Hello everyone!!! I got hping3 compliled on my system, but when I try something as simple as a scan (testing), I get an error stating that the operation is not permitted. I tried with sudo and then su'ed with the same result. I'm currently running ubuntu 2.6.31-14. GCC 4.4 and tcl 8.4 and 8.5. Thank you in advance!!! chrisj chrisj@chrisj:~$ sudo hping3 --scan 1-2000 -S 192.168.2.1 [sudo] password for chrisj: Scanning 192.168.2.1 (192.168.2.1), port 1-2000 2000 ports to scan, use -V to see all the replies +----+-----------+---------+---+-----+-----+-----+ |port| serv name | flags |ttl| id | win | len | +----+-----------+---------+---+-----+-----+-----+ [send_ip] sendto: Operation not permitted
