(2)Set SNMP agent trap message to version 1, destination IP as SNMP manger's IP. (3)Do some operation to generate trap message, such as make one port of SNMP agent up and down. But SNMP manger can't accept trap message. I have capured the packet by Ethereal software, and check the SNMP trap packet, found that the UDP checksum is incorrect. I think that the function fast_csum()(nf_nat_snmp_basic.c) have some problem. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. --
