Guacamole 0.8.3

Trying on Ubuntu 10.04
- download the guacamole webapp from http://sourceforge.net/projects/guacamole/files/current/binary/
- deploy it
# mv guacamole-0.8.3.war /var/lib/tomcat6/webapps/
- surf to http://localhost:8080/guacamole-0.8.3. A folder /var/lib/tomcat6/webapps/guacamole-0.8.3 will be created with some content. We will need that later.
- download guacamole-server and guacamole-client from http://sourceforge.net/projects/guacamole/files/current/source/
- unpack it
- build the server:
# ./configure && make -j8 && make install # guacd guacd: error while loading shared libraries: libguac.so.5: cannot open shared object file: No such file or directory # cp ./src/libguac/.libs/libguac.so.5.0.0 /usr/lib/libguac.so # guacd guacd[11581]: INFO: Guacamole proxy daemon (guacd) version 0.8.3 guacd[11581]: INFO: Successfully bound socket to host ::1, port 4822 guacd[11581]: INFO: Exiting and passing control to PID 11582
- create a folder /etc/guacamole
mkdir /etc/guacamole
- create a file /etc/guacamole/guacamole.properties with the content
# Hostname and port of guacamole proxy guacd-hostname: localhost guacd-port: 4822 # Location to read extra .jar's from lib-directory: /var/lib/tomcat6/webapps/guacamole-0.8.3/WEB-INF/classes # Authentication provider class auth-provider: net.sourceforge.guacamole.net.basic.BasicFileAuthenticationProvider # Properties used by BasicFileAuthenticationProvider basic-user-mapping: /etc/guacamole/user-mapping.xml
- create a file /etc/guacamole/user-mapping.xml with the content
<user-mapping>
<authorize username="user" password="password">
<protocol>vnc</protocol>
<param name="hostname">localhost</param>
<param name="port">5901</param>
<param name="password">password</param>
</authorize>
</user-mapping>
- find out your tomcat's user directory:
# cat /etc/passwd|grep tomcat tomcat6:x:113:116::/usr/share/tomcat6:/bin/false
- in this case it is /usr/share/tomcat6
- create a folder .guacamole in your tomcat's user directory:
mkdir /usr/share/tomcat6/.guacamole
- link guacamole.properties into your tomcat's user directories' guacamole folder
ln -s /etc/guacamole/guacamole.properties /usr/share/tomcat6/.guacamole
- now the problem is that tomcat does not know where to find the Authentication class:
/var/lib/tomcat6/webapps/guacamole/WEB-INF/classes/net/sourceforge/guacamole/net/basic/BasicFileAuthenticationProvider.class
is not in /etc/guacamole/guacamole.properties
- so add it
- cat /etc/passwd gives me a line
tomcat6:x:113:116::/usr/share/tomcat6:/bin/false
ll /usr/share/tomcat6/.guacamole/ total 8 drwxr-xr-x 2 root root 4096 Nov 26 07:58 ./ drwxr-xr-x 6 root root 4096 Nov 26 07:57 ../ lrwxrwxrwx 1 root root 35 Nov 26 07:58 guacamole.properties -> /etc/guacamole/guacamole.properties
- works now. So the thing is:
- take care that it is called guacamole and not guacamole-0.8.3 (sure?)
- make sure the classpath in /etc/guacamole/guacamole.properties is correct, e.g.
# Location to read extra .jar's from lib-directory: /var/lib/tomcat6/webapps/guacamole/WEB-INF/classes
- start a vnc server, as password set password (the vnc password given in user-mappings.xml)
vncserver
- point your browser to http://localhost:8080/guacamole-0.8.3
- log in as user, password password (the user given in user-mappings.xml)
- next steps: SSL
- next steps: proxypass
Server error
- now I got a server error so I straced guacd:
strace -p 15332
and saw
[pid 20344] open("/usr/lib/x86_64-linux-gnu/libguac-client-vnc.so", O_RDONLY) = -1 ENOENT (No such file or directory)
so the problem is that libguac-client-vnc.so is missing.
- downloaded java version 1.7.45 and compiled guacamole-client using mvn. But there was no *.so* file in it
