== On the Network Architecture ==
''Further Information: [[Infrastructure:Networking]] and [[Infrastructure:Network]]''
[[File:Infra2019-network.png|thumb|500px|A simple network diagram by [[user:pew|pew]]. '''Update June 2021: Joey is dead, long live Joey. Shellshock is the new router. Cyberdelia is off.]]
We currently have some services with public IPv4 address, and all hosts have an internal IPv4 address on the 10.98.x.x/16 subnet and an IPv6 address assigned via SLAAC.
In the future, [[Infrastructure:IPsec|VPN]]/[[Iodine]] should be used.
Because VTLUUG infra no longer has IPv6 accessIn theory, we are limited by the IP addresses assigned to us, and what we services can get through DHCP from ECE. As be provided via a consequence, all services which do not need to have a global IP should move to the internal network on the 10.99.x.x/24 subnet. In the future, it may be wise to bridge this network to an ethernet port on cyberdeliahidden service such as [[w:Tor|Tor]], so but that a switch can be used to network our 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 All services use automatically updatedletsencrypt,while all other services are verified by StartComcerts.
Currently, milton has '''no startup script''' for ==== Main Page ====The main VTLUUG page was scraped from the website. If things go down, someone has to run[[w:Internet Archive|Internet Archive]] and added created as a github page at<pre>root@milton[https:/srv/http/vtluug.org# sudo -u www-data uwsgi --yaml uwsgigithub.io vtluug.github.yml</pre>in a tmux sessionio], to restart uwsgiand is reverse-proxied through [[Infrastructure:Sczi|sczi]].
=== HIstorically =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.
Beyond these, we have data and nginx configurations for these (deprecated) sites, which===== Gobblerpedia =====were previously hosted Runs on milton:* ccdcthe same Mediawiki instance as this wiki.vtluug.org* foodfor.vtluug.org* jessicaandchristopher.net* nagios.vtluug.org* tahoe.vtluug.org* vtcybersecurity.org* cdn.vtluug.org* git.vtluug.org* randynance.info* uniluug.org* map.vtluug.org* security.ece.vt.edu* users.vtluug.org* wargame.vtluug.org* munin.vtluug.org* vtbash.org* webchat.vtluugSimilarly to LUUGWiki, only Google accounts or the admin user are supported logins.org
Further, we have server data for multiple versions of dokuwiki === Needs Restoration ===These are VTLUUG services that haven't yet been properly restored:* [https://github.com/mutantmonkey/foodforus foodfor.vtluug.org] - For [[Wadsworth]]'s .pickfood and mediawiki, .foodvote commands. This is [[User:Timelord|jpo's]] fault.* tahoe.vtluug.org - [[user:mjh|mhazinsk's]] Tahoe-LAFS grid* git.vtluug.org - git hosting; previously a wordpress instance, "newsblur", and "bitcoin",redirect to gitweb with gitosis as the SSH backendand for a time had a static version of vtbash* gitweb.vtluug.org hosted at bash- git hosting; previously gitweb* [https://github.com/vtluug/campusmap map.vtluug.org.] - [[Openstreetmap|OSM]] based map of VT
VTLUUG previously supported gopher protocol over Milton, with a static version of the website available, and ran git and cvs servers,with git presumably being world-access through [https://github.com/tv42/gitosis gitosis].=== Historically ===
vtluug.org/public/$user/ was previously a source directory of files placed in a user's $HOME/public directory on NFS.See [[Dead_projects]] for historic information
VTLUUG was also previously responsible for mirror.ece.vt.edu, and still has the ip allocation for that DNS entry. === 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.

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}}
