                     Announcing the Availability of the
                             Coda Distributed
                                Filesystem
                                   for
                              BSD Unix Systems
     
             Coda is a distributed file system like NFS and AFS.  It is
     freely available, like NFS.  But it functions much like AFS in being a
     "stateful" file system.  Coda and AFS cache files on your local
    machine to improve performance.  But Coda goes a step further than AFS
    by letting you access the cached files when there is no available
    network, viz. disconnected laptops and network outages.  In Coda, both
    the client and server are outside the kernel which makes them easier
    to experiment with.
    
    To get more information on Coda, I would like to refer people to
            http://www.coda.cs.cmu.edu
    There is a wealth of documents, papers, and theses there.  There is
    also a good introduction to the Coda File System in
            http://www.coda.cs.cmu.edu/ljpaper/lj.html
    
    Coda was originally developed as an academic prototype/testbed.  It is
    being polished and rewritten where necessary.  Coda is a work in
    progress and does have bugs.  It is, though, very usable.  Our
    interest is in making Coda available to as many people as possible and
    to have Coda evolve and flourish.
    
    The bulk of the Coda file system code supports the Coda client
    program, the Coda server program and the utilities needed by both.
    All these programs are unix programs and can run equally well on any
    Unix platform.  Our main development thrust is improving these
    programs.  There is a small part of Coda that deals with the kernel to
    file system interface.  This code is OS specific (but should not be
    platform specific).
    
    Coda is currently available for several OS's and platforms:
            Freebsd-2.2.5: i386
            Freebsd-2.2.6: i386
            Freebsd -current: i386
            linux 2.0: i386 & sparc
            linux 2.1: i386 & sparc
            NetBSD 1.3: i386
            NetBSD -current: i386
    The relevant sources, binaries, and docs can be found in
            ftp://ftp.coda.cs.cmu.edu/pub/coda/
    
    We intend to come out with new Coda releases often, not daily.  We
    don't want to slight any OS/platform not mentioned above.  We are just
    limited in our resources as to what we can support internally.  We
    will be happy to integrate OpenBSD support as well as other OS
    support.  Also, adding platform support should be relatively easy and
    we can discuss this.  The only difficulty is that Coda has a light weight
    process package.  It does some manipulations in assembler which would
    have to be redone for a different platform.
    
    There are several mailing lists @coda.cs.cmu.edu that discuss coda:
    coda-announce and linux-coda.  We are going to revise linux-coda to be
    OS neutral, since it is mainly Coda we want to discuss.  We appreciate
    comments, feedback, bug reports, bug fixes, enhancements, etc.
