Warning

the latest kernel (and possibly others) can't mount the root fs, i don't know why. using the oldest kernel works, but is less than ideal. next time it's rebooted please check if any of the newer kernels work.

Purpose

Babbage is a general usage server that lives in the space.

Access

Hackspace members do not automatically receive a Babbage account. To access Babbage, ask for an account on the IRC, and then connect via SSH.

Security

Since many hackspace members have root access, and since very little effort (ok, no effort whatsoever) is put into securing Babbage you should assume that the likelyhood of someone breaking into it is quite high. Don't leave any files on there that you don't have a backup of, and don't assume any data on Babbage will remain confidential. Be careful about ssh forwarding and beware of thing like github passwords or passwords to other machines in the hackspace.

These must be running in sudo screen sessions belonging to root (run from their directories):

Please use screen -S motion, screen -S irccat, etc.

• /usr/local/bin/scripts/startmotion
• /home/jonty/irccat/irccat.sh

• /etc/init.d/doorbot-listeners start
• /etc/init.d/xinetd start
• /etc/init.d/apache2 start
• /etc/init.d/lighttpd start
• /etc/init.d/boarded start

• ssh
• mosh
• httpd
• nginx (for ACNode, etc)

These applications are also used in long-running sessions:

Webcams

Webcams are controlled by the motion deamon. This can be run from `/usr/local/bin/scripts/startmotion` (preferably in a screen session)
