Hi Dan Pattison,
In my machine i don't have /etc/hostname .But i am reading hostname from my
API and updating it in sysName before calling the
netsnmp_create_update_handler_registration
 But i am seeing that when i do snmpwalk it's directly calling
netsnmp_create_update_handler_registration
API. Suspecting that due to this one its not updating the sysName. Same
behavior i am seeing for sysLocation and sysContact also.

Thanks,

Venkateswarlu.K
