1. TODO \[NFS\] mounting.
    

```bash
# Create the mount point.
mkdir /mount_path

# Mount
mount -t nfs host:/path /mount_path
```

1. TODO \[Samba\] mounting.
    

```bash
mkdir /mount_path

mount -t cifs -o username=SYNOLOGY_USER_NAME,uid=SYNOLOGY_USER_NAME,gid=SYNOLOGY_USER_NAME \
//host/path /mount_path
```

# Error mapping

1. `mount.cifs: bad UNC` using `mount -t cifs //host` instead of `mount -t cifs /host/`
    
2. `mount.nfs: mount(2): No such device` Your kernel doesn't support, cede please.
    
3. `mount error: cifs filesystem not supported by the system` Your kernel doesn't support, cede please.
