Linux Building an LDAP Server on Linux, Part 2
Post date: April 15, 2005, 12:04 Category: Network Views: 1120 Comments: 0
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.
Solaris Installing Solaris using JumpStart technology on an Intel laptop
Post date: April 13, 2005, 00:04 Category: Installing Views: 1489 Comments: 0
Tutorial quote: An interesting use of Solaris 8 on a PC laptop is for use with the JumpStart technology. It has never been so easy to install, re-install, or restore a server before.

As I am as a contractor, I am more on the road than in my own office, so I need a laptop, and preferably with Solaris installed, as I am focusing on Sun's products and applications.

Through the years, I have discovered that one of the most common scenarios is that a client needs a server installed, either because they just bought it, or need it re-installed, or recovered.

This article covers how to save time when installing servers, using the JumpStart technology on a laptop with Solaris for Intel.
Debian Run Your Own Webradio Station With Icecast2 And Ices2
Post date: February 18, 2007, 14:02 Category: Multimedia Views: 2088 Comments: 0
Tutorial quote: This tutorial describes how to set up an audio streaming server with Icecast2. In order that Icecast2 can stream audio to listeners we install Ices2. Ices2 is a program that sends audio data to an Icecast2 server to broadcast to clients. Ices2 can either read audio data from disk (Ogg Vorbis files), or sample live audio from a sound card and encode it on the fly. In this article we will let Ices2 read .ogg files from the local hard disk.
Debian Installing Joomla 1.5.6 On A Lighttpd Web Server (Debian Etch)
Post date: September 16, 2008, 05:09 Category: Installing Views: 1123 Comments: 0
Tutorial quote: This guide explains how you can install Joomla 1.5.6 on a lighttpd web server on Debian Etch. Joomla comes with an .htaccess file with mod_rewrite rules (for Apache) (to enable search-engine friendly URLs) that do not work on lighttpd. Fortunately Joomla has a built-in method to make search-engine friendly URLs work on lighttpd as well.
Debian Building A Virtual Server (VPS) With Debian 3.1 (Sarge) And OpenVZ
Post date: March 20, 2006, 14:03 Category: System Views: 1145 Comments: 0
Tutorial quote: In this HowTo I will describe the steps to be taken to prepare a server for OpenVZ virtual machines on Debian 3.1 (Sarge) 32Bit Linux. With OpenVZ you can create multiple Virtual Private Servers (VPS) on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers. The OpenVZ kernal patch is licensed under the GPL license, and the user-level tools are under the QPL license.
Debian Install and Configure Auth Shadow on Debian/Ubuntu
Post date: February 23, 2007, 12:02 Category: Miscellaneous Views: 1265 Comments: 0
Tutorial quote: Auth Shadow or mod-auth-shadow is a module for apache (and apache2, sort of) that enables authentication against /etc/shadow. The benefits being that any system user with a password can be authenticated for web_dav, subversion or simply an https server. The only other way to do this is with PAM. That method is dangerous because the apache user (www-data in my case) must be able to read /etc/shadow. Obviously, not a good idea. Auth Shadow accomplishes this safely by using a intermediate program called validate. This works because validate can be owned by root but executable by everyone. In the event that your server is compromised through apache, your password file will not be readable.
Debian Creating An NFS-Like Standalone Storage Server With GlusterFS On Debian Lenny
Post date: June 4, 2009, 06:06 Category: Installing Views: 1004 Comments: 0
Tutorial quote: This tutorial shows how to set up a standalone storage server on Debian Lenny. Instead of NFS, I will use GlusterFS here. The client system will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86-64 servers with SATA-II RAID and Infiniband HBA.
Ubuntu Nginx HTTP Server + PHP5 (With fast-cgi And xcache) On Ubuntu Feisty Fawn
Post date: October 10, 2007, 05:10 Category: Installing Views: 1838 Comments: 0
Tutorial quote: Nginx HTTP Server + PHP5 (With fast-cgi And xcache) On Ubuntu Feisty Fawn

This HowTo describes the implementation of Nginx with php5 support (through FastCGI). The fast-cgi process will be initiated via spawn-fcgi. Nginx is a great replacement of Apache with very low memory footprint and contrary to Lighttpd, does not suffer from memory leak over time. You can then use all the memory left to unleash the power of mysql for instance by increasing the default query cache.
Debian Running A File-, Print-, Proxy-, DHCP-, AND Time-Server For Small/Medium Enterprises
Post date: October 18, 2006, 13:10 Category: System Views: 1467 Comments: 0
Tutorial quote: This article shows how to run a file-, print-, HTTP proxy- DHCP-, and time server for small and medium enterprises (SME) on one single Debian Sarge system. It is very easy to set up, and management is done with an easy-to-use web interface called eBox so once the system is set up, you can forget about the command line. eBox was developed to administrate advanced services for corporate networks, and it was created for Debian Sarge.
Debian Cleaning up a Debian GNU/Linux system
Post date: November 25, 2006, 02:11 Category: System Views: 1294 Comments: 0
Tutorial quote: You arrive at a Debian GNU/Linux server which has some history of neglection. Let's suppose someone else neglected it but if your new-year resolution is to stop neglecting your beloved server, this applies as well.

One form of neglection is to install, install, install and never un-install any package. The common utility to perform installation and un-installation of packages is apt-get which adds to the problem because it doesn't have automatic removal of non-needed dependences.

That means that when phpMyAdmin was installed it also installed Apache, PHP and ton of other packages. phpMyAdmin was removed when it was no longer needed but Apache, PHP and the ton of packages remain there.

Aptitude to the rescue.
