Hi,
I have an issue in proxy setup.
Running version of snmpd server is 5.4.pre3, hosted on firewall appliance
(McAfee Firewall, OS is a custom version of BSD).
I have a client (client, 10.253.37.71), a proxy SNMP server (swlab-c01,
10.253.37.83) and a remote server to be queried (remote, 172.30.25.10).
By GUI I set up v3 authentication, and I'm able to query the proxy SNMP
server from the client.
# Main snmpd.conf configuration file
syslocation "lab"
syscontact "[email protected]"
authtrapenable 2
com2sec publicUser default public
group public2Grp v2c publicUser
access public2Grp "" v2c noauth prefix _all_ none none
group monitorGrp usm monitor
access monitorGrp "" usm noAuth prefix _all_ none none
[root@client ~]# snmpget -v 3 10.253.37.83 .1.3.6.1.2.1.1.5.0
SNMPv2-MIB::sysName.0 = STRING: swlab-c01.example.com
In order to proxy SNMP requests to a remote server I added the following
line:
proxy -Cn dmz-172.30.25.10 -v 2c -c public 172.30.25.10 .1
When I specify the context, it doesn't work:
[root@client ~]# snmpget -v 3 -n dmz-172.30.25.10 10.253.37.83
.1.3.6.1.2.1.1.5.0
SNMPv2-MIB::sysName.0 = No Such Object available on this agent at this OID
I cannot solve this issue by mysef, may someone tell me where I'm making
mistake?
Notes:
1. queries the remote server get a response
[root@remote-server root]# snmpget -v 2c -c public 172.30.25.10
.1.3.6.1.2.1.1.5.0
SNMPv2-MIB::sysName.0 = STRING: remote-server
2. I tested the same setup on a linux box (Net-SNMP v. 5.1.2), and it works.
Thank you
Marco
