Guacamole 0.3.0 on Ubuntu 10.04

Guacamole is a program to tunnel a Linux desktop to a browser.

Sometimes in your Linux life, you need to control your servers in the internet with a graphical user interface. The problem is when you are behind a corporate firewall blocking ssh requests to the public internet. Typical corporate firewalls only allow proxified client access to port 80 and 443 in the public internet. The solution is to use a browser to display a Linux desktop. The solution is not, however, to use VNC for a web browser, as it will be blocked by corporate firewalls.

Here is what I did to configure Guacamole on 2011-06-25 using a rackspace server with Ubuntu 10.04 x64:

• install some dependencies

apt-get install tomcat6 libvncserver0

• download this package

• unpack it

tar xvzf guacamole-0.3.0-ubuntu-10.04-x86-64.tar.gz

• install the contained software

cd guacamole-0.3.0-ubuntu-10.04-x86-64
dpkg -i *.deb

• put the software to the right place

ln -s /var/lib/guacamole/guacamole.war /var/lib/tomcat6/webapps
ln -s /etc/guacamole/guacamole.properties /var/lib/tomcat6/common/classes

• edit /etc/guacamole/user-mapping.xml

<user-mapping>
   <authorize username="user" password="password">
      <protocol>vnc</protocol>
         <param name="hostname">localhost</param>
         <param name="port">5901</param>
         <param name="password">passwort</param>
    </authorize>
</user-mapping>

This will allow you to log in as user named user with the password password.

• install a vnc server

apt-get install tightvncserver

• start the vnc server

vncserver
