[mrtg] Re: Problem with SNMP?

[Paul C. Williamson]

So it looks like SNMP is not enabled on this device or 
you do not have the correct community (public in your 
example) string.  What kind of device is this?

Don't even worry about snmpwalk until you can get it 
either working or find out the community name.

Hello.

I try this cfgmaker command:
cfgmaker --global 'WorkDir: /var/www/html/mrtg' --global 'Options[_]:
bits,growright' --output /etc/mrtg/mrtg.cfg public at 10.52.4.221

and here is output:
--base: Get Device Info on public at 10.52.4.221:
SNMP Error:

Because I'm beginner in using SNMP, I don't know, how can I use snmpwalk
command. :-(
