SUMMARY
================================================================
This patch contains files that update the IPTUNNEL.LAN in NetWare 3.11 Rev
A. The version of IPTUNNEL.LAN to be updated is v1.00, dated February 8,
1991. IPTUNNEL.LAN will be updated to v1.02 dated October 19, 1991. The
original file has a byte count of 5912. The updated file has a byte count
of 6061.
FIXES
-----------------------------------------------------------------
IPTUNNEL.LAN v1.02 fixes a bug that caused the server to ABEND when IP
packets are fragmented within the IP tunnel.
INSTALLATION
----------------------------------------------------------------
Installation of the patch is performed at a workstation with about 1mb of
free disk space and connection to the NetWare server containing the
IPTUNNEL.LAN to be updated. The procedure is:
- create a temporary area on the workstation
- load the patch files and the IPTUNNEL.LAN in the temporary area
- execute the patch
- transfer the updated IPTUNNEL.LAN back to the server
Though the procedure updates the IPTUNNEL.LAN from the server, IPTUNNEL.LAN
from the SYSTEM-3 NetWare 3.11 diskette can be used and later loaded on the
server. IPTUNNEL.LAN can be found on the SYSTEM-3 diskette in the directory
\TCPIP\SYSTEM.
1) On the workstation, create a temporary directory to contain the patch
files and a sub directory to contain IPTUNNEL.LAN.
MKDIR \TEMP
CD \TEMP
MKDIR IPTEMP
2) Load the patch files to the directory TEMP. (This procedure assumes the
patch files are on diskette. Drive A is used for the location of the patch
files.)
COPY A:*.*
3) Login or attach to the NetWare server as supervisor and map a drive to
SYS:SYSTEM. (Drive X: is used for demonstration purposes.)
ATTACH servername\SUPERVISOR
PASSWORD:password
MAP X:=servername\SYS:SYSTEM
4) Remove the READ ONLY attribute from IPTUNNEL.LAN and create a backup
copy.
X:
FLAG IPTUNNEL.LAN N
NCOPY IPTUNNEL.LAN IPTUNNEL.SAV
5) Copy IPTUNNEL.LAN to the temporary directory.
NCOPY X:IPTUNNEL.LAN C:\TEMP\IPTEMP\IPTUNNEL.LAN
6). Set the current directory to the temporary directory containing the
Patch files and execute the patch.
C:
CD \TEMP
PATCH IPT102
7) Check the date and size of the file IPTUNNEL.LAN to ensure the file is
updated.
DIR IPTEMP\IPTUNNEL.LAN
The file date should now be 10-19-91 and the byte count should be 6061.
8) Copy IPTUNNEL.LAN back to SYS:SYSTEM
NCOPY C:\TEMP\IPTEMP\IPTUNNEL.LAN X:IPTUNNEL.LAN
9) Set the current drive to the Network drive and replace the READ ONLY
attribute to IPTUNNEL.LAN.
X:
FLAG IPTUNNEL.LAN ROS
10) Logout of the server and delete the temporary directories.
LOGOUT servername
C:
CD \TEMP\IPTEMP
DEL *.*
CD ..
DEL *.*
RMDIR IPTEMP
CD ..
RMDIR TEMP
11) If the IPTUNNEL is currently loaded, go to the server console, unload
the module and reload the IPTUNNEL.LAN.
:UNLOAD IPTUNNEL.LAN
:LOAD IPTUNNEL.LAN
The update is now complete. Refer to the NetWare TCP/IP Supervisor's Guide
for usage of IPTUNNEL.
