Nick,
the distribution is RHEL 7.4:
# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.4 (Maipo)
I'm using openjdk:
# java -version
openjdk version "1.8.0_144"
OpenJDK Runtime Environment (build 1.8.0_144-b01)
OpenJDK 64-Bit Server VM (build 25.144-b01, mixed mode)
SELinux was enabled but I've now completely disabled it and rebooted
the
machine:
# getenforce
Disabled
This change has no effect on the behavior.
I looked a bit in the Guacamole code and found the place where it tries
to read the guacamole.properties file
(guacamole-
ext/src/main/java/org/apache/guacamole/environment/LocalEnvironment.jav
a). I've added debug statements to understand what happens:
> > >
// Read properties
properties = new Properties();
try {
InputStream stream = null;
// If not a directory, load from classpath
if (!guacHome.isDirectory())
{
stream =
LocalEnvironment.class.getResourceAsStream("/guacamole.properties");
}
// Otherwise, try to load from file
else {
File propertiesFile = new
File(guacHome,"guacamole.properties");
logger.info("FW: The file name is:"+propertiesFile.getAbsolutePath());
if (propertiesFile.exists())
{
stream = new FileInputStream(propertiesFile);
logger.info("FW: The file exists:"+propertiesFile.getName()+"\n");
}
}
<<<<
The output I get in /var/log/messages is:
INFO o.a.g.environment.LocalEnvironment - FW: The file name
is:/etc/guacamole/guacamole.properties
INFO o.a.g.environment.LocalEnvironment - No guacamole.properties file
found within GUACAMOLE_HOME or the classpath. Using defaults.
So even though the file /etc/guacamole/guacamole.properties exists, the
propertiesFile.exists() call returns false for some reason. And
probably
the same is true for the user-mapping.xml file. So I wonder whether
this
might be a problem in openjdk. Is guacamole usually working better with
a proprietary Java version?
