We have a server rack in the store room, and members may colocate one server.
Each member can use 1-2U of full-depth rack space, or some shared shelf-space for small ARM systems.
Hacklab's internet is provided by HUBS. Each member may use:
one public IPv4 address (from 18.104.22.168/27)
many private IPv4 addresses (from 10.38.41.0/24)
lots of public IPv6 addresses (from 2a04:5d00:70:1::/64)
Although our power usage is not metered we still have good reasons to limit consumption:
our landlord has to pay for it so we don't want to be a burden or to use enough to be noticed
power turns into heat, which has to be vented or air-conditioned out of the store room
it's ecologically unfriendly to use more than we need
When choosing a server, consider the amount of power that will be consumed and the amount of use that will be made of it. Many personal servers will be idle for a lot of the time, so a modern server with good power saving features would be desirable. Better still, get a low power Atom, Xeon-D or ARM system (e.g. Raspberry Pi).
BE AWARE THAT POWER-HUNGRY SERVERS MAY BECOME UNACCEPTABLE AT SOME POINT IN THE FUTURE. DON'T SPEND MONEY ON THEM.
Virtual machines are available on magnesium. Please ask Tim if you would like one.
Acceptable Use Policy
We don't have an official acceptable use policy at this time. Members should avoid illegal activities and consider whether their content will attract unwanted attention or damage Hacklab's reputation.
As a guide, anything that a normal hosting provider would allow should be okay. If your application or content would cause problems at another provider then you should discuss this with directors or the membership first.
Tor has been discussed previously and there were a number of objections on ethical and reputational grounds. Tor nodes are unlikely to be approved and should not be operated on our network.
For security auditing purposes, Hacklab may retain netflows (network traffic metadata) for up to 30 days.
Ask to be added to the colo
group, which will give you access to NetBox
Check the list of device types, and create one if your hardware isn't already listed.
Create a device entry for your server and record the location where it will be installed. For non-rack devices, the server will usually go on the shelving.
Allocate public IPs from the Server LAN
(one IPv4 per member, but as many IPv6 as needed) and link them to the device.
: is driven from NetBox data.
: forward entries are up to you, reverse entries should be requested from Tim.
Rack devices should be installed securely. If you don't have rails, get permission to stack on another person's server and don't stack multiple unsecured servers.
Route power cables at the right-side of the rack (view from the rear) and use cable ties to keep them neat and tidy. If you have dual PSUs, only connect one of them (dual PSUs will use more power, and there is limited benefit as we don't have independent power sources).
Route network cables to the left-side of the rack and connect to a Server LAN
port. Record the port used in NetBox or EHANA
(depending on the switch). If a new port needs to be configured, ask someone who is familiar with the switch to help.
If the shelving is used, then use the switch and power strips on the shelf. Tie your cables neatly.
Label your server with your name, and the server name (matching the one in NetBox).
