nmap
 

Id like to run -sS without being su. Is this a matter of file permissions? How would I go about doing this?

Probably best to setup sudo but I think this is actually built in to it.

TCP Syn means that nmap has to use generate raw sockets. the only user who has access to the raw socket interface is root. thus you need root.

raw sockets:
as an example with ICMP.

[psyklops@MoBAP dl]$ sudo nmap -sS -p1-100 localhost.localdomain
sudo nmap -sS -p1-100 localhost.localdomain
Password:
psyklops is not in the sudoers file. This incident will be reported.
[psyklops@MoBAP dl]$

Im alittle confused on the format to allow me to run -sS without su'ing though. I cant make heads or tails of the sudoers man. Has anyone set up an sudoers files before. If so what would be the correct syntax?

Heres a copy of my sudoers file in case anyone else gets stuck. I had problems with the format even though its pretty straight forward. : P
