I am trying to log into a Xeon Phi 3120A for the first time using Putty, but the log-in is refused and the connection asks for a password.
What I am doing is:
1. Create public and private keys in puttygen (SSH2-RSA 1024 bit)
2. Register the public keys with the Xeon Phi with
micctrl --addssh root -f "C:\Program Files\Intel\MPSS\bin\authorized_keys"
root: Updated with authorized key
3. micctrl --stop and then --start
4. Start putty and log into firstname.lastname@example.org with SSH auth set to use the private keys saved in a ppk file.
There is then a PuTTY Security Alert saying that the new rsa2 fingerprint does not match the one PuTTY has cached in the registry.
If I click Yes to update the cache, the log in says:
Using username "root"
Server refused our key
Any idea what I am doing wrong or what I should try next?
