Folks...
This note is to bring you up to date on the developments in the
grand.central.org (GCO) facility for user contributed software.
Primarily, some major pre-packaged software distributions have been
added. Also, the klogm program is available, an improvement to mklog
multiple authentication tool.
The /afs/grand.central.org/darpa/usr/contrib/dist directory has been
created to house pre-existing software distributions which are now (or
soon will be) visible through GCO. There are currently three
subdirectories in the dist subtree:
1. mach - This is the Mach microkernel source distribution from
the CMU Computer Science Department. Its mach_3 subdirectory
contains the Mach 3.0 (MK58) system. The READ_ME file there
explains what exactly may be found. Roughly, it contains the
complete Mach source tree, change logs from the previous version
(MK42), and compressed tar files of the sources (suitable for
FTPing). My thanks go to Mary Thompson at CMU, who allowed me
to make this software distribution visible via GCO. In fact,
the GCO ``distribution'' is simply a symlink into the location
in the cs.cmu.edu cell where the software actually resides.
2. cmucontrib - This is the sum of the CMU /usr/contributed
collection, basically the full set of programs that have been
contributed by the general CMU community. Carnegie-Mellon
University has developed a sophisticated mechanism by which they
are able to accept, manage, and advertise software contributed
from its own users. As with the Mach collection above, the GCO
view of CMU's user-contributed software is implemented as a
symlink into its andrew.cmu.edu place of residence. My thanks
go to Mark Held and Wallace Colyer (my primary contacts
regarding this project), who have taken time to discuss their
system with me.
3. abm - In the near future, this directory will provide the
Andrew Benchmark, the file system performance metric which has
been used to derive numbers regarding distributed systems such
as AFS and NFS. It is currently *NOT* publicly viewable. There
are some points which must be finalized regarding how its usage
may be tracked. An announcement on this same channel will
appear shortly, describing the set of conditions on its use. My
thanks to Mahadev Satyanarayanan for allowing this GCO
distribution channel to be used.
Along with these pre-packaged solutions, a derivative of the mklog
program has been written. This new klogm script takes a list of
user@cell identities and performs AFS authentications for them in
parallel. The password used must be identical for all listed
identities. For example, consider an identifier file containing the
following lines:
erz@transarc.com
erz@grand.central.org
ezayas@yet.another.site
Klogm accepts the password from the user and then performs the
authentication RPCs for the above three cells in parallel. As usual,
full documentation on klogm can be found in
darpa/usr/contrib/doc/klogm.doc.
Again, if anyone has interesting software or documents which they would
like to see appear in this forum, please send me mail and it will be
quickly installed. Keep those cards and letters coming in, and tell
your friends!!
Happy sharing!
Ed.
