If you are an Ubuntu user and simply cannot wait to get the latest nmap features, follow the procedure below. Throw this into a file and call it, ‘build_nmap’ and copy it to the /etc/cron.daily directory and you will have a daily build of the latest and greatest version of nmap.
P.S. The same procedure will also work for you Backtrack geeks.
|
1. Open a shell terminal. 2. svn co –username guest –password “” svn://svn.insecure.org/nmap/. 3. cd nmap 4. ./configure 5. make 6. sudo make install |
This just in….US-CERT found to have plethora of security holes in their network. End of the world predicted in a matter of days.
For those of you actually know what encryption is and how to use it, here’s my public key to send secure transmissions.
