[c-nsp] Retrieving running config via SNMP

[lee.e.rian at census.gov]

Hi,

I've heard good things about rancid, but if you really want to write your
own package the mib you're looking for is CISCO-CONFIG-COPY-MIB.
ccCopySourceFileType lets you specify startup or running config.

If all you're looking for is to be notified that the running config hasn't
been saved, take a look at CISCO-CONFIG-MAN-MIB.  It could be as simple as

  chgTime=`snmpget -Ovqt -m CISCO-CONFIG-MAN-MIB ${DEV}
ccmHistoryRunningLastChanged.0`
  savTime=`snmpget -Ovqt -m CISCO-CONFIG-MAN-MIB ${DEV}
ccmHistoryStartupLastChanged.0`
  if [ $savTime -lt $chgTime ]; then
     printf "%s config needs to be saved\n" ${DEV}
  fi

Regards,
Lee
