AFS for Linux

Installing / Configuring AFS on Linux

The School of Informatics uses OpenAFS for its network filesystem. This page describes how to install and configure OpenAFS on Linux. The simplest instructions for installation differ by distribution, though the basic idea and steps will usually be the same. If your distribution isn't listed, it's worth looking at a similar distribution for the basic outline.

Client Versions

For security reasons we do not support the use of Single-DES encryption. This means that AFS users must have a version of the client which can use stronger forms of encryption. If you are still using the old stable 1.6 release of AFS, these are the minimum required versions for various Linux distributions:

  • Debian
    • Debian 7 obsolete stable (wheezy) - 1.6.1-3+deb7u7
    • Debian 8 current stable (jessie) - 1.6.9-2+deb8u5
  • Ubuntu
    • 14.04 LTS (Trusty Tahr) - 1.6.7-1ubuntu1.1
    • 16.04 LTS (Xenal Xerus) - 1.6.15-1ubuntu1
  • Scientific Linux
    • 6 - 1.6.20-256.sl6
    • 7 - 1.6.20-256.7

If your version is older than that listed above you must use the package manager (e.g. yum or apt-get) for your system to apply the necessary update.

If you are using the current 1.8 stable release of OpenAFS (and we strongly recommend that you do), you must use version 1.8.7-0 or later to avoid being affected by the epoch bug of early 2021.

Not all Linux distributions provide packages for openafs. If you are using Redhat or Fedora you can download RPMs for the latest version from the OpenAFS website. You must use at least version 1.6.5.
