== Physical Infrastructure ==
=== NFS Hosts ===* [[Infrastructure:Dirtycow|dirtycow]] - Primary NFS server, 8x2TB raidz2 array* [[Infrastructure:Cyberdelia|Cyberdeliacyberdelia]] is the only connected physical machine right now. It contains 48 GB of memory with 4 ethernet interfaces; only eth4 is connected and is attached to br0. All hosts are on the ECE network behind router.ece.vt.edu- OFF, a gateway featuring ARP proxying but no IPv6. For global DNS changes under ece.vt.edu7x1TB raidz2 array, server room access, and getting hosts added to the ARP proxy, contact Branden McKagen.sitting on shelf instead of shelf
=== VM Hosts ===* [[Infrastructure:Meltdown|meltdown]] - Primary VM/docker host* [[Infrastructure:Spectre|spectre]] - Secondary VM/docker host, for example user VMs === Router ===* [[Infrastructure:Shellshock|shellshock]] - 3 disk RAID1 array All hosts are on our own 1 Gb/s port with [[Infrastructure:Joey|joey]], a gateway featuring ARP proxying, and full delegation of the 2607:b400:6:cc80/64 prefix. Virginia Tech has started blocking inbound ports 22 and 3389 and outbound port 25 at the campus border, in a move some are [[User:echarlie|echarlie]] is calling [[gp:Cyber Auschwitz|Cyber Auschwitz]]. 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. See [[VTLUUG:Strategic_plan]] for things we plan to do in the future.
== 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/24 16 subnetand an IPv6 address assigned via SLAAC. In the future, it may [[Infrastructure:IPsec|VPN]]/[[Iodine]] should be used. In theory, services can be wise to bridge this network to an ethernet port provided via a hidden service such as [[w:Tor|Tor]], but that introduces other complications.Alternately, services can require use of the [[Infrastructure:IPsec|VPN]] on cyberdelia[[Infrastructure:Acidburn|acidburn]],[[Iodine]], or [[Secure Shell|ssh tunnelling]], so that although all of these limit usage to members with a switch can shell account.All of these have the benefit of NAT transversal, however. == Services ==''Further information: [[:Category:Services]]'' * [[Infrastructure:Acidburn|acidburn]]** Shell server** [[Email]]** [[Wadsworth]]* [[Infrastructure:Chimera|chimera]]** FreeIPA* [[Infrastructure:Sczi|Sczi]]** Website*** Wiki*** Main Page*** linx*** [https://bash.vtluug.org vtbash]* [[Infrastructure:Dirtycow|dirtycow]]** Storage for all primary services** NFS - ZFS pool name is cistern* [[Infrastructure:Meltdown|meltdown]]** VM host for above services [[Infrastructure:Acidburn|acidburn]] and the website ''must'' be used accessible through real services, and it is preferable other hosts are too. This means we must use our public IPv4 & IPv6 Addresses allotted by ECE. == Website details ===== Current Setup ===All vtluug websites are run on nginx on [[Infrastructure:Sczi|sczi]]. These sites are currently functional:* gobblerpedia.org* hokieprivacy.org* vtluug.org* wiki.vtluug.org (redirects to network our other vtluug.org/wiki/)* bash.vtluug.org* vtluug.org/users/~$user All of these sites exclusively allow for the use of TLS connections. All servicesuse automatically updatedletsencrypt certs. When we have rackspace  ==== Main Page ====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]]. ==== 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. ===== Gobblerpedia =====Runs on the same Mediawiki instance as this wiki. Similarly to do soLUUGWiki, VPNonly Google accounts or the admin user are supported logins. === 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 .foodvote commands. This is [[User:Timelord|jpo's]] fault.* tahoe.vtluug.org - [[Iodineuser:mjh|mhazinsk's]] access Tahoe-LAFS grid* git.vtluug.org - git hosting; previously a redirect to gitweb with gitosis as the internal network will be necessarySSH backend* gitweb.vtluug.org - git hosting; previously gitweb* [https://github.com/vtluug/campusmap map.vtluug.org] - [[Openstreetmap|OSM]] based map of VT === Historically === See [[Dead_projects]] for historic information === Goals ===See [[VTLUUG:Strategic_plan#Web_Services]] for future goals involving web services
