Unable to acces the Wallbox once rooted

[TheMinimaliiiist]

Got an issue to connect to the wallbox.
The pwn was sucessful, when I write the command

ssh -i id_rsa [email protected]

I got the error message
Warning: Identity file id_rsa not accessible: No such file or directory. Unable to negotiate with 192.168.1.29 port 22: no matching host key type found. Their offer: ssh-rsa

Then I found another command line

ssh -oHostKeyAlgorithms=+ssh-rsa -oPubkeyAcceptedAlgorithms=+ssh-rsa [email protected]

And got the following

[email protected]: Permission denied (publickey).

What is the issue ?

[jagheterfredrik]

Add verbose logging to ssh with -vvv

[TheMinimaliiiist]

Can you provide the whole line, I am not a developper so it's tricky for me

[jagheterfredrik]

ssh -i id_rsa -vvv [email protected]

It always says the last line... `Unable to negotiate with 192.168.1.29 port 22: no matching host key type found. Their offer: ssh-rsa`

I found another line online: ssh -oHostKeyAlgorithms=+ssh-rsa -oPubkeyAcceptedAlgorithms=+ssh-rsa [email protected]

But I kept being locked out the Wallbox [email protected]: Permission denied (publickey)

I even tried to delete the known_hosts file, put all the GitHub data on the .ssh file, tried on both Mac, PC W11 and W10, same issue all the time

[jagheterfredrik]

You need to run ssh from within the checked out Github repo so that ssh can find the id_rsa key file. Are you?

[TheMinimaliiiist]

I don't understand you answer so I am surely not doing it the right way.
I have downloaded the raw files from here, put them in a folder and run from that folder.
I also made the same thing from the .ssh folder on a mac and on a PC.
Am I doing it the right way ? What do you mean by "within the checked out GitHub repo" ?

[TheMinimaliiiist]

OK, I was not using the up to date files from Github, those available to be picked on by one aren't oik, those from the whole .rar file are good

[mfgnerd]

I had this same issue. ChatGPT got me this command that seemed to have done the trick. Running from windows 11. had issues on ubuntu origially as well

ssh -o HostKeyAlgorithms=+ssh-rsa -o PubkeyAcceptedAlgorithms=+ssh-rsa -i id_rsa [email protected]
