The comands are like
wlanctl-ng wlan0 lnxreq...
ifconfig wlan0 ...
route gw...

etc.

I put the lines in a file, name the ending .sh and mark it executable. When I try to run the script nothing happens. I have to copy the lines and paste them into the console, after switching to root.

By the way... How can I access another resource over the network?
