Denning

Runs the non-vital services that used to run on Boole. Might get used for other stuff as well. Same hardware as Boole

Runs zone minder and has a not very good 4 port TV capture card in it, currently connected to the 3 yard cameras and the rear lobby camera.

Also a netboot server, provides:

  • Diskless i386 and amd64 debian wheezy
  • Rescue and Install for debian wheezy.
  • partition magic
  • memtest
  • dban
  • Voyage (a minimised debian disto that can run from readonly media) Warning : the Voyage auto install kernel will reformat things they are booted on without prompting.

Also runs ansible for setting up machines in the space.


Issues

Has only a single mechanical harddrive so vulnerable to data loss.

using Ansible with a Rasbperry Pi

dd raspbian image (use the 02-09 one to avoid usb issues)
boot pi
watch dhcp logs on boole
ssh pi@ip
passwd: raspberry

sudo raspi-config
update it
expand filesystem
change password
boot to console
advanced options -> hostname

cd /etc/network
edit interfaces to get a static ip
reboot

on boole:

add hostname to fwd and rev. dns, don't forget to commit your changes.

log into denning with ssh keys forwarded

add hostname to /etc/ansible/hosts in both the [lhshosts] and [rpis]
sections, and [doorbot] if it's a doorbot, make the syslocation="something sensible"

then:

if it's a replacement for an old machine then:

ssh-keygen -R hostname
ssh-keygen -R hostname.lan.london.hackspace.org.uk
ssh-keygen -R ipv4 address (?)
ssh-keygen -R ipv6 address (?)

then:

cd /etc/ansible

install python-apt which ansible needs:

ansible -vvv -u pi -k -s -m command -a "apt-get -y install python-apt" "hostname"

Then run it

ansible-playbook -u pi -s -k -l "hostname" lhs/site.yml

The 2nd one will add our users, ssh keys, packages, etc etc.

notes:

not sure how resolv.conf gets setup, I thought having:

iface eth0 inet static
        [...]
        dns-nameservers 172.31.24.2
        dns-search lan.london.hackspace.org.uk

Would sort it, but maybe that dosn't and we got lucky from dhcp?

The dns stuff in /etc/network/interfaces appears to be bogus and resolv.conf needs to be
done manually, add to ansible.
