Hello,
I seen guacamole for the first time at another company, and I I was amazed of how beautiful this product is. I have been struggling to get it to work on my personal lab for quite a while, I tried different guides, but never got guacamole to work past the "HTTP Status 404 - Not Found" when accessing http://192.168.159.138:8080/guacamole Can you please examine my case and guide my on the direction to get it to work, I have included the terminal history for how I installed it, nit planning to use ldap, or mysql initially, just the basic config on the user-mappings.xml, here is the log: sudo apt-get update sudo apt-get upgrade 101 apt-get install guacamole-tomcat (installs tons of packages) Downloaded guacamole client 1.0.0.war and renamed it to guacamole.war 119 sudo cp guacamole.war /var/lib/tomcat8/webapps 121 sudo cp guacamole.war /usr/share/tomcat8 122 sudo cp guacamole.war /usr/share/tomcat8/webapps sudo cp guacamole.war /var/lib/guacamole/guacamole.war 132 /etc/init.d/guacd start 133 /etc/init.d/tomcat8 restart 139 sudo mkdir /usr/share/tomcat8/.guacamole 141 sudo cp -s /etc/guacamole/guacamole.properties /usr/share/tomcat8/.guacamole 142 sudo service tomcat8 restart 143 sudo service guacd restart 146 service tomcat8 status 147 service guacd status 161 sudo systemctl daemon-reload 162 sudo service tomcat restart && sudo service guacd restart 163 sudo service tomcat8 restart && sudo service guacd restart also added "guacamole.home=/etc/guacamole" yo /var/lib/tomcat8/conf/catalina.properties and authorized local account login to user-mappings.xml Those are logs located at /var/log/tomcat8 192.168.17.1 -
