Original-subject: Annuncing TFTP and XDM server for Xterminals.
Reposted-by: emv@msen.com (Edward Vielmetti, MSEN)
NCD (and probably others) Xterminals usually boot from VMS using MOP and
access files using DECnet's FAL protocol. The latter is sometimes slow as
a new process must be created sometimes. A more severe problem is that it
works only on terminals which have DECnet license, and most companies sale
it separately; not everyone buys this option...
To solve the two problems it is possible to use TFTP to load the terminals
and use XDM to start the login session. There are some severe problems with
XDM which can be overcomed to some extent.
A few pograms which do these functions using MultiNet (tested on NCD terminals
but will probably work with little changes on Visual and others) can be
retreived using anonymous FTP from VMS.HUJI.AC.IL at the [.LOCAL] directory
under the name FTP_XDM.BCK_Z; the saveset is a compressed one which can be
decoded using the LZDCM.EXE program at the [.AAALOOKHERE] directory.
Note: The main difference between the standard TFTP server and this one is
that the latter does not allow writing files, will serve only listed machines,
and will allow access to only two directory trees (the standard VMS fonts and
a defined directory for configuration and terminal image files).
Good luck, __Yehavi:
