@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.
