Building an LDAP Server on Linux, Part 2

Post date: April 15, 2005, 17:04 Category: Network Views: 3661 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.

How To Harden PHP5 With Suhosin On Fedora 7

Post date: July 25, 2007, 23:07 Category: Security Views: 3323 Comments
Tutorial quote: This tutorial shows how to harden PHP5 with Suhosin on a Fedora 7 server. From the Suhosin project page: "Suhosin is an advanced protection system for PHP installations that was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core. Suhosin comes in two independent parts, that can be used separately or in combination. The first part is a small patch against the PHP core, that implements a few low-level protections against bufferoverflows or format string vulnerabilities and the second part is a powerful PHP extension that implements all the other protections."

Restricting Users To SFTP Plus Setting Up Chrooted SSH/SFTP (Debian Squeeze)

Post date: September 6, 2011, 07:09 Category: Miscellaneous Views: 5340 Comments
Tutorial quote: This tutorial describes how to give users chrooted SSH and/or chrooted SFTP access on Debian Squeeze. With this setup, you can give your users shell access without having to fear that they can see your whole system. Your users will be jailed in a specific directory which they will not be able to break out of. I will also show how to restrict users to SFTP so that they cannot use SSH (this part is independent from the chroot part of this tutorial).
