hello
i want to reset password o my device through snmp client (i.e.MIB
browser).Agent will receive the password string and send it to UART.
MIB contains-
PasswordReset OBJECT-TYPE
SYNTAX DisplayString
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"Device password reset. Password length is Max 8 characters"
::= { commonSystemParams 10}
following is code snipt for password handle-
char pwd_str[]="1234";
int handle_PasswordReset(netsnmp_mib_handler *handler,
netsnmp_handler_registration *reginfo,
netsnmp_agent_request_info *reqinfo,
netsnmp_request_info *requests)
{
int ret; char str_pwd[4]="";
/* We are never called for a GETNEXT if it's registered as a
"instance", as it's "magically" handled for us. */
/* a instance handler also only hands us one request at a time, so
we don't need to loop over a list of requests; we'll only get one. */
switch(reqinfo->mode) {
case MODE_GET:
snmp_set_var_typed_value(requests->requestvb, ASN__OCTET_STR,
/* XXX: a pointer to the scalar's data
*/
(u_char*)&pwd_str,
/* XXX: the length of the data in
bytes */
sizeof(pwd));
break;
.
.
.
.
case MODE_SET_COMMIT:
//here is the problem to store password string
str_ pwd=*(requests->requestvb->val.string);/* XXX: delete
temporary storage */
write(fd,str_pwd,4); //write to serial port
usleep(100000);
/* XXX: delete temporary storage */
if (/* XXX: error? */0) {
/* try _really_really_ hard to never get to this point */
netsnmp_set_request_error(reqinfo, requests,
.
.
.
.
return SNMP_ERR_NOERROR;
}
I am able to get the password string but not able to set.
Any suggestion
Thanks in advance.
