Build a simple, secure VPN connection now Last month, I began a new series on how to build a Linux-based Virtual Private Network (VPN) solution using OpenVPN. I described what VPNs are, what they're used for, and I listed some popular ways of building VPNs with Linux. That column ended with some pointers for obtaining and installing OpenVPN. This month, I continue with detailed instructions on how to build a quick-and-dirty single-user VPN connection that allows you to connect securely from...

While the Opera Web browser has yet to conquer our readers' PCs, the browser maker appears to have had more success on mobile devices. Case in point is Opera Mobile, now in version 10, the cross-platform UI framework for Android, BREW, Windows Mobile and Symbian S60 smartphones. Opera says that Mobile 10's raison d' tre is to open up the Opera browser experience to more people, on more devices, allowing operators and OEMs to implement the same user experience quickly and cost effectively across...

Cloud services are all the rage today, although some of my fellow Linux Journal staffers may scoff when they hear me say that. Cloud services is a nebulous term that can mean anything from completely hosted services (like Gmail) to virtualized, leased servers, such as those provided by Amazon's EC2 service. And, the latter is the subject of this article. Recently, with the advent of Ubuntu 9.10 (Karmic Koala), Canonical has added support for pre-baked Amazon EC2 images. This makes spinning up...

If you're the paranoid type and you're still stuck using Windows, you need to get Eraser. Eraser is an open-source security tool for Windows that makes sure deleted files are erased and overwritten completely before they are deleted. Many of us assume that when we delete a file, it's gone, but that's rarely the case. Most deletions merely mark the file as being deleted and recycle that area of the disk, nothing is written to it until the space is needed by a new file or by the growth of an...

Short Story

The short description is that you initiate a connection to Gateway. With that connection, you create a tunnel to port 22 on Server using the -L option to ssh You then can connect to a local port on Netbook that is the entry point for a tunnel that comes out at port 22 of the destination machine, which is Server. The tunneled connection is never decrypted on Gateway, so it stays secure. used in this article, it gets an argument that has three fields. The fields are separated by colons. The first...

I don't know if it's because I have a column in Linux Journal or because of the release of Karmic Koala, but either way, I seem to be installing Linux a lot lately. If there is one lesson I have learned from time spent on other hobbies, it's that things are always easier if you have the right tools handy. In this case, that means taking a step back from the install process to see what tools might help. ISO 9660 is the standard for storing images of CD-ROM filesystems. Although I vaguely...

Security Information Management SIM systems have made many security administrators' lives easier over the years.

Many SIM products are available today that perform well in this role, but none are as ambitious as AlienVault's Open Source Security Information Management OSSIM . With OSSIM, AlienVault has harnessed the capabilities of several popular security packages and created an...

Serial Console Access

Although it may seem antiquated, do not underestimate the value of serial console access to your Linux systems. When you find yourself in a situation where you can't access a system via SSH or other remote-access protocol, a good-old serial console potentially could be a lifesaver, particularly if you manage systems in a remote data center. Equally important is the ability to power-cycle a machine remotely. Absolutely nothing is more frustrating than having to drive to the data center at 3am to...
