Re: Warning: Cisco RW community backdoor.
It appears more than one vendor shared the same SNMP library (or SNMP programmer). Folks have sent me evidence at least two other vendor's equipment has similar responses to the same SNMP community string ILMI. However, there are other non-related SNMP issues. Many SNMP implementations included the default community strings "public" and "private". If the operator doesn't change them, the defaults may still work. The other common SNMP implementation issue is if no community string is specified, the SNMP agent accepts any community string. If you are checking your network, I'd suggest checking for all three possibilities.
