But when my system receive a NBNS request packet in port 137. The
Switch repond saying Destination Unreachable ( since the port is not
open ). But Henceforth when i do a SNMP get on my system My system gets

hanged. This happen exactly With the response to
SNMP get-Reuest as soon as the system send the SNMP response message
out through Socket using Sendto function my system gets hanged.
