Network Scanner Saved My Life

Share

Let me start off this post by telling you how important it is to document everything in the world of IT, and then keep those documents somewhere where they are easy to find.  Today, I ran into a problem with not being able to find my notes.  So, I got to finally use this tool I downloaded awhile back.  It is called LanSpy 2.0.  You can find it here:  http://lantricks.com/lanspy/

LanSpy 2.0 is a network security and port scanner.  Let me give you a little back story before I tell you about the beauty of this tool. 

Today, I was at one of my client’s stores working on a wireless issue.  This is a small grocery store, so the network setup isn’t anything fancy.  They have a few switches, two VOIP boxes, a couple of routers, and an access point.  Unfortunately, I couldn’t find my notes for the IP addresses of the different devices.  The router is easy to get, but I needed to get into the access point box.  Usually if we have multiple network devices that require an IP, we make it either one up or one down from the IP we give the router.  That wasn’t the case with this one. 

What is awesome about LanSpy, is when it scans the IPs, it also gives the MAC address of each device.  Since I had access to the access point, I could get get the MAC address from the bottom of the device and go down the search results until I found the IP that was assigned to it.  Pretty painless. 

LanSpy also gathers a ton of other useful information such as users, logged in users, shared resources, open files, etc.  For a complete list, please visit their site at http://lantricks.com/lanspy/.

So if you get stuck in a pickle, like I did, or just want to make sure your own network is secure, give this tool a try.
