GlowWorm FW Lite is a rule-based network security and monitoring application built on plugin-accessible framework.

Rules can be defined on the basis of a set of connection criteria include the addresses, ports, relevant endpoint and protocol. Additionally, rules can be restricted to a particular set of users, groups or applications, and the lifetime of a rule can be limited by the lifetime of that application or until the machine reboots.

Relative Network Names allow one to specify symbolic endpoint address like localhost, localnet or remotenet instead of having to "hard code" an ip more...

What's New

Version 1.5.3b4:
  • Added Growl notification support to Rule Actions.

I am running leopard 10.6 and loaded this program with the safe version. It crashed my macbook and the only way I could get going again was to restore from my time machine backup. I had been running little snitch previously on a older macbook without an issue and will go back to it. My only issue with little snitch is you have to take the time to work out whats safe or not.

If you've upgraded to 10.5 like I have, and your system is still OK, but GlowWorm is still in your process list in Activity Monitor, here is exactly what I did:

Open Activity Monitor
Quit the Glow Worm process (called glowwormd or something like that)
Then to uninstall,
Download GlowWorm FW Lite (from this page)
Mount the .dmg GlowWorm-1.5.3b4 (or whatever it is exactly) on your desktop and open it.
Right click (or Control-click on 'Installer')
Show Package Contents
Contents > Resources > Uninstaller
That should uninstall all GlowWorm FW related files without actually installing them first.

Restart to make sure that process isn't still running.
Good luck!

By the time I read "10.4 required, will not work on 10.5" I had laready pressed the install button. Froze my system, had to do a hard reset, then got blue screen with cursor. I have a second machine and was able to find forums that advised starting on safe-mode and unstalling. I suggest putting in bold letters at the very top of description WARNING: THIS APPLICATION WILL CRASH LEOPARD! DO NOT INSTALL IN LEOPARD. Yes it's free, but please be responsible and warn your users.

WARNING: This application can lock up your system as soon as it is installed.

Some time ago, I installed glowworm on OS X 10.4, didn't like it and uninstalled it. At least that is what I thought. I finally figured out it was still running on my system causing some strange errors. I noticed that it was still causing thousands of lines of errors in the console app. I then decided to reinstall the app, so I could use the official uninstaller that comes with the installer, hopefully ridding my computer of every trace of glowworm.

After I read the other commenters warning of system crashes, I thought to myself, "I will just install it, but never run it, so I can get the uninstaller." Big mistake! This thing automatically runs without even starting the app, immediately crashing you system badly.

I had to do a hard shut down, and the boot in safe mode (took a VERY LONG TIME to boot up) to run the uninstaller. After I did so, it was fine. The developer is crazy to think this thing runs on 10.5. IT DOES NOT RUN ON LEOPARD AT ALL!

Careful! This program hosed my Leopard mac. After installing and launching, immediately a few of my apps stopped responding and went into a ghost state in which they could not be force quit under any means (I've never seen anything like it before). A soft logout or restart stopped working too, so I did a hard reboot and my mac would not make it past a blue screen. Tried over and over again, couldn't even get to the login screen. I rebooted from my OSX DVD, opened the Terminal.app and looked for recently modified files in the /System directory. Guess what: the newest file was a GlowWorm kernel extension. I moved this out of the way (the only change I did), rebooted and my system now works perfectly again. This is program super flaky, I have NEVER had a program prevent my mac from booting before.

I realize that it's hard to maintain free software, but when it comes to kernel extensions, my tolerance for flakiness is very low. Use caution.

I just had the same thing happen to me with GlowWorm-1.5.3b4 on 10.5.2! Thankfully I had already read your post and removed the kext before force-restarting so I didn't have to go through safe mode. This program, while I'm sure it is good intentioned, needs some work.

Don't use 4.53 beta 2 under Leopard. Installed under leopard. system began to hang on startup. I had to boot into safemode and uninstall with their uninstaller found in /Libarary/Application Support.

Why does it try to connect to dm00042.lunarpages.com every time an unknown outward connection is made?

Thanx to the developer & users of this software for your informative reviews - i'm making the transition from Win PC to iMac & looking for a Mac FW comparable with Comodo, which i've been using on XP with great success. Being a total noob to Macs, i'm wearing myself out scouring the net for general info so i (hopefully) don't stuff up! I'm encouraged by the fact that this software allows users to make application-specific rules, as i'm not sufficiently au fait to make IP- & port-specific rules...my first challenge will probably be configuring my ADSL connection to at least get online!

Anyway, thanx again & cheers!
