Hi IPMI experts,
On some older machines (e.g.IBM x3650) I failed to do IPMI remote
management with "lan" or "lanplus" option:
# ipmitool -I lanplus -H 10.0.8.26 -L ADMINISTRATOR -U xxxxx -P xxxxx
lan print 1
Error: Unable to establish IPMI v2 / RMCP+ session
Get Channel Info command failed
While I can do it locally with "-I open":
$ ipmitool -I open -H 10.0.8.26 -L ADMINISTRATOR -U xxxx -P xxxx lan print 1

I am not sure if it relates to the cipher suites, or if it's supported
in the suites.
I tried to change the cipher_privs to something like aaaaaaaaaaaaaaa as
a test, it returns:
$ ipmitool lan set 1 cipher_privs aaaaaaaaaaaaaaa
LAN Parameter Data does not match! Write may have failed.
I could only change the first 5 'a's (aaaaa..........).
Does it mean that it only support limited cipher suites?
Or is there anything else I can do to implement the remote IPMI
access/management?
Thanks,
Erming
