guac | A Git Repo Management CLI | Command Line Interface library

There is a configuration issue in the Java code. The GuacamoleConfiguration object should have the configuration of the target machine (windows) you are connecting to.

In your case, you are using the RDP protocol, so the hostname should have the address of the Windows machine you want to connect to. The username and password for the target windows machine are mandatory when RDP protocol is used. If you are using a domain user, you should also specify the domain parameter.

I believe the basis of your code is from the Guacamole example. This example explains how to connect to the VNC server, which does not require a username. In general, the basic configuration for connecting to windows should look like this:

The issue is that you are using euclidean distance for comparing strings. Consider using Levenshtein distance, or something similar, which is designed for strings. NLTK has a function called edit distance that can do this or you can implement it on your own.

I reinstalled with compiled versions xrdp 0.9.14 and xorgxrdp 0.2.14 - I had to do this anyway, because file sharing does not work between Guacamole and xrdp 0.9.12.

As a "side effect", the blocky/blurry appearance is gone now, too. Either it has been fixed with the newer version or my old installation was somehow faulty.

For guacamole version 1.0.0 and above, you will need to configure RemoteIpValve in your tomcat in order to see the source IP.

Firstly, make sure that your proxy send X-Forwarded-For header. For example (in nginx):

Your issue is caused by options.Conventions.AddPageRoute("/Identity/Account/Login", ""); which will redirect https://localhost to /Identity/Account/Login.

Try to comment out this line options.Conventions.AddPageRoute("/Identity/Account/Login", "");.

It's typically a good idea to look at the available documentation to see what properties are allowed. CSS isn't a programing language so values like null aren't supported the way you expect.

Instead, you often need to set the value back to "browsers default" instead of "none" by using the initial property.

So in your case background-attachment: initial would set that property back to the browser's default of scroll (meaning it moves with the page).

.contact-line has a height of 190px; If you set .contact-line: {display: none;} the gap goes away.

A couple of problems..

I think the reason for the ERR_CONNECTION_REFUSED is likely due to the VM instance falling short on resources and in order to keep the OS up, process manager shuts down some processes. SSH is one of those processes, and once you reboot the vm, resource will resume operation in full.

As per the "over-utilization" notification recommending g1-small (1 vCPU, 1.7 GB memory)", please note that, f1-micro is a shared-core micro machine type with 0.2 vCPU, 0.60 GB of memory, backed by a shared physical core and is only ideal for running smaller non-resource intensive applications..

Depending on your Tomcat configuration, also note that:

Connecting to a database is an intensive process.

Creating a Tomcat with Google Marketplace, the default VM setting is "VM instance: 1 vCPU + 3.75 GB memory (n1-standard-1) so upgrading to machine type: g1-small (1 vCPU, 1.7 GB memory) so should ideal in your case.

Why was g1 small machine type recommended. Please note that Compute Engine uses the same CPU utilization numbers reported on the Compute Engine dashboard to determine what recommendations to make. These numbers are based on the average utilization of your instances over 60-seconds intervals, so they do not capture short CPU usage spikes.

So, applications with short usage spikes might need to run on a larger machine type than the one recommended by Google, to accommodate these spikes"

In summary my suggestion would be to upgrade as recommended. Also note that, the rightsizing gives warnings when VM is underutilized or overutilized and in this case, it is recommending to increase your VM size due to overutilization and keep in mind that this is only a recommendation based on the available data.
