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/24 16 subnetand an IPv6 address assigned via SLAAC.

The wiki currently runs fully on MediaWiki hosted on nginx (as opposed to the default include of apache2, demanded by the Debian package).Postgres is used for the database management, AFAIK, and authentication is through LDAP. ===== Gobblerpedia ===== All but disabled currently, due to spam. Runs on MediaWiki ==== Linx ==== Uses [[User:andreim|aam]]'s [https://githubthe same Mediawiki instance as this wiki.com/andreimarcu/linx-server linx], and is an identical implementation Similarly to his site [https://linx.li linx.li]. === HIstorically === Beyond these, we have data and nginx configurations for these (deprecated) sitesLUUGWiki, whichwere previously hosted on milton:* ccdc.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.vtluug.org Further, we have server data for multiple versions of dokuwiki and mediawiki, a wordpress instance, "newsblur", and "bitcoin",and for a time had a static version of vtbash.org hosted at bash.vtluug.org. 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]. vtluug.org/public/$user/ was previously a source directory of files placed in a user's $HOME/public directory on NFS. VTLUUG was also previously responsible for mirror.ece.vt.edu, and still has the ip allocation for that DNS entry. === Considerations for only Google accounts or the future === It would be preferable to keep all existing sites functional. [[admin user:andreim|Aam]] 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 serverssupported logins.

==== Gobblerpedia =Goals === See [[gpVTLUUG:Main page|GobblerpediaStrategic_plan#Web_Services]] 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 for 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.
