ALIX 2c3 and pfsense (LEDs)

jimp

A developer with an Alix wants flashing LEDs enough to put the new version in.

That did it.

Must. Have. Blinkenlights. :o

Yea!
Doh!

Yeah the patch didn't apply cleanly, I'm working on it still :)

jimp

Ok, I fixed the patch and committed again. Not sure when the next snapshot will be due.

I've got one building on my own builder, too, so if mine finishes first (unlikely) I'll test it on my ALIX and report what I found.

jimp,

Thank you very much!

Do you know how I can get them tide up one for networking and one for HDD led….

Must see blinking leds :o

Not sure about that part yet. I have a new image built, but I haven't tried it yet, I'm chasing a different problem down at the moment.

jimp

Well I'm still not sure how to assign the LEDs various tasks, but I can tell you the patch worked

My middle light is blinking, not sure what that is indicating, but it's blinking… which is better than off :-)

jimp

Various cool things to do:

On

echo 1 > /dev/led/led3

Off

echo 0 > /dev/led/led3

Fast blink

echo f > /dev/led/led3

Slow blink

echo f9 > /dev/led/led3

(Works with any number from 1-9 or blank)

Morse code

echo "m…---..." > /dev/led/led3

I use led3 in this example but it works with 1-3.

Still not sure how I'll tie them to things or make them generally useful, but I'm open to ideas. (I don't know if they can be tied to network activity or not, doesn't look like it, but we'll see)

jimp

Looks like a new embedded snapshot just happened, it should have this.

Jimp,

Maybe you can add what dotdash did which was add RSW's blinkled-…

That would work! :)

If I can get a link to the source, perhaps. I couldn't find it with a quick Google search.

serialdie

jimp,

I PM dotdash to see if he shares the source code…
Lets see how it goes.

TIA!

jimp

I found it here on the forum:
http://forum.pfsense.org/index.php/topic,3454.msg21194.html#msg21194

I'll keep experimenting.

jimp

It still compiles and runs for me, I've got LED2 showing my WAN activity and LED3 showing my ath0 activity.

It would still need some kind of a user interface to configure, I'll have to see if I can whip something up.

serialdie

jimp,

Thats great!!!!

Lets see how it works out!

Thanks!

dotdash

Just grabbed a new image and loaded it on an Alix. The /dev/led devices are there and working- thank you Jim. I couldn't find blinkled, but that may not be in the build yet. Anyway, here are my two cents as to some handy options for the LEDs.

Use an LED as a 'ready' or 'armed' light. Helpful when you are working with a remote end user. I did something like this by putting a script to light LED2 in /usr/local/etc/rc.d/ and appending a command to turn it off in /etc/rc.shutdown (kind of a hack).
Activity for an interface. RSW's blinkled works well for this eg- blinkled -i ath0 -l /dev/led/led3
VPN linkup. I'd like to be able to do this with IPSec (like on a PIX or something), but I'm not sure how to go about it. Just putting it out there.
Blink an LED on active alert. I believe this was done with WRAPs at some point, but I never had a WRAP to test with.
A simple gui would be cool, enumerate the led devices and provide a menu with some stock options or a custom script.
These are only suggestions, I'm happy just to have the led devices now. I can do more testing on this if you need it.

jimp

dotdash,

Good to hear it's working for you, too. I have locally compiled blinkled and have it working, though it will take a little time before I can get any kind of gui going. blinkled is not currently in pfSense anywhere, but if I can get it working with a UI I'm sure it will find its way in.

I doubt it would be a good candidate for a change that would make it into 1.2.3, but 2.0 may only be a couple months away at this point, depending on progress.

I think LED2 already does blink on an active alert, but a slow blink. I'd like something more like you see with: echo 'm…---...' > /dev/led/led3

As long as I know blinkled works for people and doesn't cause any undue load issues, I'll carry on. It seems to work fine on my ALIX and I have yet to see top say it uses more than 0.00% cpu :)

@jimp:

Ah, yes it does. I probably should have tested that first. Enabling ssh is an easy way to trigger an alert.
This appears to be defined in /etc/inc/notices.inc:
function close_notice($id) {
global $notice_path;
require_once("util.inc");
/* soekris /
if(file_exists("/dev/led/error"))
exec("/bin/echo 0 > /dev/led/error");
/ wrap */
if(file_exists("/dev/led/led2"))
exec("/bin/echo 0 > /dev/led/led2");
$ids = array();
if(!$notices = get_notices()) return;
if($id == "all") {
unlink_if_exists($notice_path);
return;
}
foreach(array_keys($notices) as $time) {

(Oops, that's the off stanza. The on is sending /bin/echo f5 > /dev/led/led2)

Just verified /dev/led/error on a net5501 blinks the same as the Alix on an echo f5, so I'm not sure why the Soekris just gets a solid light and the Alix gets a blink.

I try to compile it my self in my pfsense box and it error out with a bunch of errors….

Does that FreeBSD box have all of the FreeBSD sources and includes present?

Seems weird that it wouldn't work. I compiled it from my pfSense builder box (RELENG_7_2) and it worked fine.
