如何更改默认的MIB搜索路径？
如何更改默认的MIB搜索路径？
提问于 2012-11-08 07:19:19
下面的代码用于解析名为mibp的文件夹中的mibp。
#include <net-snmp/net-snmp-config.h>
#include <net-snmp/net-snmp-includes.h>
#include <string.h>
#include<stdlib.h>
int main(int argc, char ** argv)
{
FILE *fp=NULL;
fp=fopen("/root/mib2.txt","w");
if (fp == NULL )
{
printf("error");;
exit(2);
}
netsnmp_init_mib();
add_mibdir("/home/pradipta/snmp/share/snmp/mibp");
//netsnmp_set_mib_directory( "/home/pradipta/snmp/share/snmp/mibp" );
struct tree *node;
//node=read_all_mibs();
node=read_mib("/home/pradipta/snmp/share/snmp/mibp/EtherLike-MIB.txt");
print_subtree(fp,node,0);
}当我运行这个程序时，我会犯以下错误

Undefined identifier: transmission near line 118 of /home/pradipta/snmp/share/snmp/mibp/EtherLike-MIB.txt我已经将文件夹名mibs更改为mibp，并将其添加到代码中，以测试mib搜索路径的更改，或者not.it给了我这个错误的原因。
netsnmp_init_mib();的用途是什么？
也告诉我
- 我将使用哪个函数来更改MIB搜索目录。
- 函数
netsnmp_set_mib_directory()的用途是什么？ - 如果我想添加一个MIB，那么是否可以只给出MIB的路径，或者必须将其包含在以前所有MIB都存在的路径中，因为我在这样做时会出现错误。
- 另外，
read_all_mibs() and read_mib()之间的区别是什么？
请告诉我一些想法。

它试图包括你的MIB所依赖的其他MIB。很可能是找到了你的具体信息。只需在默认MIB所在的地方添加另一个add_mibdir()即可。
add_mibdir("/usr/local/where/my/default/RFC/mibs/are");
