[SOLVED] Moved unraid install to new hardware, some issues

[je82]

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?

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!

If your LAN is 1.1.1.x you are definitely doing that wrong.

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

[je82]

Tested removing /boot/config/ssh and rebooting and see if regenerating new keys would solve it but no luck.

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?

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?

[je82]

tested cleaning out puttys saved ssh keys

Computer\HKEY_USERS\SOFTWARE\SimonTatham\PuTTY\SshHostKeys

 

didnt help

[je82]

hmm i guess all the software i was using is now outdated, i updated putty and now i can connect with it, i guess the problem wasn't at unraid after all.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.

Even if you don't directly use cloudflare resources, it will likely cause strange issues when you try to access other resources on the internet that DO use cloudflare.

 

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.
