Welcome to OFTC!

The Open and Free Technology Community aims to provide stable and effective collaboration services to members of the community in any part of the world, while closely listening to their needs and desires.

OFTC was founded at the end of 2001 by a group of experienced members of the Open Source and Free Software communities aiming to provide these communities with better communication, development, and support infrastructure.

OFTC is a member project of Software in the Public Interest, a non-profit organization which was founded to help organizations develop and distribute open hardware and software.

You can reach the OFTC IRC network by using a traditional IRC Client of choice, or by the WebChat that we provide. The webchat enables you to connect to the network and chat directly from within your browser.

If you have support requests regarding the operation of the network please stop by #oftc or email support@oftc.net. We welcome issues and pull requests on our GitHub projects, especially on the issue tracking repository.

Connection Details:

  • ircs://irc.oftc.net:6697 for SSL (alternative port: 9999), IPv4 and IPv6.
  • irc://irc.oftc.net:6667 for non-SSL (alternative ports: 6668-6670, 7000), IPv4 and IPv6.
  • SSL is supported on all of our servers. The server certificates are signed by the Let’s Encrypt certification authority.
  • See CertFP for how to configure client certificate-based NickServ identification.
  • If you need to force IPv4, connect to ircs://irc4.oftc.net:6697.
  • We offer a WebChat service (also via the boxes at the top of this page).
  • Use of Tor is permitted.


September 2016

  • We have completed the upgrade to oftc-hybrid 1.7.
  • OFTC now supports modern DHE and ECDHE cipher suites to offer perfect forward secrecy for SSL/TLS connections. Thanks to Alexander Færøy for the patches!
  • NickServ’s AJOIN feature is now fully available again.
  • We welcome new staff member dwfreed on board!
  • The minimum length of acceptable nicknames for registration in NickServ has been lowered to 2 characters. Previously the minimum length was 3 characters.
  • In self-referential news, news items are now also available as Atom/RSS feed .

July 2016

  • OFTC is now featuring full DNSSEC support. Both the oftc.net and geo.oftc.net zones are signed and verifiable from the DNS root. Additionally, TLSA (aka DANE) records allow verification of the individual SSL certificate fingerprints of our IRC servers.

    On related news, our old oftcdns load-balancing for IRC servers based on Python Twisted has been replaced by a newer implemetation based on bind9 and dynamic DNS updates.

  • Adding new AJOIN channels via NickServ is currently disabled. The current implementation allows to circumvent channel bans. AJOIN will be reenabled once this is fixed.

April 2016

  • We have completed the move to SSL certificates issued by the Let’s Encrypt project. These certificates should remove the need for users to manually install any CA certificate files. Please drop by on #oftc or mail support@oftc.net if you have any troubles with the new certificates.

    OFTC would like to thank Software in the Public Interest for providing us with certificate services over the last years, when non-commercial SSL certificates were a scarce resource.

    Update 2016-04-19: Users who have hard-coded paths to CA files in their client config will need to update or remove that config. Especially irssi users are hit by this problem. Removing ssl_cafile from ~/.irssi/config (but leaving ssl_verify in place) should fix it. (Note that /reconnect does not use the new config, use /reload /disconnect /connect instead.)

March 2016

  • The CA used to sign our IRC server certificates, SPI, has been removed from Debian’s (and other’s) ca-certificates package. This means users will now be seeing “self-signed certificate in certificate chain” errors or experiencing similar problems with SSL connections.

    We are moving to Let’s Encrypt certificates, but have yet to complete testing our processes.

    To work around the problem until we have new certificates, manually import the spi-cacert.crt certificate into your system’s or IRC client’s trust store.

February 2016

  • The OFTC website www.oftc.net finally supports SSL, a long-requested feature.
