Suppress arpwatch flip flop emails for Bonjour Sleep Proxy

dbwiddis

EDIT: This has been fixed in release 0.2.0_2. Do not do the hacks below, just update your arpwatch package!

It is posted in my original post. Look in /usr/local/pkg/arpwatch.inc for the line

if (false !== $message) {

And replace it with the below (substitute your own device MAC addresses):

$flipflop='flip flop';
$tv1='c8:69:cd:00:00:00';
$tv2='e0:89:7e:00:00:00';
$tv3='1c:1a:c0:00:00:00';
  
if ((false !== $message) and (
  (false === strpos($message, $flipflop)) or
  ( (false === strpos($message, $tv1)) and
    (false === strpos($message, $tv2)) and
    (false === strpos($message, $tv3)) ))) {

@dbwiddis Thx !

Actually, I realized I had an error and reversed the order of the arguments in the strpos. I've corrected my posts. What I had suppressed all messages, oops :)

@dbwiddis
I was about to say - it does not work :)

Thx for correction.
We will see now!

So far in last 3-4 hours it seem to be holding water :)
Did you tested if it will stay if arpwatch reinstalled it will stay in place or not ?

I did just test and uninstall / reinstall arpwatch, and it wiped the script hack and the database. But it was easy to put back in.

I installed arpwatch 0.2.0_1 and see 'sometimes' still flip flop emails.

Odd...
Do you see it after upgrade ?

Since uninstall/reinstall replaced my custom fixes it wouldn't surprise me if an upgrade overwrote any modifications you've made. Just go re-edit the /usr/local/pkg/arpwatch.inc file, and in the arpwatch config hit "save" to copy from there to /usr/local/arpwatch/sendmail_proxy.php. You can use the file viewer to confirm whether the modifications are there.

I have only seen one other "flip flop" email for a different device (my Orbi mesh router, that has a hidden mac/wifi address for its backhaul network).

I did not did Save configuration step, hope it's good now.
Confirmed now the changes were saved to /usr/local/arpwatch/sendmail_proxy.php

Thx

@viktor_g Fantastic! I had thought about doing something like that but had no clue where to start.

dbwiddis

So now that @viktor_g showed us the right way to make a permanent fix, I've implemented that change as well as my own tweak to it, and another request to not wipe the database on uninstall/upgrade. I love this community. :)

@dbwiddis very cool !

What's ETA for this to be merged ?

Dunno, @viktor_g made a pull request that someone has to review, and I made a pull request to his branch that he has to review (and testing indicates might be broken...) and then even when they are all accepted they need to release 0.2.0_2.

So.... don't hold your breath, but if you're comfortable hacking a bit, you can get a jump on the official release :)

Finally figured out my error.... 0 can be either false or true depending on which logical operator you use.

PR was merged and I installed update, hope it will be great !

Thank YOU SO MUCH ! ;)

In office we have a lot of appleTV and w/o this suppressing mail/pushover would be filled in a day…

Good luck in coding!
