It’s been a while since I experimented with this, so some fiddling with my instructions may be necessary. Enabling HTTPS

chapulina, that actually has me pointed in the right direction. I'll update this ticket once I get it all nailed down.

I'll have to look into that idea further. My preference though would be to modify/update the existing webserver to support SSL.

It may be possible (can we make gzweb aware of it's DNS name?), but get's very complicated in our situation, referencing a lot of client's cloud servers. We don't really want the hassle of trying to proxy all their stuff and would prefer to be able to tell them how to enable SSL themselves for their application.

We run an integration of GZWeb in the cloud, embedded via iFrame into our main webserver. With Google making a big push to everyone to run HTTPS only, we find we are restricted because gzweb is only HTTP, and we get blocked iframes due to mixed content.

Is there any way to run the viewer via HTTPS? I'm completely inexperienced with nodejs...

We run a custom roslaunch that starts up gazebo with some custom models that appear to all be .gazebo and .xacro files. These models utilize ros modules for laser vision and vehicle control.

I can't seem to figure out how to get these models functioning in gzweb. I've tried adding the path to the gazebo/xacro files as a gazebo_model_path. I've tried converting the xacro to sdf, writing my own .config, and adding it to gzweb assets folder. If I do this, however, when I run the thumbnail generator is complains that rosinit has to be run (I'm guessing that's related to the modules used in the model).

Please help.

I'm also wondering if it's an issue with gazebo being version 2 in this particular case...I don't recall this issue on our other gazebo 6 installations.

Since there are LOTS of folders in here and the error occurs on a large number of them, I'm looking for a better solution than hand-modifying every single model.sdf and model.config...

When running deploy -t, the first folder's thumbnails are generated, and it hangs almost immediately on the second folder with the following, and never comes back (I have to CTRL-C):

Warning [parser.cc:340] Converting a deprecated source[/home/sitl/gzweb/tools/../http/client/assets/arm_part/model.sdf].
Warning [Converter.cc:59]   Version[1.6] to Version[1.4]
  Please use the gzsdf tool to update your SDF files.
    $ gzsdf convert [sdf_file]
Error [Converter.cc:127] Unable to convert from SDF version 1.6 to 1.4
Msg Waiting for master
Msg Connected to gazebo master @ http://127.0.0.1:11345
Msg Publicized address: 10.2.222.41
Error [Node.cc:90] No namespace found

I have tried running the gzsdf tool as it suggests and still get:

Error [Converter.cc:127] Unable to convert from SDF version 1.6 to 1.4

This is preventing me from being able to successfully install gzweb (at least usefully).

I really don't want to do a full gazebo install on our production web server as it hosts a bunch of other stuff. I may not understand how gzweb/nodejs are working, but I was hoping to point a nodejs installation on the webserver to the bridge on the simulation server. It doesn't appear to be elementary to split up the installation like this.

chapulina's comment was in the right direction, but not quite there. The files were missing, even though I had included them in the deploy. I copied them into the assets folder and it fixed it.

Hello,

I've installed gzweb, and configured the GAZEBO_MODEL_PATH variable to include my custom models prior to running the deploy script.

I'm running a script from the PX4 folks to produce a quadcopter running inside a gazebo simulation. It shows up just fine in gzclient, but I can't get the graphic for the model to show in GZWeb. The object is present - I can select it in the object selector, it's just like it has no graphics/textures.

It DOES show up in my gzweb http/assets folder. Ideas? It's a basic iris quadcopter model...

Also, when trying to install nodejs (on Ubuntu Precise) I get an error that nodejs conflicts with npm? Weird. That's using the setup file provided at http://gazebosim.org/tutorials?tut=gzweb_install&cat=gzweb#Runninggzserver,gzwebserver,andWebGLclient

I'd like to integrate a GZWeb server on an existing web server, but don't want the simulation load on that machine. I'm guessing it's possible to run the simulation on one server and the web portion on another, but am not sure which packages would go where. Looks like node.js on the webserver and gzbridge on the simulation server, does this sound right? Where would I configure the ports/connections for gazebo/node.js? Prerequisites for each package?

If we generate a log file using gzserver, can it be replayed in gzweb?

No, VPN is not an option for us.

I'm trying to run gzserver on a cloud instance running behind a firewall, and access the simulation with gzclient from outside the firewall.

To make a long story short, I've discovered that while I can set GAZEBO_IP and GAZEBO_MASTER_URI to handle the intial connection, gzserver sends back to gzclient it's IP and some random port(s) for retrieval of additional data.

It's the random additional ports that I'm having trouble with, being behind a firewall. Any idea where in the code I can go to specify a specific port instead of this random mess?
