All Linux servers are "Unclassified"

Hi,

i created discovery group for Linux boxes, where i put ssh credentials. It found the servers, but all of them are unclassified. What else do i have to input to get the discovered properly..?

Thank you.

    Thank you for your answer, i did try the T-Shooting tool and with the credentials i set, i get status "Connected". But in the console, the server is showing as unclussified.


    Maybe the rabbit hole is deeper then i thought.. :)

    Please let me know.

    Thank you.

    Thanks for the question.

    I hope your discovery range only checked the SSH box and not SNMP or any of the others :)

    There _might_ be a Troubleshooting Tool SSH test, I can't recall for sure.  This tool is installed on your OME desktop.

    It should be able to classify it just via SSH...I think we use dmidcode to do this.  Other folks use SNMP + OMSA for LInux.

    Hope this helps.

    does your box have dmidecode?  I would guess most distros do, but please confirm.

    Yes, only ssh is checked and filled with correct credentials.

    Ok, and sorry to ask again, but can you confirm that SNMP is _not_ checked in your discovery wizard?  Only SSH right?

    Hi,

    Can you also confirm the flavor of Linux server which you have?

    Also, can you check that firewall is not enabled for the SSH port and on the OME machine as well?

    Also,

    Can you confirm that the discovery task in using root user or some other user?

    And can you try running this dmidecode command on the linux server and see what is the output?

    dmidecode -t1 | grep PowerEdge –c

    we are using ssh on daily basis, so ssh firewall is i believe out of question, but firewall setup on aOME machine.. what should i be looking for..? OME is running on Windows VM.

    Thank you.

    Although, is it only linux discovery which is not working or none of the discovery tasks are getting classified properly? If it is only SSH discovery of linux servers, then it is highly doubtful that it can be a firewall problem.

    Can you confirm the flavour of linux, if it is a SLES, you may need to check the sshd_config file and the value of "PasswordAuthenticalion" needs to be made YES. By default it is NO.
