Linux WAN Routers
The intent of this article is not to say that Linux routers will make traditional routing hardware obsolete. When considering routing hardware, make sure that the tool fits the job at hand. If you have a T-3 to the Internet or want to tie together remote sites with ATM, you probably need to be shopping for equipment designed explicitly to switch and route packets at those speeds. By the same token, why go to the extra expense and trouble to deploy a special-purpose piece of hardware, along with all of the inconveniences that come with it, when you only need to route 128Kbps or even 1.5Mbps?
Because no one can foresee all of the demands that will be placed on their routing environment, flexibility and expandability are desirable in any solution. The Linux kernel is rapidly supporting increasingly more sophisticated types of traffic-shaping and packet monitoring. Routing hardware, including the processor, can be upgraded inexpensively. Furthermore, this same hardware can provide additional functions. Finally, a Linux router comes equipped with a complete set of familiar tools for monitoring and customization.
For a minimal investment in hardware and time, you can try a Linux router for a new link or to act as a backup for your current link(s). If you are new to data communications or need support, you are more likely to find a Linux hacker who can read (which is all it takes to get a Sangoma card running) than to find a BigName router guru. Typically, Linux folks are pretty friendly and willing to help. After all, some of this stuff is just neat. For business environments, the availability of Linux talent is increasing, and training for this environment is substantially less expensive than for closed-systems. Because Linux is open, your investment of time and capital is better protected. Give it a try. You will not regret it!

In modern computer systems, privacy and security are mandatory. However, connections from the outside over public networks automatically imply risks. One easily available solution to avoid eavesdroppers’ attempts is SSH. But, its wide adoption during the past 21 years has made it a target for attackers, so hardening your system properly is a must.
Additionally, in highly regulated markets, you must comply with specific operational requirements, proving that you conform to standards and even that you have included new mandatory authentication methods, such as two-factor authentication. In this ebook, I discuss SSH and how to configure and manage it to guarantee that your network is safe, your data is secure and that you comply with relevant regulations.Get the Guide
