Hi all and Happy Easter! Hope the Easter brought you all lots of choccy s this morning (or will when he gets to you in your timezone LOL)!
After following the process outlined in this thread, I have finally managed to add a swap partition to my TP-Link Archer C7, and recreate my extroot config as it was before. Almost everything seems to be the same; nano
and samba4
are installed and working nicely, and my default terminal for root
is back to being bash
instead of ash
. Yippee!
The only problem is that SSH public key authentication no longer works. I can log in with the root
password if I enable the two relevant options under LuCI -> System -> Administration -> SSH Access, but trying to use the same public key as before fails, even after deleting it and re-adding it to LuCI -> System -> Administration -> SSH Keys. I also tried dropping and recreating the Dropbear instance, but to no avail. Boo!
Here's the output that I get from ssh -vvv root@ip
on my Windows machine:

So what's going on here? Most of those debug messages might as well be in Chinese for me; they look just as cryptic and confusing!
As always, MTIA!
