Change IPMI cipher suite

[cstackpole]

Greetings,
I've successfully been monitoring a bunch of supermicro servers with IPMI on Zabbix 5.2. It seems the supermicro servers use the default of '-C 3' and are working just fine. The new servers are Intel and they will ONLY work with the '-C 17' cipher suite ID. Thus, all my Intel servers are getting:

cannot connect to IPMI host: [XXXXXX] Unknown error 33554433

If I drop to the command line:

$ ipmitool -I lanplus -H <host> -U <user> -P <pass> sensor
Error in open session response message: insufficient resources for session
Error: unable to establish IPMI v2 / RMCP+ session
$
$
$ ipmitool -I lanplus -H <host> -U <user> -P <pass> -C 17 sensor
<snip data - there's a lot of it>

I don't see anything particularly relevant in the debug logs. Just a failure that it can't enable the check.

How can I change the cipher level that Zabbix uses for these new hosts only?

Может проще включить id 3 на серверах intel?
по умолчанию отключено. или они совсем выпилили?

Thanks Hamardaban!

It seems that Intel is pushing hard on all new systems being set to the higher security level. Between the link you gave me and a bunch of reading on IPMI, I was able to learn enough to create a read-only user with permissions on -C 3 level that I was able to use successfully with Zabbix.
