Tutorial quote: This chapter covers the iptables firewall administration program used to build a Netfilter firewall. For those of you who are familiar with or accustomed to the older ipfwadm and ipchains programs used with the IPFW technology, iptables will look very similar to those programs. However, it is much more feature-rich and flexible, and it is very different on subtle levels.

Firewalling with OpenBSD's PF packet filter

Post date: November 27, 2006, 02:11 Category: Network Views: 7471 Comments

PF offers firewalling, NAT, traffic control and bandwidth management in a single, flexible and sysadmin friendly system. Targeted at the seasoned or aspiring network administrator, this half day tutorial manuscript will give you some ideas about how to control your network traffic the way you want - keeping some things outside your network, directing traffic to specified hosts or services, and of course, giving spammers a hard time.

Installing and Configuring Exim4

Post date: February 25, 2006, 12:02 Category: Network Views: 3235 Comments
Tutorial quote: Installion of Exim4 from the latest Debian GNU/Linux packages is easy. The installation is now based around debconf. If you are upgrading from a simple Exim3 configuration, you can use exim_convert4r4 to convert your configuration file to the new format. If you used the previous version of this guide, which covered Exim3, the conversion should succeed without incident. I intend to discuss configuration via debconf, including setting up local delivery to Maildir format, handling local domain email, and configuring smarthosting for outbound email.

Installing Solaris 8 x86

Post date: April 13, 2005, 03:04 Category: Installing Views: 3343 Comments
Tutorial quote: Solaris x86 can picky when it comes to hardware. It may not work on hardware that's not listed in the HCL (Hardware Compatibility List). My older Pentium system's motherboard was OK, and it found the hard-drive I had connected to the primary IDE channel (on the motherboard) but it wouldn't recognize the CD-ROM drive even though it was connected to the secondary IDE channel on the motherboard. (I had better luck on a system where the CD-ROM drive was connected as the slave on the primary IDE channel. I prefer to keep the CD-ROM drive off the hard-drive channel but if all else fails you can try this to see if it works. :)
