udp_scan on Debian 4

Download & Setup:

lftp -c 'open -e "mget port-scan*" ftp.porcupine.org/pub/security'
tar zxvf port-scan.tar.gz
cd port-scan
make CFLAGS=-D_BSD_SOURCE

There will be some errors.

Then, run udp_scan on target:
./udp_scan 10.10.10.10 1-1024

Note: udp_scan also comes with the SATAN package (and its successors).
