The decision to discontinue support for these protocols was made for
a variety of reasons. These are discussed in detail in the article
"AppleTalk and IPX: Your days are numbered!"
published
in the Spring 2001 issue of Berkeley Computing and Communications.
-
AppleTalk zones will no longer appear in the Chooser. You will not
be able to browse AppleTalk file sharing and print services on
remote subnets. Connecting to computers and printers in remote
subnets will require TCP/IP. Detailed instructions for connecting
to TCP/IP resources are available in a separate
How-To document.
-
Due to the broadcast traffic generated by and associated with
these protocols, network performance is adversely affected at
several levels, including the local subnet. Numerous departments
which never needed or no longer require AppleTalk or IPX support
for their printers or servers have requested that we discontinue
routing these protocols to their subnets prior to the September
30th cutoff so that they may avoid superfluous broadcast traffic
as soon as possible. Local (IP based) traffic can move more
quickly and freely if it need not compete with AppleTalk and IPX
broadcasts for valuable bandwith and network resources.
-
Changing the configuration of numerous routing devices across campus
is a daunting task, and will not occur all at once.
IPX and AppleTalk will no longer be supported after
12:01am on Tuesday, 01 October 2002, and is subject to being turned off at
any time after that. We will attempt to notify departmental administrators
prior to the making changes that will affect their networks.
(In some cases, where networks span multiple
departments, we will attempt to notify administrators throughout the affected
building). In addition, we will make
announcements on the
Micronet and
MAGNet
mailing lists, as well as the
ucb-net-announce@UCLink list, the latter of which is
reflected to the USENET group ucb.net.announce.
Keep an eye on these lists for more information.

For Novell, version 4.0 is required, but 5.x is recommended.
AppleShare Server versions 5 and later support IP.
Macintosh clients should be running MacOS 8.6 or later
-
With MacOS 7.6.1 - 8.5.1, it's still possible to connect to IP
resources, but you will have to download newer drivers and client
software. Please see the How-To document
for more details.

Check out the step-by-step procedures for
connecting to an LPR printer, and for
connecting to a server via TCP/IP.
-
Check your user manual or contact the printer manufacturer to verify whether or
not your printer is capable of IP networking. If it is not, you may consider
directly attaching it to an existing IP server and allow that machine to share
the printer. A simpler alternative may be just to replace the aging printer
with one that is IP capable.
-
If your departmental server(s) and client machines are all on a
single subnet, then AppleTalk/IPX routing is not necessary
for the services on your machines.
AppleTalk/IPX functionality will continue to work within any given subnet even
after CNS disables the forwarding of these protocols across
the campus network. However, even in this case, configuring your clients
and server to use IP may increase your local performance somewhat
as your subnet will no longer be subjected to as much broadcast
traffic.
-
Your servers and printers were formally members of an AppleTalk
zone. These zones are defined and propogated by campus routers.
With the abatement, these zones no longer exist, and thus,
your former printer and server connections, which were made with
reference to AppleTalk zones, are no longer valid. While the AppleTalk
zones will no longer appear in the Chooser, your local printers
and servers should. Simply reselect the resources you desire.
-
Such migrations may not be entirely painless. However, it's
important to note that versions of Netware and AppleShare
file-sharing software which cannot use IP at all are extremely
old. Chances are, most departments are already running software
that can use IP as its network protocol. In addition, there are
numerous vendor resources that can assist with migration.
Finally, IST and other organizations provide some resources that
may help with the migration. Subscription services, like
Department On-Site Computing
Support
(DOCS, http://docs.berkeley.edu) and Letters & Science Computing
Resources (LSCR, http:ls.berkeley.edu/lscr/) can assist their
customers with migration issues. IST's Workstation Software Support
Group (WSSG, http://wssg.berkeley.edu/) may also be able to
provide help and technical information.

When attempting to print to the late model HP LaserJet
series printers, (4000 and 4100, among others)
some users report that printing using the Citrix client fails
silently, although they can print from other applications
using the LPR printer setup.
Download the latest Citrix client and follow the installation and
configuration instructions graciously provided by
Departmental
On-site Computer Support.
