Dell, why u no VPNC

Yo, we heard you liked remote desktops, so we put remote desktop into a remote desktop, now you can remote desktop while remote desktop.

I remember how IBM simply put VPNC interface in their Bladecenter. It was so nice. Unfortunately, vendors never want to be too nice to users, so their next release switched to a Java applet. Dell copied their approach for DRAC5. In theory, this should be future-proof, all hail WORA. In practice, it only worked with a specific version of Java, which was current when Dell shipped R905 ten years ago. You know, back then Windows XP was new and hot.

Fortunately, by a magic of KVM, libvirt, and Qemu, it's possible to create a virtual machine, install Fedora 10 on it, and then run Firefox with the stupid Java applet on it. Also, the Firefox and Java have to run in 32-bit mode.

When I did it for the first time, I ran Firefox through X11 redirection. That was quite inconvenient: I had to stop the Firefox running on the host desktop, because one cannot run 2 firefoxes painting to the same $DISPLAY. The reason that happens is, well, Mozilla Foundation is evil, basically. The remote Firefox finds the running Firefox through X11 properties and then some crapmagic happens and everything crashes and burns. So, it's much easier just to hook to the VM with Vinagre and run Firefox with DISPLAY=:0 in there.

Those old Fedoras were so nice, BTW. Funnily enough, that VM with 1 CPU and 1.5 GB starts quicker than the host laptop with the benefit of SystemD and its ability to run tasks in parallel. Of course, the handing of WiFi in Fedora 20+ is light years ahead of nm-applet in Fedora 10. There was some less noticeable progress elsewhere as well. But in the same time, the bloat was phenomenal.

UPDATE: Java does not work. Running the JNLP simply fails after downloading the applets, without any error messages. To set the plugin type of "native", ssh to DRAC, then "racadm config -g cfgRacTuning -o cfgRacTunePluginType 0". No kidding.
