Notes for Running Netware over LAN Dista 8/29/94
Notes for running Netware over LAN Distance
-------------------------------------------
Netware Server
--------------
1. In order for a Netware server to support clients using packet
burst in a WAN environment, the netware server must have PBURST.EXE
or a later fix.
PBURST.EXE has packet burst files with a new packet burst algorithm for
WAN links to fix problems where 1) burst retries could saturate WAN links
due to low retry timeout values 2) workstations hang when duplicate packets
from a previous burst are received in the middle of the current burst.
PBURST.NLM is for use on NetWare 3.11 file servers. PBWANFIX.NLM (which
requires patchman) is for use on NetWare 3.12 and 4.01 file servers.
PBURST.NLM must have a date of at least 4/5/94 and PBWANFIX.NLM
must have a date of at least 4/19/94.
2. In a token ring environment, make sure that ROUTE.NLM is loaded on the
Netware server. Since the LAN Distance connection server is a token
ring bridge, source level routing information must be in frames in
order to be delivered to the WAN by the connection server.
OS/2 Netware Requester
----------------------
The following recommendations are for running OS/2 Netware Requester.
Note that a few of the steps only apply to a token ring environment.
1. To improve performance, copy frequently used netware utilities to
the Netware requester. For example: LOGON.EXE, LOGOUT.EXE,
MAP.EXE and SLIST.EXE.
2. The following is a sample NET.CFG. Use this configuration
when first attempting to use the netware requester
over LAN Distance. Do not use the normal buffer size
of 4202 for a token ring environment, use 1514.
NetWare Requester
Default Login Drive L
cache buffers 30
directory services off
Link Support
Buffers xx 1514
3. For a token ring environment, LAN Distance requires that
all frames have source routing information. This means that
ROUTE.NLM must be loaded on the netware server and ROUTE.SYS
must be loaded for the netware requester.
4. The Netware requester must have a fix for NWREQ.SYS. The
fix must be 7/21/94 or later. This fix can only be installed
on the OS/2 Netware Requester. The APAR for this fix is IC07834.
The Netware requester for OS/2 has a fixed timeout value
for resending frames when there has been no response from
the server. Over a slow link this can cause frames to be
retransmitted several times causing slow performance and
REQ1040 and REQ1039 error messages from NETWARE.
NWREQ.EXE contains the 7/21/94 NWREQ.SYS fix from novell which increases
the timeout value. There is a side effect to this fix. When the
LAN Distance connection is dropped, it will take several minutes
for Netware to destroy the default drive due to the longer timeout
value. You may notice this when you are trying to shutdown OS/2.
5. Make sure the NW requester for OS/2 is version 2.1.
Otherwise NWDAEMON must be executed after the LAN Distance
connection has been established by issuing DETACH C:\NETWARE\NWDAEMON.
Netware Client for DOS
----------------------
1. When using packet burst for the DOS netware client, the latest VLM.EXE
is required. VLM.EXE must be at least dated 5/31/94. VLM11.EXE
contains the 5/31/94 fix. The APAR for this fix is IC08000.
2. To improve performance, copy frequently used netware utilities to
the Netware requester. For example: LOGON.EXE, LOGOUT.EXE,
MAP.EXE and SLIST.EXE.
3. For a token ring environment, LAN Distance requires that
all frames have source routing information. This means that
ROUTE.NLM must be loaded on the netware server and ROUTE.COM
must be loaded for the netware requester.
4. Make sure that DOSUP9 and WINUP9 (or later) fixes have
been applied for the Netware client.
5. In order to enable LAN Distance for Netware during LAN Distance
installation or through settings, LSL.COM and VLM.EXE must be
in the netware directory. LAN Distance requires the use of
VLM.EXE.
