Building an LDAP Server on Linux, Part 2

Post date: April 15, 2005, 17:04 Category: Network Views: 4147 Comments
Tutorial quote: Welcome back! In Part 1 we learned basic concepts of LDAP and the uses for an LDAP server. Today we'll install and configure an OpenLDAP directory.

A quick note before we get started: this is LDAP 101. We are not installing any kind of encryption or strong authentication; we'll get to that in part 3. In my experience, learning LDAP in small chunks works best. (Then again, perhaps I'm just a bit dim.) So sit back, strap in, and keep your fingers away from the training wheels.

"The wise sysadmin will consult the documentation for their distro; it's quite possible that OpenLDAP will be packaged and ready to go in a pleasing manner (or ready to go in an odd manner--you never know). I'm all for easy--if your particular distribution provides an easy way, use it. RPMs can also be obtained from rpmfind.net, which thoughtfully lists all the required additional packages.

"Debian of course goes its own merry way. apt-get does the job just fine; the tricky bit is finding out the package names. Debian users want ldap-utils; slapd, which is OpenLDAP; and libdb4.1, to get the Sleepycat DB. These three components are enough to get you up and running. apt-get will walk you through a minimal configuration and will automatically start up slapd, the LDAP server daemon.

Filesystems (ext3, reiser, xfs, jfs) comparison on Debian Etch

Post date: April 23, 2006, 08:04 Category: Benchmarks Views: 6565 Comments
Tutorial quote: There are a lot of Linux filesystems comparisons available but most of them are anecdotal, based on artificial tasks or completed under older kernels. This benchmark essay is based on 11 real-world tasks appropriate for a file server with older generation hardware (Pentium II/III, EIDE hard-drive).

Flip - Convert text file line endings between Unix and DOS formats

Post date: March 2, 2009, 07:03 Category: System Views: 3372 Comments
Tutorial quote: This program converts line endings of text files between MS-DOS and **IX formats. It detects binary files in a nearly foolproof way and leaves them alone unless you override this. It will also leave files alone that are already in the right format and preserves file timestamps.User interrupts are handled gracefully and no garbage or corrupted files left behind. ‘flip’ does not convert files to a different character set, and it can not handle Apple Macintosh line endings (CR only). For that (and more), you can use the ‘recode’ program (package ‘recode’).

How to configure Linux as Internet Gateway for small office

Post date: February 17, 2009, 08:02 Category: Network Views: 6337 Comments
Tutorial quote: This tutorial shows how to set up network-address-translation (NAT) on a Linux system with iptables rules so that the system can act as a gateway and provide internet access to multiple hosts on a local network using a single public IP address. This is achieved by rewriting the source and/or destination addresses of IP packets as they pass through the NAT system.

DOS Emulation Under Linux

Post date: May 1, 2005, 17:05 Category: Emulation Views: 3737 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.

Essential house keeping in Ubuntu

Post date: December 8, 2005, 11:12 Category: System Views: 3567 Comments
Tutorial quote: I started using Ubuntu Breezy ver 5.10 a month back on my machine. Prior to that I was exclusively into Fedora. What drew me to Ubuntu was the huge number of packages in its repositories including softwares which I find useful on a day-to-day basis like Tomboy which I had to compile from source in Fedora. But the Ubuntu CD comes with the base packages which support only open file formats. So if you want support for proprietary file formats like mp3 and quicktime support as well as install softwares not included on the CD, then you have to do some work.

I call it essential housekeeping because it is not exactly a problem, but only a matter of finding out how to get the necessary support. Here I share my experiences in putting the Ubuntu house in order on my machine.
