C2100 BMC SSH access

Is this possible?  If so can someone help with the configuration of this?

Thanks

    Hello Effyis

    SSH is possible on the C2100. It is only available through Serial Over Lan though:

    To enable SOL refer to page 20 of the BMC user's guide:

    Thanks

    I have everything configured but I'm getting a connection refused error when I try to connect by ssh.

    The web interface is still working.  I've tried com1 and com2 as well.

    This document also has some good info about SOL and management features on the cloud series:

    http://poweredgec.com/files/QSG_PowerEdge_C_System_Management.pdf

    Go back to the SOL settings in the BIOS and change the port to COM2, also set the speed/baud rate to 9600.

    What kind of cable are you using DB9 to USB, straight or crossover, etc?

    Thanks

    I have those SOL settings.  I've tried two different cables, just an Ethernet cable.  I have the BMC set to dedicated for network.

    The I also tried a serial -> Ethernet cables that came with one of our switches.

    I'll have to check and see if we have a cloud server in our lab, and test this tomorrow.

    You should simply be able to telnet/ssh into the assigned IP address of the SOL connection. Unless you have a separate setting for the SOL connection it will be the same IP address you assigned to the remote management interface.

    I'll see if I can get some equipment tomorrow to test with.

    Thanks

    Thanks for your help.  We have 18 of these servers.  Our admins, who are from Russia, want to be able to SSH directly to them, in case of issues with the server.

    Everything sounds like it should be working. Try lan instead of lanplus. If you get a different error, or it works let me know.

    Read through this doc and see if we missed anything:

    I am trying to connect from the same server as the BMC, it can ping it, and I can connect to the web interface from another server.  There is no firewall stopping internal traffic, so all ports should be fine.

    Looking in the web interface I can see that IPMI over LAN is enabled and SOL is enabled.

    Maybe I need to go into the bios and verify the settings of com2?

    Yes, it should just be connected to the network with a normal straight through cable. Is port 22 blocked on your network anywhere?

    Are you able to connect via the web-based GUI on that IP address? If you can connect to the GUI then it is likely one of these issues:

    • SSH or SOL port is blocked(should be 22 and 2100)
    • SOL is not enabled(Double check to see if the changes were saved)
      • I had to enable IPMI over LAN in the DRAC BIOS(CTL E), and SOL in the regular BIOS(F2). You may have to do the same
