Known_hosts Question #82

Closed SirGoodenough closed 1 year ago

SirGoodenough commented 1 year ago

Any idea how to clear this warning. I've always seen it but it still works. I thought sending it all to a new server might fix it, it doesn't. I had a server fail so had to reset everything. I think that it is looking for this file on the HA host maybe. Does this on both of my HA systems. Nothing broke, but annoying.

Please see the tab "Documentation", you need to create a known_hosts file.

I didn't see reference to this in the Docs anywhere.
I'm guessing that because Addon is using /ssl (Like the other addons) insteat of the Linux default /,ssh that things are weird. Going with my Gut I googled it and found ssh-keyscan and that looks like it works.

➜  /config git:(master) ✗ cd ../ssl
➜  /ssl  ssh-keygen -f ./[PICK_A_UNIQUE]_ecdsa -t ecdsa -b 521   
answer the questions...
➜  /ssl ssh-copy-id -f -i [SAME_UNIQUE]_ecdsa [LOGIN]@[YOUR IP HERE]
➜  /ssl ssh-keyscan -M [YOUR IP HERE] >> ./known_hosts

Referencing that and these article links would be helpful in here: https://addons.mathesonsteplock.ca/docs/addons/remote-backup/resources

It's gone now...

Did you take a look here? Bildschirmfoto vom 2022-12-12 19-19-53

Yes, you are right, it should be referenced in the documentation as well. Will try to fix that.

SirGoodenough commented 1 year ago

When you said documentation, I looked there, not in the addon top blurb. Missed that one completely.

patman15 commented 1 year ago

Hmm, I just saw that I had already an PR #42 which was merged and the file is there. For some reason it does not show up in the documentation. @ikifar2012 can you fix that? Did I miss something?

SirGoodenough commented 1 year ago

42 is supposed to be the answer to everything somehow...

Still I suggest adding those links in the helpful would have been helpful to me.

I didn's see reference to this in the Docs anywhere. Going with my Gut I googled it and found ssh-keyscan and ran this in a terminal window on HA Host.

➜  /config git:(master) ✗ cd ../ssl
➜  /ssl  ssh-keygen -f ./[PICK_A_UNIQUE]_ecdsa -t ecdsa -b 521   
answer the questions...
➜  /ssl ssh-copy-id -f -i [SAME_UNIQUE]_ecdsa [LOGIN]@[YOUR IP HERE]
➜  /ssl ssh-keyscan -M [YOUR IP HERE] >> ./known_hosts

Got that from here so referencing these article links would be helpful. https://www.ssh.com/academy/ssh/keygen https://www.ssh.com/academy/ssh/copy-id https://www.techrepublic.com/article/how-to-easily-add-an-ssh-fingerprint-to-your-knownhosts-file-in-linux/

oops, had an edit and forgot to push enter...

@SirGoodenough I just fixed the issue, the documentation page was not linked in the sidebar 🤦‍♂️... It should be fixed now, let me know if that appears for you now
