Open GUI in Remote Machine

Method 1: Use telnet

Assume the IP address of the local host is 128.100.2.16 and the IP address of the remote host is 17.200.10.5. Depending on the network you are on, you may also be able to use the computer names (domain names) instead of the IP addresses.

Step 1. On the local host

Type the following at the command line:

% xhost + 17.200.10.5

Step 2. Log on to the remote host

% telnet 17.200.10.5

Step 3. On the remote host (through the telnet connection)

Instruct the remote host to display windows on the local host by typing:

% setenv DISPLAY 128.100.2.16:0.0

Method 2: Use ssh

Connect to remote machine using ssh
ssh -X -C user@MyIp

this method is slow, though.

Method 3: Use nomachine or vncserver

Setup Nomachine Connection in Ubuntu

1. disable firewall:
  sudo fw disable

2. check ssh:
  ssh localhost
if get an error:
 ssh: connect to host localhost port 22: Connection refused

then install the following:
 sudo apt-get install openssh-server
