SNeO

SNeO is an SNMP Network Simulator. SneO runs SNMP agents that loads MIB instances from human-readable text files (Text MIBs), ICMP nodes, and a network between the agents and nodes.

Download

• SNeO 1.2.3

Features

SNeO has the following features:

• Multi-platform. (e.g. Windows, CentOS, Solaris (SPARC, x86), HP-UX (IPF), etc.)
• SNMP agent simulation (powered by SNMP4J-Agent)
  • SNMPv1/v2c/v3
  • IPv4/v6
  • GET, GETNEXT, SET, and GETBULK
  • Dynamic sysUpTime
  • Sending coldStart trap
  • SNMP community string indexing
  • JMX
    • to get agent information
    • to stop/start agents
    • to change the log level
    • to get/set MIB instances
    • to reload Text MIBs
    • to get SNMP access statistics
• Network simulation (powered by Pcap4J)
  • IPv4/v6
  • ICMPv4/v6
  • Node with multi IP address
  • VLAN
  • Link aggregation
• Sending SNMP request (powered by SNMP4J)
  • SNMPv1/v2c/v3
  • GET, GETNEXT, SET, and GETBULK
  • Walking an SNMP agent and generate a Text MIB

Build

Git, Maven 3, and JDK 1.8 are required to be properly installed.

$ git clone https://github.com/kaitoy/sneo.git
$ cd sneo
$ mvn install

How to Use

Preparation

Maven 3 and JDK 1.8 are required to be properly installed.

The following command downloads dependencies and copies the SNeO core artifact from the target directory.

$ cd sneo-core/bin
$ ./prepare.sh

Generating Text MIBs

JRE 1.8 is required to be properly installed.

SNeO snmpwalks on a device and generate a Text MIB by the following command.

$ cd sneo-core/bin
$ ./walk.sh {community string} {target hostname} . 1> {Text MIB}

Alternatively, you can use snmpwalk command of net-snmp-utils.

$ snmpwalk -M /dev/null -On -Oe -OU -c {community string} -v 2c {target hostname} . 1> {Text MIB}

Simulating an SNMP agent

JRE 1.8 is required to be properly installed.

$ cd sneo-core/bin
$ ./runAgent.sh {Text MIB} {agent IP address} {community string}

By the above command, SNeO starts to listen at the specified IP address and port 161. It's needed that the IP address is added to an interface before starting simulation.

Simulating multiple SNMP agents at once

JRE 1.8 is required to be properly installed.

Simulating a network node

JRE 1.8, a pcap library (e.g. libpcap, WinPcap, and Npcap) are required to be properly installed.

Giane

Giane is the Web GUI for SNeO. Download giane-jetty.war from here and execute the following command with JDK 7:

java -jar giane-jetty.war --httpPort 8080 --jmx.httpPort 8082 --jmx.rmiPort 1099

After a while, you'll see a message ** Hit Enter key to stop Giane **, which means Giane has been started. Then, open a Web browser, access to http://localhost:8080/giane/ and play with Giane.
