OpenCompute IPMI with F11 / F12 Issues

These are more notes than a real blog post.  Working with IPMI on OpenCompute has weird quirks and one of those is the Serial BIOS with the F11 and F12 keys.

Here’s an example of using ipmitool to pull information remotely about the power status

$ ipmitool -C3 -I lanplus -H 172.16.56.180 -U admin -P <password> power status

Using the Serial BIOS

The serial BIOS interface is a bit brain damaged in that it does not recognise the “F11”, and “F12” key escape codes that most terminal programs send, instead you can send “Esc-!”, and “Esc-@” (yes very logical, as long as the ‘@’ key is normally typed using ‘Shift-2’ – as on US keyboards, not miles away from the ‘2’ key, as on many non-US keyboards).  These escapes from HP, and Dell serial BIOS’ may or may not be useful:

Defined As     F1     F2     F3     F4     F5     F6     F7     F8     F9     F10    F11    F12
Keyboard Entry <ESC>1 <ESC>2 <ESC>3 <ESC>4 <ESC>5 <ESC>6 <ESC>7 <ESC>8 <ESC>9 <ESC>0 <ESC>! <ESC>@

Defined As     Home   End    Insert Delete PageUp PageDn
Keyboard Entry <ESC>h <ESC>k <ESC>+ <ESC>- <ESC>? <ESC>/

Use the <ESC><Ctrl><M> key sequence for <Ctrl><M> Use the <ESC><Ctrl><H> key sequence for <Ctrl><H> Use the <ESC><Ctrl><I> key sequence for <Ctrl><I> Use the <ESC><Ctrl><J> key sequence for <Ctrl><J> Use the <ESC><X><X> key sequence for <Alt><x>, where x is any letter key, and X is the upper case of that key

Setting up TomatoUSB for VLANs and Ubiquiti AP

So after getting a quarter of the way through a comment to a question somebody had on my Ubiquiti APs, TomatoUSB, VLANS, and Linksys e3000 post, I realized it would probably work better as a post instead. Christoph’s question was:

How did you wire everything? I’m trying to do the same and had no luck. I only have one UAP, but if I turned on tagging for the Port I used for each bridge, I wouldn’t even get an IP.
I would like Management and Home to be one vlan, and guest another, so my setup is simpler. Maybe knowing how you wired it will help.
Thanks!

I’m going to walk essentially through what steps I remember taking to get up that far.

Assumptions

  • VLAN 2: Home / Management
  • VLAN 3: DMZ
  • UAP plugged into Port 1
  • Admin Computer plugged into Port 4
  • Management / Home network is 192.168.1.0/24
  • Guest network is 192.168.2.0/24
  • You have a VLAN edition of Toastmans TomatoUSB mode

Compiling Intel’s Data Center Manageability Interface on 64-bit

I needed to use Intel’s Data Center Manageability Interface program to interface with IPMI that does not have a dedicated controller, so we needed to use software emulation. Two issues that we had were:

  1. The binaries provided on their website didn’t work due to needing older libraries that had deprecated functions in them.
  2. Source code didn’t compile because of those same libraries that were missing.

I’m including a patch for DCMI_Conformance.cpp that will allow it to compile on Ubuntu 12.04 64-bit. The source came from ipdc-1-5-0-31-0-src.tar.gz, which was downloaded from Intels site. Just make sure that you have the dev libraries installed for ncurses and libssl.

RocketRaid 622 Driver (rr62x) for Ubuntu Linux Kernel 3.8

More of a reference for myself so that I don’t have to go through this again, but I put together the patches people had in multiple places so that I can install rr62x-dkms on my 12.04 system. Probably a better way to do this, but I’m tired and just wanted to get the system up.

File: rr62x-dkms_1.1_all-3.8.deb
