I am assuming you are referring to the snmpInBadCommunityNames variable (full path is .iso.org.dod.internet.mgmt.mib-2.snmp.snmpInBadCommunityNames, and the OID is .1.3.6.1.2.1.11.4). So the heart of the loop would contain something like:
snmpget -v 2c -c putyourcommunitynamehere puttheipaddresshere .1.3.6.1.2.1.11.4 Depending on whether the devices are using SNMP version 1, 2c, or even 3you will need to change the -v option. If you wish to do it in Perl you would probably want to use the Net::SNMP module, which is documented at http://search.cpan.org/~dtown/Net-SNMP-5.2.0/lib/Net/SNMP.pm . You of course would need to know the addresses or hostnames in advance, as well as the community string(s). There isn't, to my knowledge, a simple way of discovering which boxes are running SNMP without already knowing the community string and the SNMP version number, since SNMP won't respond if anything is incorrect with the SNMP query, so simple nmap scans don't work very well. -------------------- BYU Unix Users Group http://uug.byu.edu/ The opinions expressed in this message are the responsibility of their author.
