ssh login mit IdentityFile

[joachimF]

Hi,
I have make a file ~/.ssh/config with the following content

Host mhub
Hostname 192.168.0.22
User root
IdentityFile ~/.ssh/id_rsa.pub

and copied all files of ~/.ssh to the Pi /root/.ssh and/or ~/.ssh
In anycase after ssh mhub I had to type the password.

What I have done wrong?

Hi,

I have no specific knowledge on the PI, but I do know a bit about ssh.

You will need to copy the contents of the pub key (that was generated on the source system) into the authorized_keys file on the PI. This is the line that starts with "ssh-rsa AAAAB3"

Make sure that the authorized_keys has 600 permissions.

Hi Ysbrand,

I have made your suggestions without succes. Here the output of ssh -v

perhaps you find my fault.

Not sure if the following has been set in etc/ssh/sshd_config
HostbasedAuthentication yes

[joachimF]

The content of the public key ~/.ssh/id_dsa.pub of the Home-PC

I copied into the file of the meteohub server
/root/.ssh/authorized_keys

Now when I type in the Home-PC (konsole) "ssh mhub" I logged in without any PW.

further I change in the ~/.ssh/config file
IdentityFile ~/.ssh/id_rsa.pub in
IdentityFile ~/.ssh/id_rsa
