I recently learned about accessing computers remotely using ssh. I have been having some fun with this connecting my mac with my gf's mac. I tried doing to same thing with a machine I had running Windows XP, but there were some goofy firewall settings that I couldn't get rid of for the life of me. So I installed Debian on the machine instead. I am completely new to Linux. I had a feeling that this might be easier with Linux than Windows, but I still can't make an ssh connection to my computer (both directions mac to Debian and Debian to mac don't work). I am not sure what the problem is since I can connect my macs together without any trouble. Any ideas? Are there some settings I need to change on my Linux machine to make it accept ssh connections? I have a feeling this whole process is sensitive to how my machines are connected to the network. For instance, when both the macs are connected to the same university wireless network, I can connect. If I am connected through a router and the other mac is connected to the university wireless, I can't. If we are both connected through the same router, we can connect. My PC doesn't have a wireless card, so it connects directly to the wall. Any help would be greatly appreciated!!!
