Note: This page does not reflect current infrastructure. It is for planning purposes.
This is an effort toward the end of Fall 2017 and early Spring 2018 to get new hardware, determining if we can use old hardware for anything, bring many vtluug services back to life plus add new services, fix major problems relating to the current infrastructure, make managing the current infrastructure easier, and to provide enough documentation so that anybody can have a very good understanding of how everything works without having to ask the officers about every little thing. This will be summarized in the Sysadmin Handbook
One major change is running an Proxmox cluster to managing everything, along with offering a VPS service in addition to shell accounts on Acidburn. This is not possible with the current hardware.

Getting new hardware
Cyberdelia is the only connected physical machine right now, besides our router. See Infrastructure 2017. We are planning to request funding from the SBB for new infrastructure as early as possible Spring 2018.
We are still working on exactly what to ask for, but here are some desirable things: //TODO link items
Priority | Item | Estimated Cost |
---|---|---|
10 | Dell Poweredge R620s | $600 ish |
Ideally we will get 2. A much more detailed price analysis will be done for the SBB.
\o/ We got $1300 to get 2 R620s!!
Hardware Configuration
Hardware
- temp88191
- Cyberdelia
- Wood
- 2x SGI (Phantomphreak/Joey)
- 2x R620s (Meltdown/Spectre)
Configuration
- Router/DNS Server: joey (sry temp88191 is too old)
- NAS: Cyberdelia due to its HDD capacity
- Proxmox hosted-engine: Both R620s, Phantomphreak
- HPC: Wood due to its 4U height that can easily fit gpus
Diagrams in progress
Networking
See Infrastructure for a mostly up to date networking layout.
This section reflects the services decscribed in the following section.
Public IPv4 addresses
Function | DNS | IP |
---|---|---|
Router/DNS | joey.vtluug.org | 128.173.88.191 |
Proxmox Controller | meltdown.vtluug.org | 128.173.89.244 |
Webserver | sczi.vtluug.org | 128.173.88.78 |
Shell Server | acidburn.vtluug.org | 128.173.89.245 |
FreeIPA | zerocool.vtluug.org | 128.173.89.247 |
Mirror | mirror.vtluug.org | 128.173.89.246 |
Matt's server | mjh.ece.vt.edu | 128.173.88.104 |
As per echarlie, "check rdns. if there isn't an entry, and it's in ece's allocated block, we can use it."
Private IPv4 addresses
We also use private addresses for things like NAS. This isn't 100% figured out yet, but we will probably do something like use 10.0.0.0-100 as static IPs and run DHCP on 10.0.0.101+.
IPv6 addresses
See Infrastructure.
Service Importance
Note: This secion's PoV does not taking into account the current state of service. Instead, it assumes services are being installed to a new infrastructure.
All necessary services send notifications to officers for alerts.
Syntax:
- Host (hostname)
- Services running on host
Urgent
Bare Metal
- Routing (joey)
- DNS (joey)
- Firewall (joey)
- NAS (ryzenfall,cyberdelia,fallout)
- Proxmox VE (meltdown,spectre,phantomphreak)
VMs
- FreeIPA (zerocool)

Issues with current services
When (re)implementing services listed above do the following changes.
VTLUUG Site
- We're literally proxying a static github page (vtluug.github.io)
- Probably should be redesigned to be slightly more dynamic using jekyll or flask or something
VTLUUG wiki
- Need meeting script
- Need to clean up a lot of old information
Gobblerpedia
- Lots of out of dat information
- Building templates
Wadsworth/phenny
- Things constantly break, but there's nothing we can really do about this
- Migrate to irc3 pythong library for a stable core
- Migrate SysV scripts to systemd unit files
VTBash
- Old shitty interface converted from python2 to python3
- Nothing good seems to already exist, so we probably need to write one from scratch
- Need to merge 2 old sqlite databases
- Causes bug when only 1 quote author is entered, this is why they can't be merged
Hokieprivacy
- Mobile formatting is fucked, at least for FF on Android
- Out of date
Linx
- Offload storage to NAS
- Binaries need updating
- Need to do reddit stress test
vtluug.org/files
- Need easy way fo non-root to add stuff here
- Train spamassassin
- Sieve doesn't seem to work
gopherspace
- who tf uses gopher
TOR services
linx, hokieprivacy, and the main site (hence vtluug.org) can be accessed over tor. advertise these urls or make them more memorable (or both)
