Welcome to ACKspace; a hackerspace located in Heerlen, The Netherlands.

A hackerspace is a place where people get together, socialize, share knowledge, tinker and build stuff.

In order to make this possible we have a collection of tools, (useful) stuff, work area and a lounge where we can relax and discuss our favorite games.

xopr 5 April 2017: I'm working on a new system to replace the current virtual machine


VoIP system with its involved servers

new system

The current system is lacking functionality and needs revisioning. Currently, the trunks that register with the extensions, don't work. When they do, participants registered to the (public) VoIP system are able to directly dial an internal space extension.

current status

  • SpacePhone ENUM number
  • Dutch language for IVR
  • spacestate information logic
  • Every room has its own phone
  • possible to dial ackspace.nl sip addresses (info, conf, [username])

todo

  • Create new (vanilla) VM on new server
  • update/extend IVR menu
    • mention the space state before actually answering (183:progress)
    • start with a brief menu, but give more info on demand
  • add support for Cisco 7900 phones (Cisco phone deployment)
    • need to put an interface on a different VLAN
    • update all switches to offer the same VLAN
    • add TFTP and add the firmware + configs
    • update the DHCP (option 66 or 150)
    • update dialstring to both signal SCCP and SIP
  • update public SIP addressing (dedicated public IP or a VPS redirect)

wishlist

  • multilingual IVR
  • enable fax/modem detect
  • enable 2600 toying option
  • key people (1333)
  • Add a HAM autopatch system to the telephony system so sip phones and amateur radio are interconnected
  • simple intercom service
  • number lookup script
  • various participant registrations (see #extensions)
  • some scripting to ease life and add some nifty features
  • trunking over VPN
  • install PoE blade or smaller PoE switch (might want to choose for regular power supplies)

extensions

This is the list of registered extensions. If you want to register your own extension, let Xopr know. For available extensions, refer to the #dialplan

2) not available due to IP restrictions

To do: (valet) park, call intercept, call return, redial, paging


Interactive Voice Response

The concept for the new IVR menu will have something like this:

ack_main and ack_info (are the same, but with different spoken texts)

  • 1[059]\d: direct dial extensions
  • 2 switch to English language
  • 3 switch to Dutch language
  • 5 direct dial ring group
  • 6 dial key persons, enable voicemail detect and use time schedule
  • 7 go to conference rooms
  • 8 go to menu ack_extra
  • 9 go to menu ack_info
  • 0 go to menu ack_directory

ack_extra

  • 1 more info on space state (time of toggle)
  • 2 speak out telephone number and/or IP address
  • 3 listening rooms
  • 4 extended time service
  • 5 contact location abroad (when online)
  • 6 echo test
  • 8 call test setup
  • 9 repeat this menu
  • 0 go back
  • * go to main menu

ack_directory

  • 100 for slACKspace (lounge)
  • 101 for hACKspace (workshop)
  • 109 for DECT (wireless)
  •  ??? for chairman
  •  ??? for secretary
  •  ??? for treasurer
  • 1(all other public extensions)
  • 5 call anyone
  • 8 lookup by typing first three characters using keypad
  • 9 repeat this menu
  • 0 go back
  • * go to main menu


history

Chaos Communication Camp 2011

The CCC Binary Voice Radio telephony server was a mixed success. Actually, it was a disaster:

  • The visual ring indicator circuit didn't trigger the optocouplers so that was the first thing to fail.
  • a lot of power failures which caused a lot of downtime and eventually database corruption
  • the DECT system was getting too complex for the simple phones we've modded for field reporting (Technical clarification came from one of the Eventphone key people who explained that the antenna register on cheap phones was too small to identify them all). Besides that, it looked like the cabling had short-circuited because the 9v battery didn't have any oomph left to generate amplified audio.
  • wifi had a hard time maintaining the links and coverage wasn't 100% so the wifi field reporter wasn't a good alternative
  • last but not least: the public IP addressing threw a spanner in the works and the server went limbo.

The server's database went corrupt, and after a restore, it didn't match the regular config files. I got it semi-working after it was far too late to make it useful to the studio. Also, after I got it to work, it wouldn't register correctly to the Eventphone trunk and we only got to call the editorial room (2781|BVR1) via DECT twice or so. Despite all that stress, it was promising, so better luck next time.


Open door day 2011

For the open door day, I set up a stand-alone test system with two Cisco 7940s, a FxS/FxO and dual FxS ATA, which included some softclients.

The phones were successful in a rough field test on the open door day, connected to a FreeSWITCH exchange and two ATAs which provided connections to two additional analog handsets. The field test proved reliable enough and a great platform for some hilarious phone pranks.

The Cisco phones had a menu where you could view a 2 bit grayscale snapshot of the two space cams, and you were able to switch some outlets. People were allowed to navigate the configs and exploit functionality and LuckY sniffed and replayed audio over a wifi link.

Other events


connecting various devices to ACKspace VoIP

connecting the Fritz!Box

  • Note that the Fritz!Box is pretty quirky regarding SIP: it can't handle a 407-unauthorized correctly when in router mode (which is needed to differentiate between public and internal calls). xopr had more success setting the device as a flat switch and putting it behind a generic router (tested with a ZyXel).
  • It also doesn't like usernames; you have to start with a number and change it afterwards.
  • It does seem to have more ring power than the tested ZyXel, though.

connecting the Linksys PAP2T

The following settiings are needed:

  • TBD

penningmeesterschap stichting ACKspace

Stichting ACKspace, omgeving Heerlen

ACKspace is de zuidelijkst-, en daarmee ook hoogstgelegen hackerspace die de Nederland kent.

Statutair is ons motto: Het ondersteunen en faciliteren van de internationale en multiculturele "ACKspace community" en het hierdoor verbeteren van de wereld door heroverweging en op creatieve wijze aanpassen van de technologie; het verrichten van alle verdere handelingen, die met vorenstaande in de ruimste zin verband houden of daartoe bevorderlijk kunnen zijn.

Een belangrijk aspect binnen de stichting is sociale omgang waarbij techniek centraal staat.

Functieomschrijving

  • je coördineert en monitort het financiële gedeelte binnen de stichting
  • je draagt bij aan het bestaan van de space
  • je krijgt meer zeggenschap over de groei van de space

Wij vragen

  • je neemt initiatief en kunt zelfstandig en flexibel werken
  • je hebt affiniteit met hackerspaces, hacker events en/of ACKspace in het algemeen
  • ervaring met bestuurschap is een pré, maar beslist geen eis; zie aanvullende informatie

Dienstverband

Een dienstverband voor onbepaalde tijd.

Werktijden

De vacature zal neerkomen op enkele uurtjes vrijwilligerswerk per week. Hierbij is te denken aan een keer per maand de inkomende transacties monitoren, een keer per kwartaal een financieel overzicht uitwerken. De rest van het bestuur kan de penningmeester hier in ondersteunen.

Tegemoetkoming

Gezien ACKspace een stichting is met minimaal budget staat tegen de functie van bestuurslid geen beloning tegenover, maar statutair is vastgelegd dat deze wel recht heeft op vergoeding van de door hen in de uitoefening van hun functie gemaakte kosten.

Aanvullende informatie

Momenteel heeft het bestuur gezamenlijk zo'n 18+ jaar ervaring in de huidige vorm, en kan een nieuwkomende penningmeester makkelijk begeleiden in het uitoefenen van deze taak.

Voor meer informatie en/of inschrijving, neem vóór 16 april contact op met info <apenstaartje> ackspace <punt> nl
Schoonmaakbord


Het schoonmaakbord was opgezet met het idee om (een deel van) de space soepel draaiende te houden.

Waarom niet meteen dat concept doortrekken naar alles wat bijdraagt aan een betere space? Boodschappen gedaan? Handig space project opgezet? Aan infra gewerkt? .. ? Vinkje erbij! Mensen verdienen erkenning voor hun bijdrages! Go team go! :P

De volgende zaken dragen bij aan een schone space en aan je collectie vinkjes (deze moet nog verder uitgeschreven worden):

  • Stofzuigen
  • Afwassen
  • Ramen schoonmaken
  • Boodschappen gedaan
  • Handig spaceproject opgezet
  • Aan infra gewerkt
  • ...
