Quick tip for those of you using AVG Firewall. I ran into an issue where, after installing AVG, my VMWare virtual machine would not longer connect to the internet. Windows still showed a connection and I could still ping (both by IP and domain names), but when I open a browser to load a web page, nothing happened.
At first I didn’t realize it was AVG that was causing the issue (it’s been a while since I last used my VM so I didnt make the connection right away). But some simple troubleshooting narrowed it down (set firewall to “Allow All“) and boom, internet started working right away.
Here’s a quick little tip to get your week started.
Remember back in the Windows 7 days (oh so long ago…) when all you had to do to change the network name was click on the icon in the “Network and Sharing Center” and it would let you change the network name as well as the icon?
What? You don’t remember? Okay okay, so granted this wasn’t a widely used feature by any means, but sometimes (especially if you’re in any sort of tech industry) its nice to name your networks.
Something as simple as describing how to change a PC to a static IP address (or back to a dynamic IP address ) is often overlooked by people who have been in the industry for a long time. I’m guilty myself of this. Too often while providing phone support (either internal or to customers) I will throw out “Oh yeah I just need you to set your computers IP address statically”. Most of the time I bet that I probably get a very evil glare on the other side of the phone.
You might be asking right now why you would ever need this information, and to be perfectly blunt most people will never need this information. However, if you ever have to phone support for any device that connects to the internet, believe me, the tech on the other line will praise you for knowing a little of the basics.
It happens to all I.T. guys sooner or later. You have a device on a network (maybe yours, or maybe a customers) and you need to figure out what IP address that device has. Some devices will provide this information via a console port, or maybe you can check your DHCP server’s reservation list… but what if you do not have access to any of these methods?
It recently came up where I wanted to force users visiting the IdleDev page to use a secure connection (https) domain wide (mostly for the development of Zero Day to ensure a secure connection is used at all times).
Unfortunately this was something that did not appear to be directly supported by my host. Luckily they do allow .htaccess and mod_rewrite, so from there it was easy.
By placing that text into your .htaccess file, and replacing “www.exampledomain.com” with your own domain, it will redirect the user to use an secure connection throughout the entire domain (essential for sending encrypted passwords, or any other data over the web that requires a secure connection).
