Reverse proxy & blank page after saving
Hi!, Anybody has seen the situation where Guacamole works normally to connect to different sessions, but saving session configuration leads to a blank page?. Settings are saved though, you just need to reload Home. The only catch is that I'm using a reverse proxy.

Not sure. It looks like this is a known issue either with the Maven javadoc plugin, with the javadoc tool, or both., and specifically with newer versions of the JDK: https://bugs.openjdk.java.net/browse/JDK-8212233 >From the above, it looks like a minor change to the pom.xml wherever the javadoc plugin is being configured may resolve things, informing javadoc that the code being documented is written for compatibility with Java 8. A similar issue was mentioned on the mailing list last month, with the user later noting the problem as solved by switching to JDK 8: https://lists.apache.org/thread.html/b82c6ed4c73af93a46e4efc1eb8b6a7d5c36cde382a12574e90873e7@%3Cuser.guacamole.apache.org%3E Perhaps there is more at work here than simply needing a specific JDK. - Mike
Re: Compile Fails, Does Not Find libjpeg-turbo
In general, on a platform using RPM packages, the convention is to separate the binaries of a library (libfoo) from the headers required to compile software against that library (libfoo-devel). An RPM that has already been built against a particular library can thus simply depend on the binary package for that library, and the user need not have a bunch of development headers installed that are not needed. Compiling software against the library would require both the binary and the development packages. Debian, Ubuntu, etc. follow similar conventions with "-dev" instead of "-devel". The fact that this worked for you before after installing only one package without the conventional "-devel" suffix suggests that the maintainers of that package did not follow that convention. Nothing within RPM inherently requires that the maintainer follow those conventions, of course, nor that they document that they didn't follow those conventions, nor that the package actually contain what is expected vs. a post-install script that runs "rm -rf /". Caveat emptor. - Mike On Wed, Jun 5, 2019 at 12:22 PM Zer0Cool wrote: > Sorry, correction... > > libjpeg-turbo-devel > > > > -- > Sent from: > http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/ > > - > To unsubscribe, e-mail: user-unsubscr...@guacamole.apache.org > For additional commands, e-mail: user-h...@guacamole.apache.org > >

The two parts of the stack which could contain a problem resulting in a mishandled event are: 1) The browser-side keyboard event handling within JavaScript 2) If keyboard events within the browser are handled correctly, the handling of received events within protocol-specific event handling (libguac-client-rdp, etc.) RDP keyboard event translation is complex, but if you're seeing this same behavior regardless of underlying protocol, and specifically within Firefox, that suggests something may be behaving differently on the JavaScript side. We have a test page for just the keyboard event handling which can be used to verify whether things are not behaving as expected in the client. Try testing against that with the affected browser and see whether you see the same issue: http://guacamole.apache.org/pub/tests/guac/keyboard-test.html ... > Jun 7 13:58:11 inf-fw3 guacd[18791]: Internal RDP client disconnected > Jun 7 13:58:11 inf-fw3 guacd[14495]: Connection > "$ae4363ce-1671-40f0-8734-ce45d6af39ad" removed. > Jun 7 13:58:11 inf-fw3 kernel: guacd[18797]: segfault at 7fd7ea22001c ip > 7fd802aafb8b sp 7fd801ccece0 error 4 in > libguac-client-rdp.so.0.0.0[7fd802a98000+2c000] > > > Note the segfault. > > What can I try? > Is it worth a JIRA report? Segfaults within the RDP support tend to be due to older builds of the guac*.so plugins for FreeRDP hanging around from older builds of guacamole-server, so I wouldn't recommend opening a new JIRA issue at this point. First verify that there is nothing hanging around from older builds (or from distribution packages, or third-party packages). If there is any chance that the FreeRDP libraries may have been upgraded since you last built things, I'd recommend rebuilding as FreeRDP releases are not generally API- nor ABI-compatible, and this could also cause a segfault without there being an issue within Guacamole. If you can confirm the above, and the segfault is reproducible, a backtrace from gdb would be the next step to determine what is happening. I don't believe this is related to the keyboard behavior you're seeing. - Mike

In particular, the tunnel is designed to rely on the server to dictate which remote desktop the user is connecting to and how, such that the administrator always controls what can and cannot be accessed by users of the system. It is possible to provide users with the ability to connect to completely arbitrary hosts, either through an extension, something like the recently-added "quickconnnect" extension, or through writing your own webapp, but that middle part that enforces server-side control (the tunnel) is critical. I wouldn't recommend trying to work around that intended control due to the security implications of allowing such an unrestricted level of access. - Mike
Comparison of Spice-html5 and Guacamole
Is it possible to use Guacamole's js-Files in a same manner as https://gitlab.freedesktop.org/spice/spice-html5 ? Spice is for virtual machines terminals and so can't be shared between multiple user but I like it, it's very easy: " 1. Start the spice server 2. Start websockify; my command line looks like this: ./websockify 5959 localhost:5900 3. Fire up spice.html, set host + port + password, and click start " .

Firefox client and Guacamole
Hi, In a previous message I mentioned a problem I was seeing with several Firefox versions. Whenever I try to connect to either a telnet service or RDP server via Guacamole, I sometimes get an odd behavior as if the user (me) were sending out ENTER keystrokes (I sent a screenshot). This is usually fixed by logging out and back in again. However, it can randomly occur again until I log out once again. This is what I get in my logs when it happens.
