Operational structure of Tachanka!

The technical and operational structure of Tachanka works at several levels. We attempt to describe some of them on this page.

Colocation level, configuration and maintenance of hardware

Tachanka maintains a couple of servers distributed throughout data centers around the world. Most of these servers are configured to host virtual private servers (VPS), currently implemented using linux-vserver. This allows for complete isolation of separate software systems with the lowest possible hardware overheads. In other words, a high emphasis is placed on security whilst optimising the performance of the services we provide.

Server level, configuration and maintenance of host systems

The host collective, Tachanka, is made up of members of the many involved collectives. Each of us knows at least two others involved; there is a strong web-of-trust, with the Tachanka servers acting as a cross-pollination ground for inter-activist education and support. The base systems are maintained with a minimum of services and a tight security policy; all systems run Debian GNU/Linux.

Virtual server level, configuration and maintenance of guest OS's (VPS)

Tachanka runs a number of the virtual private servers in order to provide shared services for the other machines. However, the primary aim of Tachanka is to enable groups that otherwise would not be able to afford a dedicated server to run their own, individualised virtual private servers in a secure fashion.

Service level and hosted applications

DNS

Tachanka hosts caching name services for the hosted virtual private servers, as well as authoritative name services.

Mail/Lists

  • Email is currently not provided by Tachanka, but it is possible to get accounts via some of the collectives involved: look at aktivix for further details.
  • Lists are also provided on one of the VPS. We are able to provide individual lists through some of the collectives involved (aktivix). If you wish to provide multiple lists, it may be possible to set them up under a new domain name. Please contact us for more information.
  • Encrypted mailing lists are another possibility; please contact us if you require more information.

Drupal

One of the VPS is providing a Drupal farm. This is currently being used to host a few small Indymedia web sites.

MySQL/Databases

MySQL databases for the various content management systems are provided securely via a VPS on an internal interface only; there are daily, encrypted backups, and the data is only accessible to the application which is using it.

Munin and Nagios Monitoring

All VPS's are monitored by the Tachanka collective via munin graphs and nagios service monitoring. Tachanka also provides munin monitoring for some other collectives.

Tor

Tachanka believes that anonymous access to the internet is a right, rather than a privilege, hence we provide a Tor anonymous proxy server.

APT repository proxy cache server

For faster software downloads and in order to reduce bandwidth usage and to cut costs, all virtual private servers hosted with Tachanka have access to a locally hosted APT package repository.

Static html mirror server

Tachanka supports the Indymedia network by hosting some mirrors of different sites.

This server also hosts some websites of individuals and small projects.

Other information

There are several pages on this website which Tachanka members have started working on that relate to some of our technical services. Currently, the following may be of use:
