   1. Netdisco behind a Firewall (Christopher Doolan)
--- Begin Message ---
Hi Guys, the issue I am experiencing is that the Netdisco installed behind a 
firewall cannot connect to a test switch using netdisco-do -discover.

info discover: status defer: discover failed: could not SNMP connect to ...

However, the dev netdisco that I use at my desk is able to connect to the test 
switch using netdisco-do -discover.

                Info discover: status done: Ended discover for .....

This would appear to be a Firewall issue, however the switch has an ACL 
configure to limit what SNMP can connect to it and I am not sure if this is the 
problem even though both IP addresses are in the ACL.

What I would like to do is use snmpget to try and connect to the test switch 
from both Netdiscos, but I found that dev netdisco cannot be connect using 
snmpget, which complicates things.

Here is an example of the snmpget command I have been trying to use on dev 
netdisco.

                snmpget -v 2c -c [my community] xxx.xxx.xxx.xxx sysobjectID.0

Shouldn't this work if the community is the same as what is in the Netdisco 
deployment.yml?

                Device_auth:

-          tag: 'default_v2_readonly'

community: '[my community]'

read: true

write: false

What am I missing?

Regards
Chris Doolan
