Okay, question: What do these keys do (in exactly that order)?
Ctrl+t, Ctrl+r, 2, 5, 4, Return
Answer (you are not supposed to know this ;-) ): It opens up a terminal
emulator (Ctrl+t), starts reverse-i-search in bash (Ctrl+r), searchs for
the last command with "254" in it which happens to be "sudo ifconfig
eth0 192.168.178.254 up" and runs this command (Enter).
The result is that my ethernet device is brought up in an instance of a
second with an IP address of 192.168.178.254. I used this today to play
a little game against a buddy of mine in a pause.
He uses Windows (do you already know where this will go?). Start ->
Control Panel -> Network Devices -> Local Area Network ->
Properties -> TCP/IP -> Properties -> Set an IP address ->
192.168.178.5 -> OK (translated, don't know if that is what it is
actually in an English version of Windows)... Wait 20 seconds or so...
start the game... click away the warnings of the personal firewall...
restart the game... try to connect to the other computer... does not
work... start the server on the windows box so I can connect to it...
does not work... try to ping my computer from his... does not work...
try to ping his computer from mine... does not work... figure out which
one has to reboot as this has always worked... "Windows because
it is always Windows' fault"... restart the windows box... try to ping
my computer from his... miraculously DOES work...
