Ben's notes

The packaged version in EPEL is 0.8.4. A fairly (a few years) old version. So this page uses the most recent files from: Apache Guacamole.

• Check the release notes for addtional actions, like upgrading the database schema.

• Download the source code and SHA sums from: http://guacamole.incubator.apache.org/releases/
• Verify the source code:

  sha256sum -c *.sha
  guacamole-client-0.9.11-incubating.tar.gz: OK
  guacamole-server-0.9.11-incubating.tar.gz: OK

• Compile the server:

  tar zxf guacamole-server-0.9.11-incubating.tar.gz
  cd guacamole-server-0.9.11-incubating/
  
  autoreconf -fi
  # No SystemD services yet...
  ./configure --with-init-dir=/etc/init.d --prefix=/opt/guacamole
  
  make
  make install # as root

• Stop guacd:

  service guacd stop

• Edit /etc/init.d/guacd:

  change: pidfile="/var/run/$prog.pid"
  to:     pidfile="/opt/guacamole/run/$prog.pid"
  
  change: getpid > /dev/null || $exec -p "$pidfile"
  to:     getpid > /dev/null || sudo -u guacuser -- $exec -p "$pidfile"

• Start guacd:

  service guacd restart

• Install the client:

  tar -xzf guacamole-client-0.9.11-incubating.tar.gz
  cd guacamole-client-0.9.11-incubating
  
  mvn package

• Deploy:

  cd guacamole-client-0.9.11-incubating
  
  rm /var/lib/tomcat/webapps/guacamole.war
  cp guacamole/target/guacamole-0.9.11-incubating.war /var/lib/tomcat/webapps/guacamole.war
  
  #Check logging
  journalctl -u tomcat

• Guacamole supports TFA via Duo
• Download the Duo extention via http://guacamole.incubator.apache.org/releases/.
• Verify the archive:

  sha256sum -c *.sha
  guacamole-auth-duo-0.9.11-incubating.tar.gz: OK

• Create the GUACAMOLE_HOME/extensions directory, if it does not already exist. We have a symlink from /etc/guacamole to /usr/share/tomcat/.guacamole.

  cd /etc/guacamole
  mkdir extensions

• Copy guacamole-auth-duo-0.9.11-incubating.jar within GUACAMOLE_HOME/extensions.

  tar zxvf guacamole-auth-duo-0.9.11-incubating.tar.gz
  cp guacamole-auth-duo-0.9.11-incubating/guacamole-auth-duo-0.9.11-incubating.jar /etc/guacamole/extensions
  chown tomcat. /etc/guacamole/extensions/

• Restart Tomcat:

  systemctl restart tomcat

• Follow the documentation at https://guacamole.incubator.apache.org/doc/gug/duo-auth.html

• This was based on the 0.9.10 version.

    ssl_certificate_key "/etc/pki/nginx/private/server.key";
    ssl_session_cache shared:SSL:1m;
    ssl_session_timeout  10m;
    ssl_ciphers HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers on;
  
    # Load configuration files for the default server block.

  systemctl start nginx

• Create directory and file: /usr/share/tomcat/.guacamole/user-mapping.xml. See example in /root/guacamole-client-0.9.10-incubating/guacamole/doc/example/user-mapping.xml. Example:

  <?xml version="1.0" encoding="UTF-8"?>
  
  <user-mapping>
  
   <authorize username="user"
              password="md5pass"
              encoding="md5">
  
     <connection name="example.com">
       <protocol>ssh</protocol>
       <param name="hostname">example.com</param>
       <param name="font-name">Liberation Mono</param>
     </connection>
  
     <connection name="ssh.example.com (SSH)">
       <protocol>ssh</protocol>
       <param name="hostname">ssh.example.com</param>
     </connection>
  
     <connection name="vnc.example.com (VNC)">
       <protocol>vnc</protocol>
       <param name="hostname">vnc.example.com</param>
       <param name="port">5901</param>
       <param name="password">vncpassword</param>
     </connection>
  
     <connection name="win10.example.com (RDP)">
       <protocol>rdp</protocol>
       <param name="hostname">win10.example.com</param>
       <param name="port">3389</param>
     </connection>

  chmod 600 /usr/share/tomcat/.guacamole/user-mapping.xml

• Create a symlink to /etc for ease of use:

  ln -s  /usr/share/tomcat/.guacamole /etc/guacamole</code
    * Restart tomcat:<code>systemctl restart tomcat
