copied!<p>I am currently trying to get the basic example code working for the node.js library node-snmpjs in the c9.io development environment.</p> <p>The example code is here: </p> <p><a href="https://github.com/wesolows/node-snmpjs" rel="nofollow">https://github.com/wesolows/node-snmpjs</a> or </p> <p><a href="https://npmjs.org/package/snmpjs" rel="nofollow">https://npmjs.org/package/snmpjs</a></p> <pre><code>var os = require('os'); var snmp = require('snmpjs'); var logger = require('bunyan'); var log = new logger({ name: 'snmpd', level: 'info' }); var agent = snmp.createAgent({ log: log }); agent.request({ oid: '.1.3.6.1.2.1.1.5', handler: function (prq) { console.log("Request received"); var nodename = os.hostname(); var val = snmp.data.createData({ type: 'OctetString', value: nodename }); snmp.provider.readOnlyScalar(prq, val); } }); agent.bind({ family: 'udp4', port: 161 }); </code></pre> <p>I've tried changing the bind port to: parseInt(process.env.PORT)</p> <p>When I try to execute an snmpget against the address and port that c9 spits out on run, it fails. I've also tried :8080. 8080 is what c9's console output always says is is mapped to process.env.PORT. I've also tried port 80 in the snmpget.</p> <p>As a fallback, I've also tried making a basic telnet, socket connection using c9 and can't get it to work... It seems like the root problem may be that I don't know what IP and port is being used.</p> <p>------------------------- EDIT ------------------------</p> <p>I've tried the following variations on the agent.bind line:</p> <pre><code>agent.bind({ family: 'udp4', port: parseInt(process.env.PORT), addr: process.env.IP}); </code></pre> <p>and</p> <pre><code>agent.bind({ family: 'udp4', port: 17000, addr: process.env.IP}); </code></pre> <p>Output:</p> <pre><code>Your code is running at 'http://node-dev1.thaspius.c9.io'.
