Penetration Testing: Re: faster scans? (nmap)

Re: faster scans? (nmap)

Thanks for the responses:
- The -PT option is great, if you know the host is
listening on that specific port, otherwise it's kinda of
useless. Remember a firewall is most likely sitting
infront intercepting these packets, if the IP does not
exist the firewalls going to drop (and not send a rst) the
packet. This gives us no information to work from heh.
- The -T Insane (5) -T Aggressive (4) Options don't
exactly help either, Insane gives up after 75 seconds if
no response is seen, (keep in mind a machine that may have
a service listening on port 23592, this would never get
picked up, nmap would quit after 75 seconds of scanning
[unless it hit this by random]) So that rules this option
out. Aggressive timed out in 300 seconds same deal as
before with Insane.
- strobe didn't seem to work any faster in this case, I
tried that as well.
*sigh* people need to not disable icmp echo reply :)
Any other suggestions? (Thanks to all of you who did
respond)
