Overview

Guacamole Server

Edit Package guacamole-server
http://guac-dev.org/

Guacamole is an HTML5 web application that provides access to desktop environments using remote desktop protocols such as VNC or RDP. A centralized server acts as a tunnel and proxy, allowing access to multiple desktops through a web browser. No plugins are needed: the client requires nothing more than a web browser supporting HTML5 and AJAX.

This is the server-part.

Hi,

currently the server doesn't work. When I try to open a rdp or vnc connection I get an error saying the protocol is not supported. Seems there are some wrong / missing dependencies.

Regards, Martin

Okay. Do you have some log-entries for me?

Or can you stop the service and start it manually? Like: guacd -l 4822 -b 127.0.0.1 -L debug -f or guacd -l 4822 -b 127.0.0.1 -L trace -f

I've noticed the same thing - note that building from source on the same host worked, so it seems your spec file might be faulty - though it seems that when you install the server component it installs all dependencies, but then cant find them... logs below:

ssh: guacd -l 4822 -b 127.0.0.1 -L trace -f guacd[987]: INFO: Guacamole proxy daemon (guacd) version 1.1.0 started guacd[987]: DEBUG: Successfully bound socket to host 127.0.0.1, port 4822 guacd[987]: INFO: Listening on host 127.0.0.1, port 4822 guacd[987]: INFO: Creating new client for protocol "ssh" guacd[987]: INFO: Connection ID is "$da373294-df88-42ec-80be-c0837ccf09a1" guacd[989]: WARNING: Support for protocol "ssh" is not installed guacd[989]: DEBUG: Requesting termination of client... guacd[989]: DEBUG: Client terminated successfully. guacd[987]: INFO: Connection "$da373294-df88-42ec-80be-c0837ccf09a1" removed.

Hope this helps - Patrick

Patrick, could you please share the spec file which worked for you?

Eric, in the ecsos:server spec file, there are a few references to the directory "%{_libdir}/freerdp2", which should contain files libguac-common-svc-client.so and libguacai-client.so. The files are missing from the built rpm file.

Cheers!

Hello gianza, can you please test if it is fixed now? Should version 1.2.0-lp152.2.1. 2.1 is important. And please report if it is fixed.

Hi Eric, I've updated the package and the /usr/lib64/freerdp2/ folder is now available, with the 2 libs. Unfortunately, the RDP protocol is still not working. The log is not giving clues other than saying the protocol is not installed:

 journalctl for guacamole-server.service with log_level = debug:

Hello!, just tested with guacamole-server-1.3.0-lp152.4.1.x86_64, I got the same "support for protocol xxx is not installed" for SSH & VNC.

No missing libraries evident checking the client plugins with lld

Ciro Iriarte's avatar
Ciro Iriarte (ciriarte) -

I went with building by hand to (hopefully) close my deployment quicker, I hit the same issue of "protocol XXX is not installed".

In the end I fixed it modifying my service definition adding under [Service]:

Environment="LD_LIBRARY_PATH=/opt/guacamole/lib64"

There are other ways to do this, like adding an entry in /etc/ld.so.conf.d/guacamole.conf, but given it's only for the service it shouldn't be an issue.

Probably it's something similar with the package, libraries might not be in the dynamic linker path

Can you please test it again with version >= lp152.5.1?

Just installed lp153.7.2, I receive the same error:

guacd[25981]: WARNING: Support for protocol "ssh" is not installed

I see the configuration is there:

remote01:~ # cat /etc/ld.so.conf.d/guacamole.conf /usr/lib64 /usr/lib64/freerdp2

remote01:~ # rpm -qf /etc/ld.so.conf.d/guacamole.conf guacamole-server-1.3.0-lp153.7.2.x86_64

but it doesn't work :/

Sorry for the mess, but formatting things here is impossible

Hi,

Can you please add a build for Tumbleweed aarch64? I have tried compiling myself but I am getting deprecated errors for freerdp.

Thank you.

Eric Schirra's avatar
Eric Schirra (ecsos) -

Done.

Thank you. I've managed to build it locally earlier on using your spec file. Would you mind adding the client as well? Kind regards.

Eric Schirra's avatar
Eric Schirra (ecsos) -

Also done.

Eric, it appears the build is broken. GuacD reports the same issue as above.

SSH and VNC are not installed. Could you please advise how this can be fixed?

Thank you.

For anyone looking for the 'support for protocol xxx is not installed' issue - I just discovered that my issue was that the packages install libguac-client-xxx.so.0 while the dynamic loader is trying to load libguac-client-xxx.so which means it fails.

Eric Schirra's avatar
Eric Schirra (ecsos) -

Okay. Thanks for the info. Normally the *.so packages are in the devel package. So also with me.

Could you test if the application works if you also install the devel package?

zypper in guacamole-server-devel

If it works, then you can run it again with

zypper rm -u guacamole-server-devel

to uninstall it.

Please give me an info, then I move the *.so into the "normal" package.

Hello!, I would like to give it another try. I'm getting:

Problem: 1: nothing provides 'libavcodec.so.61(LIBAVCODEC_61.3_SUSE)(64bit)' needed by the to be installed guacamole-server-1.5.5-lp156.1.4.x86_64

is there a external repository required?
