I started by spinning up an entirely new vm running Ubuntu Server 20.04.03 to test with. I used the latest Ubuntu 20.04.03 ISO and after a quick Google I found the following guide and used it to install Guacamole 1.3.0. I also ran an apt-get update/install before and after installing guac and there’s nothing outstanding currently. For right now I am just using the user-mapping.xml file with a md5 hashed password for authentication.
Guacamole on Ubuntu 20.04 – Somik's Home<https://somik.org/guacamole-on-ubuntu-20-04/> The only thing I added during the Ubuntu install was OpenSSH. Other than that it was a bare install. I have since found a few other older guides that mention potential issues with the freerdp2 package that comes in the official Ubuntu 20.04 repo. I don’t think that’s my particular issue but I’ll probably give it a try and replace the freerdp2 package with the remmina repository version and then remake the Guac install. Failing that I found another guide here: Install and Use Guacamole Remote Desktop on Ubuntu 20.04 | ComputingForGeeks<https://computingforgeeks.com/install-and-use-guacamole-on-ubuntu/> so I’ll try that one next as it is a bit more in-depth. Regarding rsyslog, what I read said omfile shouldn’t need to be loaded since it’s built-in. But here is a copy of my rsyslog.conf file: # /etc/rsyslog.conf configuration file for rsyslog # # For more information install rsyslog-doc and see # /usr/share/doc/rsyslog-doc/html/configuration/index.html # # Default logging rules can be found in /etc/rsyslog.d/50-default.conf ################# #### MODULES #### ################# module(load="imuxsock") # provides support for local system logging #module(load="immark") # provides --MARK-- message capability # provides UDP syslog reception #module(load="imudp") #input(type="imudp" port="514") # provides TCP syslog reception #module(load="imtcp") #input(type="imtcp" port="514") # provides kernel logging support and enable non-kernel klog messages module(load="imklog" permitnonkernelfacility="on") ########################### #### GLOBAL DIRECTIVES #### ########################### # # Use traditional timestamp format. # To enable high precision timestamps, comment out the following line. # $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat # Filter duplicated messages $RepeatedMsgReduction on # # Set the default permissions for all log files. # $FileOwner syslog $FileGroup adm $FileCreateMode 0640 $DirCreateMode 0755 $Umask 0022 $PrivDropToUser syslog $PrivDropToGroup syslog # # Where to place spool and state files # $WorkDirectory /var/spool/rsyslog # # Include all config files in /etc/rsyslog.d/ # $IncludeConfig /etc/rsyslog.d/*.conf Also, for reference here is the user-mapping.xml file I am using. <user-mapping> <!-- Per-user authentication and config information --> <!-- A user using md5 to hash the password guacadmin user and its md5 hashed password below is used to login to Guacamole Web UI--> <authorize username="guacadmin" password="1094b670a163ecae02f82317f51f5abc" encoding="md5"> <!-- First authorized Remote connection --> <connection name="Ubuntu Desktop"> <protocol>ssh</protocol> <param name="hostname">10.0.0.20</param> <param name="port">22</param> </connection> <!-- Second authorized remote connection --> <connection name="Windows 10"> <protocol>rdp</protocol> <param name="hostname">windows10</param> <param name="port">3389</param> <param name="username">user</param> <param name="ignore-cert">true</param> </connection> </authorize> </user-mapping> Also, here is the output of the Catalina log: 02-Dec-2021 18:53:50.726 INFO [main] org.apache.catalina.core.StandardService.startInternal Starting service [Catalina] 02-Dec-2021 18:53:50.732 INFO [main] org.apache.catalina.core.StandardEngine.startInternal Starting Servlet engine: [Apache Tomcat/9.0.31 (Ubuntu)] 02-Dec-2021 18:53:50.752 INFO [main] org.apache.catalina.startup.HostConfig.deployDescriptor Deploying deployment descriptor [/etc/tomcat9/Catalina/localhost/host-manager.xml] 02-Dec-2021 18:53:50.787 WARNING [main] org.apache.catalina.startup.HostConfig.deployDescriptor The path attribute with value [/host-manager] in deployment descriptor [/etc/tomcat9/Catalina/localhost/host-manager.xml] has been ignored 02-Dec-2021 18:53:53.381 INFO [main] org.apache.jasper.servlet.TldScanner.scanJars At least one JAR was scanned for TLDs yet contained no TLDs.

From: Ivanmarcus<mailto:ivanmar...@yahoo.com.INVALID> Sent: Thursday, December 2, 2021 2:36 PM To: user@guacamole.apache.org<mailto:user@guacamole.apache.org> Subject: Re: Invalid Login Vincent, We'll probably need more information than this to be able to assist you. For instance: The version of Guacamole you've installed. The authentication method you chose (are you using database auth?) How you installed it (the steps you used, did you use someone's script?) Also, it looks as if you might want to address the rsyslog issue. Strange it's coming up from a fresh Ubuntu install, but perhaps try update/upgrade first. If that doesn't work you may need to look at rsyslog.conf and compare it against https://www.rsyslog.com/doc/v8-stable/configuration/modules/omfile.html Finally, when fault-finding I try to look for common causes to an issue. In your case it raises a question as to why you're experiencing logging issues as well as the Guacamole auth problem. You mentioned this was a fresh install - I wonder what that means? Was this a completely new HDD, new install of 20.04, or perhaps did you install/upgrade over an existing version of Ubuntu?
