Q: Is there a way to connect to UltraVNC server and use built-in file transfer in Linux

Hrvoje TIs there a Linux VNC client that can use UltraVNC server's file transfer option? I tried my KDE default KRDC and Remmina, Java client TightVNC ... I tried to install UltraVNC client via wine also. No luck.

linux file-transfer ultravnc

Have you tried UltraVNC's Java viewer?
 
Hrvoje T
Hrvoje T
Yes. In Chrome and Firefox. In a tab, it shows PC's name and only empty white page with ultravnc web page link. Java plug-in problem? On server java http view enabled on port 5800.

According to Oracle, only Firefox 52 ESR supports Java. If you have Java installed, you can grab a pre-built copy of Firefox ESR from mozilla.org/en-US/firefox/organizations/all. Start Firefox ESR in a new profile and try the Java viewer in that browser.

I will try. For now no luck running that old Firefox on a system where I have Firefox Quantum already. I get an error when trying to run esr on 64bit Kubuntu with multiarch: x@probook6470b:~/Downloads/firefox$ ./firefox-bin XPCOMGlueLoad error for file /home/x/Downloads/firefox/libxul.so: libdbus-glib-1.so.2: cannot open shared object file: No such file or directory Couldn't load XPCOM. x@probook6470b:~/Downloads/firefox$ sudo ./run-mozilla.sh run-mozilla.sh: Cannot execute .

Try running the firefox binary instead. (Also, please don't append sudo)

If I do that, Firefox Quantum 58.0.2 from path is being executed.

Run the one in the ESR folder by navigating there and executing ./firefox -P. (Create a new profile for it too)

I did I got this error: x@probook6470b:~/Downloads/firefox$ ./firefox -P XPCOMGlueLoad error for file /home/x/Downloads/firefox/libxul.so: libdbus-glib-1.so.2: cannot open shared object file: No such file or directory Couldn't load XPCOM. Is it because I have a newer library?
ok, thanks for helping

ii libdbus-glib-1-2:amd64 0.108-2 amd64 simple interprocess messaging system (GLib-based shared library)

Is this the 64-bit version of Firefox ESR?
 
Hrvoje T
Hrvoje T
No. Should it be?
 
dsstorefile
dsstorefile
Your libdbus-glib package is for amd64, so a 64-bit version of Firefox ESR is probably needed
 
Hrvoje T
Hrvoje T
I thought because I have multiarch, this is not important.
ok, I will download 64-bit ver
ok, installed, started with a new profile. Firefox 52.6 is running. I went to 192.168.x.x:5800 and the same thing, white page with my remote pc name in tab label

There might be a default-java-plugin package in the Kubuntu repos, but that installs IcedTea and while it works on the Verify Java Version page from Oracle I'm not sure about its compatiblity in general
