2100 LED question

[SteveITS]

@JonathanLee The Arm devices don’t/can’t power themselves off. There is a thread somewhere but basically the only way was to turn off the LED before shutdown is finished, and they didn’t want to do that.

@SteveITS

Thanks for the great information and link to the bash script that worked great!!!

Check it out green LED

Thank you, my wife is happy too no more blinks that turns off too now when needed

[JonathanLee]

Has anyone ever linked a LED to turn on when an access control list establishes a state.

Example of what I want to occur.... Drifting off into dream land ....

It's 11pm and someone turns on a gaming system, you know this individual has a test or maybe a soccer game tomorrow, all the sudden your firewall'a state established LED turn on and glows red.

I sprang from my bed to see what was the matter. Away to the TV I flew like a flash, tore open the door, and went with dash. When, what to my wondering eyes should appear, the little one again with game controller in hand. Now little one you stand with a solemn face... go to bed ! Go to bed! Go back to bed now!"

It would have one green and one red led holiday colors.

(link to xbox ip group rule...?)

You could in theory add it to any rule you want by way of tracking id.

Anything can be coded given sufficient motivation.

I am a computer science student right now, I have learned some Python, Assembly, and Java. I knew Basic as a kid for the Tandy 102. However, this programming language I have not learned yet, the constant $ is confusing. I think it is C. I really can not wait to take a class in this language. I even learned some bash scripting. It is C++ or C# right? We even did some PIC programming in mechatronics class but nothing looks like this language.

The use of $ all the time makes me think of Microsofts Xenix operating system.

[stephenw10]

The script linked above? It's a shell script; so like a bash script except not bash, it uses the default bsd shell. https://man.freebsd.org/cgi/man.cgi?query=sh

Thanks $ "Expands to the positional parameters" There has got to be get this to work with a tracking id for an ACL

I did not know it could do solid red, pretty cool!!!

Well changing the number in that script is easy but adding that script to the acl is going to be harder. I think I can just add in the command to change to red to the tracking id somehow, again within the open source code finding that section of code is harder.

[stephenw10]

You could run pfctl -vvss to check for open states using the ruleID and use that to trigger the LED via a script run on a cronjob.

LOL - you said Microsoft Xenix,

Radio Shack back in the day ran this on the Model II (1979ish)
the computer is long gone, but I have a set of 8" install floppies and manuals around somewhere if you need them ;-)

Later iterations of the Radio Shack (Tandy) line after they changed from the Motorola processor and switched to Intel (IBM PC Clone), could ran SCO Unix - I pulled the manual from the shelf you want me to look something up for you

Or if you want something more "original" we could go back to this

From this core are also derived
Microsoft's OS/2 / Windows
and
Digital Equipment Corp (DEC) pdp and VAX based systems
the core systems in each remarkable close to the core unix
and
Apple's OS versions

what a blast - those day

@jrey EPIC!!! I have a Xenix book too,

I have a VM that runs it so could play with it. I wanted it as a kid in the 1990s so bad. I had Dos 3.11 back in the day. I learned that the mail application is like Alpine

https://unix.stackexchange.com/questions/366048/xenix-sco-v-running-in-contemporary-machines-as-vms

Check out part one and two that is my addition to how to run it in virtual box step by step, no clue why someone marked it -1 for me :( I bet it is someone that hated that os or something.

[JonathanLee]

@stephenw10

I got the output with the a rule using that command YEAH!!!

Cool I have and old DEC PDP emulator that I fire up from time to time just to perform a memory test (that is my memory - how much can I remember)

have fun with the lights. (like your "night before" re-wording) you could also just create some time based rules to block the late night gamer.. But then again the lights do sound like they are way more fun.

[JonathanLee]

@jrey I like the lights because even with the offline timers he turns it on to play what's already installed on it. Once at 3am till 5am on his last soccer game, he looked like a zombie the next day.

[JonathanLee]

I got my rule id it is 43

However running

switch -R does not work for some reason

It would be these rules to show stats only

In linux you can just display specific information I wonder how to pluck that out in freebsd

pfctl -vvsr

I will figure it out I just need all the rules that are in use for GAME_IP_GROUP

YEAHHHH use them with pfctl -vvss | grep ', rule ... and we should be good to make a script use a if clause if !null it should work and make a cron for it

[JonathanLee]

pfctl -vvss | grep ', rule 43'

[JonathanLee]

I am going to use this as a string entry and check to see if it is null if not turn the led on.

Simple enough in theory.

[JonathanLee]

Something maybe like this

#!/bin/sh
pfctl -vvss | grep ', rule 79' >/dev/null
res=$?

if [ $res = 0 ]; then
  sysctl -q dev.gpio.2.led.2.pwm=1
  gpioctl -f /dev/gpioc2 6 duty 1 >/dev/null
fi


Or...

#!/bin/sh

str="$(pfctl -vvss | grep ', rule 79')"

if [ -z "$str" ]; then
  sysctl -q dev.gpio.2.led.2.pwm=1
  gpioctl -f /dev/gpioc2 6 duty 1 >/dev/null
fi

[stephenw10]

The problem there is that the rule number an change if you add or remove rules. I was hoping you might be able to see tags on rules in the states but I don't see a way to do that. Yet...

[JonathanLee]

@stephenw10 It works if you don't adjust the rules I have it going now.
