I would like to know how to take remote desktop control from my ubuntu machine to another Ubuntu machine. Totally I have 80 plus Ubuntu users and if I have remote desktop it will be easy for us to fix the issues.

SSH server

You can install an ssh server for example openssh-server in the Ubuntu systems that you want to access remotely. Then you can connect via ssh to run programs remotely and via sftp or rsync to transfer files.

See these links,

help.ubuntu.com/lts/serverguide/openssh-server.html

help.ubuntu.com/community/SSH

If you use key authentication, you need not use password to log in, which makes things faster and easier. Then you can also disable password authentication, which makes things safer.

Example

Shellscripts

You can use a shellscript similar to this to transfer files,

send-data-to-computer-x:

#!/bin/bash

if [ $# -ne 1 ]
then
  echo "Usage: $0 <user@ip-adress>"
  exit
fi


echo "$0 $1 sending data via rsync"


rsync -Hav directory-to-transfer "$1":/home/${1%@*}

You can use a shellscript similar to this to do things at the remote computer, in this example check with md5sum that the transfer was successful,

do-things-at-computer-x:

#!/bin/bash

if [ $# -ne 1 ]
then
  echo "Usage: $0 <user@ip-adress>"
  exit
fi


echo "$0 $1 running commands via ssh"


ssh "$1" "cd directory-to-transfer;grep -v ' .md5sum.txt$' md5sum.txt | md5sum -c"

These shellscripts can be run from a master shellscript with user@ip-adress specified for every target computer in order to make things convenient.

Use Vino, or deploy another VNC server to the users: https://help.ubuntu.com/community/VNC/Servers

And you are going to need to start it up on the target machines: Enable remote VNC from the commandline?

Then you can use any VNC client from your location to connect to the remote machine.
