ERR_SERVER_ALREADY_LISTEN on running rpos.js #39

Closed jov58 closed 6 years ago

jov58 commented 6 years ago

I'm trying to get this to work on a Raspberry Pi Zero W. But when I run the final command (sudo node rpos.js) I get this error. Does anybody have an idea how to resolve this?

Read IP address 192.168.1.130 from wlan0 Manufacturer : Raspberry Pi Model : Zero W HardwareId : SerialNumber : 000000002d926624 FirmwareVersion : 2.0.0 Starting camera settings webserver on http://192.168.1.130:8081/ Binding DeviceService to http://192.168.1.130:8081/onvif/device_service Binding MediaService to http://192.168.1.130:8081/onvif/media_service Uncaught Exception... : Error [ERR_SERVER_ALREADY_LISTEN]: Listen method has been called more than once without closing. at Server.listen (net.js:1446:11) at MediaService.SoapService.start (/home/pi/rpos/lib/SoapService.js:26:24) at Object.

usually that means you already have a Web Server listening on port 8081 already

You can change the port that RPOS listens on in the rposConfig.json file

That would be odd, because I used a brand new SD card, newly flashed with Raspbian Jessie. In that case, only the installation could have caused this? Speaking of installation, pls see my other post. Ah well, perhaps installed twice :), starting over again ...

The problem solved ?

jov58 commented 6 years ago

Nope. Stopped trying, busy doing other things.

Hi @jov58 and @Stuip I finally tracked down the cause of ERR_SERVER_ALREADY_LISTEN with the RPOS project. There were some network changes in Node JS version 9 and version 10 which broke RPOS.

I'd only ever used RPOS with Node v6 and Node v8 so I never saw the problem.

Anyway it has just been fixed in the RPOS source code.
