== On the Network Architecture ==
''Further Information: [[Infrastructure:Networking]] and [[Infrastructure:Network]]''
Because VTLUUG infra no longer has IPv6 access[[File:Infra2019-network.png|thumb|500px|A simple network diagram by [[user:pew|pew]]. '''Update June 2021: Joey is dead, we are limited by long live Joey. Shellshock is the IP addresses assigned to usnew router. Cyberdelia is off.]]  We currently have some services with public IPv4 address, and what we can get through DHCP from ECE. As a consequence, all services which do not need to hosts have a global IP should move to the an internal network IPv4 address on the 10.9998.x.x/16 subnetand an IPv6 address assigned via SLAAC. In the future, it may [[Infrastructure:IPsec|VPN]]/[[Iodine]] should be wise to bridge this network to an ethernet port on cyberdeliaused. In theory, so that a switch services can be used to network our provided via a hidden service such as [[w:Tor|Tor]], but that introduces other servicescomplications. When we have rackspace to do soAlternately, services can require use of the [[Infrastructure:IPsec|VPN/]] on [[Infrastructure:Acidburn|acidburn]],[[Iodine]] access , or [[Secure Shell|ssh tunnelling]], although all of these limit usage to members with a shell account.All of these have the internal network will be necessarybenefit of NAT transversal, however.

== Website details ==
 
=== Current Setup ===
 All vtluug websites are run on nginx on milton[[Infrastructure:Sczi|sczi]]. These sites are currently functional:
* gobblerpedia.org
* hokieprivacy.org
* linx.vtluug.org
* snapchat.vtluug.org
* vtluug.org
* wiki.vtluug.org (this redirects to vtluug.org/wiki/)* bash.vtluug.org* vtluug.org/users/~$user
All of these sites exclusively allow for the use of tls TLS connections. Hokie Privacy has a cert from letsencrypt,while all other All services are verified by StartCom.use automatically updated Currently, milton has '''no startup script''' for the website. If things go down, someone has to run<pre>root@milton:/srv/http/vtluug.org# sudo -u www-data uwsgi --yaml uwsgi.yml</pre>in a tmux session, to restart [https://uwsgi-docs.readthedocs.org/en/latest/ uWSGI]letsencrypt certs.
==== Main Page ====
 It currently appears that the The main vtluug VTLUUG page (mostly written in php), is or was managed scraped from the [[w:Internet Archive|Internet Archive]] and added created as a github page at[https://vtluug.org/atrium Drupalgithub.io vtluug.github.io] as abackend, but for that to function, mysql needs to be running. uWSGI, django, and PHP make up most of the important features of the website in unknown ways. This was configured by is reverse-proxied through [[userInfrastructure:mutantmonkeySczi|Jamessczi]] at some point, we presume, but he is not available to provide more information on the setup.
==== Wiki ====
The wiki currently runs fully on MediaWiki hosted on nginx using a [https://github.com/vtluug/mediawiki-docker modified version of the official mediawiki docker image]. You can auth with the admin account, [[User:wiki-admin|wiki-admin]] or a Google account. See note on [[Main_page]] about why LDAP isn't working yet.
The wiki currently runs fully ===== Gobblerpedia =====Runs on MediaWiki hosted on nginx (the same Mediawiki instance as opposed this wiki. Similarly to the default include of apache2LUUGWiki, demanded by the Debian package).Postgres is used for only Google accounts or the database management, AFAIK, and authentication is through LDAPadmin user are supported logins.

=== Historically ===
Beyond these, we have data and nginx configurations for these (deprecated) sites, whichwere previously hosted on milton: ==== Needs Restoration ====These are VTLUUG services that haven't yet been properly restored:* foodfor.vtluug.org - For See [[WadsworthDead_projects]]'s .pickfood and .foodvote commands* tahoe.vtluug.org - mhazinsk's Tahoe-LAFS grid* git.vtluug.org - git hosting; previously gitosis* map.vtluug.org - OSM* vtbash.org - VT QDB* users.vtluug.org - member hosting of acidburn home directories ==== Deprecated ====These are no longer needed but we should preserve the data/config:* ccdc.vtluug.org - website used for the [[Collegiate Cyber Defense Competition]] in the spring of 2011.* jessicaandchristopher.net - member website* nagios.vtluug.org - was used for monitoring for a period but not kept up-to-date; the primary issue was that infrastructure, being hosted on the same server, tended to fail all at once* vtcybersecurity.org - member website* cdn.vtluug.org - member website* randynance.info - member website* uniluug.org - deprecated project* security.ece.vt.edu - REDACTED* wargame.vtluug.org - vtluug's wargame pre-vtcsec* munin.vtluug.org - failed attempt at monitoring* webchat.vtluug.org Prior to the current site, which was written in Python using Django starting in 2010 and deployed in 2011, the VTLUUG website was a WordPress instance. The files for this still exist. Additional files and configuration data exist for multiple versions of dokuwiki and mediawiki. There are also files for a NewsBlur installation which was never functional, and "bitcoin," the purpose of which is unknown. For a time, a static version of vtbash.org was hosted at bash.vtluug.org. Until recently, VTLUUG ran a Gopher server on Milton, with a small welcome page and access to /files. Git hosting was also provided; authenticated access was over SSH with [https://github.com/tv42/gitosis gitosis] and public access was via Gitweb and the insecure Git protocol. vtluug.org/public/$user/ was previously a source directory of files placed in a user's $HOME/public directory on NFS. <nowiki>[When? I thought it was always users.vtluug.org?]</nowiki>historic information
VTLUUG members also ran '''mirror.ece.vt.edu''', although it was never an official VTLUUG project. The IPv4 allocation for this domain is still available. === Considerations for the future Goals === It would be preferable to keep all existing sites functional. See [[userVTLUUG:andreim|Aam]Strategic_plan#Web_Services] suggested the use of [https://caddyserver.com/ caddy]to replace nginx, especially on static sites, because it provides automatic letsencrypt. It is also important to ensure there are '''startup scripts''' for sczi, so that a reboot of it doesn't result in a 10-hour website outage. ==== Encryption ====All sites should move to automatic letsencrypt certificates within the next few months. letsencrypt is still in beta, but it provides fully functionaland low-hassle 3-month certificates. They will have integration for nginx soon, which will decrease the complexity of getting certs. It may also be of interest to the club to revive [[monkeysphere]] signing on the servers. ==== Project Hosting ==== Most vtluug internal projects (e.g. HokiePrivacy) are currently hosted on git repositories on milton. How to move forwards with these is stillindeterminate. For public hosting, there has been some conversation about using [https://github.com/gogits/gogs Go Git Service (gogs)], for public,www-viewable git repositories. ==== Gobblerpedia ==== [[gp:Main page|Gobblerpedia]] is effectively non-functional currently, because account creation was disabled, to prevent spam. This needs to be addressed by adding captchas which are blacksburg-specific, limiting account creation access to local IP addresses, or enabling some form of LUUG-managed account creation. One suggestion was using CAS/Login future goals involving web services to authenticate, however that makes it difficult for Blacksburgresidents to add content, and has other disadvantages. ==== VTLUUG Main Page ==== This needs to be kept up-to-date, and have some way of adding calendar information. ==== VTLUUG Wiki ==== Meeting creation script needs to be re-implemented.

== Network Diagram ==We currently hold the IPv6 prefix <code>2001:470:8:6d9::/64</code> from HE's allocation due to our tunnel.When CNS finally sets up prefix-delegation, we might be able to get something from <code>2607:b400::/32</code>,which is VT's largest allocation.
This is the projected diagram of our network, once sczi is fully deployed and milton is phased out. At this time, razor may also lose its global v4 address.[[File{{:Infra2016-network.png]]Infrastructure:Network}}
