'exit' command does nothing.

logout, quit, … are not valid commands.

Switch revisions A1 and B1.

Latest firmware installed: V2.80(AAHI.0)C0

    Hi @zymat6816,

    The "exit" is used to exit the current mode only. Currently, GS1900 does not have a command to exit the SSH session. What SSH software did you use that needs a command to exit the SSH session?

    Hi.

    I am using oxidized for configuration monitoring, works well for every other type of equipment that we have. It is based on Ruby.

    Hi @zymat6816,

    After investigation, we found the exit command was malfunctioning on this firmware version, that it should exit the SSH session. We will fix this in the future firmware release. You may follow this category to receive the new firmware release notification.

    Hello,

    seems that GS1920-8HP has a similar problem … exit command does not terminate the SSH session.

    Current ZyNOS version : V4.80(ABKZ.1) | 07/08/2024

    Hi @zymat6816,

    I use your model and firmware version but cannot reproduce your issue. What SSH terminal software are you using? I tested with Tera Term.

    Hello,

    my intention is to include GS1920-8HP in Oxidized configuration monitoring - which has a problem with it.

    To test, I made a SSH session with Putty: after a succesfull login I typed 'exit' command which made the session "inactive", but did not close the window as it normally does. As soon as I typed any key (like space) I was back in session.

    Then I also made a new session from another linux box; after 'exit' command it produced unusual message:

    zyxel# exit
    packet_write_wait: Connection to x.x.x.x port 22: Broken pipe <IP removed>

    linux:~ $
