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.
