The "snmpbrowser" package isn't our code, so we can't really comment.
You'll need to talk to RedHat or the author about that.

Please see the FAQ entry:
I can see the system group, but nothing else. Why?
This is definitely a problem with the access control settings - nothing
to do with
snmptranslate.

Yes. Got it in one.

Because the access control settings don't allow access to them.

"Changed some things" isn't particularly helpful in knowing what's going
wrong.
If you're reporting problems, it's worth being as exact as possible.
The more we
have to guess, the more we won't bother :-)

Start as simple as possible.
Create an snmpd.conf file containing *just*
rocommunity cvv_test
and run the agent using that.
Can you see the system group ("snmpgetnext -v 2c -c cvv_test
{agent_host} system") ?
Can you see other groups ("snmpgetnext -v 2c -c cvv_test
{agent_host} ip") ?
If that works (and *only* if it works), add the 192.168.2.0/24
limitation, and try again.
