Just a note that nmap can be used by non root users for the simpler TCP
and UDP scans that don't create funky invalid packets or screw around
with the TCP protocol (which are used for XMAS scans, SYN scans, etc.).
These scans are more easily detected by IDS because they just look like
connection attempts; they're not very sneaky.
