Network Diagnostic Tool (NDT) On Ubuntu 7.10 Server

Post date: February 24, 2008, 12:02 Category: Network Views: 4308 Comments
Tutorial quote: This guide will walk you through the setup process for implementing NDT running under Ubuntu 7.10 Server. For those unfamiliar with NDT, it is a network performance testing application. NDT will measure the throughput between your server and the desktops that you run the java client from.

Upstream Provider Woes? Point the Ping of Blame

Post date: April 14, 2005, 12:04 Category: Network Views: 3035 Comments
Tutorial quote: Your users are complaining that "the Internet is, like, all slow." Users are always complaining, but you're seeing a lot of timeouts when you check mail, surf the Web, or try to log in for remote administration. Or even worse, latency is so bad that you keep getting killed all to heck in your favorite gory violent online multi-player game, so you know there is a problem. But there a lot of potential bottlenecks between your PC and the outside world, like your Internet gateway, proxy server, firewall, Internet service provider, and so forth, so where do you begin?

One of the best and most versatile network tools you can have is a notebook PC running Linux. This lets you plug in anywhere to run tests and find out what is going on. Make it a nothing-to-lose box--don't keep data on it so you can wipe and reinstall the operating system as necessary, because you want to be able to run tests outside of firewalls. Don't run any services. You can put a minimal iptables firewall on it, as there is no point in being totally exposed, but keep it simple. (Use MondoRescue to make a system snapshot for fast restores.)

Virtual Hosting With PureFTPd And MySQL On CentOS 5.0

Post date: July 24, 2007, 22:07 Category: Installing Views: 4814 Comments
Tutorial quote: This document describes how to install a PureFTPd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database.

FreeBSD Networking Basics

Post date: April 13, 2005, 00:04 Category: Network Views: 4337 Comments
Tutorial quote: Beginners to Unix-like operating systems such as FreeBSD are often stymied by their network settings. Sure, the install process may have set up your NIC for you, but where do you go to view these settings, and how do you proceed if your NIC stops working? Since networking is such an integral part of computing, this article will demonstrate how to verify, configure, and optimize your network settings.

Aggregating network interfaces

Post date: February 12, 2006, 07:02 Category: Network Views: 3626 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.

Avoiding slow package updates with package diffs

Post date: September 18, 2006, 13:09 Category: Network Views: 3747 Comments
Tutorial quote: If you're using the unstable or testing distribution of Debian GNU/Linux you will almost certainly have noticed that apt-get uses daily-diffs for its package updates. In many common situtations this is more bandwidth efficient, however it isn't always appropriate.

apt-get is a standard command which is used by many Debian users to manage package installation, and upgrades. (Although there are also other package managers such as synaptic, or aptitude.)
