Hackavision

Recently I bought a gaming computer with some of the best specs out there (i7, gtx670, 16gig ram, ssd, etc) and decided to finally set up my own Pentesting lab so I can practice breaking and securing "real" boxes of my own. My current setup consists of my router connected to my apartment's WAN using DHCP, which issues private DHCP leases to the connected boxes on my network. I have a Windows 7 laptop of my own, a Windows 7 desktop host machine running VMs, and a Ubuntu 12.10 server for all my main Linux needs (I have SSH set up so I can access this box from work and other places). My friends also connect to this network via Wifi, so there are random Win7 and OSx computers connected to it. As for my virtualized boxes, I have Windows XP (different SPs), Windows Server 2003, 2008, and 2012, Metasploitable 2, DVL (Damn Vulnerable Linux), BackTrack5R3 (I hack from this box), and a few other exploitable machines. I will be setting up a Windows Vista and a couple other *nix...

I'm afraid I've been very busy lately with a new job working overnights and figuring out all my college needs for moving in next month, but I've been doing a lot of research and reading on a few interesting topics so hopefully the next few posts will be very interesting. I've also updated a few of my posts including my wifi sniffing and securing your home network posts, so check those out! Today's post is about one of the most important netsec tools you will have in your arsenal. This program is called Nmap and is a free, open-source network auditing and security tool that we will use quite often while looking for vulnerabilities on networks. I will be explaining how to install and do some basic usage on Linux AND Windows (yay Windows!). I will be using my Backtrack 5 for Linux and Windows XP and hopefully get a Vista/Win7 part up as well.
