Welcome to OPS535 - Advanced Network Administration
What This Course is About
This course teaches the maintenance, administration, and troubleshooting in an Linux virtualized environment . Students will learn to install configure, customize, test and maintain common services available on Linux servers. This course is the third in a series of courses about Linux technologies.
- ULI101 taught you to be Linux user.
- OPS235 taught you to move from being a Linux user to being a Linux system administrator.
- OPS335 taught you to administer Linux servers (web servers, DNS servers, FTP servers, file sharing servers).
- OPS435 taught you how to automate server administration tasks using scripting tools
- OPS535 give you an opportunity to put your Linux Sever administrator skills in action by integrating NFS, NIS, DNS, LDAP, HTTP, SMTP netowrk services and provide solutions to real world problems.
In this course you use a removable disk pack with the lab computers to set up a Linux system as a IP network router. You will also set up several additional Linux systems using "Virtual Machines" to provide various network services.
Learning by Doing
Most of the learning in this course occurs through the hands-on problem solving that takes place in the ten labs and two assignments. Therefore, it's very important to stay up-to-date with the coursework, and to practice until you have confidently mastered each task.
All of the software used in this course is open source software, so you are free to use, modify, and redistribute it. This means that you can install it as many times as you want on as many different computers as you would like. It also means that you can tinker with it -- you can take it apart, see how it works, and put it back together in the same or a different way, limited only by your time and ambition. You are encouraged to experiment and question liberally.
Weekly topic, lab, and assignment information is available on the OPS535 Weekly Schedule page.

Tips and Suggestions
- Always shut down your system under software control, rather than using the reset or power buttons. You can shutdown using the GUI or with the
- If you get a message about the gnome-power-manager configuration at the login screen, you may have run out of disk space. Switch to a character-mode virtual terminal (for example, switch to VT2 by pressing Ctrl-Alt-F2). Login and take a look at the available space (with the command:
df -h). If the
/filesystem is full, delete some files (such as unused VM images in
/var/lib/libvirt/images) and then reboot the system.
