Web GUI for snmpsim - http://snmpsim.sourceforge.net

This provides a Web interface for the snmpsimd.py SNMP Simulator program written by written by Ilya Etingof [email protected] The snmpsim program acts like a set of SNMP-speaking devices, responding to SNMP queries sent to it. snmpsim uses the community string of the SNMP query to select which set of SNMP responses to send.

websnmpsim.py is a single file added to the base snmpsim distribution that provides the Web GUI. When it's installed, websnmpsim.py does several things:

1. It launches snmpsimd.py, so that the simulator itself runs normally.
2. It provides a small web-based GUI on port 8880 to list all the simulated devices and the associated SNMP community strings.
3. It allows you to import additional SNMP data files, so that you can simulate additional devices.

Read the "README.txt" file for much more information about the snmpsim project. This repository is based on the snmpsim 0.2.0 release of 12 March 2013.

To use the websnmpsim.py program:

• Retrieve the repository from github. It's at: https://github.com/richb-hanover/websnmpsim or use git clone https://github.com/richb-hanover/websnmpsim.git
• cd to the websnmpsim folder and run the setup sudo python setup.py install
• cd to the snmpsim/scripts directory and run websnmpsim with python websnmpsim.py
• Connect to the web GUI at: http://localhost:8880. snmpsimd.py will be listening for SNMP queries at the address/port indicated in the web GUI. You also see a list of all the simulated devices, and the SNMP community string to use.
• To upload a .snmprec file, click Browse to select a file, then click Add. It will be placed in the current directory.
• Ctl-C in the terminal window to abort both the Web GUI and snmpsimd.py

Prerequisites: You may need to install the following packages/modules before snmpsimd.py and websnmpsim.py will run:

• easy_install (install this first to get the others)
• twisted
• pyasn1
• pysnmp

WARNING: Although this program seems to work, it is a two-weekend hack. I wanted to learn a little about Twisted, so this program was a decent vehicle for that learning. I make no claim to the value of this as a starting point for further work.

Since snmpsimd.py is already based on Python's asyncore, that module may be a better base for long-term development. In fact, the are a lot of lines of communication between the Web GUI and snmpsimd.py which argues that they should be combined.

Please let me know if this is useful for you, or contribute your changes back to the snmpsim project. http://snmpsim.sourceforge.net
