    Re: Ubuntu Server 18.04.06 IP Config.

    IPv4 and IPv6 are fairly different in how they work. Most everyone is familiar with IPv4 (with private,non-routable and public IP networks) but they are nearly maxed out on available IP addresses...
  2. [SOLVED] Re: Kernel upgrade - server keeps booting from old kernel

    Not quite. The going from 18.04 to 20.04 will yield similar kernels. The crux of the oddity here is how/when the OP got onto 5.6.

  3. [SOLVED] Re: Kernel upgrade - server keeps booting from old kernel

    But ONLY if the currently loaded kernel is not the 4.15 branch. Never purge an active kernel (not sure if it would let you though).

    One can check which kernel is loaded with the following...
  4. [server] Re: Ubuntu server - Nextcloud, firewall questions and some other stuff

    NextCloud is a PHP web application so it needs a web server and also a database server. I have used Apache and MariaDB.

    I tend to not utilize "apt install nextcloud" because that always installs...
  5. [ubuntu] Re: on 20.04 installing automysqlbackup problem

    I have never used "automysqlbackup" before. I wrote my own script for encrypted backup and decryption of user / system databases, users, roles and rights.

    I am glad you figured it out because I sure didn't know what to say about it. Congrats and thanks for letting others know how to resolve it too.

  7. Re: mysql-server not starting, can't make lock file ?

    I used to use MySQL until Oracle took over and basically halted development on it and made it stagnate. The original MySQL community developers forked the code to make MariaDB and at the beginning...
  8. Re: mysql-server not starting, can't make lock file ?

    Was this a functioning MySQL server or MariaDB server? Or are you trying to switch database engines or perform an upgrade?

    Curious what the most-likely action was that caused this issue.

    Also,...

    [server] Re: After kernel update no zfs

    I am about 90% sure. I have installed a lot of 20.04 servers but only with the legacy installer (Debian-based) and not the live installer version (not Debian-based).

    I looked over my old thread...

    [server] Re: After kernel update no zfs

    I don't use ZFS so I am not familiar with it. But I do know that ZFS is not installed by default on Ubuntu Server 20.04 LTS. That has to be added with "apt install zfsutils-linux"

    The kernel...

    Reboot and tell it to load the prior kernel. It will likely be corrected in the next kernel update.

  14. Re: 20.04.3 + Samba 4.13 + SSSD - Stop working after it was fine

    I will defer to others that actually run this kind of setup (I don't) but I recall needing to make sure the authentication method needed to be tied into PAM and if an update every reset the PAM...
  15. Re: 20.04.3 + Samba 4.13 + SSSD - Stop working after it was fine

    You are only looking at (or reporting) 1/2 of the puzzle. Make sure you look at the domain controller's event logs for correlating messages.

    I have had Windows updates break connections with...
  16. Re: /etc/security/limits.conf can only be deceased and not increased??

    Rather than make changes system-wide, you could apply them to a specific process. For example, I run a game server that touches a LOT of files due to how they designed their file system (lose files...

    Looking at "man screen" I see multiple references for encoding but only for setting "to" utf8. Not setting to anything else.

    Are you sure it was screen and not some other screen manager like...

    There are at least 2 methods for doing updates/plugin installs.

    The secure method has the web server / database permissions set to just the minimum for running the site which means you cannot use...
  20. [SOLVED] Re: Ubuntu Server using Winbind authentication instead of SSSD

    Seems like having a method to monitor changes to key files in /etc would be a good thing to have running...maybe not only detect write changes but also to email a report of what changed.

  21. Re: HA cluster - hearbeat vs pacemaker vs corosync, what combo is official?

    I cannot answer that question because I'm just a person that uses the various operating systems to accomplish what is needed (and many times I no say in what platform was used).

    Re: System Restore

    Well, you mentioned snapshots at the OS level. I talked about snapshots at a hypervisor level above the OS and then the Op started asking direct questions about virtualization. :)

    There is a lot of documentation out there to be found but I never found a "single source of truth" because there isn't one. The hardware used by each person will be different and will change how the...
  25. Re: HA cluster - hearbeat vs pacemaker vs corosync, what combo is official?

    You can achieve HA in a variety of ways with various levels of HA.

    Take for example a database-driven web server. You could have the database and website on a single server and have a 2nd one...
