When using IPA for managing user authentication you can come across this issue of SSH dropping just after a password change. It can be resolved by changing options in /etc/ssh/sshd_config. You need to be ROOT to make this change and restart SSHD service to take effect.

Showing Line numbers in Vi /Vim Text editor would be very helpful when it comes to troubleshooting code errors in a file. This works on almost all Linux/UNIX distributions. Once you are in the edit file mode, Type while in edit mode ":set nu" OR ":set number" and then it will show you the Line numbers and then you can jump to a specific line by typing ":number" or any line number you require.

If you can't spend thousands for a static IP, Try out this script which sends out an email alert whenever Public IP address changes. In a situation where you need a VPN solution without spending thousands on a static IP no matter if you are a HOME user or a Small Business owner, all you need to have is a RasberryPi and a decent Small Business VPN Router. For this article I used a Cisco RV110w VPN Router.

Reducing LVM disk size is possible using lvreduce on the fly without a reboot. Make sure that data is backed up for the disk to be resized so that FREE space can be reused. LVM (Logical Volume Management) is very efficient when it comes to mounting/partitioning disks in Linux. You need to be ROOT to carry out this process.
