Thank you very much. This is my first time working with virtual adapters and I confused myself with the addresses.
By the way, in Ubuntu, rtsp does not work in vlc, so I had to install the Flatpack version.
Now everything works.

Password correct. I can enter through adb and login ssh both local and outer addresses:

adb.exe shell
* daemon not running; starting now at tcp:5037
* daemon started successfully
# ssh root@localhost
root@localhost's password:
# pwd
/root
# exit
Connection to localhost closed.
# ssh [email protected] ...

I downloaded and flashed the firmware\buildroot\Luckfox_Pico_Mini_B_Image from the Google disk under Windows using Soc Toolkit.
I assigned the 172.32.0.93 address to connection.

usb0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 172.32.0.93 netmask 255.255.0.0 broadcast 172.32.255.255 ...
