I am trying to mount a shared drive that exists on my mac in my raspberry pi. I tried searching many different threads on stackoverflow and stackexchange and couldn't find any working solutions. I followed this guide: nixCraft sshfs and tried the steps outlined in: SSH Permission denied (publickey) [closed]. I am able to perform the reverse; ssh into rpi from my mac (as well as win10 pc). Apologize if people consider this a duplicate, but I commented on another thread asking for some assistance, however I was told to post a new question.

This is what I tried:

sshfs -o debug [email protected]:/raspi_pyfies ~/mount/ssh_macdr

which gave me:

FUSE library version: 2.9.9
nullpath_ok: 0
nopath: 0
utime_omit_ok: 0
[email protected]: Permission denied (publickey).
read: Connection reset by peer

I also just tried sshing:

ssh -v [email protected]

and it gave me (last few lines):

debug1: SSH2_MSG_SERVICE_ACCEPT received
debug1: Authentications that can continue: publickey
debug1: Next authentication method: publickey
debug1: Offering public key: /home/pi/.ssh/id_rsa RSA SHA256:#####
debug1: Authentications that can continue: publickey
debug1: Trying private key: /home/pi/.ssh/id_dsa
debug1: Trying private key: /home/pi/.ssh/id_ecdsa
debug1: Trying private key: /home/pi/.ssh/id_ed25519
debug1: Trying private key: /home/pi/.ssh/id_xmss
debug1: No more authentication methods to try.
[email protected]: Permission denied (publickey).

Hopefully someone with experience can shed some light. Thanks.

  • Have you added the pi's public key to the MAC's authorized_keys file? Commented Feb 3, 2020 at 3:45

As noted in one of the answers to your linked question on stackoverflow, run:

ssh-keygen -t rsa

When it asks for file in which to save the key, enter id_rsa. It's also OK to enter nothing, if you're OK with overwriting them under ~/.ssh/id_rsa.

When it asks for a passphrase, leave it empty.

Concatenate the id_rsa.pub file to the end of ~/.ssh/authorized_keys on the destination machine. Then test from the originating machine using

ssh -i id_rsa user@host

If id_rsa is located in ~/.ssh then you can omit the -i option:

ssh user@host

Then you've verified scp, sftp and sshfs will all work.

Important: ssh will not work if permissions on critical paths are too permissive or too restrictive. The file modes must be set as:

chmod 700 ~/.ssh
chmod 644 authorized_keys
chmod 600 id_rsa
chmod 644 id_rsa.pub

  • hi Curt, thanks for your response. I did try all those suggestions before when I searched other threads. I remove .ssh; then re-did everything from scratch. I kept on getting permission denied. I also tried changing the permissions as well. I didn't try different permissions for different files, however. I tried that just now; but no luck. Commented Feb 4, 2020 at 3:04
  • Shoot. It does look like the Pi offered the key id_rsa and it was refused. Do you have other hosts that can ssh into the Mac? Maybe turn on debugging on the Mac side (add LogLevel DEBUG3 in /etc/ssh/sshd_config and restart ssh) and examine the system log. Commented Feb 5, 2020 at 0:38
  • i added the DEBUG3 to the sshd_config file. It was already at DEBUG, i just added the 3. Where can I view the logs? Commented Feb 5, 2020 at 4:06
  • so I found the log in system.log: Feb 3 21:11:56 localhost com.apple.xpc.launchd[1] (com.openssh.sshd): Unknown key for string: SHAuthorizationRight Feb 4 21:24:37 localhost com.apple.xpc.launchd[1] (com.openssh.sshd): Unknown key for string: SHAuthorizationRight Feb 4 21:41:44 username com.apple.xpc.launchd[1] (com.openssh.sshd.###): Service exited with abnormal code: 255 Feb 4 21:48:47 username com.apple.xpc.launchd[1] (com.openssh.sshd.###): Service exited with abnormal code: 255 Commented Feb 5, 2020 at 4:09
  • i substituted jargon characters for the hastags so that it would fit as a comment Commented Feb 5, 2020 at 4:13
