    Thanks to both of you.

    I read about ssmtp before, and it looks like a good and lightweight option that I'll look into some more
  4. [SOLVED] Re: How to send email using another postfix server on the network

    So just to understand your point, you have to install postfix (or something similar) on all servers, even if my "satellite" servers should use the central postfix server to actually send the mail off...
  5. [SOLVED] How to send email using another postfix server on the network

    I created a shell script that can download and install keys to be used with [signed-by=] declaration in sources.list.

    [SOLVED] Re: Apt-key deprecated

    I think the long-term solution here would be to create a script that:


    Checks if the key is ASCII-armored - and dearmor if that's the case

    Please explain this - what do you mean, where did Teamviewer come from?
  12. [server] Re: Ubuntu Server 20.04.02 repeatedly freezes/crashes. syslog pastebin inside.

    The only solutions I can come up with are either:


    Reduce "swappiness" if it's because of swap activity
    Run fewer jobs that require disk I/O

    But you should definitely monitor the disk I/O...
  13. [server] Re: Ubuntu Server 20.04.02 repeatedly freezes/crashes. syslog pastebin inside.

    You have I/O errors on your NVME disk, which also causes system jobs to hang in the kernel for more than 2 minutes. I definitely think you have some kind of problem with the NVME disk - or maybe it's...

    Fine - but do you need multipath at all? If not, you can as well disable the service and blacklist all devices to prevent future syslog spamming.

    I would suggest you edit the file /etc/multipath.conf like this:


    defaults {
