    How to take remote desktop of Windows from Linux

    In Linux we have a utility rdesktop which is used to take remote to any Windows machine. let us see how it works and the iptable rules to allow or reject the same.

    You need to install rdesktop package for this purpose. For RHEL machine you can use the below command

    To check for existing package
    # rpm -qa | grep rdesktop
    To install a new package
    # yum -y install rdesktop
    Once the package is installed run the below command from the GUI console of your Linux box
    NOTE: rdesktop will only work from GUI console and not from CLI or putty

    Syntax
    # rdesktop (machine_name_to_connect)
    # rdesktop 192.168.1.7

    And this should do the magic.

    In case you get any graphical console related error follow the below link
    Xlib: No protocol specified

    Iptables rules for rdesktop


    To allow a particular subnet to which your machine can connect
    # iptables -I OUTPUT -d 192.168.1.0/24 -p tcp --dport 3289 -j ACCEPT
    To block a subnet to which your machine can connect
    # iptables -I OUTPUT -d 192.168.1.0/24 -p tcp --dport 3289 -j REJECT
