I'm trying to set up a password-less mount of a remote server using sshfs and fuse. The remote server is running on a non standard port and I will be using a ssh key pair to authenticate.
When successful I will be repeating this for three more remote servers each with different keys so I do need to be able to specify which key maps to which remote server.
I based my modifications off this tutorial
- The public key is in remote:authorized_keys
- I have added my local user to the
- I have edited my local
~/.ssh/configto have (per server):
Host [server_ip] Port = [port] IdentityFile = "~/.ssh/[private_key]" User = "[user]"
Whenever I try to mount the remote server locally I get prompted for the remote user's password (not my private key's password). The remote user has a long randomly generated password that I'd like to not have to save or remember and so keys is how I want to do this.
I can connect through ssh (combined with the
~/.ssh/config file) using the command
ssh [ip] so I know that the config file can be read correctly as I am asked for my key's passphrase not the remote user's.
To even attempt to connect to the remote server I have to manually specify the full connection details in the command: `sshfs [user]@[ip]:[remote_path] [local_path] -p [port]
What I've tried so far:
- ssh-add /path/to/key (successful addition)
PreferredAuthentication = publickeyin ~/.ssh/config
- sshfs -o IdentityFile=/path/to/key user@ip:/ /my/mnt/dir
- sshfs user@ip:/ /my/mnt/dir -o IdentityFile=/path/to/key
- temp rename of key to default of
- sshfs -F ~/.ssh/config
Is there a remote or local configuration file that I'm overlooking? Some switch or option that I need to include in the call to sshfs (tried -F) to force it to read and use my ssh config?
ssh -v -p [port] [user]@[remote_ip]

I found the problem. I was trying to mount the remote location to /mnt/new_dir using sudo. If I mount to a location within my local home then it works.
sshfs -p [port] [user]@[ip]:/ /home/[me]/tmp/mount.
I have now done a
sudo chown root:fuse /mnt/new_dir and
sudo chmod 774 /mnt/new_dir and I believe that all's working as intended.
Are there any security issues with this set up that I need to be aware of? (My own user and root are the only members of of the
