MySQL on Debian versions is configured differently than the native local MySQL plugin so you will be disappointed when your password on the mysql client fails by default.
Here is how you reset the MySQL root password the proper and "working way"
#first we gracefully stop mysql
sudo systemctl stop mysql;
#then we forcefully kill any mysqld process just in case
sudo killall -9 mysqld mysqld_safe;........
sudo usermod -a -G groupname username
It's really simple like above, the -a is for append so that you are not changing their main group, but adding them to another additonal group. Just change "groupname" to your group and "username" to the user you want to be added to "groupname".
A common task these days is getting your user access to kvm for virtualization so the KVM/QEMUprocess........
If you just do a normal chown user.user somedir it won't work. You will see the ownership is still the previous owner.
How To Change Ownership Of Symlink:
The simplest part is just adding the -h which means no dereference so it applies the ownership on the symlink and does not try (and fail) to change ownership of the dereferenced symlink destination.
chown -h user.user somedir........
Install Errors on Version 12:
This error happened on QEMU emulator version 2.11.1 pve-qemu-kvm_2.11.1-5
on Proxmox/Debian but installing on QEMU.12 on Centos 6 did not produce the error.
*Update it is not related to the OS or QEMU version. This happened in Centos 6 too after a second install.
What really causes this even though you successfully install........
The strange thing is that usually the first install or two will work on any new machine but then it suddenly won't. I had this experience on QEMU 2.13 on a different machine. There is something finicky or buggy about the CUCM installer even when choosing the same virtual hardware specs.

Ihave a directory structure which the primary user needs full access on but wanted a user to access only a specific directory within the main directory (so they could write in there only and nowhere else).
Here's what Idid:

This can be a case of bad permissions or modes as the error says. Normally one would assume permissions but often a script may change ownership of /root to something else.
This was the case half the time I've encountered this.
So in short make sure ownership is correct

Failed to load VMMR0.r0 (VERR_SUPLIB_OWNER_NOT_ROOT)
In most cases the error above is useful, it generally means /usr or /usb/lib or /usr/lib/virtualbox is not owned by root and this is the cause of the error.

This happened after a customer migrated their hosting and the issue was being unable to access PHP sessions.
Warning: session_start(): open(/var/lib/php/session/sess_3e0oms763m6mrqekdnnmodlhs3, O_RDWR) failed: Permission denied (13) in /register.php(202) : eval()'d code on line 1
Solution:(use the correct ownership/permissions)
chown apache.apache -R /var/lib/php........
This happens because of a permissions or ownership issue.
Generally /var/lib/mysql should be all owned by mysql.mysql (check that).
To fix it use chown -R mysql.mysql /var/lib/mysql
Also make sure the files are at least readable and writable by mysql (eg. 700).........

ntpd: can't open /var/lib/ntp/drift.TEMP: Permission denied
chown ntp.ntp /var/lib/ntp/
The solution is shown above and changes the ownership to ntp.ntp which is what the ntpd daemon/server is running as. This is based on Centos but the same idea will apply on any other OS. You can do a "ps aux|grep ntpd" to see what it is running as in the case it's running as a different user.

It's really silly how DA doesn't enable SSL by default but is otherwise a stable, fast and secure control panel.
Here's a copy and paste way of enabling SSL for Directadmin in just a few seconds:
openssl req -x509 -newkey rsa:1024 -keyout /usr/local/directadmin/conf/cakey.pem -out /usr/local/directadmin/conf/cacert.pem -days 9999 -nodes
That creates the public certificate and private key pair in the location Directadmin expects to fi........
*Make sure that the ownership is 501.501 or mobile.mobile when copying back (especially if using ssh or sftp as root on the iPhone) otherwise things will break. Eg. the contacts will be blank even after trying to update due to incorrect ownership/permissions.

This was done on Centos butI think it's easier on Debian machines, the paths that it is set to use are tailored towards Debian, so there is some fiddling that needs to be done on Centos.
This is for chrooting ssh, but jailkit has other uses than just SSH jails but I won't cover them in this writeup.

2. Setup Jail Home
