Hi.
I know.. list is really only for fedora! But I was hoping I might
find someone who could point me in a direction to figure out what's
going on.
This is a digitalocean/ubuntu issue for setting up/testing SSH access.
Since this is a test, I'm more than willing to grant root access to
figure this out. I've created snapshots to recreate the
droplet/instance.
thanks
======
I have a test digitalocean droplet. It was setup for ssh access.
It more or less works. I have a few test users that I can ssh into
with no issue. I also created a test user with no ssh key, to test ssh
with password.
ssh testu@1.2.3.4
generates the "password" prompt to login, as expected.
I've tested this with a copy of "centos", as well as another ubuntu
20.04 system.
Both tests seem to work as expected.
I decided to do a copy of the initial DO droplet -- 161.35.5.174 and
to create another copy of this with the same dir/files/processes.
steps:
turn off "161.35.5.174"
Create a "snapshot" of the "161.35.5.174"
Use the "snapshot" to create another droplet with a diff IP. "161.35.5.x"
turn on 161.35.5.174
and use 161.35.5.x
so I now should have 2 valid droplets, with SSH access...
Now, at this point, I thought/assumed/hoped the user could simply
access the new droplet via SSH the same as the initial droplet.
I was sadly mistaken!
Or I have a subtle/massive user err.
my test users
root
sroot
crawl_user
*testu
Each of these have ssh keys/dirs on/in the droplets (except fo testu,
which is a simple user acct)
When I'm on the test centos, and I ssh into the 161.35.5.174, everything works..
ssh -v sroot@161.35.5.174 works as expected...
So, it appears the "161.35.5.174" initial droplet works as expected,
which implies the "ssh" server/daemon is working, and that the
/etc/ssh/sshd_config is configured/set
The idea is to allow for "root" access -- for the test
My goal for the overall test, is to allow
ssh access into the 161.35.5.174 droplet
via sshKey, as well as password.
and to do the same for the copied/created droplet
*******
THIS ISN'T WORKING!!!!!!!
when I'm on the centos and I test
ssh -vvv sroot@165.227.198.59
to allow sshKey, as well as "password" access via ssh
the results are:
sroot@ubuntu-s-1vcpu-2gb-nyc1-01:~$ ssh -vvv testu@165.227.198.59

it appears that the

the issue is why!
so.. anyone have any clues as to what I can test/check?
or what I've screwed up!!
thanks
by the way..
If I log into the "working/initial" droplet the --161.35.5.174
and I attempt to ssh/access the "copied" droplet --165.227.198.59
I get the same errs...
