Warning
Babbage has been recycled! The hard drives were erased using DBAN - an open-source hard drive wiping utility.
The contents were been backed-up (but not in perpetuity) to the file server known as Colin.
Purpose
Babbage was a general usage Linux server that lived in the space. It was largely been deprecated by services offered through the VM 'chomsky'.
Name
Named after Charles Babbage.
See also: System naming
DNS
- Internal: babbage.lan.london.hackspace.org.uk
- External: babbage.hack.rs
Logbook
Services
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.shpython /usr/local/bin/Lighted/lighted.pynot in use/var/www/fcagg/fcagg.sh
These services should be started automatically as daemons:
- /etc/init.d/apache2 start -- for cacti and normal web serving
- /etc/init.d/xinetd start -- this was for netcamfix which is not necessary now. (but having xinetd is not really anything to worry about)
- /etc/init.d/ssh
mosh -- is this actually started as a daemon? Not a daemon but port range rules fixed by tgreer for cab0lt. fixed for chomsky./etc/init.d/ircensus start -- October 2015 - asked teabot whether it was still useful and should be migrated to chomsky/etc/init.d/doorbot-listeners start-- babbage is no longer participating with doorbot./etc/init.d/irccat start-- old home of robonaut/etc/init.d/boarded start-- old daemon for talking with light up signs - retired/etc/init.d/lighttpd start-- for coolbot monitoring (why wasn't this just another apache instance? 2nd http server is overkill!)/etc/init.d/nginx -- for legacy 3-in-1 lathe ACNode management (why wasn't this just another apache instance? 3rd http server is even more overkill!)
These applications are also used in long-running sessions:
irssiNo one should be doing long-running sessions on babbage anymore. Move to chomsky. Seriously, this thing is gonna die, and you don't wanna die with it.
Networking
Config
Set the following in /etc/lighttpd/lighttpd.conf:
server.document-root = "/home/solexious/coolbot" server.port = 8022
Migration and Decommissioning
Kraptv Migrate http://hack.rs redirects, setup ProxyPass for cacti mgmt, and prepare environment for multi-user accessKraptv/Anybody Move glados files to Colin and change mountpoints for systems playing doorbot audio filesKraptv/Anybody Move userdirs/mystery-dirs (hopefully everything) to Colin - chmod/chown to updated LDAP credentials as necessary.cab0lt Migrate robonaut functions and historical info off to chomsky, merge updates to github archiverussss Migrate coolbot and laser statistics content/daemon to chomsky (or another system if code requires root access and lots of dedicated daemons)jasperw Migrate ACnode daemon for 3-in-1 lathe and others to acserverKraptv Migrate Cacti resources to chomsky - UPDATE: migrated cacti running alongside babbage 20 Oct 2015Thank you Sully for the remaining bits!Migrate irccensus to chomsky and update new cacti instance to point at new irccensus.UPDATE: migrated ircensus to chomsky --Yvanj (talk) 22:08, 4 November 2015 (UTC).Kraptv Final data copy using rsync before shutdown, wipe the drives using DBAN and hand over to its new owner - 21 November 2015- Speak fondly of the purpose it provided
