#### SSHFS mounts
|
||||
|
||||
To connect to and mount remote shares using SSHFS, `nnn` requires the following:
|
||||
|
||||
1. ssh configuration file `~/.ssh/config` should have the host entries. sshfs reads this file.
|
||||
2. `NNN_SSHFS_MNT_ROOT` should be set to the **absolute path** to the directory under which `nnn` creates the mount point for a host. The mount point is the same as the host name.
|
||||
|
||||
Example host entry for a Termux environment on Android device:
|
||||
|
||||
```
|
||||
Host phone
|
||||
HostName 192.168.0.102
|
||||
User u0_a117
|
||||
Port 8022
|
||||
```
|
||||
|
||||
If `NNN_SSHFS_MNT_ROOT` is set to `/home/user/remotes`, the above host `phone` will be mounted at `/home/user/remotes/phone`. `nnn` creates the directory `phone` if it doesn't exist.
|
||||
|
||||
To unmount a mount point highlight it in `nnn` (so that it's the current entry) and press the relevant keybind to unmount. It might be a good idea to bookmark `NNN_SSHFS_MNT_ROOT`.
|
||||
|
||||
Notes:
|
||||
|
||||
1. `nnn` places you inside the mount point after both mount and unmount. This is done so you can ensure the operation completed successfully. To jump back to the last directory, press the usual <kbd>-</kbd>.
|
||||
2. `nnn` doesn't delete the mount point on unmount. This is to prevent accidental data loss.
