	tcp41b.exe;  439880 bytes;  Date/Time:  02-09-96/5:19p

NOVELL PRODUCT CLASS:

     Internetworking

     NetWare OS

NOVELL PRODUCT and VERSION:

     NetWare MultiProtocol Router 3.0

     NetWare 4.1



ABSTRACT:

TCP41B.EXE contains two versions of TCPIP:

- TCPIP.NLM 3.0h, which is to be applied ONLY to NetWare 4.10

servers.

- TCPIP.NLM 3.0f, which is to be applied ONLY to NetWare 3.12

servers running MultiProtocol 3.

If you fit either of those categories, and use TCP/IP, TCP41B.EXE

is a recommended download.   

If you do not fit the categories, do NOT download this patch!  

In the required environments, TCP41B.EXE resolves various issues

with TCP/IP as well as bootp forwarding.

SYMPTOM

Symptoms Corrected by TCP/IP 3.h only.

--------------------------------------

1. Failure of OSPF

unnumbered WAN links to recover when physically switching ports.



2. Low Cache Buffers and lost ECBs.



3. Abend when attempting to

bind to more than 32 TCP/IP connections.



4. Abend when bootpfwd

received packets with mac-addresses greater than 10 bytes.



Symptoms Corrected by both TCP/IP 3.f and 3.h.

---------------------------------------------

5. An abend when

TCP/IP header compression was enabled on media that does not

support header compression.  NOTE: TCP/IP header compression is

supported only on PPP.



6. TCP/IP directed broadcasts forwarded

in only one direction.



7. Intermittent abends, when CALLMGR was

used to bring up an on-demand IP call.



8. A page fault if a TCP

or UDP stream was aborted, while data was in transmission.





New

Feature provided by both TCP/IP 3.f and 3.h

-----------------------------------------------

The maximum

number of "TCP Connections Requests" held in the Socket Queue

to

be processed, has been increased from 5 to 32.  In addition, if

the Socket Queue contains 32 "TCP Connections Requests"

additional Requests will not be rejected.  Instead, the remote

node will be required to resend the connection request.  (By that

time, some of the earlier requests in the queue will be

processed, and the newly resent request will be accepted.)  This

will benefit TCP applications running heavy traffic.

SOLUTION

Apply the files found in TCP41B.EXE according to the instructions

in this document.

Make sure you use the files from the correct directory.

Installation Instructions:

1. Do NOT install any part of TCP41B.EXE over TCPIP 2.x. 



2. Do NOT install any part TCP41B on a system which has NetWare

MultiProtocol Router version 2.x (or earlier).



3. Make a backup copy of the "old" BOOTPFWD.NLM, TCPCFG.NLM, and

TCPIP.NLM.



4A. ONLY, if you are applying the patch to a NetWare 4.1 server

copy the files in the "4" directory of TCP41B into SYS:\SYSTEM.



4B. ONLY, if you are applying the patch to a NetWare 3.12 server

running MultiProtocol Router 3, copy the files in the "3"

directory of TCP41B into SYS:\SYSTEM.



4C. For all other systems, instead, apply TCP31A.EXE.
