Pro2 OS6 WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

Hi, Pro2, OS6, Ubuntu Not sure why (I may have disabled /re-enabled SSH?) but I received this warning today: david@ubuntu-140402C:~$ ssh root@192.168.1.8 @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@...

In the UI you must have had private home shares enabled. When you login via SMB for the first time as a user the home share for it is created.

If you have a dynamic I.P. it's also possible it's got an I.P. you've previously SSH'd into to a different device.

This issue can be encountered with any device you want to SSH into.

I would typically use the latter of those two commands you mentioned.

This warning is more important when logging in to remote sites. It's a security precaution to provide warning of a possible man-in-the-middle attack.

Thanks mgdm.

ssh-keygen -R <ip.of.nas>
My password resulted in:
Permission denied, please try again.

nut the password still works in the browser.

I tried using 'password' as a long shot with the same result.

Any ideas please?

Best regards,
David

  Try changing your password in the web admin interface of the NAS.

    Thanks for helping, mgdm.
    
    OK, password accepted using ssh. Then ....
    david@ubuntu-140402C:~$ ssh root@<ip>
    david@192.168.1.8's password:
    Creating directory '/home/david'.
    Not sure why it did this?
    
    Looking at home:
    root@NASPro:/# cd home
    root@NASPro:/home# ls -al
    total 16
    drwxr-xr-x 1 admin admin 10 Sep 25 13:15 .
    drwxr-xr-x 1 root root 198 Sep 25 13:34 ..
    drwx------ 1 david users 0 Oct 1 13:13 david
    OK but rmdir david won't work as I can see I don't have full permission.
    
    drwx------ 1 david users 0 Oct 1 13:13 david
    root@NASPro:/home# rmdir david
    rmdir: failed to remove `david': Operation not permitted
    
    I am confused why directory david just created is poputated:
    root@NASPro:/home# cd david
    root@NASPro:/home/david# ls -al
    total 0
    drwx------ 1 david users 0 Oct 1 13:13 .
    drwxr-xr-x 1 admin admin 10 Sep 25 13:15 ..
    
    Can I get rid of home/david that was just created in and if so how? 'david' is my username, group 'users'
    
    Many thanks,
    David
