Dear:
I have a problem about snmpset,when I set only one variable,all the
values of variables are changed .
I want to change the value of only one variable,what can I do to
solve the problem?
For example,when I use:
"snmpste -v2c -c private localhost upFlow.0 i 3"
to set the value of upFlow. It's OK.
But the values of other variables are changed to 3:
"snmpget -v2c -c private localhost downFlow.0 ",
it returns:
"SGCC-MIB::downFlow.0 = INTRGER 3"
What should I do?
Here is parts of my program,"example_int"is a global variable:
case DOWNSNDPACK:
long_ret = example_int;
*write_method = write_exampleint;
return (u_char *) & long_ret;
case DOWNRCVPACK:
long_ret = example_int;
*write_method = write_exampleint;
return (u_char *) & long_ret;
case DOWNFLOW:
long_ret = example_int;
*write_method = write_exampleint;
return (u_char *) & long_ret;
case CPURATE:
strcpy(string, example_str);
*var_len = strlen(string);
*write_method = write_examplestr;
return (u_char *) string;
int write_exampleint(int action,
u_char * var_val,
u_char var_val_type,
size_t var_val_len,
u_char * statP, oid * name, size_t name_len)
{
#define MAX_EXAMPLE_INT 100
static long intval;
static long old_intval;
switch (action) {
case RESERVE1:
if (var_val_type != ASN_INTEGER) {
DEBUGMSGTL(("example", "%x not integer type",
var_val_type));
return SNMP_ERR_WRONGTYPE;
}
if (var_val_len > sizeof(long)) {
DEBUGMSGTL(("example", "wrong length %x", var_val_len));
return SNMP_ERR_WRONGLENGTH;
}
intval = *((long *) var_val);
if (intval > MAX_EXAMPLE_INT) {
DEBUGMSGTL(("example", "wrong value %x", intval));
return SNMP_ERR_WRONGVALUE;
}
break;
case RESERVE2:
break;
case FREE:
break;
case ACTION:
old_intval = example_int;
example_int = intval;
break;
case UNDO:
example_int = old_intval;
break;
case COMMIT:
break;
}
return SNMP_ERR_NOERROR;
}
