A better VNC

I’ve been using VNCViewer from RealVNC under Linux to remote connect to an older machine running windows. Two reasons, I don’t need yet another screen on my desk, and I need windows to adequately test and use the MySQL GUI products, in particular MySQL Workbench.

I never realised there was a better way, particularly over a local network, a command called rdesktop which is capable of natively speaking Remote Desktop Protocol (RDP).

$ su -
$ yum install rdesktop

This did only give me version 1.3.1. The current version 1.4.1 available from the rdesktop Website does provide greater commands including the syntax I use.

su -
cd /src
wget http://optusnet.dl.sourceforge.net/sourceforge/rdesktop/rdesktop-1.4.1.tar.gz
tar xvfz rdesktop-1.4.1.tar.gz
cd rdesktop-1.4.1
./configure
make
make install

Example Usage

$ rdesktop -u <username> -p <password> -K -N -z -a 16 -x b -P <target IP address>
</target>

Some additional common options include -d and -f for fullscreen.

I haven’t reviewed the security implications but considering I’m only running in my own internal network, it’s not a major priority.
