Hello Bruce,
back to OID length question...
command line works.
On Fedora-3 2.6.9-1.667 with net-snmp-5.1.2-11
it is the same behaviour as on solaris - after long
OID string short OID does not work.
Here is code example:
/****** main *******/
static char *oid2 = ".1.3.6.1.2.1.1.1.0";
static char *oid1 = ".1.3.6.1.4.1.9.3.6.7.0";
char *peer = "10.200.10.62";
int main(int argc, char **argv)
{
char *s;
snmp_init();
s = snmp_get(peer,oid1);
if (!s)
buffer_puts(buffer_1,"snmp_get failed\n");
else
buffer_puts(buffer_1,s);
buffer_puts(buffer_1,"\n\n");
s = snmp_get(peer,oid2);
if (!s)
buffer_puts(buffer_1,"snmp_get failed\n");
else
buffer_puts(buffer_1,s);
buffer_puts(buffer_1,"\n\n");
/* at this point it will not work */
s = snmp_get(peer,oid1);
if (!s)
buffer_puts(buffer_1,"snmp_get failed\n");
else
buffer_puts(buffer_1,s);
buffer_puts(buffer_1,"\n\n");
_exit(0);
}
/********* snmp_get *********/
#define COMMUNITY "testRW"
struct snmp_session session, *ss;
struct snmp_pdu *pdu, *response;
struct variable_list *vars;
oid serial_oid[MAX_OID_LEN];
size_t serial_len = MAX_OID_LEN;
static char rval[512];
char *snmp_get(char *peer, char *oidstr)
{
int rc = 0;
int status;
byte_zero(&session, sizeof session);
snmp_sess_init(&session);
session.version = SNMP_VERSION_2c;
session.community = COMMUNITY;
session.community_len = str_len(session.community);
session.peername = peer;
ss = snmp_open(&session);
if (!ss) {
strerr_warn2(FATAL, "unable open snmp session",0);
return 0;
}
pdu = snmp_pdu_create(SNMP_MSG_GET);
rc = 0;
status = snmp_synch_response(ss, pdu, &response);
if (status == STAT_SUCCESS) {
if (response->errstat == SNMP_ERR_NOERROR) {
byte_zero(rval,512);
vars=response->variables;
if (!vars)
strerr_warn2(FATAL, "unable get return
value",0);
else {
rc++;
snprint_value(rval, 512, vars->name,
vars->name_length, vars);
}
}
else
strerr_warn3(FATAL, "error in packet:
",snmp_errstring(response->errstat),0);
}
else if (status == STAT_TIMEOUT)
strerr_warn3(FATAL, "timeout: ",peer,0);
else
snmp_sess_perror("snmp_get",ss);
if (response) snmp_free_pdu(response);
snmp_close(ss);
return rc ? rval : (char *)rc;
}
/*****************/
i will appriciate any suggestion.
with kind regards,
