Cant access Extreme Stack using SSH any longer

    Hi All,
    We can no longer access the Extreme Stack using SSH and can only access using the GUI. Everything was working before. Any suggestions guys, please?

    Regards,

    Hello Mykhaylo,
    Are there any error messages presented when you try to SSH to the switch?

    What version is running and what model switch?

    Can you restart the ssh process from the GUI?
    Can you enable telnet from the GUI? Then telnet to the switch to restart the ssh process.

    Is the ssh xmod loaded on both partitions? I have seen the xmod get left off a partition which will cause ssh to fail if the switch boots from that partition.

    Best of luck

    That was a question. I don't know if it is even possible.

    The switch model and code could affect the answer. If you can provide that it would help the TAC guys answer questions.

    Hello All,

    Ok got some more info:

    EXOS 15.6.4.2
    Hardware X440-48p

    Error is connection refused:



    ssh: connect to host 10.10.15.252 port 22: Connection refused

    While trying to ssh.
    Just a note I have a console access into the switch. How can l safely re-enable ssh module?

    Thanks,
    Mykhaylo

    Hi All,

    restart of the ssh process did a trick:

    restart process exsshd

    Thanks all for the help.

    Take a look at this topic: https://community.extremenetworks.com/extreme/topics/ssh-access-stops-working
    To restart SSH, use the
    code:
    restart process exsshd
    command from the console.
