2017-02-14 Thread christopher.wu

I downloaded the code for 5.7.2.1 again because I wanted to insert trace statements so that I could tell you what the values were for the variables listed in #2 from your message. I ran configure with these options: ./configure --without-nl --with-transports=UDP TCP Unix UDPIPv6 TCPIPv6

scenario where IPv6 traps are being sent via the wrong default port (161)

2014-05-12 Thread christopher.wu
I looked in the bug database and didn't see this listed. I've found a scenario where snmptrap will default to port 161 for a IPv6 trap instead of port 162. In sending a simple trap on the command line I realized that it was stripping off the end of my IPv6 addr and using it as a port.

Informs stop retrying when the network goes down

I have found that when I pull the WAN Ethernet cable from the device I'm running snmptrap on my inform retries will stop immediately. If I pull the cable before I run snmptrap it exits immediately when I launch it. If I wait until it has retried a few times and pull the cable it exits before
