I have set up public key authentication before and never had this much trouble… I am not sure what I am missing, but I have done all of the following:
- Ensured the private and public key match (they were created by puttygen, and i use the same key for github )
- PubkeyAuthentication is set to yes
- AuthorizedKeysFile %h/.ssh/authorized_keys
- AuthorizedKeysFile has my public key in it.
- AuthorizedKeysFile is set to mode 600 (i’ve tried 644, 700, 777… i know ssh server usually blocks any attempt to use these if permissions are too open, but idk what else to try)
- ~/.ssh is set to mode 700
- id_rsa.pub is set to mode 600
- The user and group are set to the proper user… what am I missing?

Ok… apparently it was an issue with copying the file over a remote connection.
I ran dos2unix on my id_rsa.pub, then cleared out authorized_keys and then cat id_rsa.pub >> authorized_keys…
boom, it works. Thanks to DEBUG3. (Why doesn’t verbose give key failure information…?)
I also had this same issue.
I solved it by
- Running puttygen
- Loading the private key I had generated
- Copying “Public key for pasting into OpenSSH
authorized_keysfile” into a newpub_key.txtfile locally - Using winscp to copy that file up to my server under the .ssh folder
- Deleting the
authorized_keysfile via rmauthorized_keys - Installing dos2unix via
sudo apt-get dos2unix(I’m running Ubuntu) - Converting the windows generated file to unix style line endings via
dos2unix pub_key.txt - Copying the pub key into
authorized_keysvia catpub_key.txt>>authorized_keys
This finally allowed me to putty into my box as all the tutorials described.
