I have written a small Novell network utility that determines a workstations
Internet (IP) address on the fly. This utility is to be used with the
Clarkson University modified NCSA Telnet and FTP software (CUTCP/CUTE).
The original idea was borrowed from Mark Bramwell's GET-IP, but enhanced
to take advantage of the Clarkson University's modification allowing the use of
environment variables as entries in CONFIG.TEL.
Using this utility, our network now maintains one copy of CONFIG.TEL, and
has FTP and TELNET batch files which are executed by the users.
In addition, this utility can be used in a multi-server environment so that
you do not receive conflicting IPs as results from using GET-IP.
This utility builds the "myip=..." string as can be found in a CONFIG.TEL file,
locks out a semaphore, sets the environment variable specified with the string,
and spawns the specified program. Upon exit of the program, the semaphore is
released.
The format of the command is as follows:
CU-IP baseIP beg end server var prog [args ...]
where
baseIP is the base range of your Internet Address
beg is the beginning of a range of valid IP addresses
end is the ending of the range of valid IP addresses
server is the server in which to lock the IP address on
var is the environment variable to use, eg. $CUTCP1
prog is the program to execute, eg. TN3270 or FTPBIN
args are the parameters to the program to execute
Given that our CUTCP software (and CUTCP-IP.EXE) is located at
Z:\APPS\TELNET
and our Novell File Server's name is OZ, we have the following batch files
for TELNET (tn3270) and FTP (ftpbin):
----------------------------- Begin TELNET.BAT ----------------------------
@echo off
cd z:\apps\telnet
z:cu-ip 129.130.75 220 235 oz $CUTCP1 z:tn3270.exe -h z:config.tel %1 %2
cd z:\
------------------------------- End TELNET.BAT ----------------------------
------------------------------- Begin FTP.BAT -----------------------------
@echo off
cd z:\apps\telnet
z:cu-ip 129.130.75 220 235 oz $CUTCP1 z:ftpbin.exe -h z:config.tel %1 %2
cd z:\
-------------------------------- End FTP.BAT ------------------------------
I place no restrictions on the use of this software. This software may not be
sold in any form and is freely distributable as long as this document
accompanies the software.
