I enjoy recording screencasts in my spare time, and was hoping to get going recording some Ubuntu stuff.

I have a machine running Ubuntu Server.

Is there any easy way to record the screen?

Take a look at recordMyDesktop, also, here's a comparison of screencasting software.

If you don't have any GUI you might want to use this script (it's part of the util-linux-ng package):

user@srv % script logfile
Script started, file is logfile
user@srv % echo test
test
user@srv % exit
Script done, file is logfile

You'll find a recording of this session in logfile.

To track a SSH session in the same fashion you can use tee:

user@srv % ssh host | tee -a sshlog

However, both ways just dump commands and outputs, without any time assignments. So it's not applicable to record videos.

I recommend to use something like VirtualBox or VMware and record the windows with virtual machines inside...

ttyrec

ttyrec allows you to record your terminal sessions easily. However, they are recorded in a special format (not video), but the resulting files are smaller, and as such easily transferable.

I use playterm.org as a hosting for my ttyrec files. It allows you to view your terminal recordings over a browser (as if it were a video).

Steps

Recording

sudo apt-get install ttyrec
ttyrec
#Type your commands
git init #Example command
exit

A ttyrec session is similar to a screen session, except that it is recorded. After your recording is complete, a file with .tty extension will be present in your directory. You can upload that file to playterm, or pass people a download link.

Playing

To play the file, they'd need to use the ttyplay command. Just use ttyplay file.tty and it should play your terminal.

Editing

Since you are comfortable with adding audio later, I'd recommend copying the ttyrec file to a normal ubuntu desktop, and playing the recording (using ttyplay) while recording it using a screencasting session. You can record your voiceovers at the same time.
