One thing after the next. Man I tell ya.
Well my network has 2 computers (XP and Fedora) connected to a router. Fedora's ip is 192.168.1.101 and XP is x.x.x.100. When I set the network up I remember specifically setting Fedora at x.x.x.100 and XP at x.x.x.101.

After I realized I was scanning my computer and not XP, I brodcast pinged my network and it only showed my router 192.168.1.1 and me(Fedora). There is nothing wrong with the connection to XP. So i ping XP and it started scrolling a bunch of blank lines. I hit ctrl C and it says: 3 packets transmitted, 0 received, 100% packet loss, time 1999ms.
Weird. I try again and: 15 packets transmitted, 0 received, 100% packet loss, time 14008ms. <------confusion point.

Apparently XP isn't there even though I physically got on XP and looked up its ip and I floated around on the internet a little.
XP is running blackice. If that helps.
I also thought that I might need something for Fedora and XP to communicate. But even being the case, shouldn't I still be able to scan or ping XP with Fedora?
