That is the approach I am working on now. But it is not the best one because my requirement was to provide a library with a function that performs this turn over. So in this case I will have to tell my customer to re-start his process each time the turn over is done. However, thank you for your re

Hello,   I took a look at the snmp code and I found out that in the function static void _init_snmp(void) there is a static variable called have_done_init that prevents snmp from doing more than one initialization. The same happens in the function void init_snmp(const char *type). I think

I tried both versions in the computer where the client is but the program is still unsuccessful. Do you think that the snmp version 5.1.3.1, or 5.2.1.2 shoul be installed where the agent is?. Because I don't have control over that and I think that it will be impossible. Thanks,    Rafael.

I used tcpdump to watch the packets flow. You were right, when no changeover is done only 2 packets are transported during the session opening. After the changeover 4 packets are transport. Regarding the engineID, it is configured exactly with the same string in both snmp agents. The parameters e
