Foreman » Smart Proxy

BMC LAN access works using ipmitool but I have to use the "-I lanplus" option.
Looking at my dpkg.log, I can see that rubyipmi has been updated from 0.6.0-1 to 0.8.1-1 recently (problably at the same time I updated foreman and the proxy).
I think this may be related.

Yes, 1.7 shipped rubyipmi 0.8.1 and it seems something changed in there from the 0.6 in 1.6. #7543 has some more information about how the smart proxy now supports additional options (1.8.0), which might let the lanplus option be sent, but Foreman itself doesn't have a way to enter these and it seems that this wasn't added to the smart proxy's configuration.

Ok, changing line 59 in modules/bmc/ipmi.rb and adding

{ :driver => 'lan20' }

I had a conversation with a guy on IRC and he had the exact same problem : lan (called lan15 in rubyipmi) method failed, lanplus (lan20) worked.

The 'lan' driver is related to very old BMC and considered insecure (auth is done using a clear channel).

Why not make the 'lan20' the default driver and get rid of the hack once Foreman has a proper way of setting bmc options per host ?

I have just made Rubyipmi 0.10.0 use lan20 by default. However the bigger question is since this driver selection is automatic in Rubyipmi there should not be a need to pass the driver type in the first place. I want to know why your server is different than all the others that have been tested against. If your error message is different than the one I am expecting to perform auto driver select that I need to see that error message otherwise this will fail. If you upgrade to Rubyipmi version 0.10.0 I would expect this issue to be resolved for you, however I would still like to see the error. #10112 will be necessary to specify options for some equipment, but the goal is not have add these details. So, if I know what errors your servers are spitting out I can automate the resolution in Rubyipmi without requiring everyone to specify additional connection options in foreman. There are some really good BMC additions in the smart proxy develop branch that will help with these issues.

Can you supply the error message when using some basic ipmitool commands without lanplus.

Corey: I can test different configurations if you want. Just tell me how to test it and I'll send you the reports. I think we should setup a different task/issue for this (in rubyipmi's github issues maybe ?) so we do not pollute this thread.
