    I just use the Live Ubuntu 14.04.4 Desktop CD. Just boot from the iso and Select "Try Ubuntu" and it won't touch your system files at all (runs in memory). But, try restarting the ipmi service as I mentioned above first :)

    Trying to restart the ipmi service gets me - "ipmi: unrecognized service". :(

    I have Mint up and running on another computer but how is doing this remotely different?

    Doing it remotely is obviously interacting with IPMI on the remote system vs. the local system. It does not require IPMI to be working locally or modules to be loaded either.

    The previous commands I mentioned have worked great remotely on two separate X9SRL-F boards.

    running Mint on the system in question I couldn't get to the desktop. I got an error and then a command prompt. This was ok because the command prompt worked. Now that I have Mint running on a remote system I'm at the desktop but the commands don't work in Terminal. I get "segmentation error". What am I doing wrong?

    Thanks

    Do you have a working network and have you installed the impitools package?

    It really isn't that difficult but you still don't have an IPMI device to talk to (/dev/ipmi0). So... reboot, if practical, to get a clean start and run:

    reset; sudo modprobe -av ipmi_msghandler ipmi_si ipmi_devintf; lsmod | grep ipmi; dmesg | grep ipmi

    Show us the output. And it's sudo ipmitool sensor when running it locally.

    Also, Linux Mint is a bit of a mess. Stick to Debian or Ubuntu if you want a Debian flavour.

    When I try to install ipmitools (sudo apt-get install ipmitools) I get the error I mentioned above. I was able to run these commands from the computer in question when it wouldn't load the desktop but now on a second computer where the desktop does load, the commands don't work. Sorry, I don't know why. :(

    Network is irrelevant when using IPMI locally and it's only relevant for the BMC when using it remotely.

    He was trying to do this remotely now, so networking is important.

    GHDFC... I'm on Ubuntu now and when I try to install ipmitool I'm getting "ipmitool is not available but is referred to by another package, blah blah blah. :(

    Found these instruction on another site but try to run them I get "Operation not permitted" :(

    modprobe ipmi_si
    modprobe ipmi_devintf
    echo ipmi_si >> /etc/modprobe
    echo ipmi_devintf >> /etc/modprobe

    apt-get install ipmitool

    test

    ipmitool -I open channel info

    There's ipmiutil for Windows, if that's easier.

    Have you performed a blood sacrifice yet?

    Are you facing East? Have you sprinkled Holy Water on the motherboard? Do you know a Priest, Pastor, or Rabbi?

    I have that but it was my understanding that ipmitool was the only way to change fan thresholds.

    I'm not religious so beer, wine and whiskey will have to suffice.

    That should definitely work?!?!

    Code:
    root@fileserver:~# apt-cache search ipmitool | grep ipmi
    ipmitool - utility for IPMI control with kernel driver or LAN interface
    
    This is on an Ubuntu 14.04.4 server.

    Thank you sir. I've quit for the day and am now chillin' with a beer. Will give it a try in the morning.

    I did hook up a fan controller just to see if it would work and it does. I put 2 humongous Scythe fans in it and can control the speed from silent to wind noise, not too loud but can be heard. And no more oscillating between low and full blast. The reason for all this is because my CPU temps are on the high side, upper 50's at idle. I've got a pair of SM active coolers on the way. Seems these Dynatrons just can't cut it. Right now one is a 42 and the other is at 50. That's with the 2 Scythe's barely audible. Temps drop even more when I crank them up. I'd rather have the MB control the fan speed but I'll settle for what I have if need be. The dynatrons are very quiet, can barely hear them when the room is quiet, but they just don't cool very well. The 2 Scythe's are awesome fans, they push a tremendous amount of air and do so as quietly as it gets. Highly recommend them.

    You're still not root while trying to run privileged operations. Take Introduction to Linux.

    Linux sucks. I'll just use the fan controller.
