The jupyter server operates on the loopback interface which has IP address 127.0.0.1 and IP name localhost. The cocoserver uses that same interface. Jupyter tries to get port 8888 and if that is busy it hunts for a nearby port that is not in use. The cocoserver uses an arbitrary system-assigned available port in the public range (above 1000).
I don't see what difference the choice of port makes to a user. It is not possible to guarantee that the same port will always be used, since ports are assigned on a first-come first-served basis. Consequently it is not possible to "bookmark" the address of either a jupyter server or a cocoserver. The port should be viewed as arbitrary and unpredictable. The address is always 127.0.0.1 in either case, by necessity. - Marc On Friday, April 26, 2024 at 4:05:12 PM UTC-5 Nils Bruin wrote: > On Friday 26 April 2024 at 12:29:14 UTC-7 marc....@gmail.com wrote: > > There are other issues with viewing local documentation files in a > browser.
