TroubleShooting

invalid login

  • 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

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
  • so installed libvncserver-dev and rebuild and reinstalled guacamole-server
  • and there it is, libguac-client-vnc.so
  • now the error message changed from "server error" to "unauthorized"
