September 17, 20223 yr Hi, Moved my unraid installation to new hardware, i have the following problems: 1. Cannot ssh to the server, do i have to delete some keys to have them regenerated based new hardware? If so, where do i do this? Quote Sep 17 14:03:23 NAS sshd[11266]: Connection from 1.1.1.4 port 51163 on 1.1.1.7 port 22 rdomain "" Sep 17 14:03:23 NAS sshd[11266]: Unable to negotiate with 1.1.1.4 port 51163: no matching host key type found. Their offer: ssh-rsa,ssh-dss [preauth] 2. Some error in the boot regarding removing an nvidia plugins folder, not sure if i need to bother with this but i've included the message in the picture below. Everything else so far seems to work good! Edited September 17, 20223 yr by je82
September 17, 20223 yr Community Expert If your LAN is 1.1.1.x you are definitely doing that wrong. attach diagnostics to your NEXT post in this thread

I know this, but i like to use it for my LAN, ive been doing it for 7+ years, its not a problem, i dont use cloudflares dns services anyway. Now why is ssh not working is the question
September 17, 20223 yr Author Tested removing /boot/config/ssh and rebooting and see if regenerating new keys would solve it but no luck.
September 17, 20223 yr Author So im no expert on ssh but since i have saved my fingerprints to my server and now it is on new hardware , i guess this may be the issue? Quote debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: ecdsa-sha2-nistp256 SHA256:S1eYR8vNuWzKNzhiEdnUIuVcUY17+DEif/QCZA/jcDs @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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. doing ssh -vv 1.1.1.7 generates a message like this, question is how to do clear the local cache to re-establish a new session and forget the old stuff? Or am i totally in the wrong here barking up the wrong tree?
September 17, 20223 yr Author tested cleaning out puttys saved ssh keys Computer\HKEY_USERS\SOFTWARE\SimonTatham\PuTTY\SshHostKeys didnt help
September 17, 20223 yr Author hmm i guess all the software i was using is now outdated, i updated putty and now i can connect with it, i guess the problem wasn't at unraid after all. Solved.

Any support issue is going to be obscured by your nonstandard use of IP, and it's going to make it more frustrating for anyone attempting to help you troubleshoot. I'm not telling you that you must change, just letting you know how it's effecting you.
