In this example we are adding IP 192.168.1.235 (also we mention GW and DNS for it ) and removing the IP 192.168.1.233
nmcli connection modify ens18 ipv4.addresses 192.168.1.235/24 ipv4.gateway 192.168.1.1 ipv4.dns 8.8.8.8,1.1.1.1
nmcli connection modify ens18 -ipv4.addresses 192.168.1.233
service NetworkManager restart
nmcli connection reload
for i in $(awk '{print $2}' /etc/trueuserdomains); do uapi --user=$i Email list_pops | egrep "\s+email:" ; done

Check if FB bot is present:
grep -c "facebook.com/externalhit_uatext.php" /etc/apache2/logs/domlogs/*/*|awk -F'/' {'print $7'}|awk -F: {'print $2,$1'}|sort -k 1
Block whole FB bot network:
yum install -y whois;for i in `whois -h whois.radb.net -- '-i origin AS32934' | grep ^route |grep -v route6|awk {'print $2'}`;do csf -d $i "FB bot network https://developers.facebook.com/docs/sharing/webmasters/crawler/#crawler-rate-limits";done
f you need a quick way to find out how much RAM your Linux system supports or to determine the number of DIMM slots available, you can use a command line tool called dmidecode.
dmidecode command is a tool for dumping a computer’s DMI (some say SMBIOS) table contents in a human-readable format. Thanks to this table, you can retrieve this information without having to probe for the actual hardware.
# archlinux
yaourt -S dmidecode
# ubuntu
sudo apt-get install dmidecode
To find out the maximum RAM capacity and the number of RAM slots available, use the following command:
sudo dmidecode -t 16
The Maximum Capacity is the maximum RAM supported by your system, while Number of Devices is the number of memory (DIMM) slots available on your computer.
To see complete memory information, including the info above along with currently installed memory information (RAM speed, size, etc.), use:
sudo dmidecode -t memory

* First create a new KVM with a Harddisk. I used a QEMU-Disk
* Start the VM with a Linux-Live-ISO
* Create the following partitions:
– Linux boot (ext2/3)
– Linux Data (i.e. ext4)
– swap
*set the boot-flag on the boot-partition
* shut down the KVM
* connect to host-console – I preferred to login by ssh
* mount LXC-Disk by enter
pct mount { LXC-ID }
you get the directory of the containers sysroot
* mount the new KVM-harddisk by using the following command:
modprobe nbd max_part=3
qemu-nbd -c /dev/nbd0 { KVM-Disk } // i.e.: vm-114-disk-1.qcow2
mount /dev/nbd0p2 { mount-point }
**** be careful: don’t use /mnt – it’s used by the host *** better use /media
* change to the sysroot-directory you got before
* copy the whole directory-structure to the mounted disk by using rync
rsync -a * { mount-point }
* unmount KVM-disk by enter
umount { mount point }
qemu-nbd -d /dev/nbd0
rmmod nbd
* unmount container-disk by
pct unmount { LXC-ID }
* now start the KVM again with a Live-ISO – should be equal to the LXC-OS
* mount the KVM-Disk i.e. /mnt
mount /dev/sda2 /mnt
mount /dev/sda1 /mnt/boot
* change sysroot by enter
mount -o bind /sys /mnt/sys
mount -o bind /dev /mnt/dev
mount -t proc /proc /mnt/proc
chroot /mnt
* install bootloader grub2
yum install grub2
* install a kernel
yum install kernel
* configure grub2-bootloader
grub2-install --force /dev/sdX1
grub2-mkconfig -o /boot/grub2/grub.cfg
* change the owner-id’s of /bin
cd /bin
chown root:root *
* exit chroot by
exit
* reboot in the KVM
