[Samba] Access to sockets denied in Termux

[Mike Yates]

Is there a way to start smbd when ports < 1024 are unavailable?
It seems that qemu does it, because the -nic smb=<path> provides a working
smbd instance available to smbmount, if not win9x. So what smb.conf options
does qemu use?
smbd -D crashes in Termux, as shown below.

No, I don't have root in my Android. I understand that prevents access to
ports below 1024 but I find that Linux clients can mount Termux
qemu-started Samba shares nevertheless.
I need to prevent smbd crashing for want of low sockets and wonder if win9x
can mount without them.
