This s/w is no longer available on the web. This is what I used to learn event driven programming via David Mazieres' cs240d class. I thought that was one of the best classes I ever had.

SFS (Self-certifying File System) is a secure, global network file system. SFS names file systems by public keys. Every remote file server is mounted on a self-certifying pathname--a directory of the form /sfs/LOCATION:HOSTID, where LOCATION is a DNS hostname and HOSTID is a cryptographic hash of a public key. This naming scheme allows for completely decentralized control--anyone can create a file server, and any user can access any file server from any client. Various key management schemes can be built on top of SFS using symbolic links to map human-readable names to self-certifying pathnames.

SFS should run with little or no modification on any operating system that supports NFS3. We have at varoius points run SFS on OpenBSD, FreeBSD, Linux, Solaris, and Digital Unix. SFS also compiles and runs under MacOS X, but see the file INSTALL.darwin in the distribution for more information on this.

This release of SFS should be considered pre-alpha. Though to-date SFS has been remarkably stable, the SFS protocols and interface will change in the future. Though we will make some effort to maintain compatibility, we cannot guarantee complete compatibility with future versions.

More documentation can be found in the SFS info pages in the doc subdirectory, or at the SFS web site http://www.fs.net/.
