Apache Guacamole RDP connection not successful
Good evening,
I have installed Apache Guacamole 1.3.0 on a VM with Oracle Linux 8.2 for
testing purposes, using Apache Tomcat 8.5
While SSH session works fine, on the RDP session, it shows a screen with
another mouse pointer (one would think this is it) but it never lasts more
than 4 seconds, it disconnects. Been trying to work out what could be the
issue.
Sending the outputs of *guacd *and also *catalina* and *localhost_access_log
*and also logs , as the error messages regarding permission denied have me
baffled, whereas the file ownership and permissions seem fine in my
configuration.
*# tail -f /var/log/messages*

yes it was , and first checked if autotools packages were available, it was

It is now running, thank you very much Nick.

I'm asking that because I found that it's missing the configure script on
"guacamole-server-master" , the VM running the configuration doesn't have
internet access, only internal network access, which will be like the
client environment as well.

So it's safe to say I can just replace configure.ac file?

This is your issue, here - guacd is crashing/core-dumping for some unknown
reason. The output, here, is fairly hard to parse, as syslog just pukes it
into a single line. I think there are a couple of bugs that have been fixed
recently that might cover this. Could you check out the latest git master
code for guacamole-server and compile that and see if it still crashes?

To give proper context, the approach was to try to build guacamole-server
with rpm packages, from Oracle Linux repos, or EPEL repositories due to
compatibility, or build entirely from source.
Even knowing that guacamole-server has to be built from source, as it's
clear in the documentation, there's an existing guacd daemon rpm package ,
and also the libraries for client protocols, with the dependencies already
worked out.
guacd-1.3.0-1.el8.x86_64.rpm
libguac-1.3.0-1.el8.x86_64.rpm
libguac-client-rdp-1.3.0-1.el8.x86_64.rpm
libguac-client-ssh-1.3.0-1.el8.x86_64.rpm
libguac-client-telnet-1.3.0-1.el8.x86_64.rpm
libguac-devel-1.3.0-1.el8.x86_64.rpm
With that and the installation of Tomcat 8.5 , the access via SSH was
successful , however RDP failed even doing the ./configure script in
paralel to verify the requisites:
Library status:
freerdp2 ............ yes
pango ............... yes
libavcodec .......... yes
libavformat.......... yes
libavutil ........... yes
libssh2 ............. yes
libssl .............. yes
libswscale .......... yes
libtelnet ........... yes
libVNCServer ........ no
libvorbis ........... no
libpulse ............ no
libwebsockets ....... yes
libwebp ............. no
wsock32 ............. no
Protocol support:
Kubernetes .... yes
RDP ........... yes
SSH ........... yes
Telnet ........ yes
VNC ........... no
Services / tools:
guacd ...... yes
guacenc .... yes
guaclog .... yes
however this was the error
Mar 29 11:49:16 rdgtwlab guacd[233715]: Support for protocol "rdp" is not
installed
Which persisted even after updating freerdp and libwinpr packages
# rpm -Uvh libwinpr-2.0.0-46.rc4.el8_2.2.x86_64.rpm
libwinpr-devel-2.0.0-46.rc4.el8_2.2.x86_64.rpm
freerdp-libs-2.0.0-46.rc4.el8_2.2.x86_64.rpm
freerdp-devel-2.0.0-46.rc4.el8_2.2.x86_64.rpm
freerdp-2.0.0-46.rc4.el8_2.2.x86_64.rpm
So it was compiled from source and the guacd service derived from rpm
package was stoped and disabled to execute the binary built from source and
consequently restarting tomcat as well
root 113901 1 0 11:19 ? 00:00:00 /usr/local/sbin/guacd
-p /var/run/guacd.pid
root 113987 113901 0 11:20 ? 00:00:00 /usr/local/sbin/guacd
-p /var/run/guacd.pid
This solved the missing support issue, and still on the status point shown
on the beginning of this email.
The question is, what else is there that should be done or is missing from
the configuration?
Guacamole.properties file by itself could be just ommited with the defaults
already assumed, and tomcat configuration files are probably ok as the
webserver is running.
