Welcome to the home of OpenAFS

What is AFS?

AFS is a distributed filesystem product, pioneered at Carnegie Mellon University and supported and developed as a product by Transarc Corporation (now IBM Pittsburgh Labs). It offers a client-server architecture for federated file sharing and replicated read-only content distribution, providing location independence, scalability, security, and transparent migration capabilities. AFS is available for a broad range of heterogeneous systems including UNIX, Linux, MacOS X, and Microsoft Windows

IBM branched the source of the AFS product, and made a copy of the source available for community development and maintenance. They called the release OpenAFS.

20-Mar-2007 - OpenAFS Security Advisory 2007-001

Unix clients in OpenAFS versions before 1.5.17 and 1.4.4 allow a potential privilege escalation via setuid functionality which can be enabled by the client administration but is enabled by default for the client's local cell. To avoid this issue, 1.5.17 and 1.4.4 have been issued with setuid disabled by default in all cases.

28-Dec-2006 - OpenAFS Elders announce "No More DES" roadmap

AFSv3 was designed and implemented during the late 80s and early 90s when the state of the art in distributed computer authentication and data confidentiality was to use Kerberos 4 and the United States' Data Encryption Standard (DES). Over the last two years the U.S. National Institutes of Standards and Technology (NIST) has withdrawn the DES standard and MIT has announced the end of life of Kerberos 4. In response, the OpenAFS Elders have approved a roadmap to transition from DES to stronger ciphers which includes the deprecation of the OpenAFS kaserver.

6-Dec-2006 - pam-afs-session 1.0 released

pam-afs-session is a PAM module intended for use with a Kerberos v5 PAM module to obtain an AFS PAG and AFS tokens on login. It puts every new session in a PAG regardless of whether it was authenticated with Kerberos and runs a configurable external program to obtain tokens. It supports using Heimdal's libkafs for the AFS interface and falls back to an internal Linux-only implementation if libkafs isn't available.
