# SNMP Proxy
|
|
|
|
If you have machines that you want to monitor but are not reachable
|
|
directly, you can use [SNMPD
|
|
Proxy](http://www.net-snmp.org/wiki/index.php/Snmpd_proxy). This will
|
|
use the reachable SNMPD to proxy requests to the unreachable SNMPD.
|
|
|
|
## Example configuration
|
|
|
|
We want to poll 'unreachable.example.com' via
|
|
|
|
'hereweare.example.com'. Use the following config:
|
|
|
|
On 'hereweare.example.com':
|
|
|
|
```
|
|
view all included .1
|
|
com2sec -Cn ctx_unreachable readonly <poller-ip> unreachable
|
|
access MyROGroup ctx_unreachable any noauth prefix all none none
|
|
proxy -Cn ctx_unreachable -v 2c -c private unreachable.example.com .1.3
|
|
```
|
|
|
|
On 'unreachable.example.com':
|
|
|
|
```
|
|
view all included .1 80
|
|
com2sec readonly <hereweare.example.com ip address> private
|
|
group MyROGroup v1 readonly
|
|
group MyROGroup v2c readonly
|
|
group MyROGroup usm readonly
|
|
access MyROGroup "" any noauth exact all none none
|
|
```
|
|
|
|
You can now poll community 'private' on
|
|
'unreachable.example.com' via community 'unreachable' on host
|
|
'hereweare.example.com'. Please note that requests on
|
|
'unreachable.example.com' will be coming from
|
|
'hereweare.example.com', not your poller.
