IPMITool Commands Not Working When Using Encryption Key
I'm able to remotely communicate with a server's BMC with the following command when the default "all zeros" are entered into the Encryption Key configuration.
sudo ipmitool -I lanplus -H -U chassis power status
Yet I get the following error when I use an encryption/kg key symetric pair:
sudo ipmitool -I lanplus -H -U -k -vv chassis power status
[...]<
<< Message tag : 0x00

Error: Unable to establish IPMI v2 / RMCP+ session

No Response from Get PICMG Properties
No PICMG Extenstion discovered

Unable to get Chassis Power Status
Using the Dell Troubleshooting Tool, I get "Connection Passed" when the encryption/KG Key is typed in.
Any suggestions as what I can try next?

Just looking at this now...
iDRAC uses hexidemial keys. So we expect to use -x option for ipmitool to work wtih keys.
Something like:
ipmitool -I lanplus -H 10.1.1.1 -U root -P yourPasswd -x 00AADD0000000000000000000000000000000000 chassis power status
Thanks,
Rob
