Hi, everyone
I am a snmp newbie developer, and want to write some new OIDs.
And generate sample code from mib2c MY-DEFINE-MIB file.
But when i develop this part, i meet a big problem:
when set string, requests->requestvb->val.string always remain some old
data, i don't know how to empty it.
Ex:
snmpset -v 1 -c XXX localhost [A OID] s "ABCDEFGHIJ"
snmpset -v 1 -c XXX localhost [B OID] s "1234567"
snmpget -v 1 -c XXX localhost [B OID]
==> "1234567HIJ"
So i want to ask how to solve this problem?
Thanks.
This is my code:
==================================================
...
static char A[100];
static char B[30];
...
void
init_XXX(void)
{
const oid A_oid[] = { ... };
const oid B_oid[] = { ... };
...
}
int
handle_AOID(netsnmp_mib_handler *handler,
netsnmp_handler_registration *reginfo,
netsnmp_agent_request_info *reqinfo,
netsnmp_request_info *requests)
{
...
switch (reqinfo->mode) {
case MODE_GET:
snmp_set_var_typed_value(requests->requestvb,
ASN_OCTET_STR, A, sizeof(A));
break;
...
case MODE_SET_ACTION:
strncpy(A, requests->requestvb->val.string,
sizeof(A));
A[sizeof(A)-1]='\0';
break;
...
}
...
}
int
handle_BOID(netsnmp_mib_handler *handler,
netsnmp_handler_registration *reginfo,
netsnmp_agent_request_info *reqinfo,
netsnmp_request_info *requests)
{
...
switch (reqinfo->mode) {
case MODE_GET:
snmp_set_var_typed_value(requests->requestvb,
ASN_OCTET_STR, B, sizeof(B));
break;
...
case MODE_SET_ACTION:
strncpy(B, requests->requestvb->val.string,
sizeof(B));
B[sizeof(B)-1]='\0';
break;
...
}
...
}
===============================================
And other part codes, i almost not modified them, continue to use from
mib2c auto-generate.
