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
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
15:61:82:a9:b6:15:72:fe:08:4e:9f:3d:1a:88:bc:b3.
Please contact your system administrator.
Add correct host key in /home/david/.ssh/known_hosts to get rid of this message.
Offending RSA key in /home/david/.ssh/known_hosts:1
remove with: ssh-keygen -f "/home/david/.ssh/known_hosts" -R 192.168.1.8
RSA host key for 192.168.1.8 has changed and you have requested strict checking.
Host key verification failed.
david@ubuntu-140402C:~$
For the Pro2 running OS6 would the procedure be:
- ssh-keygen -f "/home/david/.ssh/known_hosts" -R 192.168.1.8 or
- ssh-keygen -R ip.address.of.nas?
Or something else?
Many thanks,
David
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.
