Hi there, I've got a few computers on my LAN, among which 2 mac minis. I usually ssh from one (call it mac1) to the other (mac2), or share screens. But inexplicably, some days the connection is impossible to establish. I can't ssh, not even ping (mac2 is still visible in the "shared" list on finder windows, though). I use IP addresses when ssh'ing or pinging. Other devices on the same LAN (linux laptop, MacBook pro, iphone) ssh into mac2 absolutely fine. Also, mac1 can ssh into those other computers without a problem. Sometimes it works, then I can't connect any more, then it comes back a few hours later. All randomly AFAICT. It may well be the router (http://www.zoobab.com/bbox2) but that's where I'm lacking skills to find out if it is, or if it's some strange OSX thing. Thanks for any help.
