Re: [Pysnmp-dev] Pysnmp: Can it receive snmp v3 trap with random engine id

[chengkeke <che...@16...>]

Hi Ilya & all,


Now, I can get snmp v3 trap base on examples of v3 in pysnmp web site. I used the version pysnmp-4.1.10a. 


Here are my new questions.


1. There two network card in my computer. If set host as 127.0.0.1, local IP is 192.168.0.100, can't get trap information. After I change host to 192.168.0.100, it works well.So we can't set host as 127.0.0.1(want to receive all traps sent to local computer), is it correct?
2. In the sample, we only get name, val in varBinds. Can we get other information, for example, sec-name, auth protocol, auth key, privacy protocol, privacy key and agent ip address? [We can get details information in v1.] In pysnmp\proto\api, we only have v1 and v2c. 


Thanks all.
