If you dont have anything listening on port 8080 on localhost, that must return a Connection refused error.

I ran this from a command prompt; I assume that's correct, and that I didn't need to be in a particular directory? Does it create a log somewhere? When I run it, nothing happens - or more accurately, I run it and then a new prompt appears immediately, with no error messages or other output. I don't entirely understand your explanation here, so I'm not sure what to make of this result.

Just for the heck of it, I did try turning off the Windows FW completely, as well as entirely disabling my AV and AS (at which point Windows certainly believed I had no FW or AV), but this made no difference.

If there is no output that means something on your computer accepted a connection on port 8080, which is why the calibre server is not starting, since it thinks something is listening on that port.

Grab the Sysinternals (now owned by M$) TCPView.exe

It will show all the 'connections' in use and the endpoints, maybe you will see port 8080 in use

This would make more sense if I hadn't tried about 15-20 different port numbers, from 8080 up to 45000. Is something on my computer accepting a connection on all of these?

No, because actually, I just tried the code you gave me with port 45000, and I got the error "No connection could be made because the target machine actively refused it." Did the same with port 8787, and got the same "actively refused it" message. And yet I'm still getting "Port 8787 [or 45000] not free on 0.0.0.0" when I try to start the server on those ports.

So something else must be going on, right?

Tried this; no sign of 8080, or indeed anything anywhere near 8000-9000, anywhere on the list of connections/ports in use.

I am just beyond baffled. Not that I'm anywhere near an expert in this stuff, but still.

The code I posted is the exact code that is used by the server to check for a busy port. I'm afraid I'm out of ideas at this point.

Actually, here's one more thing to do run the following command and post the output:

calibre-debug -c "import socket; print socket.getaddrinfo('127.0.0.1', 8080, socket.AF_UNSPEC, socket.SOCK_STREAM)"

When I ran with 8080, output was:

[(2, 1, 0, '', ('127.0.0.1'), 8080))]

(I am not sure how to capture from a cmd prompt window, so I'm just retyping it; the '' is two single quotes).

Same result running with 8787, or with any other port number I tried.

Right-click the Dos Logo in the upper left corner.

I knew about pasting, but not copying - thanks!

[kovidgoyal]

That output is correct, I give up.

[jesscat]

I give up too. And after rebooting everything - all computers on network, router, modem - I did manage to get it running fine on one of my laptops, using 8787 (8080 still not working). Not ideal, because I don't usually keep calibre open on that one, and I do keep it open on another machine almost all the time, so metadata.db can't sync regularly between them. But it'll do well enough - I'm just glad to have gotten it working at all!

Thanks for all your help!
