socket.error...but changing port didn't help, nor did reboot

[noequus]

I installed and played with SIP for a while (I like it) but now I cannot get it to run, with this error (full terminal text below):

socket.error: No socket could be created -- (('::192.168.1.15', 8666, 0, 0): [Errno 99] Cannot assign requested address)

As you can see I changed the port (tried several). Also tried stopping the service and status with systemctl:

pi@192.168.1.15:~/SIP$ sudo service sip stop
Failed to stop sip.service: Unit sip.service not loaded.

pi@192.168.1.15:~/SIP$ systemctl status sip
Unit sip.service could not be found.

Thanks for any thoughts!
Gary

pi@192.168.1.15:~/SIP$ sudo python sip.py

Hi Gary,
Usually the "No socket could be created" error indicates that something else is using the port.

Have you tried rebooting the Pi?

The "Unit sip.service could not be found" error sounds like the service is not enabled.
did you follow the instructions on the SIP wiki under
Installation and Set UP > Starting the program automatically > [url=https://github.com/Dan-in-CA/SIP/wiki/Installation#the-recommended-method][/url]The recommended method :

1. Copy the script file to /etc/systemd/system. Run the command:
   sudo cp SIP/sip.service /etc/systemd/system/
2. Enable sip service:
   sudo systemctl enable sip.service
3. Reboot the Pi:
   sudo reboo
4. t
   

Or if you want to run SIP under Python3 use sip3.service with the above instructions.

Then try:

Code:

systemctl status sip (or sip3)

to stop, use

Code:

systemctl stop sip

to start use

Code:

systemctl start sip

How did you change the port number if SIP was not running?

It can be done by editing SIP/data/sd.json and changing the line "htp": 80,
Be sure to keep the comma after the port number.

Usually the "No socket could be created" error indicates that something else is using the port.

"Cannot assign requested address" could also be that not only the port is configured but also the IP address. When the IP of the PI changes e.g. by DHCP than there is trouble. Unless you have multiple interfaces you would configure the ip as 0.0.0.0

Hi Dan:



Now upgrading from buster to bullseye and having exactly the same problem as I did two years ago (in this thread: OSError: No socket could be created). It appears regardless of what port I use. Unfortunately, no idea how it was fixed!




In this case I just now enabled SIP as a service hoping that would help but it didn't solve the problem (it is active and running). Prior to that I could successfully run SIP from the command line but not as a @reboot line in crontab (that's how it was in buster). Here's the crontab line I used with the result below. 




@reboot sudo python3 /home/pi/SIP/sip.py  >> /home/pi/SIP-OUT.txt 2>&1




Not sure how to run SIP from the command line when running as a service...can't do that now; suggestions welcome.

Be sure you have on Options->System->HTTP IP addr no ip address entered. Only :: is enough.
You can also check the config file:  SIP/data/sd.json  

In there it should be: 

Code:

"htip": "::",

That was it--thank you so much--really appreciate it! All seems good now (at least with SIP...).

Best wishes,
