"SLAC LocalTalk/PhoneNet Phase Out" by Ken Martell on the planned
migration of Macintosh LocalTalk/PhoneNet connections to direct ethernet
connections. Users with a continued need to connect to LocalTalk (e.g. visitors
with a Powerbook with no Ethernet connection) are recommended to use a
Farallon Etherwave LocalTalk to Ethernet Adapter (PN840) and for printers
PN842. For details such as price, availability of a loan etc., on the
Etherwave adapters, contact Fred Hooker.
- We do
not intend to make any further upgrades to the QuickMail software.
We will continue to provide central Quickmail support until the end of calendar
1996, or until the current software breaks,
whichever comes first.
This is due
to: the high cost of support for Quickmail in the SLAC environment; and the
availability of Eudora as an alternative supported service.
For more details contact Ken Martell.
- SLAC dropped its BITNET connection at the end of June 1996.
You may be able to locate the
last known Internet address for an extinct BITNET node by looking at

Phase IV connectivity is being phased out in the HEP/Esnet community.
Thus DECnet Phase IV services are expected to degrade over time,
DECnet Connectivity Possibly Breaking Down In April 1996!
SLAC will follow the
ESnet-DECnet recommendations on installation of DECnet/OSI and use of
DECnet/IP which may be found at the
Working Group Public Home Page. The contact person at SLAC is
"Phase-Out of the Micom Switch" by Ken Martell, Mar-1994,
an announcement of the
plan to migrate, by the end of 1997, from Micom terminal connections
to personal computers connected to the Ethernet.

current version of Xremote at SLAC is insecure and
the vendor of the terminal
server which we use for the Xremote gateway does not support upgrades.
The service is receiving little use; the people resources with skills
to support the service has been dramtically reduced recently; and
other emerging services (e.g. ISDN) are more effective.
We are therefore freezing Xremote support. There will be no additional
ports or new releases of the software. If it should stop working with a
new version of some other SLAC supported software (e.g. a new version of X11)
no effort will be expended fixing it. To resolve the security issue we
will be providing some required safeguards that may make use of Xremote
less transparent. Newer versions of the NCD Xterminals (with code version 3.2.1
or later) do have SLIP and PPP built built in and so can access SLAC via the
campus SLIP service
Netcom or another
Internet Service Provider with SLIP/PPP support.
For more details contact
Don Pelton. A corollary of this reduction
in support is that we no longer recommend NCD
Xterminals for home use with
- SLACnet, the
VM to VMS file transfer software developed at SLAC in the mid-1980s, still
works for VAX/VMS V6.2 and earlier versions.
We have no intention of supporting it
it on Alpha/VMS and upgrading it to VAX/VMS V7.0 will be done only if requires
No support for SLACnet will be provided after March 1997,
when VM logon is discontinued.

if you need more details on this.
