something changed, but i dont really know if it is good ^^
WEll i typed this ifconfig "actions"
sit0 has an ip now.
I wanted to ping the server (192.168.100.100) and there was an reaction. but after this i couldnt type anything. even "exit" didnt work anymore...
btw, i didnt really get, what you mean with this "DNS" issues
EDIT: I restarted the computer and the ips have disappeared...
EDIT Numter 2:
If this an eth0 network; my brother has eth0, my father has it... how will i be able to connect with an sit0 network-code?!
