Hi!
The obvious solution would be to stop using Windows and start using a
real OS, but I guess that's not the subject of the day... SCADA systems
I've bumped into have been using OPC for communications. Several vendors
have SNMP to OPC converters (Matrikon OPC SNMP server for instance) that
may be one way to go for you. A warning for the Matrikon product though.
Email me if you want to know the issues I've encountered with their product.
I think the -Lf does exactly what it's supposed to do:
"LOGGING OPTIONS
The mechanism and destination to use for logging of warning and
error messages can be controlled by passing various
parameters to the -L flag.
-Le Log messages to the standard error stream.
-Lf FILE
Log messages to the specified file."
You have no errors, and hence, no lines in the log file!
Try this:
snmpget -v 2c -c <community name withheld > <IP address withheld>
1.3.6.1.4.1.14817.3.3.2.20.1.5.2 >> "c:\Net SNMP\Output.txt"
