Conclusion

Prerequisites:

All students should already be comfortable with basic Linux or UNIX administration and have a solid understanding of network concepts and the TCP/IP protocol suite.

Training Materials:

All attendees receive comprehensive courseware and a related textbook.

Software needed for each student PC:

Windows, Mac, or Linux PCs with at least 4 GB RAM
Accelebrate can provide a VirtualBox or VMware environment with all software needed for the class
- This class can be taught using the Linux distribution of your choice
- For classes delivered online, all participants need either dual monitors or a separate device logged into the online session so that they can do their work on one screen and watch the instructor on the other. A separate computer connected to a projector or large screen TV would be another way for students to see the instructor's screen simultaneously with working on their own.
