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is intended as a scratch pad ofsorts for organizing infrastructure changes, since [[Infrastructure:Log]] is incredibly out of date, andthere are a lot of details which must be sorted out before major infrastructure changes can be made.

=== NFS Hosts ===* [[Infrastructure:Dirtycow|dirtycow]] - Primary NFS server, 8x2TB raidz2 array* [[Infrastructure:Cyberdelia|Cyberdeliacyberdelia]] - OFF, 7x1TB raidz2 array, sitting on shelf instead of shelf === VM Hosts ===* [[Infrastructure:Meltdown|meltdown]] - Primary VM/docker host* [[Infrastructure:Spectre|spectre]] is the only connected physical machine right now- Secondary VM/docker host,for example user VMs === Router ===besides * [[Infrastructure:Temp88191Shellshock|our routershellshock]]. It contains 48 GB of memory- 3 disk RAID1 array with 4 ethernet interfaces; only eth4 is connected and is attached to br0. All hosts are on our own 1-gbit Gb/s port with[[Infrastructure:Temp88191Joey|temp88191joey]], a gateway featuring ARP proxying, and partial NDP proxying.For global DNS changes under ece.vt.edu, server room access, and getting hosts added to full delegation of the ARP proxy,contact [mailto2607:b400:jkh@vt.edu John Harris] or [mailto6:rdehart@vt.edu Roddy Dehart]cc80/64 prefix.

When deploying new hosts, make ssh listen on both 2222 and 22. [[Infrastructure:Acidburn|Acidburn]] currently listens on 443 3128 as well.

All other VTLUUG-owned servers are currently stored in === Other hosts ===* [[userInfrastructure:pewWood|pewWood]]is sitting in our rack turned off because we don's apartment, with the exception t have a use for it currently. It is in a 4U case capable of fitting several GPUs.* [[infrastructureInfrastructure:sunwaySunway|sunway]]and a SuperMicro server, which were all transferred to WUVT. The list of these machines includes [[Infrastructure:Wood|Wood]],and a variety of other servers, including our old LXC Older hosts and the old mirrorhave either been thrown out or given to members.

See [[GoalsVTLUUG:Strategic_plan]] for things we plan to do in the future.

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. In theory, services can be provided via a hidden service (read: such as [[w:Tor|Tor]]), but that introduces other complications.Alternately, services can require use of the [[Infrastructure:IPsec|VPN]] on [[Infrastructure:acidburnAcidburn|acidburn]],

The main VTLUUG page was scraped from the [[w:Internet Archive|Internet Archive]] and added created as a github page at[https://vtluug.github.io vtluug.github.io], and is reverse-proxied through [[Infrastructure:Sczi|sczi]].

 The wiki currently runs fully on MediaWiki hosted on nginxusing a [https://github. Postgres is used for com/vtluug/mediawiki-docker modified version of the database and authenticationis through LDAPofficial mediawiki docker image]. MediaWiki is running You can auth with the current stable version as of March 2017admin account, courtesy hard work by[[userUser:pewwiki-admin|pewwiki-admin]]or a Google account. See note on [[Main_page]] about why LDAP isn't working yet.

Runs on the same Mediawiki instance as this wiki, with its schema in the same Postgres database. Currently, you can authwith LDAP, pre-existing accounts, or a Google account in the VT hosted domain. ==== 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, pending his retaining root access on sczi. === Historically === Beyond these, we have data and nginx configurations for these (deprecated) sites, whichwere previously hosted on milton: ==== Needs Restoration ====

* [https://github.com/vtluug/campusmap map.vtluug.org ] - [[Openstreetmap|OSM]] (gobblerpedia still relies on this)* vtbash.org - based map of VT QDB (recently a static version was functional)* 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 [[uniluug]]* 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. This should be disabled.* 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 aWordPress instance. The files for this still exist. Much of the original django deployment was highly dynamic, with an identi.cafeed, automatic calendar updates, and other features. 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. A static version of vtbash.org is hosted at [https://vtluug.org/bash/index.html https://vtluug.org/bash/index.html]. 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.<!--When? I thought it was always users.vtluug.org? -- I don't think it matters. the point is that this ''was'' a feature--> 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. PostgreSQL tables exist on milton for foodforus, jandc, mediawiki, mewsblu, sharedwiki, uniluug, vtluug_wiki, and wargame_bbs. Moreresearch is necessary to determine what these are for. There are also a collection of mySQL databases on milton which maybe desirable to archive and store. === Considerations for the future === It would be preferable to keep all existing sites functional. [[user:andreim|Aam]] suggested the use of [https://caddyserver.com/ caddy]to replace nginx, especially on static sites, because it provides automatic letsencrypt. Most likely, this will not be used, though,in favour of manually configuring letsencrypt (because caddy is not in the repositories). 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. ==== TLS 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. The version of OpenSSL on milton does not support TLSv1.1 or TLSv1.2 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 sczi. 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 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. [[user:Echarlie|echarlie]]would like a simple static site with some clean CSS, to avoid the clusterf*ck that is re-enabling uwsgi at thecurrent time.

''Main article: [[Infrastructure:Network]]'' VTLUUG currently has DNS with namecheap, however all domains have been re-registered with gandi undervtluug.net. Message officers for access (please don's own account, to replace the mixture of mutantmonkey-holdings and vtluug-held domains on multipledifferent registrarst be scared :D).

An important limitation of the HE tunnel is that they block port 25 by default. https://linx.vtluug.org/ips1.txt {| class="wikitable"!globally addressable!ECE DNS!Name!fucntion!internal address|-| 128.173.88.78| luug.ece.vt.edu.| [[Infrastructure{:sczi|sczi]]| New webserver| <!--10.99.0.27??--> 10.99.0.150 (Currently DHCP)|-| 128.173.89.244| luug0.ece.vt.edu| [[Infrastructure:cyberdelia|cyberdelia]]| VM Host| 10.99.0.1|-|128.173.89.245 | luug1.ece.vt.edu. | [[Infrastructure:acidburn|acidburn]]| shell server.
