Can't print in RDP sessions
Hi, I am using Guacamole 1.0.0 in Debian 9 with Tomcat 8, database authentication with self-sgned SSL certificate. After following the installation documentation <https://guacamole.apache.org/doc/gug/installing-guacamole.html> I documented my initial 0.9.14 installation steps here <https://wiki.debian.org/Guacamole>. I then recently used this script <https://raw.githubusercontent.com/MysticRyuujin/guac-install/master/guac-upgrade.sh> to update, while working around a small bug <https://github.com/MysticRyuujin/guac-install/issues/77>. VNC, SSH and RDP remote sessions are used daily without problems. I can't seem to get a prompt to save the PDF file generated when printing in RDP sessions. I initially had to symlink all files in /usr/local/lib/freerdp to /usr/lib/x86_64-linux-gnu/freerdp, for example (see this bug report <https://github.com/oznu/docker-guacamole/issues/3>): ln -s /usr/local/lib/freerdp/guacdr-client.so /usr/lib/x86_64-linux-gnu/freerdp/guacdr-client.so After reboot guacdr started normally: Feb 27 14:35:19 guacamole guacd[14998]: guacsnd connected. Feb 27 14:35:19 guacamole guacd[14998]: guacdr connected. When connected, a new printer "Guacamole PDF printer" (as I named it) showed up. When I start printing there is no error, only a message on my local browser notifications "Waiting for guacamole.domain.lan...:" and nothing happens. Ghostscript is installed, in /var/syslog I see: Feb 27 14:44:51 guacamole guacd[23876]: Device 0 (Imprimante Guacamole PDF) connected successfully Feb 27 14:45:07 guacamole guacd[23876]: Print job created Feb 27 14:45:07 guacamole guacd[23876]: Created PDF filter process PID=24158 Feb 27 14:45:07 guacamole guacd[24158]: Running gs And a gs process is running continuously: PID TTY STAT TIME COMMAND 24158 ? S 0:06 gs -q -dNOPAUSE -dBATCH -dSAFER -dPARANOIDSAFER -sDEVICE=pdfwrite -sOutputFile=- -c .setpdfwrite -sstdout=/dev/null -f - But nothing happens... If I close the session then a file dialog to save appears, the resulting file is very small (255 bytes) and of course corrupted but it has PDF headers. I tested this using both Firefox ESR and 65, Chrome and Chromium, from Debian 9 and WIndows 7 Pro desktops with the same results. Any ideas or suggestions on how to troubleshoot further ? Thanks in advance. F. -- Fabián Rodríguez http://fsf.magicfab.ca/

Search for "Session recording" at this page: https://guacamole.apache.org/doc/gug/configuring-guacamole.html#connection-configuration I'd suggest first upgrading to the latest version of Guacamole, otherwise if you run into problems it makes it harder to help you.

I am not sure how to indicate this otherwise, but it's not intuitive. I tested this with 2 sysadmins and they both highlighted this - it's not a huge issue after our initial setup is done, for sure.

New user, Debian HowTo, some suggestions
Hello, Many thanks for this software, it's proving very useful and I am happy I was able to replace other similar proprietary software in a particular situation I was dealing with. I'd like to suggest some improvements, I preferred no to use the bug tracker yet for this. Here is my short list: * In Settings > Users > $USER > Permissions, I'd like to be able to set two extra permissions: o access sessions History tab o access Active Sessions tab * When using the filter to find connections, I'd like to see which Group they belong to (if any). Sometimes I have connections with the same name in different groups, the current filtering results don't show group membership * Timezone for each user should be the same as the server's by default (or have an option to use the same as the server's) * When clicking on a group checkbox, the selection should also include all members of the group, either checking or unchecking all boxes. I have some large groups (40+ connections) and it would be faster to be able to include/exclude all connections in any given group. * Selecting a connection in a group is not enough to give access, the group also needs to be checked which is not obvious (perhaps it should be automatic) My recent setup of Guacamole on a Debian server wasn't easy as the packages are outdated and some manual configuration was required. I've shared my notes for Debian server installation here if anyone is interested: https://wiki.debian.org/Guacamole Any comments for improvement are most welcome. The goal was to use as much as Debian provides in terms of official packages and long term use (and support). I took the opportunity to file a few bug reports in Debian.
