Enable HTTPS Filtering: Chain ProxHTTPSProxyMII to Privoxy (OS X Tutorial)

[Faxopita]

View Privoxy Status in OS X Menu Bar

1. In all scripts, replace "Thunderbolt Ethernet" by Wi-Fi if necessary. Other alternative: complete with configuring other device ports at the same time.
2. I did not find any better solution than activating Privoxy logging. If issues in detecting Privoxy status, unable debug modes 512, 4096, 8192 or try any one of those.
3. It might be wise to empty the log file once in a while… For example, at system startup with a cron job:
   
   Code:
   

   @reboot echo $(grep "toggle?\(mini=y&\)\?set=\(enable\|disable\)" /private/var/log/privoxy/logfile.log | tail -1) > /private/var/log/privoxy/logfile.log
   (command to empty the log file but the latest Privoxy status)
   
   Note: you might need to claim the ownership of the log file if you choose to add the cron job as a regular user. Make sure Privoxy has write access to the log file too! Otherwise, it will crash.
   

Install BitBar via Homebrew Cask: brew cask install bitbar

Amend [script folder] in those scripts:

• Privoxy_Status.5s.sh (menu bar item refreshed every 5 sec.)
• HTTPS_Port_Status.1m.sh (menu bar item refreshed every one min.)
  

Both located inside your BitBar folder.

Caution with Script `Privoxy_Status.sh`

If you're not in the habit of clearing Privoxy's logfile once in a while—you may want to keep it for later examination—I suggest you “rotate” it daily in order to reduce CPU usage every time the command grep is called—every x seconds. Highly recommended since using such a command-line utility cyclically on a logfile of 100's of MB (past a million entries) can have a serious impact on your CPU during a few seconds. Not good if you're on battery then!

In my case, I decided to have Privoxy's logfile content flushed out daily to some other file located inside the userland part of the system; you can create a new cron job—`crontab -e` in Terminal—and add this line:

Code:

0 20 * * * cat /private/var/log/privoxy/logfile.log >> /usr/local/var/log/Privoxy/logfile.bak && echo $(grep "toggle?\(mini=y&\)\?set=\(enable\|disable\)" /private/var/log/privoxy/logfile.log | tail -1) > /private/var/log/privoxy/logfile.log

If you just want to clear Privoxy's logfile content at 8 p.m. daily:

Code:

0 20 * * * echo $(grep "toggle?\(mini=y&\)\?set=\(enable\|disable\)" /private/var/log/privoxy/logfile.log | tail -1) > /private/var/log/privoxy/logfile.log

(if every hour, replace `20` by `*`)

Same job but at reboot time only:

Code:

@reboot    echo $(grep "toggle?\(mini=y&\)\?set=\(enable\|disable\)" /private/var/log/privoxy/logfile.log | tail -1) > /private/var/log/privoxy/logfile.log

To list your cron jobs: `contrab -l`.
