Yes, I've done that all. I don't use RMM4, thus I only configured the first IP group (the RMM4 group is greyed out). Addresses for my network are 192.168.1.205 / 255.255.255.0 and 192.168.1.1 for GW. All users are enabled and configured with a password.
The configuration is verified using ipmitool in Ubuntu. Ipmitool correctly lists all five users, and password test also passes.
What remote tool should I use?
