Windows: wrong result of module 'list of network interfaces'

[derDaywalker]

Hi,
the module 'List of network interfaces' produces wrong results under any windows system.

Ubuntu 16.04:

{
  "moduleName" : "List of network interfaces",
  "moduleDisplayName" : "List of network interfaces",
  "moduleVersion" : "0.1",
  "moduleClass" : "modules.SigarEnvironmentModules$SigarNetworkInterfaces",
  "extractionDate" : "xxx",
  "configurationHash" : "c6a4333de9553112399d6c3216a77d50",
  "results" : {
    "[Ljava.lang.String;" : [ "lo", "ens3" ]
  }
}

This is correct. But in Windows 10:

{
  "moduleName" : "List of network interfaces",
  "moduleDisplayName" : "List of network interfaces",
  "moduleVersion" : "0.1",
  "moduleClass" : "modules.SigarEnvironmentModules$SigarNetworkInterfaces",
  "extractionDate" : "xxx",
  "configurationHash" : "e6b5881ef42376510c7240050ee285f7",
  "results" : {
    "[Ljava.lang.String;" : [ "eth0", "eth1", "eth2", "eth3", "eth4", "lo0" ]
  }
}

This is obviously totally wrong as Windows don't use eth* naming scheme. Even worse the system has only one 'real' network interface (name: 'Ethernet') and the local loopback interface (name: 'Loopback Pseudo-Interface 1').

In WindowsXP it's wrong too:

{
  "moduleName" : "List of network interfaces",
  "moduleDisplayName" : "List of network interfaces",
  "moduleVersion" : "0.1",
  "moduleClass" : "modules.SigarEnvironmentModules$SigarNetworkInterfaces",
  "extractionDate" : "xxxx",
  "configurationHash" : "317285f5fc603e7628c15185cdaef818",
  "results" : {
    "[Ljava.lang.String;" : [ "eth0", "lo0" ]
  }
}

I forgot to mention, that I'm using PET version 1.2.1 from the download area (didn't compiled it).

Additionally the module 'network information' delivers wrong results too (Windows 10 result):

{
  "moduleName" : "Network information",
  "moduleDisplayName" : "Network information",
  "moduleVersion" : "0.1",
  "moduleClass" : "modules.SigarEnvironmentModules$SigarNetworkConfig",
  "extractionDate" : "xxxx",
  "configurationHash" : "f971ab552bac1c34335ad36d52cd3fc9",
  "results" : {
    "java.util.LinkedHashMap" : {
      "netInfo" : {
        "defaultGateway" : "10.0.2.2",
        "hostName" : "XXXXX",
        "domainName" : "",
        "primaryDns" : "10.0.2.3",
        "secondaryDns" : ""
      },
      "netConfig" : {
        "name" : "eth0",
        "hwaddr" : "52-xx-xx-xx-xx-56",
        "type" : "Ethernet",
        "description" : "Intel(R) PRO/1000 MT Network Connection-WFP Native MAC Layer LightWeight Filter-0000",
        "address" : "0.0.0.0",
        "destination" : "0.0.0.0",
        "broadcast" : "0.0.0.0",
        "netmask" : "0.0.0.0",
        "flags" : 65,
        "mtu" : 1500,
        "metric" : 0
      }
    }
  }
}

The netConfig results a partly wrong. The interface name is wrong and the addresses (all 0.0.0.0) are not correct.

Thanks, I will look into that for a fix, this is due to the Sigar library used for hardware configuration. It is probably OK to implement this as a command module - that can be configured even without intervening on PET code.
