如何使用pass\u persist with shell脚本创建可行走的snmpd扩展

snmp

如何使用pass\u persist with shell脚本创建可行走的snmpd扩展,snmp,net-snmp,mib,Snmp,Net Snmp,Mib,我在snmpd.conf文件中添加了以下两行： view all included .1.3.6.1.4.1.8072.9999.9999 pass_persist .1.3.6.1.4.1.8072.9999.9999 /root/kshtest 我创建了一个shell脚本（/root/kshtest），它接受一个文件OIDDEFS，其中包含每个OID的行、类型和值（用空格分隔）： 并在从命令行运行时提供以下交互： <- PING -> PONG <- get

我在snmpd.conf文件中添加了以下两行：

view all included .1.3.6.1.4.1.8072.9999.9999
pass_persist .1.3.6.1.4.1.8072.9999.9999 /root/kshtest
我创建了一个shell脚本（/root/kshtest），它接受一个文件OIDDEFS，其中包含每个OID的行、类型和值（用空格分隔）：

并在从命令行运行时提供以下交互：

<- PING 

-> PONG 

<- get 

<- .1.3.6.1.4.1.8072.9999.9999.1.1 

-> .1.3.6.1.4.1.8072.9999.9999.1.1 

-> integer 

-> 35

<- PING 

-> PONG 

<- getnext 

<- .1.3.6.1.4.1.8072.9999.9999.1.1 

-> .1.3.6.1.4.1.8072.9999.9999.1.2 

-> integer 

-> 21
并得到回应：

.1.3.6.1.4.1.8072.9999.9999.1.2 = INTEGER: 21
我可以成功地snmpget（netsnmp命令）我的MIB中的任何oid并获取它们的值，或者snmpgetnext任意oid并获取下一个oid和值。但是，我不能走路。当我

snmpwalk -On -v 2c -c public 127.0.0.1 .1.3.6.1.4.1.8072.9999.9999.1.1
我明白了

这和我在那个oid上从snmpget得到的回答是一样的

snmpwalk -d -v 2c -c public 127.0.0.1 .1.3.6.1.4.1.8072.9999.9999.1.1
给我：

它似乎是.1.3.6.1.4.1.8072.9999.9999.1.1旁边的snmpget，后面是引用.1.3.6.1.4.1.8072.9999.9999.1.2的snmpget，后面是引用.1.3.6.1.4.1.8072.9999.1.1的snmpgetresponse，后面是引用.1.3.6.1.4.1.8072.9999.1.1.1.1的snmpgetresponse

我更改了NET-SNMP-MIB.txt文件以添加MIB值，如下所示：

我希望这将给一个有经验的snmp'er足够的信息，看看我做错了什么。如果没有，请询问。谢谢。

Snmpwalk获取树中指定OID下的所有OID。由于您指定了.1.3.6.1.4.1.8072.9999.9999.1.1，因此它只获取该特定OID，因为该OID下没有其他OID。要遍历您定义的所有OID，请执行以下操作：

snmpwalk -On -v 2c -c public 127.0.0.1 .1.3.6.1.4.1.8072.9999.9999
@用户1693487问题是你的第三行

OIDDEFS=OIDDEFS

当作为服务/init.d运行时，需要完整的路径

OIDDEFS=/usr/bla/path/OIDDEFS
不管怎样，你的帖子帮助了我，因为我正面临着同样的问题！！因此，非常感谢下面的示例snmpd-f的行为与snmpd作为服务或从init.d运行时的行为不同。无论您如何处理OID，Walk/or Get都会失败。
