If you are running a virtual machine on your computer, you may want to access that virtual machine from another computer. Let’s use an example: Say you have an Ubuntu virtual machine with Apache running on port 80, and you want to show other people on your network to access the website you are hosting.
VMware Workstation includes a network utility that allows you to manage the virtual networks. Typically virtual machines will use NAT (Network Address Translation) to automatically assign a virtual IP address that hides behind your host address, but the default range of 192.168.200.0/24 may not work for everybody.
If you have installed multiple versions of an application into your system, you may wonder which command is being run from the command line when you launch it. This is especially useful to figure out the path of php when running on a shared server, as many shared servers have both php4 and php5 installed.
It’s easy to get the type of processor that a Solaris box is running on. While this might seem like a silly thing to need to know, if you are connected into a Solaris server at a remote location, you may need to know what type of processor is being used in order to install the correct packages.
The VMware Workstation 5.5.3 release notes indicate that it includes “Experimental support for Ubuntu Linux 6.10, 32-bit and 64-bit”, which means that you can install the VMware tools directly on Ubuntu 6.10 (Edgy Eft) without having to compile.
When you have automated backup jobs running on your database server, sometimes you forget that they are even running. Then you forget to check to see if they are running successfully, and don’t realize until your database crashes and you can’t restore it since you don’t have a current backup.
VMware Workstation provides a great ability to create shared folders so that your virtual machine can easily access data on your host pc. This saves a lot of time, especially when you are installing software that would otherwise take a long time to download.
Most people realize by now that using instant messaging from work can be easily tracked and logged. If you have access to an SSH server anywhere (mine is at my house) then you can setup a quick SOCKS proxy to forward all of your traffic through your home SSH server, and your employer won’t even know that you are chatting by monitoring the network.
You’ve just thought of a great new layout for your blog… but making changes to your blog while visitors are accessing it is generally a bad idea, especially if you are running an ad-supported blog. This How-To shows you the list of steps you need to take to get a copy of your production WordPress blog copied down to your local Ubuntu machine. (Should work for any debian linux)
Social bookmarking/news links are extremely popular these days. There are a ton of different websites out there, from the Digg.com’s to del.icio.us and furl. I personally only really use del.icio.us, but whatever your choice, you can be sure that you will have visitors that use at least one of the different services.
One of the gripes I’ve always had with the built-in WordPress functionality is that you can only specify the number of posts per page across the entire application, as opposed to being able to customize it per section or page. Thanks to a wonderful plugin by Matt Read, you can fix this easily.
