Accessing Supermicro IPMI via SSH

When you deal with Supermicro IPMI/BMC, you could access it via:

  • HTTP(S) in your browser - seeing web pages with sensors/configs and java applet to run redirection console
  • IPMI protocol (using ipmitool-like CLI or IPMIView-like GUI apps)

Once I discovered I could just ssh [email protected] and get into the BMC - there is Linux-like shell, ifconfig (not with server's, but with BMC's network settings), and - the greatest thing! - ability to tape reboot to reset BMC when IPMI starts glitching.

But now, having access to numerous Supermicro boxes with IPMI, I discover that SSH access works differently: about a half of boxes runs "normal" shell on IPMI's 22 port, other runs the "ATEN SMASH-CLP System Management Shell". It is not Linux-like, not supports standard commands like ls, and I can't reset BMC with it.

Google mainly says of SMASH-CLP in source-of-security-breaches way. Is there any user documentation for it? Or could I make my IPMI/BMC run "normal" shell via SSH, not SMASH-CLP?

I deal with X9DRW-iF, X9DRi-F and X9SCL-F motherboards.


Solution 1:

On all my Super Micro BMCs there is a hidden SMASH command to drop out of the default environment and into a BusyBox shell.

Try typing "shell sh" in the SMASH shell and see if that works.
