I'm using Fedora 22 and the nmap provided netcat from the repos. I can open the page from a remote browser on the lan (as intended) but the connection refused occurs before connecting with a browser. When I open chrome, it states WebSocket has closed unexpectedly. Please reload the page.

Any suggestions on what to try? I have already attempted the nc -p\ncat edits to configure_webrx.py and the csdr/plugin.py.

Hi!

First of all, Merry Christmas!

Your problem seems to be related to the following output lines:

Using device 0: Generic RTL2832U OEM
usb_claim_interface error -6
Failed to open rtlsdr device #0.

It seems that your RTL-SDR dongle cannot be accessed.

OpenWebRX should work OK for you, unless the following command gives an error message:

rtl_sdr - >/dev/null
  • You may have a permission problem related to udev rules, especially if the following command runs OK:
sudo rtl_sdr - >/dev/null

Please follow the installation procedure for RTL-SDR from the following link: http://ha5kfu.sch.bme.hu/openwebrx-quick-setup

  • You may have to correctly blacklist the dvb_usb_rtl28xxu kernel module, especially if the following temporary fix helps:
sudo rmmod dvb_usb_rtl28xxu; rtl_sdr - >/dev/null

The instructions for this on the link above are not guaranteed to work on Fedora, so you will have to find out how to do it.

Merry Christmas to you as well. The errors may have been related to how I've been trying to get this to work. A fresh reboot, and I get this:

AttributeError: 'module' object has no attribute 'iq_server_port'

The error message indicates that iq_server_port = 4951 is missing from config_webrx.py, although it should be there.

function name given in argument 1 does not exist.

This indicates that you are running the dev branch of openwebrx, and not the dev branch of csdr.
Switch to the dev branch of csdr, then recompile it (make && sudo make install).

After switching to the dev branch of csdr openwebrx is now functioning
as expected. Thank you for your time and patience in helping me to get
this to run.
