The most recent OpenBSD release is 2.1. You can find these files in OpenBSD/2.1 on each listed FTP server.

Binary Snapshots:

As well, snapshots will be made available from time to time on the ftp mirrors. The snapshots are available on each of the FTP servers listed below, typically in the directory OpenBSD/snapshots. If you plan to use a snapshot, you should also read the general description about OpenBSD snapshots.

The file structure of each FTP server is roughly:

• .../OpenBSD/2.1/
  -- where you find our most recent release. X11 is included if possible.

• .../OpenBSD/snapshots/
  -- for major architectures, we tend to build mini releases of unknown stability and quality about every month or so.p

• .../OpenBSD/src/
  -- a checkout of our daily source tree for those who want to access individual files. Normally we recommend the use of CTM or AnonCVS instead of mirroring this location.

• .../OpenBSD/tools/
  -- various other little bits..

If you add a new FTP mirror site, please contact the FTP maintainer.
