@quikkie @Viss I tried that one myself and I like the idea but it was always more of a hassle to manage than I was willing to deal with.
@cR0w @Viss rough edges? Yeah, later versions are better but not littlesnitch great.
@Viss @cR0w Wow! Just wow! I thought OpenSnitch was a long term thing for me now that I switched.
@Viss @cR0w Didn't know it was available for Linux. I'll try it out on one of my linux test machines, never felt like trying it on my Macs, didn't have a spare one to test things with.
@CliffsEsport @cR0w i used it on every mac. it was amazing. super helpful to figure out what bullshit is phoning home to where. gives you popups when shit tries to reverse shell etc
@Viss  This looks really cool!

@Viss @catsalad @cR0w wtf? Using this on mac since I don’t know when and now on Linux as well?

Edit: fix typo

@sothawo @catsalad @cR0w yeah i guess the linux port is pretty new
@Viss @cR0w Have you used OpenSnitch in the past on Linux? If so I'd be curious to hear your impressions on how this LittleSnitch port compares.
@kyle @cR0w its been a long time. i remember opensnitch being pretty good, ill hafta install this one and see how it fares. i trust obdev.at tho - littlesnitch was glorious. i used it on every mac
@Viss @kyle @cR0w I’m going to try it as well; I ran opensnitch for a while but it was painfully disruptive so I shut it off.
@Viss @kyle @cR0w I too would be interested in a comparison to OpenSnitch. I'm currently usisng OpenSnitch and am curious of it's worth switching.
