I am trying to configure SSH with public-key authentication on Debian.
I can't seem to get it to work because auth.log keeps saying that can't read key type:...(key line)n.



It keeps complaining about the newline and i can't remove it. I open the file, i delete the newline but it's added again.



Thank you in advance



Edit:I managed to remove the newline, but now i have the same error i had last night. I started with a 4096 RSA key but given this error i thought ssh did not accept 4096 bit keys (i know it is stupid but i had to try). Here is the error from auth.log:



Sep 11 08:36:18 fortknox sshd[5002]: error: buffer_get_string_ret: bad string length 813826338
Sep 11 08:36:18 fortknox sshd[5002]: error: key_from_blob: can't read key type

  • Could you add the relevant line from authorized_keys to your question? Feel free to munge the long hexidecimal part.

Use the original .pub file that was generated (or generate a new key pair) and then add it to authorized_keys this way:



cat id_rsa.pub >> .ssh/authorized_keys
