Need Internet!

Image
Not so many years ago when I was a tech, needed to use the internet to solve a vital problem. The internet was allegedly down. Contacted the administrator (who had umpteen MSce certifications) who in charge of that area confirmed that the net was inaccessible because they were having problems. So I asked what I could do and the reply was nothing could be done. Being independent as I am and not willing to give up so easily, I decided to tinker a bit.  Decided to go into the student CS lab and use one of the desktops as a test machine. Having set up a lot of the cabling and routers, was pretty knowledgeable of the systems, Fortunately also had systems admin rights also in those systems. Now for the tinkering,. Logged into a system and immediately went to the ip settings. Dns server was down so, I used a public dns server in its place of the local dns server.  Could not get a ip address from that server, so I used a static ip address that would not interfere with the netwo...

Unsecured cameras!

Your web cams and CCTV may not be  secure. Use a search engine with the ipaddress of the unit and one of these search terms one at a time to see if the unit is accessible. These are only a few of many. inurl:/view.shtml intitle:”Live View / – AXIS” | inurl:view/view.shtml^ inurl:ViewerFrame?Mode= inurl:ViewerFrame?Mode=Refresh inurl:axis-cgi/jpg inurl:view/index.shtml inurl:view/view.shtml liveapplet intitle:liveapplet allintitle:”Network Camera NetworkCamera” intitle:axis intitle:”video server” intitle:liveapplet inurl:LvAppl intitle:”EvoCam” inurl:”webcam.html” intitle:”Live NetSnap Cam-Server feed” intitle:”Live View / – AXIS 206M” intitle:”Live View / – AXIS 206W” intitle:”Live View / – AXIS 210″

Testing voip.

Voip or voice over IP is a method  for sending and receiving voice messages over a computer network. Come along way since the invention of the telephone by Alexander Graham Bell. Actually you can do a whole lot more than that. It can be very complicated to set up. Fortunately. there is what is known as a "live" cd that is pretty much pre-configured that only the few additional settings will get you up and running in a few minutes. it is known as CosmoPBX. You can get it and more information at: http://cosmopbx.sourceforge.net/ . You must be forewarned though that it is NOT SECURE , so do not use it in a production environment. In any case, a great tool for experimentation with use on an intranet or private network. With wifi access to your network, voip applications for your touchpads (android and etc) should connect to it fine. For our purposes, we booted it in a virtual machine.  You can use a web browser to connect to the server remotely to con...
