Firewalling with OpenBSD's PF packet filter

Post date: April 19, 2005, 02:04 Category: Network Views: 6493 Comments
Tutorial quote: PF operates in a world which consists of packets, protocols, connections and ports.

Based on where a packet is coming from or where it's going, which protocol, connection of port it is designated for, PF is able to determine where to lead the packet, or decide if it is to be let through at all.

It's equally possible to direct network traffic based on packet contents, usually referred to as application level filtering, but this is not the kind of thing PF does. We will come back later to some cases where PF will hand off these kinds of tasks to other software, but first let us deal with some basics.

We've already mentioned the firewall concept. One important feature of PF and similar software, perhaps the most important feature, is that it is able to identify and block traffic which is you do not want to let into your local network or let out to the world outside. At some point the term 'firewall' was coined.

Speeding Up Perl Scripts With SpeedyCGI/PersistentPerl On Debian Etch

Post date: September 12, 2007, 22:09 Category: Optimizing Views: 3791 Comments
Tutorial quote: This tutorial shows how to install and use SpeedyCGI (also known as PersistentPerl) on a Debian Etch system. SpeedyCGI is a way to run Perl scripts persistently, which can make them run much more quickly. It keeps the Perl interpreter running, and during subsequent runs, this interpreter is used to handle new executions instead of starting a new Perl interpreter each time.

Using the GNU Privacy Guard

Post date: April 16, 2005, 00:04 Category: Software Views: 2408 Comments
Tutorial quote: Tonight we will investigate the gnupg utility (version 1.07). I will be running it on an OpenBSD 3.2 system but, as usual, any unix-like system should not display any significant differences. I will assume that GPG is already installed.

The GNU Privacy Guard can be regarded as a complete replacement for the popular PGP (Pretty Good Privacy) software. The difference between the two is that GnuPG does not have any licensing restrictions and it also runs on more platforms. They are both open source products. Although owned by a commercial entity, a freeware version of PGP is available (although only for Windows and Macintosh).

In a nutshell, what all this software does is allow two parties to communicate securely. This implies the following:
- the message has arrived at its destination unaltered
- the message can only be read by its intended recipient
- the authenticity of the sender has been verified by the recipient

How To Limit CPU Usage Of A Process With cpulimit (Debian/Ubuntu)

Post date: September 14, 2009, 09:09 Category: Miscellaneous Views: 3347 Comments
Tutorial quote: This tutorial shows how you can limit the CPU usage of a process with the tool cpulimit on Debian/Ubuntu. cpulimit is a simple program that attempts to limit the CPU usage of a process (expressed in percentage, not in cpu time). This is useful to control batch jobs, when you don't want them to eat too much CPU. It does not act on the nice value or other scheduling priority stuff, but on the real CPU usage. Also, it is able to adapt itself to the overall system load, dynamically and quickly.
