling.enable: 0
how do I know if polling is really working? I have 3 Nics in my pfSense box. 2 use dc driver and 1 use xl driver so I know all support kernel polling.

ifconfig -a and look for the polling flag.

Leoandru · Feb 15, 2006, 2:10 AM

still dont think its working. I did ifconfig -a didnt see any polling flags whats interesting is what I did next. I enabled kernel polling at shell but I didnt see the polling flag instead I saw it under options for the interfaces. What does this mean?

ifconfig -a

Did you try rebooting after changing it? Perhaps its a reboot bug.

Leoandru · Feb 15, 2006, 2:21 AM

yeah rebooted twice, still no polling flags on the interfaces. Only when kern.polling.enable is enabled I see polling under options as per my last post.

Im using 1.0-BETA1-TESTING-SNAPSHOT-2-8-06

sullrich · Feb 15, 2006, 2:23 AM

kern.polling.enable
Legacy MIB, that was used to enable or disable polling globally.
Currently if set to 1, polling is enabled on all capable inter-
faces. If set to 0, polling is disabled on all interfaces.

I'll check it out, its possible that I just left out that interface type from the supported list.

Leoandru · Feb 15, 2006, 2:33 AM

cool. 8)

in the mean time I'll just set the option in sysctl.conf since I want to manipulate other polling options as well.

Im running the new testing snapshot TESTING-SNAPSHOT-02-15-06. I removed the kern.polling.enable variable from my /etc/sysctl.conf file to see if the web gui option for enabling and disabling polling would work. Well the option didn't work and polling seem to be enabled by default on reboot, even after manually disabling it at shell.

Okay, hopefully its fixed now. If you like, update pfsense-utils.inc to http://cvs.pfsense.com/cgi-bin/cvsweb.cgi/~checkout~/pfSense/etc/inc/pfsense-utils.inc?rev=1.316.2.63;content-type=text%2Fplain;only_with_tag=RELENG_1 to test.

:D

Thanks, thats fix it. Enabling and disabling polling with the web gui now works.
