This was originaly posted as a hint a few days ago but never got published so I'm putting it up here. I believe it is important that the LittleSnitch users be warned about this.Little Snitch Clip Art
I decided my original technic was not enough and came up with a php shell script to manage the LittleSnitch daemon via the terminal. This is how SnitchCTL was born. It allows to start, stop and restart the daemon as well as use the UI Script to allow or deny a connection. It also allows to add basic allow/deny all rules to the configuration. The script is available here. I have also set up a page for the script. The source is available from the site.

Disclaimer :
This script has been tested with Mac OS 10.4.2 and LittleSnitch builds 212 (1.2b3), 218 (1.2b5), 226 (1.2). Ellie mae encompass for mac. Tests have shown that running this script under 10.3.9 is bad idea! Running this script poses a potential security risk! This script is provided 'as is', I am not responsible of any damages that could occur from using it. If you use it, you assume what you do it with and what ever happens to you!
While creating this script I discovered that LittleSnitch was really not as secured as it should/appears to be. Fracai has posted a great warning call on the LittleSnitch mailinglist. Here's a snippet:
LittleSnitch is not currently secure. 'killall LittleSnitchDaemon' will allow any app to 'phone home' without being detected by LittleSnitch Properly securing LittleSnitch would involve running the daemon and all LittleSnitch components as the root user or as an independent LittleSnitch user. [..] The main point to take away from this is that as it is currently implemented, LittleSnitch is not secure. A malicious app need not sneak new rules in to the configuration when the communication block is not effective.
The mailinglist post is available here.
Yes you've read that properly. The LittleSnitch daemon runs in user space! This means any malicious application can stop the daemon, sent the data and then start the daemon back up with very little change that the user ever knows about it! LittleSnitch doesn't output to the system/console log so there is no logs of what's been going on.I suggest you read the site I've put up and the mailing list post by Fracai if you want to know more about this issue. I have also created a thread in the forums if you have any questions or comments. Final fantasy x x 2 remaster via wine steam for mac.
