Rsync with a non-standard ssh port

While doing some work on migrating accounts to a new server, I needed to use rsync over ssh. The ssh daemon on the remote server runs on a non-standard port, and all the port related options to rsync only change settings if you’re running the rsync-daemon.

After some searching, the man page of rsync  offered a solution:

rsync -avz -e "ssh -p $portNumber" /localpath user@remoteip:/remotepath

 

Rsync (Remote Sync): 10 Practical Examples of Rsync Command in Linux

Rsync (Remote Sync) is a most commonly used command for copying and synchronizing files and directories remotely as well as locally in Linux/Unix systems. With the help of rsync command you can copy and synchronize your data remotely and locally across directories, across disks and networks, perform data backups and mirroring between two Linux machines.

This article explains 10 basic and advanced usage of the rsync command to transfer your files remotely and locally in Linux based machines. You don’t need to be root user to run rsync command.

Some advantages and features of Rsync command
  1. It efficiently copies and sync files to or from a remote system.
  2. Supports copying links, devices, owners, groups and permissions.
  3. It’s faster than scp (Secure Copy) because rsync uses remote-update protocol which allows to transfer just the differences between two sets of files. First time, it copies the whole content of a file or a directory from source to destination but from next time, it copies only the changed blocks and bytes to the destination.
  4. Rsync consumes less bandwidth as it uses compression and decompression method while sending and receiving data both ends.

Linux : How do you display each sub-directory size in a list format via the command line

If you want to get a list of the directories and their sizes in a list format then siply use the below:

du -h
Provides this but it displays all of the sub-folders.
du -h --max-depth=1

Alternative

If --max-depth=1 is a bit too long for your taste, you can also try using:

du -h -s *

This uses -s (--summarize) and will only print the size of the folder itself by default. By passing all elements in the current working directory (*), it produces similar output as --max-depth=1 would:

The difference is subtle. The former approach will display the total size of the current working directory and the total size of all folders that are contained in it… but only up to a depth of 1.

Add an Additional Disk Drive to Your Linux Server or VM and and partitioning it

Prerequisite: This tutorial covers adding a new disk drive to your linux computer. First it is assumed that the hard drive was physically added to your system.

IDE based systems, can support two drives on each ribbon cable. The cable is attached to either the Primary or Secondary IDE controller. A “jumper” is pressed onto two pins (thus connecting the two pins) on the drive to define the drive as a “Master” or a “Slave” drive. Each cable can support one master and one slave drive. Typically new desktop systems have one hard drive connected as a Master on the Primary controller and one CD-Rom on the second cable configured as a master.

How to change the hostname in Linux

If you are new to linux you probably will wonder how to change the hostname of your computer or server. (A hostname is the unique name by which a network attached device is known on a network.) If you enter the wrong hostname during the installation, and you need to change the hostname, here is the solution:-

 

  • Edit file /etc/sysconfig/network using your favourite editor. In my case is nano. So i’ll enter  nano /etc/sysconfig/network
  • Look for HOSTNAME=xxxxxx
  • Change the xxxx to the name you wish to set for your computer. (ex: HOSTNAME=wiredgorilla.com)
  • Save the file and restart the xinetd service. (ex: type service xinetd restart in your shell)
  • Done! You have just changed your hostname in Linux platform
