HOWTO run an UCC:LAN

First, set a date. You will need at least two days to get things sorted out, but for optimum promotion you should have a date well in advance.

Well before the date

  • Get a night pass by e-mailing, phoning, or lassoing the Guild president ([mailto:[email protected]]). Make sure you know where it is!

  • Make sure the Coke and Snack machine are stocked.

Before people arrive

  • Phone security on 3020 to let them know you have a night pass and will be in the building overnight.
  • Make sure you've got the night pass pinned to the door.
  • Clean up in the loft - sweep, empty bins, tip water over resident roleplayers.
  • Arrange the tables and chairs (it gets really hot under the lights, so don't put people sitting there)
  • Sort out power: use extension cords to pull from as many different circuits as possible (i.e. the wall in the loft, the corridor wall under the fire extinguisher outside UWAnime, drop a cord down into UCC) and make sure there aren't too many power boards connected to each other.
  • Bring the CAT5 box upstairs.
  • Get the switches out of the machine room and connect them up - use a gigabit switch as uplink.
  • Find a Wheel member and get them to set up the network:
    • The loft is VLAN 5.
    • Put any clubroom Windows machines on VLAN 5 - on the Ciscos, don't do 'wri mem' and then you can just reboot them when you're done.
    • Don't put any of the Mac or Linux machines on VLAN 5. NFS will break.

    • Check the firewall - it should look something like this, with line 2 commented and line 4 uncommented. If it's the other way round, change it.

{{{# And Loft #$IPTABLES -A FORWARD -i eth0.5 -d 130.95.13.0/24 -j UNTRUSTED # Use this instead for LANs $IPTABLES -A FORWARD -i eth0.5 -d 130.95.13.0/24 -j ACCEPT }}}

  • Start the TF2 and ET servers.

During the night

  • Consider a pizza order
  • Make sure the bottom doors stay locked (especially if there's a Leisure, etc. event on)

  • If people have odd DHCP problems:
    • Make sure we're not running out of leases.
    • Make sure there are no extra DHCP servers on the network. You can run the following command as root Madako to scan for rogue DHCP servers.

/root/dhcp_probe-1.0.4/src/dhcp_probe -fc /root/dhcp_probe-1.0.4/extras/dhcp_probe.cf eth0.5

The next morning

  • Even though you're tired and/or wired, the more packing up you can do the better.
  • Put the network back to normal - including changing the firewall back.
  • If you're going to go to sleep and there's no-one else around, lock the top doors. Stuff has been stolen before.
