all those who have problem downloading files of nitdroid installation through nitdroid in xterminal.. here is an alternate..
1. Download these files manually on pc:
http://downloads.nitdroid.com/nitins...nal1_armel.deb
http://downloads.nitdroid.com/nitins...-Popov.tar.bz2

2. then.. reboot n900 and select maemo on startup if it shows and if it doesnt it will go to maemo directly..

3. dont run anything.. directly connect the phone to pc with usb cable..

4. open the Nokia N900 drive.. and open .nitdroid

5. place the both downloaded files as they are(dont extract) in .nitdroid

6. unplug the usb cable/ disconnect the phone from pc

the downloading big files process is done.. and now all you have to do is to continue with the step 4 of ammyt tutorial on page 1..

By this method i installed nitdroid easily on my N900 and no waiting for hours..
