    Check the status of ufw

    What's "ufw" ?

    In any case, I had to call my hoster so the server was reset completely, since I could not log in via ssh anymore, or do anything, for that matter...

    After it happened for a second time, I changed to an hoster provided image with ubuntu + plesk.

    But actually I'd like to use the ISPConfig3 setup provided in the tutorial, but if I can't log in from one moment to another, it is kind of pointless....

    ufw is a program for managing a netfilter firewall

    It means that after restart the "ssh" service is not start -up boot.

    Add it in startup as

    The ssh demon was in the start, as was apache, and dovecot and so on. Like I said, the server worked seemingly fine - as with the tutorial above.

    However, without any reason (at least none I could find) the server had all ports closed after a 'reboot' command.

    No, apache, no dovecot and no ssh.

    My hoster provides a rescue system, which I then booted, and logged in to, but I could not find anything odd.

    Since this happened twice - every time after I had set up the server, created profiles and so on, I though maybe it is a known phenomenon.

    It means that the firewall gets started with the reboot

    & then chek the status after restart

    Would there be a way to achieve that, from the rescue system?

    Meaning, if I only have access to the file system, where would I make sure the firewall isn't loaded ?

    And why would the firewall activate itself anyways. It didn't all these reboots before...
    And the tutorial clearly status, that ISPConfig3 comes with it's own firewall.

    UFW is prenative firewall with a debian/ubuntu. It is always in deny mode by default But sometimes it gets activated may be due to some installations, so better to either remove or de-activate ufw.

    To deactivate it you can use

    Thanks for the info.

    I'll retry to setup the server with this in mind later this month...
