Earlier today while working with a friend at our offices we were playing around with a large NMAP scan of the anoNet network. His computer would not open the network topology in Zenmap because of a lack of RAM so we were looking at it on another laptop with much more RAM. After discussing it for a little bit we were curious how many hosts had been discovered on anoNet but initially I didn’t see an easy way to get this information. Use the information below for a quick count of hosts in Zenmap discovered via a NMAP scan.
I have been using a Windows 7 laptop for quite awhile as my daily driver and recently wanted to install Backtrack 4 in a virtual machine so I wasn’t required to dual boot or use a different laptop for BT4. I thought about using VMware as Martin wrote an article a couple months ago about installing Backtrack in a VM on Windows 7 but a couple months ago I discovered Windows Virtual PC during a Windows XP VM install. So far I have been really happy with Windows Virtual PC and decided to try installing Backtrack 4 in a Windows Virtual PC virtual machine. Below are the details on how to setup the Windows Virtual PC virtual machine and then information on how to install Backtrack 4 in that VM.
Here is the next in my series of posts as I tweak the new tools server to reach its full potential. I recently added a Intel i7 965 Extreme chip to the server and I am trying to get all the kinks ironed out. One thing I suspect is that the ram is not operating at its full potential. Both the ram and the chip list that they are capable of reaching a 1600 MHz speed so I want to get them running at that speed. Normally these things are fairly easy in Windows where we have a GUI and all kinds of fancy oveclockers tools but as you know from previous articles this server is a extreme definition of hybrid and it also runs a server version of Cent OS so we have no GUI. This has brought me to discover many new and interesting Linux CLI tools. Today I will show two different ways to check your ram speed and also get some other useful information.
I have configured a Linksys WRT600N to connect using PPTP to my company’s VPN server in the past as noted in this previous article. I have since swapped out the Linksys WRT600N with a Linksys WRT54GS because I wanted to replace the antennas with larger antennas to work on getting better wireless coverage in my workshop in the basement and with the primary wireless router being located on the second floor of my house I needed to do numerous things to squeeze as much signal as possible. I also noticed numerous other issues with the WRT600N including the router locking up on a regular basis as well as dropping connections.
You can stop Windows XP from using the pagefile.sys file for SWAP memory however it is not typically recommended. Most suggestions on the Internet say that you should always make the pagefile 1.5 times the amount of physical memory you have in the Windows PC. It is also mentioned that you should have at least 1GB of memory if you are going to disable the Windows SWAP. Windows should not use SWAP (pagefile.sys) unless it has run out of RAM (memory) to use however I noticed on my PC that it appeared as though SWAP was being used after only 20% or so of my actual physical memory was being used so I decided to try disabling the SWAP and so far it has made most things faster on my PC.
To disable the Windows SWAP memory usage follow the below simple steps which will require a reboot at the end of configuration.
