I'm trying to figure out why I have a null community in my agent when using 5.2.rc1
but the same code works OK with 5.1.1. I've got:
struct snmp_session session;
init_snmp("snmpapp");
snmp_sess_init( &session );
session.peername = "localhost";
session.retries = 1;
session.version = SNMP_VERSION_2c;
session.community = "config";
session.community_len = strlen(session.community);
snmp_log(LOG_INFO, "session.community:<<%s>>, community_len:%d\n",
session.community, session.community_len);
ss = snmp_open(&session);
snmp_log(LOG_INFO, "ss->community:<<%s>>, community_len:%d\n",
ss->community, ss->community_len);
which shows session.community to be "config" and ss->community to be null. I edited
snmp_open() to start:
struct session_list *slp;
snmp_log(LOG_INFO,
"%d:session->community=%s\n",
__LINE__, session->community);
and find that session->community is NULL *on* *entry* to snmp_open(). Then I noticed
that I'm passing snmp_open() a struct snmp_session* but it's defined as:
netsnmp_session *
snmp_open(netsnmp_session *session)
{
....
Which leaves me wondering if snmp_session and netsnmp_session used to be compatible
and aren't any more. Any other explanation that the community pointer on the
structure gets trashed by invoking snmp_open()?
