Hello Everybody!

How i can do to change the default web port (80) of my DVSwitch Server with another port? Where i can find the program file to change this port?

Would changing the port have any repercussions, such as causing the RX Monitor button to malfunction?

I have three DVSwitch installations running on three different Linux computers.  Two of the three have the Dashboard running on the standard lighttpd port and the RX Monitor works fine.

I had to change the port on the third to something else since I already have a webserver occupying the standard one.  The RX Monitor on that one does not work.  It goes red, green, red, blue, etc. and no audio comes through.

Everything else behaves properly.

Thoughts?

On the two working DVSwitch installations, netstat -tnap shows the following line:

tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      1376/node

Which is, I assume, the RX Monitor doing its thing.

On the one where I switched lighttpd to port 8888, there is nothing listed with port 8080 anywhere.

Is that what you're looking for or do you need me to post the entire output? If the latter, then I'd need to (ahem) redact a few things in it for security reasons, HI HI.



On the one where I switched the lighttpd port, there is nothing with port 8080 listed.

Personally, I selected port 88 (after looking at the raw page and noticing that port 8080 was mentioned for RX Monitor) to avoid the obvious conflict there.

Also made sure nothing else was grabbing port 8080 on the machine.

Okay...problem (finally) solved.  Turns out that the problem was (probably) not related to changing the dashboard web port.  Documenting my experience so that others may benefit.

Steve, your suggestion to check for webproxy log started me on the trail: THERE WASN'T ONE! Which meant that the service wasn't running at all.

I then tried running the following command manually: sudo /usr/bin/node /opt/Web_Proxy/proxy.js 8080 2222 which generated a SyntaxError: "Unexpected token "Const { Exit }"

Much Googling told me earlier versions of node.js would do that.  Found out that, somehow, I had version (gasp) 4 installed for some reason! My other instances were running 8.10.0, so that had to be the culprit.  Much more Googling told me how to update it to the latest version (15.4.0 as of this writing):

First, install npm: sudo apt-get install npm
Then install n, a node version manager: sudo npm install -g n
Then install the latest version of node: sudo n latest
If the installer changed the path from what's specified in the webproxy service call, change it back with "PATH=$PATH"
Verify that node was truly updated with: node -v
Try running the service manually: sudo /usr/bin/node /opt/Web_Proxy/proxy.js 8080 2222
If you still get the same error, you might have to forcibly copy the newer binary to where the webproxy expects it to be: sudo cp /usr/local/n/versions/node/15.4.0/bin/node /usr/bin/node
Try running the service manually again.  If you get a "cannot find module "ws" " error, then do this: cd /opt/Web_Proxy/ and then install the ws module with sudo npm install ws
Try running the service manually again.  It should now run with no errors.  Control C out of it.  You're almost done.
Finally, start the service properly: sudo systemctl start webproxy.service

Voila: RX Monitor audio AT LAST!

Hi Steve and all, Is possible change port 8080? This port is to use for the other machine.
Thank you.
