This page documents VTLUUG's infrastructure post-[[CVL eviction]]. It is intended as a scratch pad ofsorts for organizing infrastructure changes, since [[Infrastructure:Log]] is incredibly out of date, andthere are a lot of details which must be sorted out before major infrastructure changes can be made.

''Main Article === NFS Hosts ===* [[Infrastructure:CyberdeliaDirtycow|dirtycow]]- Primary NFS server, 8x2TB raidz2 array* [[VTLUUGInfrastructure:InventoryCyberdelia|cyberdelia]]''- OFF, 7x1TB raidz2 array, sitting on shelf instead of shelf

=== VM Hosts ===* [[Infrastructure:Meltdown|meltdown]] - Primary VM/docker host* [[Infrastructure:CyberdeliaSpectre|Cyberdeliaspectre]] is the only connected physical machine right now. It contains 48 GB of memory- Secondary VM/docker host, for example user VMs === Router ===* [[Infrastructure:Shellshock|shellshock]] - 3 disk RAID1 array with 4 ethernet interfaces; only eth4 is connected and is attached to br0. All hosts are on the ECE network behindrouter.ece.vt.eduour own 1 Gb/s port with [[Infrastructure:Joey|joey]], a gateway featuring ARP proxying but no IPv6.

Contact itso-g@vt.edu for firewall exceptions.When deploying new hosts, make ssh listen on both 2222 and 22. [[Infrastructure:Acidburn |Acidburn]] currently listens on 443 3128 as well. === Other hosts ===* [[Infrastructure:Wood|Wood]] is sitting in our rack turned off because we don't have a use for it currently. It is in a 4U case capable of fitting several GPUs.* [[Infrastructure:Sunway|sunway]] and a SuperMicro server were all transferred to WUVT. Older hosts have either been thrown out or given to members.

Most other VTLUUG-owned servers are currently stored in Ali's basement, with the exception of See [[infrastructureVTLUUG:sunway|sunwayStrategic_plan]]and a SuperMicro server, which were all transferred for things we plan to WUVTdo in the future.

Because VTLUUG infra no longer has IPv6 access, we are limited by the IP addresses assigned to usWe currently have some services with public IPv4 address, and what wecan get through DHCP from ECE. As a consequence, all services which do not need to hosts have a global IP should moveto 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 anused. ethernet port on cyberdeliaIn 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.

 All vtluug websites are run on nginx on milton[[Infrastructure:Sczi|sczi]]. These sites are currently functional:

* 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]. It is alsounlikely that nginx will start properly because of weird dependenciesletsencrypt certs.

 It currently appears that the The main vtluug VTLUUG page (mostly written in php), is or was managed scraped fromthe [[w:Internet Archive|Internet Archive]] and added created as a github page at[https://vtluug.org/atrium Drupalgithub.io vtluug.github.io] as a backend, but for that to function, mysql needs to be running. uWSGI, django, and PHP appear 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 availableto provide more information on the set-up.

 The wiki currently runs fully on MediaWiki hosted on nginx (as opposed to the default include using a [https://github.com/vtluug/mediawiki-docker modified version of apache2,demanded by the Debian package)official mediawiki docker image]. Postgres is used for You can auth with the database managementadmin account, AFAIK, and authenticationis through [[User:wiki-admin|wiki-admin]] or a Google account. See note on [[Main_page]] about why LDAPisn't working yet. MediaWiki is a dated git version from the stablerepository, as of March 2016, howeverupdating is more complicated than a git pull

All but disabled currently, due to spam. Runs on MediaWiki ==== Linx ==== Uses [[User:andreim|aam]]'s [https://github.com/andreimarcu/linx-server linx], and is an identical implementation to his site[https://linx.li linx.li]. One of the few sites with a complete startup script. The maintenance is currently the responsibilityof aam, however this is subject to change. === Historically === Beyond these, we have data and nginx configurations for these (deprecated) sites, whichwere previously hosted on milton: ==== Needs Restoration ====

* [https://github.com/mutantmonkey/foodforus foodfor.vtluug.org ] - For [[Wadsworth]]'s .pickfood and .foodvote commands. This is [[User:Timelord|jpo's]] fault.* tahoe.vtluug.org - [[user:mjh|mhazinsk's ]] Tahoe-LAFS grid

* [https://github.com/vtluug/campusmap map.vtluug.org ] - [[Openstreetmap|OSM]]* vtbash.org - based map of VT QDB* users.vtluug.org - member hosting of acidburn home directories

===Historically = 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.* 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* uniluug.org - deprecated project* security.ece.vt.edu - REDACTED* wargame.vtluug.org - vtluug's wargame pre-vtcsec* munin.vtluug.org - former attempt at monitoring* webchat.vtluug.org - channel webchat; version of the service still runs on the vtluug website as an embeded frame from freenode's website* cdn.vtluug.org - member website* randynance.info - member website* jessicaandchristopher.net - member website* vtcybersecurity.org - member website from pre-csec days

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 See [[Dead_projects]] for this still exist.historic information

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> 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|AamStrategic_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 because account creation was disabled toprevent spam. This needs to be addressed by adding captchas which are Blacksburg-specific, limitingaccount creation access to local IP addresses, '''or''' enabling some form of LUUG-managed accountcreation. One suggestion was using CAS/Login future goals involving web services to authenticate, however that makes it difficultfor Blacksburg residents 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.
