I am working on learning network security… so I went and picked up the NMAP Network Scanning book (ISBN: 978-0-9799587-1-7) from Gordon Lyon and Insecure.org.
During my reading he talks alot about an Intrusion Detection System (IDS). Apparently IDS’s are used to detect attacks on their networks including something benign as a port scan. This got me thinking… doesn’t my MS Action Pack include something like that… indeed it does… two in fact. The ISA 2006 and it’s newer replacement Threat Management Gateway (TMG 2010).
Any respectable hacker would jump at the chance to set it up and “hack” yourself to see what happens right? OF COURSE!!!
I’ve setup the new system and placed it on the “edge” of my network. This puts it in exactly the right spot to have the largest exposure… right…
So, I’m researching the NMAP tool from Insecure.org… and needed to compile it on my various linux test boxes.
suse1:~/nmap # ./configure
checking whether NLS is requested… yes
checking build system type… i686-pc-linux-gnu
checking host system type… i686-pc-linux-gnu
checking for gcc… no
checking for cc… no
checking for cl.exe… no
configure: error: in `/root/nmap’:
configure: error: no acceptable C compiler found in $PATH
See `config.log’ for more details.
Only problem is they are fresh installations with the minimum of options during the setup of the computers. IE: I went with basic server options with no additional packages during the install of each flavor of Linux.
So where do I go from here… welp, download and compile of course.
In the end I needed 15 different rpm packages from my SuSE DVD… and they needed to be installed in the following order:
I’ve posted them at my files webiste http://files.moranit.com/SuSE11/
After installing all of these, the remaining installation proceedure outlined on the nmap website went perfectly… I now have a working version on my SuSE 11.0 text box.
