1 Install sshfs
Install sshfs package.
$ sudo dnf install -y sshfs
2 Mount SSH with sshfs
Mount SSH to <path> with sshfs. You need write permission to <path>.
$ sshfs <server> <path>
This article mounts to $HOME/mnt.
$ mkdir $HOME/mnt$ sshfs ssh-server.hiroom2.com:$HOME $HOME/mntThe authenticity of host ‘ssh-server.hiroom2.com(192.168.11.96)’ can’t be established.ECDSA key fingerprint isSHA256:jnXzkA7FZ1MW7K2zr9lM87nLt/IxJBIqKyt9EMF7mbc.Are you sure you want to continue connecting (yes/no)? [email protected]’s password:
$HOME in SSH server can be accessed.
$ ls $HOME/mntbin Documents examples.desktop Pictures src VideosDesktop Downloads Music Public Templates
3 Generate SSH key
Generate SSH key for accessing from root user on SSH client to root user on SSH server without password authentication.
Run ssh-keygen on SSH client for generating SSH key.
$ # Run the following command on SSH client.$ sudo ssh-keygen -t rsa -f /root/.ssh/id_rsa -N “”$ sudo cat /root/.ssh/id_rsa.pubssh-rsa AAAAB3Nza<snip> root@ssh-client
Copy public key generated by ssh-keygen on SSH client to authorized_keys on SSH server.
$ # Run the following command on SSH server.$ cat <<EOF | sudo tee /root/.ssh/authorized_keysssh-rsa AAAAB3Nza<snip> root@ssh-clientEOF
You need to access from SSH client to SSH server for adding SSH server fingerprint to known_hosts. This article disables checking finngerprint to SSH server.
$ # Run the following command on SSH client.$ cat <<EOF | sudo tee /root/.ssh/configHost 192.168.11.* StrictHostKeyChecking no UserKnownHostsFile=/dev/nullHost *.hiroom2.com StrictHostKeyChecking no UserKnownHostsFile=/dev/nullEOF
4 Mount SSH on boot
Add mount entry to /etc/fstab. For avoiding mounting NFS before network initialization, you need to add _netdev option. For making x-systemd.automount to mount NFS, you need to add x-systemd.automount to option.
$ SSH_SERVER=ssh-server.hiroom2.com$ SSH_DIR=/$ cat <<EOF | sudo tee -a /etc/fstab${SSH_SERVER}:${SSH_DIR} /mnt fuse.sshfs _netdev,x-systemd.automount 0 0EOF
For access with other user, use <user>@<server>. identityfile option changes SSH key. allow_other, uid and gid option changes ownership at mount point.
$ OPT=_netdev,x-systemd.automount,identityfile=/home/hiroom2/.ssh/id_rsa$ OPT=${OPT},allow_other,uid=hiroom2,gid=hiroom2$ mkdir -p /home/hiroom2/mnt$ cat <<EOF | sudo tee -a /etc/fstabhiroom2@${SSH_SERVER}:/home/hiroom2 /home/hiroom2/mnt fuse.sshfs ${OPT} 0 0EOF
