Building a Linux virtual server

Post date: June 9, 2005, 14:06 Category: Software Views: 3537 Comments
Tutorial quote: With the explosive growth of the Internet, the workload on servers providing Web, email, and media services has increased greatly. More and more sites are being challenged to keep up with the growing demands and are employing several techniques to avoid overloading their servers. Building a scalable server on a cluster of computers is one of the solutions that is being effectively put to use. With such a cluster, the increasing requests can be easily managed by simply adding one or more new servers to the existing cluster as required. In this article we will look at setting up one such scalable, network load-balancing server cluster using a virtual server via the Linux Virtual Server Project.

Tunneling the hard way: using slirp, pppd and socat

Post date: January 29, 2006, 13:01 Category: Network Views: 12817 Comments
Tutorial quote: Every now and then you might come across a "bad" ISP. The one I have at home for example is dropping UDP packets ever so often when I try to play online games -- and it tends to drop random packets while I try to log onto a gameserver too which makes a certain game I like to play crash during the loading phase so it can't recover. I also heard of other ISPs blocking certain ports on external servers -- universities for example seem to like blocking p2p network ports and the school i was attending till last august blocked everything but port 80 for http -- including ftp which made even on-topic "research" a pita at times.
Usually there's three ways of working around this problem if "giving up" is not an option to you: a) change your ISP, b) use ssh to redirect ports, c) connect to an external VPN to route for you. a) can be tricky -- it's impossible if you're sharing the link with your parents and they insist on their email addresses or in the university/workplace/school scenario. b) will only work with single port/host combinations and for c) you will need a full-fledged rootbox idling around on the internet -- which tend to be expensive and "virtual servers" might not work because those often don't include tun/tap devices and/or kernel-level ppp support if you rent them and in case you rented them you probably can't fiddle around with its kernel to enable it (that was my problem at least). If any of this rings a bell to you, read on and discover method d)

Post date: January 6, 2007, 21:01 Category: System Views: 3429 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!

Optimizing Desktop Performance, Part II

Post date: May 24, 2005, 18:05 Category: Optimizing Views: 4035 Comments
Tutorial quote: As we discussed in last week's article, for most of its existence, people have distributed Linux as a workstation or a server rather than as a desktop. The default workstation that evolved has existed mostly for use by developers. So, when you install a Linux distribution with a graphical interface, it generally looks like what a developer might want. In addition, it performs similar to how many UNIX workstations work, which can seem slow.

In this article, we continue to look at the Linux desktop in a different light. Here, we think of it as a computer system with a fast interface that we can optimize for the knowledge worker and consumer.

DOS Emulation Under Linux

Post date: May 1, 2005, 17:05 Category: Emulation Views: 3739 Comments
Tutorial quote: Whether you need to run some legacy corporate application, or just want to play some of those old classic DOS games, it's easy to get going.

I've done this on a Slackware 9.1 Linux system with a 2.4.22 kernel, running KDE 3.1.4. The process should be very similar for most reasonably recent Linux distros.
