Unable to get RDP working, after installing freerdp and binary packages
Hello party people..I am really about to tear my eyes out dealing with this issue. I am working on deploying a guacamole setup to my AWS account, however, after leaving instances running accidentally on a few occasions, I figure it would be better to get the configuration down on a local network before deploying on the cloud. So. I have two Xubuntu 18.03 VMs running in virtual box. One of them has xrdp installed and the other guacamole server installed. During the build process for guacamole server, I installed most of the optional dependencies, including libfreerdp-dev and binary packages. When I ran the .configure script, it informed me all protocols were enabled except telnet. After deploying the war file to tomcat, however, guacamole kicks back a message stating the connection has timed out. Now here is the super annoying part.I know this is not an issue with rdp because I installed remmina (multi protocol remote desktop tool, for any unfamiliar with ubuntu packages) and was able to initiate an rdp connection from the guacamole machine with zero issue. Same thing when I connect from my host machine to the xrdp host, zero issue. I set the basic parameters in the user-mapping.xml file: hostname, port, username, password. I wont be back to my main machine for a few hours so I cannot post log details at the moment. I can provide those shortly. Any pointers in the right direction would be swell.thanks : -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/

Guacamole view connection URLs
Hello, I have another question for you guys. I am trying to integrate my application with guacamole, providing a way for my customer to easily spin up training environments for their students. I am creating a dashboard for instructors to view all of their current registrations. Once a registration has been verified, spin up an EC2 instance, and allow the students to connect via guacamole. Ideally, I would like to insert a link into the instructor dashboard with the URL to launch the guacamole viewer for said instance, so the instructor does not need to keep multiple tabs open. I'm assuming the link to open any given connection is not set in the database and is generated on demand? So if I wanted to grab that URL, I would need a guac API call? I would appreciate if someone could tell me a way to grab those links without going through the API, as my app is written in python. Thanks -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/
"Communications link failure" Exception being thrown.... Dear god help
I have pasted the relevant contents of the catalina.out file to the link below, as in the past some people have complained about code formatting. When I began testing my application, I was actually running a mysql server on an ec2 instance instead of running against an RDS instance. So my database currently is residing in an Aurora serverless cluster. I haven't experienced this exception before. That is the only major differences between my earlier test configurations. I am really stuck here, I have no idea where to begin troubleshooting this issue. Checked the syslog, no relevant messages logged there. I get the classic "blank screen" situation that I have posted about in the past. Any help on this would be greatly appreciated. --Zach http://dpaste.com/0GJ63JE -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/
Re: "Communications link failure" Exception being thrown.... Dear god help
I wish you had a little more faith in me than that. Yes I made sure I was able to establish a connection with the cluster by using the mysql client with the same credentials I provided to guacamole.

JDBC connection string

Re: "Communications link failure" Exception being thrown.... Dear god help
Alright guys. I have an update to this story. I put together a small java class for the purpose of testing JDBC functionality on the EC2 instance in question. I was able to execute a query successfully against my database using the same MySQL jar that resides in my /etc/guacamole/lib folder. So I am fairly confident now there is an issue with my configuration, the RDS cluster is not the issue. I tried to do the bare minimum config according to the docs.

Re: "Error connecting to RDP server" Linux machine
I was able to get the instances to connect via guacamole by changing the xrdp.ini file authentication to rdp instead of negotiate. Only problem now is that the connection is stable for a few minutes before crapping the bed. It will stay stuck in that loop of working, then disconnecting, until I logout.

Re: "Error connecting to RDP server" Linux machine
Found the issue. Wasn't setting the requisite nginx proxy rules *face palm*. Cannot believe I overlooked something so basic. Had you not brought it up, I never would have thought to check that. You saved me from bashing my brains dude. Seriously. Thank you, thank you, thank you. HTTPS is now working after inserting those rules.

Re: "Error connecting to RDP server" Linux machine
Bizarre. I was finallysomehowable to get a stable connection via guacacmole, for about twenty minutes. As soon as I added another connection, my original connection timed out and it went in a loop where one session would be disconnected and the other would connect.

Re: "Error connecting to RDP server" Linux machine
Sorry if I didn't explain the situation more clearly. The connections are not pointed at the same machine, they are pointed at different machines (ec2 instances).

Re: "Error connecting to RDP server" Linux machine
Spoke too soon. I'm back to the same problem of when I'm logged in with one user, as soon as the next user logs in (to a totally different machine), guacamole kicks the first user.

Re: "Error connecting to RDP server" Linux machine
Not seeing anything specifically related to HTTPS/fallback. Since you mentioned that, however, I went ahead and disabled HTTPS on my nginx proxy and that seems like it may be the culprit. I have a connection going right now and it has been solid for the past five minutes. What settings do I need to look at regarding HTTPS? -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/

Hey guys, I'm really confused as to why I am receiving the aforementioned error when trying to initiate an RDP connection.
