代理文件：

#!/usr/bin/perl

use NetSNMP::OID(':all');
use NetSNMP::agent(':all');
use NetSNMP::ASN(':all');

sub myhandler {
    my  ($handler,$registration_info,$request_info,$requests) = @_;
    print "Handling request\n";
    for ($request = $requests; $request; $request = $request->next()) {
        #
        #  Work through the list of varbinds
        #
        my $oid = $request->getOID();
        print "Got request for oid $oi\n";
        if ($request_info->getMode() == MODE_GET) {
            if ($oid == new NetSNMP::OID($rootOID . ".3")) {
                $request->setValue(ASN_INTEGER,2);
            }
        }
    }
}

{
    $subagent = 0;

    print "Running new agent\n";
    my $rootOID = ".1.3.6.1.4.1.42134";
    my $regoid = new NetSNMP::OID($rootOID);
    if (!$agent) {
        $agent = new NetSNMP::agent('Name'=>'my_agent_name','AgentX' => 1);
        $subagent = 1;
        print "Starting subagent\n";
    }
    print "Registering agent\n";
    $agent->register("my_agent_name",$regoid,\&myhandler);
    print "Agent registered\n";

    if ($subagent) {
        $SIG{'INT'} = \&shut_it_down;
        $SIG{'QUIT'} = \&shut_it_down;
        $running = 1;

        while ($running) {
            $agent->agent_check_and_process(1);
        }

        $agent->shutdown();
    }
}

sub shut_it_down() {
    $running = 0;
    print "Shutting down agent\n";
}

当我运行代理时,我得到以下内容：

Running new agent
Starting subagent!
Registering agent with oid idb
Agent registered

所以我知道有很多工作要做.但是,当我运行以下命令时：

snmpget -v 1 -c mycommunity localhost:161 test2.0

我收到此错误消息：

Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: IDB-MIB::test2.0

我从snmptranslate知道mib文件设置正确.我甚至查看了snmpget的调试(使用-DALL)以确保正确加载和解析mib.

所以我的问题是：为什么我的子代理没有通过请求？

更新：

我被@EhevuTov告知我的MIB文件无效,但是smilint没有报告任何问题并且运行snmpget -v 2c -c mycommunity localhost：161 .1.3.6.1.4.1.42134.3.0报告了NAME对象(IDB-MIB :: test2.0)正确,但没有找到任何数据.

我在这个OID上获得IDB-MIB :: test2 =此代理上没有这样的对象,这让我认为我的代理没有正确注册,但是它没有丢失任何错误.

更新2：

我一直在调整代理代码.根据CPAN文档(http://metacpan.org/pod/NetSNMP::agent),如果成功,$agent->寄存器函数调用应该返回0.所以我检查了返回代码,得到了这个：

Agent registered. Result: NetSNMP::agent::netsnmp_handler_registration=SCALAR(0x201e688)

使用Data :: Dumper将其打印出来：

$VAR1 = bless( do{\(my $o = 34434624)},'NetSNMP::agent::netsnmp_handler_registration' );

我模糊地理解了什么是祝福,但即便如此,我也不知道这个结果应该是什么意思.所以我开始认为代理人在某种程度上是错误的.有谁知道如何调试这些代理？有什么地方我可以看看它是否正确加载到主snmpd？
