ALIX 2c3 and pfsense (LEDs)
-
i was waiting for this since the day i bought the alix, is it possible to configure the led to blink even faster or lets say a way to configure the on and off period, i want it to blick link the leds on a switch or a router, which is faster.

You would have to look at the source of the blinkled program for that, which I didn't write. I don't think it can be used as a realtime indicator like a real switch port. It only polls periodically and flashes if it sees activity within a specific timeframe, if I recall correctly.
-
how about if it was used for the correct purpose of the LED being in the alix in the first place, think of it as a computer, LED1 could be power which it already is, LED2 as processor indicator and LED3 as HDD or CF read/write as the LEDs on the network adapters are enough of LEDs already blinking as for me they face the wall and there not being any way to turn them off as its directly plugged to the network card chip
-
It being a customizable device, there is no real "correct purpose" for the LEDs, they can be whatever someone programs them to be. Personally, I like LED1 to be power and alerts, and LED2/3 to be network activity.
If someone wants to come along and write a program that will flash the LEDs based on other types of activity, it would be more than welcome.

In 2.0 I have an LED library that makes it easy to do some handy things, but I don't think it's going to make it into 1.2.x. For example, I have it blink "sos" in morse code on LED1 when there is an alert. That part may make it into 1.2.3 if I get some time to work out a patch (should be easy I just need to take the time to reflash my alix as 1.2.3 and test it first)
If something is going to use the LEDs on 1.2.3, it will need to be something that can be made into a package, like I'm working on with blinkled.
The problem is that the system itself can't be told to trigger the LEDs on, for example, disk activity. Some program will have to be constantly running and polling for disk activity and then flash the LED when it is seen.

Anyone do anything cool with the LEDs?
-
Not with PFSense, but with a WAN Emulator I have the second LED turn on when emulation is on. Just a visual reminder.
Maybe PFSense could have it turn on if certain events are true like if OpenVPN connection is established, if a certain firewall rule is tripped or if a critical service stops running like ospfd or snort?Personally I use pfsend under kvm, so I don't run it on ALIX. I don't know if you guys keep it on your desks where you can easily look at it.

I know it's been a while but I do have some updates:
#1: I'm going to be adding some LED stuff to 2.0. Stuff that won't/can't make it into 1.2.3 because it will have to be in system files and not in a package.
#2: I did just add a blinkled package that will work on the 1.2.3-RC nanobsd images. It works for me, so give it a try. After installing the package, go to Interfaces -> Assign LEDs. Should be self-explanatory from there.
Is there any way to obtain de source code of blinkled ? i would like to try to adapt this code for the leds of a firebox II panel ?
