Automating the Login Script

Post date: April 17, 2005, 10:04 Category: Miscellaneous Views: 2463 Comments
Tutorial quote: In a perfect world, you could spend a few weeks creating a system and the result would be a system that never required manual maintenance or modifications. Whether this ideal will ever be achieved is debatable, but it definitely won't happen in the near future. In the meantime, we still have to do things manually, even if only once in a while. When I must do things manually, I'm not usually happy about it. In fact, it usually means that there has been an emergency, so other people aren't happy about it either. In times like this, it is nice to have a consistent and efficient user interface on every machine. The information and examples presented in this article assume that you are using the bash shell. However, you can modify all of the scripts so that they work in other shells. In some cases, they might even work unmodified (like in the standard Bourne Shell [sh]). Other shells will also work, but they might have different methods for changing the prompt and creating command aliases. The principles in this article should be relatively easy to adapt to the shell of your choice.

Benchmarking Filesystems Part II

Post date: January 6, 2006, 22:01 Category: Benchmarks Views: 4676 Comments
Tutorial quote: After the last article was published, I have received more than a dozen requests for a second filesystem benchmark using the 2.6 kernel. Since that time, I have converted entirely to XFS for every Linux machine I use, so I may be a bit bias regarding the XFS filesystem. I tried to keep the hardware roughly the same. Instead of a Western Digital 250GB and Promise ATA/100 controller, I am now am using a Seagate 400GB and Maxtor ATA/133 Promise controller. The physical machine remains the same, there is an additional 664MB of swap and I am now running Debian Etch. In the previous article, I was running Slackware 9.1 with custom compiled filesystem utilities. I've added a small section in the beginning that shows the filesystem creation and mount time, I've also added a graph showing these new benchmarks. After the first round of benchmarks, I received a sleuth of e-mails asking for the raw numbers. The numbers are now included in tables at the end of this e-mail for both the last and current set of benchmarks.

Aggregating network interfaces

Post date: February 12, 2006, 07:02 Category: Network Views: 2976 Comments
Tutorial quote: Using more than one hard drive to achieve better performance and fault tolerance is very common. Less well known is that it's also possible to aggregate more than one network interface into a single logical interface. In Linux, this is handled by the bonding driver. Benefits of doing this are much the same as the benefits of aggregating discs using RAID: if one device dies, your server carries on working and by using two devices in parallel, performance can be improved.

What's up, Doc? A guide to Linux Documentation

Post date: January 6, 2007, 21:01 Category: System Views: 2789 Comments
Tutorial quote: If you're new to Linux, you've probably been told to read the manual, but what good is that advice if you don't know where the manuals are or how to use them? Here, in one place, is complate instructions on how to find and navigate the common Linux documentation systems, including man, info, READMEs, HOWTOs, HTML, PDF/PS, DocBook, Gnome and KDE help system, and command-line option conventions. The guide I wish I'd had when I was new to Linux!

SSH Port Forwarding Through a Proxy Server

Post date: April 18, 2005, 03:04 Category: Network Views: 2519 Comments
Tutorial quote: A common use of SSH is port forwarding (tunneling). This use causes traffic directed to a particular port to be sent to a specified port on another computer. Because traffic is sent through SSH, the traffic is encrypted, allowing the transmission of sensitive data through arbitrary services.
