Conexión por escritorio remoto a servidor CentOS usando Protocolo de Windows (RDP)

Sacrilegio! Gritaran algunos…

En Linux es posible instalar un servidor RDP para usar el protocolo que se usa para conectarse remotamente normalmente a equipos Windows. El funcionamiento es a través de una pasarela RDP hacia un servidor VNC. Esto puede ser útil para aquellos administradores de Windows que no son muy dados a la administración por consola de equipos Linux (que es lo más recomendable en este tipo de ambientes)

Para esto se siguen unos sencillos pasos en CentOS 7 (pasos similares probablemente apliquen para otras distribuciones).

  1. Actualizar el sistema: Por favor, siempre, actualizar el sistema, siempre!

    yum update

  2. Instalar el repositorio EPEL

    yum -y install epel-release

  4. Configurar servicio, firewall y SELinux

    Una vez instalado se requiere habilitar el servicio para que inicie con el sistema, crear las reglas respectivas de firewall y tambien de SELinux

    systemctl start xrdp.service

    systemctl enable xrdp.service

    firewall-cmd –permanent –zone=public –add-port=3389/tcp

    firewall-cmd –reload

    chcon –type=bin_t /usr/sbin/xrdp

  5. Conectarse al servidor Linux por RDP

    Una vez configurado el servicio, solo se requiere usar el cliente de Windows para conectarse indicando la IP o el nombre del servidor (también funciona en clientes de RDP en Linux como Remmina):

    Inicio de cliente RDP

    Cliente RDP

    Certificado RDP

    Inicio sesion RDP

    Sesion RDP iniciada
