portscan from the CLI

download, compile and install nmap (from www.insecure.org/nmap/), then do:

% nmap host.you.want.to.scan

nmap is absolutely the best port scanner available. don't settle for anything less. check out the man page ('man nmap')for all of the interesting options, or do 'nmap --help' for a quick synopsis.


can you walk me through the process....

upon ./configure

i got this:

creating cache ./config.cache
checking for gcc... no
checking for cc... cc
checking whether the C compiler (cc ) works... yes
checking whether the C compiler (cc ) is a cross-compiler... no
checking whether we are using GNU C... yes
checking whether cc accepts -g... yes
checking host system type... configure: error: can not guess host type; you must specify one

./configure ppc


cp /usr/libexec/config.* .



I don't know if the second one of those fixes the problem, but it has for me when I've tried compiling a couple other programs. Also make sure that you have the beta version, i think that is the only version of nmap that works with X.
