How to mount remote SSHFS via intermediate machine? Tunneling?












24















I would like to mount a remote file system (A) using SSHFS, but sometimes I have IP address, access from which is not allowed. So my plan is to access it via another machine (B) in that network. Do I need to mount A on B and then to mount B (and A) on my local computer? Is there a better way to do it?



Update



Just to clarify the procedure:



First, I make a tunnel



ssh -f user@machineB -L MYPORT:machineA:22 -N


And then I mount the remote file system



sshfs -p MYPORT user@127.0.0.1:/myremotepath /mylocalpath


Is it correct?



How do I destroy the tunnel when I am done?






ssh mount remote tunnel sshfs

    better way to set up tunnel is to have connection to B from GNU screen window using ssh user@machineB -L 2222:machineA:22 -N so you can easily kill it with ^C

yeah tunneling. You connect machine B, create local tunnel (-L) to SSHd port of machine A then sshfs to localhost to the port of newly created tunnel.

    yes if you have sshd listening to port 25 on machine A. then you'll just have to sshfs -p 25 user@127.0.0.1:/path /localpath

You can use option ssh_command of sshfs to do the trick:



sshfs ma: /mnt -o ssh_command='ssh -t mb ssh'


Unmount with the usual



fusermount -u /mnt


Sorry this is 7 years late...

Your connection scheme:
Your machine --> Host B --> Host A



Our solution will use Proxy Jump, introduced in OpenSSH 7.3, so you'll need to check that your version is newer with:



ssh -V


Then you need to configure properly your ~/.ssh/config. For example, if machineB is available with a password login from machineA :



machineB

    HostName {machineB ip address}

    User {machineB username}

    Port {machineB port-number}

    IdentityFile ~/.ssh/{machineB private ssh key}



machineA

    ProxyJump machineB

    Hostname {machineA ip address, maybe in local network}

    User {machineA username}

    Port {machineA port-number}


Finally, create your mountpoint and add line to /etc/fstab



machineB:{machineB mount path}  {your local mountpoint}  fuse.sshfs delay_connect,_netdev,user,idmap=user,follow_symlinks,identityfile={local path to machineB private key},default_permissions,uid={local user uid},gid={local user gid} 0 0
