10 minutes to an iptables-based Linux firewall (LinuxWorld). LinuxWorld tells how to harden your Linux 2.4 machines in no time at all. "Those heavy load issues aside, the 2.4 kernel provides a wealth of networking capabilities 2.2 lacks. These include stateful firewalling and solid quality-of-service options. One could argue that the 2.4 kernel, and its iptables firewall code, enables a person to build intricate firewalls capable of competing with the likes of CheckPoint."

How to create a Linux-based network of computers for peanuts (LinuxWorld). Here is a series of articles on LinuxWorld, on how to create an inexpensive Linux network. Part 1 covers how to get started. Part 2, rounding up more hardware. Part 3, configuring an application server.

Reading and writing Excel files with Perl (IBM developerWorks ). IBM's developerWorks looks at using Perl to parse Excel files. "The bad news is that Spreadsheet::WriteExcel can not be used to write to an existing Excel file. You have to import data from an existing Excel file yourself, using Spreadsheet::ParseExcel. The good news is that Spreadsheet::WriteExcel is compatible with Excel 5 up to Excel 2000."

Using Mandrake MD5 checksums (IBM developerWorks). A short shell application is used to show how to help secure Unix security. "Tracing modifications made to new system files with SGID/SUID flags is an extremely difficult task. But with enough experience and caution, system services and settings can be modified without changing standard file attributes (usually an administrator pays attention to the dates a file was created and modified)."

Tip Of The Week: Being strong and lazy (LinuxLookup). This week's LinuxLookup tip of the week takes a look at the use of brace expansion on the shell command line.
