in thread [OT] A New Everything ?

You'd have saved yourself a lot of time and effort if you'd read the DigitalOcean tutorials on this subject.

Maybe. I wouldn't say the time was wasted when I needed to read up so much with unix again, along with a new vendor to me, DigitalOcean. Also, I just had to make half a dozen big mistakes on my own time, but success was achieved 12 days after my first droplet formed. I may have twisted my arm off patting my own back when I used vi correctly, but ALL THREE TIMES, I locked myself out. Somewhere along the line, I found the button for "send me a new root password."

Furthermore, I wouldn't call the process as linear as digital ocean might make it seem with their hyperlinks. set-up-ssh-keys has many pointers, but I don't think it has anything about chown'ing and chmod'ing .ssh and authorized_keys. Many hyperlinks don't make the search more specific.

The above gives this line of code, which I could never get to work:

cat ~/.ssh/id_rsa.pub | ssh username@remote_host "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"

Similarly, I couldn't get this to work, and not for lack of trying:

ssh-copy-id -i id_rsa.pub wilma@143.110.153.42

What did work was doing it from scratch. From my laptop:

scp id_rsa.pub root@164.90.158.33::/home/fred/.ssh

Log-in as root one last time:

root@fourth:/home/fred# cd .ssh/ root@fourth:/home/fred/.ssh# ls -al total 12 drwx------ 2 fred fred 4096 Sep 26 23:38 . drwxr-xr-x 3 fred fred 4096 Sep 26 23:36 .. -rw-r--r-- 1 root root 419 Sep 26 23:38 id_rsa.pub root@fourth:/home/fred/.ssh# cat id_rsa.pub > authorized_keys root@fourth:/home/fred/.ssh# chown fred:fred authorized_keys root@fourth:/home/fred/.ssh# chmod 600 authorized_keys -rw------- 1 fred fred 419 Sep 26 23:43 authorized_keys -rw-r--r-- 1 root root 419 Sep 26 23:38 id_rsa.pub root@fourth:/home/fred/.ssh#

And finally, log-in as fred:

fred@fourth:~/.ssh$ ls -al total 16 drwx------ 2 fred fred 4096 Sep 26 23:43 . drwxr-xr-x 4 fred fred 4096 Sep 26 23:46 .. -rw------- 1 fred fred 419 Sep 26 23:43 authorized_keys -rw-r--r-- 1 root root 419 Sep 26 23:38 id_rsa.pub fred@fourth:~/.ssh$ .. fred@fourth:~$ ls -al total 32 drwxr-xr-x 4 fred fred 4096 Sep 26 23:46 . drwxr-xr-x 3 root root 4096 Sep 26 20:57 .. -rw-r--r-- 1 fred fred 925 Sep 26 23:39 .bash_aliases -rw-r--r-- 1 fred fred 220 Sep 26 20:57 .bash_logout -rw-r--r-- 1 fred fred 3771 Sep 26 20:57 .bashrc drwx------ 2 fred fred 4096 Sep 26 23:46 .cache -rw-r--r-- 1 fred fred 0 Sep 26 20:57 .cloud-locale-test.skip -rw-r--r-- 1 fred fred 807 Sep 26 20:57 .profile drwx------ 2 fred fred 4096 Sep 26 23:43 .ssh fred@fourth:~$
