can't get file transfer working. Help, please!

[quixote]

Thanks to all of you helping! It ought to be working based on what you're saying here and what I see elsewhere on the web. (I'm looking *everywhere*). I edited my user ssh_config, system-wide ssh-config and sshd_config in /etc/ssh/. Set "PasswordAuthentication yes" everywhere.

The error messages change a bit, but the message is always the same. Authentication failure or host unknown. My ssh is borked. Is there really no. other. way. to transfer files? 

If I ping the local IP of the pinephone, 10.66.0.82, it's right there. So the hardware is seeing it. There's just nothing that will let me connect.

One thing that occurred to me is that I'm still using stock mobian on the pinephone, so it's just got the 1234 password. Does ssh maybe block stupidly simple passwords??

I was briefly trying pinephone -> desktop. Since that didn't work, I'm back to desktop -> pinephone.

The thing that makes me crazy is I really don't want to troubleshoot ssh. I just need to transfer files. Single user environment. Zero security issues. This is reminding me of the Good Old Days when it was faster and easier to carry a floppy between buildings and transfer files using sneakernet than the miserable protocols available on ethernet. I'm going to take the sd card out and just put the files on it. But, man, I do hate to admit defeat like that.

All suggestions, if anyone has some, gratefully accepted!
