Exactly.Is there a key generator in intermapper if I provide it with device ID?

It is possible that the Alcatel-Lucent documentation expects you to enter either the "Block" or "Localized" key into InterMapper, instead of an ASCII key. Here is some background: On a typical SNMP agent (e.g. Net-SNMP), you configure the auth and privacy keys as ASCII in a configuration file. You type these same ASCII keys into InterMapper and the SNMPv3 connection "just works". However, the SNMPv3 protocol does not *directly* use the ASCII keys you enter. Instead, the ASCII key is first converted into a "block" key by running the ASCII password through a one-way hashing function several times. Then, this "block key" is combined with the unique SNMPv3 engineID of the target device to produce a "Localized Key". This localized key is different for each device, and it's the key that is actually used to authenticate/encrypt SNMPv3 payloads. ____________________________________________________________________ List archives: http://www.mail-archive.com/intermapper-talk%40list.dartware.com/ To unsubscribe: send email to: [email protected]
