[ProgSoc] Sutekh loginable (not final revision yet)

[Telford Tendys <telford@nospam.progsoc.uts.edu.au>]

OK, I have a hand-done arangement where normal users can log
in to Sutekh. The SCSI card is still to be replaced with a better
one and the passwords are not NIS but just copied off the NIS
server (via encripted scp naturally). Basically NIS has a lot
of promise and if it lived up to all the things that the man
page says it can do it would be great, in practice it is complicated
and confusing and (the way it is working at Progsoc) unreliable
and insecure, also NIS is very much associated with the Sun way
of doing things and not well supported under Linux (Raz may
argue the point here).

Sutekh is running shadow passwords and login can only me made
with encripted links using either ssh (not ssh2) or else telnet-ssl.
This means that no user can look at other users passwords (even
in scrambled form) nor can a line-snooper be used to extract
user information.

Unfortunately, it still doesn't have any mail or home directories
so you can just go to /export/owls/tmp or /export/rams/tmp and
create yourself a directory. Compilers and various languages are
working (egcs, perl, python, etc) and most importantly, I have
compiled and installed version 3 of berkeley spice.

For people interested in circuit design and analysis, have
a look at /export/owls/tmp/spice_test where I have some sample
files and a README explaining how to get started using berkeley
spice. You will probably have to find an X11 terminal somewhere
and come in using ssh so that you can use the graphical plotting
of results. Even though the disc is slow, the CPU is OK so spice
runs are quite quick (quicker than ftoomsh but that is not a fair
comparison since ftoomsh has the FORTRAN version 2 spice).

Everyone should try to run a few things on it so that if anything
strange happens it can be noted. It should get home directories
before too much longer and maybe disc access will improve with the
new SCSI card (probably the limit is the discs though).
