With the Supermicro Embedded BMC, is it possible to connect to Serial Over Lan via SSH?
The ability appears to exist in systems running SMASH 1.04, but not in older versions such as SMASH 1.00 or busybox.
My experience is this: I was able to add SOL capability to a X8DTL by upgrading the firmware from version 2.23 to 2.43 with images downloaded from http://www.supermicro.com/support/bios/firmware0.aspx and uploading it to the HTTP interface of the bmc.
Note that the firmware versions vary significantly on different motherboards, but the SMASH versions seem to indicate the actual functionality available. (I have a X9DRL with firmware 1.88 that also has SMASH 1.04 and sol support.)
To access the serial console:
ssh ADMIN@<bmc-ip>
<input password>
cd system1/sol1
start
To exit the console, you need to press Enter, Esc, Shift-T
The console sometimes freezes up during POST or on reboot, so you may need use that key combo to exit the console. But overall the console here is much more reliable than the one accessible via IPMIView or the web interface.
Can you please let me know the exact version of BMC? Also, if you know the server / motherboard model number, that will be helpful. In my experience, its possible to connect to the SOL via the SSH if the particular IPMI card supports the feature. You will need to change BIOS settings to enable SOL interface. If you don't have a manual, you can download it from http://www.sentralsystems.com/support/
Supermicro has already released IPMI configuration utility, which you can download and try from ftp://ftp.supermicro.com/utility/IPMIView/
Once I will further information server/ipmi/motherboard number, I will be able to guide you further.
------------- Update: X8DT3-F motherboard does support SOL over SSH.
Here are the steps. 1.In SSH, issue “/usr/bin/smashclp” and it will launch SMASH 2.Change directory to /admin1/system1/sp1/textredirectsvc1 and give start command to start the SOL session via Smash
Other SOL features you can access from IPMI GUI from any web browser.
