Re: mrtg problem

I was setting up MRTG on a Debian box and everything was proceeding well for
almost a day.  However, now one of the routers appears to be giving a
problem.  I get this:

SNMP Error:

  error status: noSuchName

This router was responding fine, like I said for almost an entire day.

Any ideas what is causing this and how I can fix it?

Did you try a snmpget by hand from the machine running mrtg? E. g. :

  $ snmpget -v1 host community-string snmp-object

In your case, seems to be :

  $ snmpget -v1 xyz ""
