2 IP Adresses, but only one wanted

[ottischwenk]

My Calibre has 2 IP addresses for the wireless connection - how can I determine that only one of them is active?
Above all, I don't know where the second address comes from

Where are you seeing this? Calibre uses 2 PORTS:1 id the content server the other is wireless device connection.

BTW What OS and Calibre version.

[ottischwenk]

Windows 11 Pro 23H2 (Build 22631.2428)
Calibre 6.29

Are you running a VPN on the computer calibre is running on?

[theducks]

There is a Tweak for what Ethernet port to listen on (intent was for computers with more than 1 Network) Do you have both WiFi and Wired connected. This may solve which to ONLY use

No, but Wifi and installed PureVPN (not running)

calibre listens on all IP addresses by default so you should be fine. As for whwere the 2 come from that will depend on the network setup on your computer. calibre simply reports whatever it finds.

OK, what, when I want only one (defined) to be used by Calibre?

Use the option in the Sharing over the net->Advanced->The interface on which to listen for connections

I cannot use the server

calibre, version 6.29.0
ERROR: Failed to start Content server: Could not start the Content server. Error:

No socket could be created -- (('10.0.0.8', 8080): [WinError 10013] Der Zugriff auf einen Socket war aufgrund der Zugriffsrechte des Sockets unzulässig)

And it doesnt help at wireless connection

[kovidgoyal]

Then just leave it as 0.0.0.0 you dont need to specify an interface.

i would need the wireless connection only at 10.0.0.8

When you open a command prompt and type ipconfig /all and hit enter, what does it show for the network adapters and their associated addresses?

Is another application already using the port & socket? Something like netstat -aon | findstr 9099 from a CLI session can help with this (substiture the port you are using with calibre for the 9099. You can use the PID at the end of the line to locate the other program if it shows.

It is Hyper-V Virtual Ethernet Adapter and even if I disable it, it appears in Calibre and is enabled again after a restart
