1. Let's work from an environment where we can install Ansible on.
Requirements: A Linux machine (eg. VM whether in the Cloud or a local VM on Vbox/VMWare/Proxmox) that you can easily install Anisble on (eg. Debian/Ubuntu/Mint). The VM requires proper/working internet between the Ansible Controller and to the internet.
This will be on our "controller" / source machine which is where we deploy the Ansible Playbooks (.yaml) files from.........
Volume control will often stop working, if your sound server (normally pulseaudio) dies or restarts whether by itself or by you. The reason pulseaudio may need to be restarted is due to some sort of crash or other issue that prevents sound from working (normally restarting or doing a killall pulseaudio fixes things).
However, you will normally find at least in OS's like Ubuntu/Mint 16/18+ that you cannot control the volume whether adjusting the level, changing input/outputs and........
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........
So you restarted your router/dhcpd server or for some other reason you wonder why DHCP is not working on any of your clients?You go and check that named is in fact running fine.
But then you check /var/log/messages and see this error for everything hostname:
named: error (broken trust chain) resolving 'min-api.cryptocompare.com/A/IN': 22.214.171.124#53
I've only ever seen this when the time on the server was off. It........
The solution is simple but strange, if you copy your /var/lib/mysql directory to another server and think it will work, be sure to check if you have /var/log/mysql and binary log files. If you do, the server will not work and will give you errors like below and crash without the proper log files.

Just in case anyone is wondering that is the case, it can make troubleshooting impossible if you're making changes to php.ini but don't realize the webserver must be restarted for those changes to apply (contrary to running php-cgi which always looks up the current .ini settings).........
This example involves an Aterisk message log of about 26GB, but with any server it usually does not get deleted until the server is stopped/restarted:
asterisk 13729 root 6w REG 0,41 27277943090 59097971 (deleted) /var/log/asterisk/messages
So if you've deleted a bunch of large logs, make sure you restart the server for them to regain your space.
iptables v1.3.5: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
This solution applies to all other iptables modules/problems for OpenVZ, you'll just need to add them to both lists/lines below if you have modules other than what I have below.
The modules need to be enabled in both iptables and the OpenVZ hostnode itself and then the containers which need it must be restarted.
How To Enable IPTables Modules in OpenVZ........
The normal solution would be as follows:
But what happens if that doesn't work? I haven't been able to find much documentation about how to find the list of displays and how their numbering works in Xorg.
Sometimes you'll get this error when trying to restart vino:
Cannot open display:
For some reason my display is not on 0.0........
This may not apply to everyone but here is what happened to me.
One day my IP connectivity for one container went dead, I could ping the hostnode from it and the hostnode could ping it but there was no external routing. I restarted the network service but it didn't help.
I checked the routing table inside the VPS and the host and everything looked normal. Iadded another different IPon the same subnet to the container and it worked. Right away I st........

crontab not working
It is running as user Apache
I've tried 0 0 * * * (which means midnight 00:00) and it does run at midnight but also 13:25 for some reason?
25 0 * * * with this it runs at 00:25 but again also at 13:25
Solution - Restart the Cron Service (especially if you changed your time/timezone)

I've only used it on Centos, soI thought I'd make a quick Debian guide:
Install the DRBD Package
apt-get install drbd8-utils
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages were automatically installed and are no longer required:
Use 'apt-get autoremove' to remove them.
It simply doesn't work, the Apache VHOSTS remain 100% unchanged, why does this script exist? I'm sure it would work from the control panel but I am locked out because my IP was changed and it doesn't match the CPanel license. I wish CPanel would make it easier to update the license IP.
I even took it a step farther, I manually edited the vhosts and restarted Apache and it........
This is what the /var/log/cups/error.log says after my Samsung CLP-310N decided to stop printing. This is a new printer that replaced my CLP-300 and it has been working for a day so far.
What happened is that I lifted the top part (not realizing there were rollers on it) and it stopped printing. The network activity light was flashing ,hitting the stop button didn't do anything. Even powering the printer on and off did not help.
I have restarted CUPS and SMB on the........
Asterisk FreeBSD compile problemsI couldn't get it to compile without using the following options at compile time:
make install WITHOUT_ZAPTEL=YES WITHOUT_MYSQL=YES WITHOUT_FAX=YES WITHOUT_ODBC=YES WITHOUT_H323=YES[/b:b7d672ee28]Some problems you might have with copying over your Linux config files to FreeBSD is different paths.

I wanted to disable the "Administrator" account for security purposes and Iread some "guide" on the internet that recommended that we run "C:WindowsSystem32sysprepsysprep.exe /generalize". I also clicked the option for "Generalize" and the computer rebooted and gave some OOBE error and restarted, and now I get the error above no matter what.
I read that some drivers such as ones from AVIRA AV can cause this because they're unsign........
I didn't find any useful information that actually fixed this. My VPS was in the "Running State" and I could not stop or restart it. I kept getting "Container already locked" no matter what Idid (I tried all the suggestions in the Google results for this error).
Most of the suggestions were for Windows but I only use Linux. The other solutioins also said to restart the VZ service or even the entire hostnode and this was not acceptable to me........
To enable Fuse to work inside a OpenVZ container it's very simple (although some people say it can't be done).
Remember that on your HN(HostNode) for OpenVZ, Fuse must be installed and the module must be loaded for this to work. In addition remember that you need the Fuse package installed inside the container of course.

Server not using user level security and no password supplied.
tree connect failed: NT_STATUS_WRONG_PASSWORD
That happens when trying to use smbclient to connect to a share. The weird thing is that I can authnenticate just fine from Windows XP.
It is partially my mistake, I forgot this share does have a password. I've tried authenticating with the correct user and also with "Guest" because this works in Windows. In Linux I ........
