MRTG help please

[jayjay66]

Hi,

I'm trying to install MRTG but I get an error stating that there is no such name or no response from my community name. I used "public" but I think it's wrong. how can i verify what my community name is exactly ?

thanks,
jj

Look at the configuration of the device you're querying. The community string is basically an SNMP password. If you don't know it, SNMP won't be able to tell you.

i have the correct community name string but it still says host not found. any help please.

snmpwalk -v 1 -c <community> <host>

If you get a bunch of output, then you have the right values for <host> and <community>. If not, it'll probably help narrow down any problem with SNMP.
