Ok, I'm on Opera Browser. Trying this on MS Edge could solve the problem?
I don't know... go ahead and try it. opera, edge, chrome, firefox...
if you can't get the quotes sorted out, this may never work. And it isn't worth much more effort at this point -- you could have done 10 resets and re-configures in the time we've spent here.
Ok, thanks for your time.
Are there any additional steps afterwards?
start from scratch -- reset your router to defaults. try to ssh in. it should work. update the password. try again, it should still work. Setup your DNS and any other basic settings (do not restore). test at every major step -- if it breaks, you'll know what did it.
Then, if you are trying to do more advanced things, read up on them and ask specific questions (in a new thread per major topic) if you are stuck.
Are you trying to run OpenSSH Server (sshd) at the same time as dropbear? You should remove OpenSSH and get Dropbear, which is the default SSH server, to work.
We already did this step, as you can see on my previous posts...
As a quick note:
PuTTY is refusing even to connect to Dropbear after removal of OpenSSH. I remember that was my motivation of getting a connection terminal result anyway.
I would try to remove Dropbear first, then install OpenSSH, to further troubleshoot the situation and possibly mark the Dropbear Service the culprit.
I've got a terminal screen to try a login, but I could not get access again...
Instead of resetting the router, I setup a SSH public key and voila, it worked!!
Now, how can I fix the shadow error?
Thank you...
Edit: Your commands above worked like a charm. there is no shadow entry anymore...
