O SSH (security shell) terminal de acesso seguro, programa no qual é incrivel para administração de servidores remotamente, possui também um recurso para executar comandos gráficos pelo terminal.

O commando a seguir permite executar aplicações graficas  do ambiente X por ssh.

ssh -X uruario@nome_da_máquina_ou_ip


~# ssh -X usuario@servidor
~# gedit &
~#[1] 12363

Claro que para isso funcionar o arquivo “/etc/ssh/ssh_config” deve ser configurado. Procure pela opção “X11Fowarding” e aplique o valor “yes” ao mesmo.

(Obs.)Talvez a maioria dos parametros deste arquivo deva estar comentado.

O arquivo Original se parece com isto:

# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.

# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.

# Site-wide defaults for some commonly used options. For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.
