Remote unix (RS/6000) servers with dial-ins

Remote unix (RS/6000) servers with dial-ins

Post by Nita Avala » Sun, 06 Dec 1992 13:06:10

Does any one out there have a following setup:

        Server:  RS/6000 servers at a remote site (e.g., California),
                 networked to an IBM mainframe (also at the same remote
                 site, possibly in an adjacent room and/or building) to
                 access large (GB and larger) datafiles.

        Users:   Dial-ins from another remote site (for example, Maine).
                 Users mostly dialing into the unix server to run large
                 compute-intensive jobs in the background (similar to batch
                 mode on the mainframe).  Most dial-up sessions would last
                 about 60-90 minutes over a 9600 baud line.

If you have/had a similar setup (or ever considered it), could you please
forward your experiences (good and bad), suggestions, do's and don'ts,
reliability, down time, performance, user satisfaction, and all other relevant
information.  Thanks in advance.


1. RS/6000 error msgs (Was: Re: RS/6000 survey - will post summary)

[LANG=En_US]  ksh: kjj: 0403-016 Cannot find or open the file.
[LANG=C]      ksh: kjj: cannot open

[LANG=En_US]  0506-764 ln: /tmp: Cannot use this command with a directory.
[LANG=C]      ln : </tmp> directory

 Canonicalizing all the error msgs by assigning them numbers and more
verbose explanations isn't such a bad idea, but it will hardly make
the system usable by secretaries. It does nothing to prevent an
accidental "rm *" or hide the details of the filesystem from the user.
Secretaries will run Motif and shrink-wrapped applications in
which case they will probably never [want to] use Unix shells. And they
shouldn't need to.
 The big gain here will be made by IBM SEs who will now be able to
look up customers' complaints by the error number.

    I haven't heard about IBM shipping *anything* on a Powerstation
yet. You can buy SunOS 4.1 *today* which is B2 certified.
And AT&T is advertising System V/MLS which is B1
certified -- I don't know if it's shipping yet.
    If security is important to you, you sure don't want to go with
a measly C2 rated system.
