# Nas con samba
## Impostare IP statico
Collegarsi al raspberry via ssh, quindi modificare il seguente file, aggiungendo le righe sottostanti:
```bash
nano /etc/dhcpcd.conf
interface wlan0
static ip_address=192.168.1.107/24
static routers=192.168.1.1
static domain_name_servers=192.168.1.1 5.2.75.75
```
## Identificare e partizionare i dischi
```bash
fdisk -l
Disk /dev/sda: 12.73 TiB, 14000519643136 bytes, 27344764928 sectors
Disk model: Generic
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

È possibile identificare i dischi anche con altri comandi:
```bash
lsblk -f

### Partizionare i dischi
```bash
fdisk /dev/sda
Welcome to fdisk (util-linux 2.36.1).
Command (m for help): m
Help:
GPT
M enter protective/hybrid MBR
Generic
d delete a partition
F list free unpartitioned space
l list known partition types
n add a new partition
p print the partition table
t change a partition type
v verify the partition table
i print information about a partition
Misc
m print this menu
x extra functionality (experts only)
Script
I load disk layout from sfdisk script file
O dump disk layout to sfdisk script file
Save & Exit
w write table to disk and exit
q quit without saving changes
Create a new label
g create a new empty GPT partition table
G create a new empty SGI (IRIX) partition table

```
Dopo aver partizionato anche `/dev/sdb`:
```bash
lsblk -f
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINT
sda
`-sda1
sdb
`-sdb1
mmcblk0
|-mmcblk0p1 vfat FAT32 bootfs 37CA-39EC 224.3M 12% /boot
`-mmcblk0p2 ext4 1.0 rootfs a4af13c6-d165-4cbd-a9f6-c961fef8255d 54.4G 3% /
```
## Formattare il disco
Assicurarsi che entrambi i dispositivi siano smontati:
```bash
umount /dev/sda
umount: /dev/sda: not mounted.
umount /dev/sdb
umount: /dev/sdb: not mounted.
```
Quindi formattarli in `ext4`:
```bash
mkfs.ext4 -L "NAS1" /dev/sda1 -v

fs_types for mke2fs.conf resolution: 'ext4', 'big'

### Verificare la formattazione
```bash
file -sL /dev/sda1
/dev/sda1: Linux rev 1.0 ext4 filesystem data, UUID=95db731d-5687-4681-bdac-b0d57dea0260, volume name "NAS1" (extents) (64bit) (large files) (huge files)
file -sL /dev/sdb1
/dev/sdb1: Linux rev 1.0 ext4 filesystem data, UUID=c2ccecd7-5ce2-4441-a134-f8d293831aea, volume name "NAS2" (extents) (64bit) (large files) (huge files)
```
## fstab
Creare i punti di mount nella cartella `/srv/`:
```bash
root@iron:/# cd /srv/
root@iron:/srv# mkdir private/
root@iron:/srv# mkdir public/
```
Procedere quindi a modificare il file fstab:
```bash
root@iron:/media# cat /etc/fstab
proc /proc proc defaults 0 0
PARTUUID=be140fba-01 /boot vfat defaults 0 2
PARTUUID=be140fba-02 / ext4 defaults,noatime 0 1
# I due dischi
UUID=95db731d-5687-4681-bdac-b0d57dea0260 /srv/private/ ext4 defaults 0 2
UUID=c2ccecd7-5ce2-4441-a134-f8d293831aea /srv/public/ ext4 defaults 0 2
```
Se, provando a montare i dischi non vengono restituiti errori, la procedura è avvenuta correttamente e i dischi verranno montati automaticamente all'avvio:
```bash
root@iron:/media# mount /srv/private/
root@iron:/media# mount /srv/public/
root@iron:/media# lsblk -f
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINT

```
## Configurazione di samba

### Global section
In `/etc/samba/smb.conf` aggiungere:
```bash
[global]
#allow hosts = 192.168.1.0/24
workgroup = WORKGROUP
security = USER
server string = FILE SERVER
create mask = 0755
browsable = no
```
### Share section
```bash
[private]
comment = Cartella condivisa
path = /srv/private
browsable = no
read only = no
writable = yes
guest ok = no
create mask = 0775
valid users = @samba
```
Verificare che la configurazione sia corretta col comando:
```bash
testparm
```
Quindi riavviare i servizi:
```bash
systemctl restart smbd.service
systemctl restart nmbd.service
# oppure
systemctl restart smbd nmbd
```
### Aggiunta utente
```bash
adduser davide --home=/home/public --shell=/bin/false --disabled-password
Adding user `davide' ...
Adding new group `davide' (1001) ...
Adding new user `davide' (1001) with group `davide' ...
Creating home directory `/home/public' ...
Copying files from `/etc/skel' ...
Changing the user information for davide
Enter the new value, or press ENTER for the default
Full Name []:
Room Number []:
Work Phone []:
Home Phone []:
Other []:
Is the information correct? [Y/n]
```
#### Assegnare una password all'utente
```bash
smbpasswd -a davide
New SMB password:
Retype new SMB password:
Added user davide.
```
### Aggiungere l'utente al gruppo samba
```bash
usermod -aG samba utente
```
#### Assegnare la cartella condivisa all'utente
```bash
chown davide:samba /srv/private/
chmod -R 770 /srv/private/
ls -lh1 /srv/private/
total 20K
drwxrwx--- 2 davide davide 4.0K Mar 26 17:46 files
```
## Montare automaticamente la cartella condivisa
Installare sul client i seguenti pacchetti:
```bash
sudo apt-get install cifs-utils smb4k
```
Creare nella propria home un file `.smbcredentials` coi seguenti dati:
```bash
username=shareuser
password=sharepassword
domain=workgroupname
```
Quindi `chmod 0600 ~/.smbcredentials`.
Modificare il file `/etc/fstab` nel seguente modo:
```bash
cat /etc/fstab
#
# <file system> <mount point> <type> <options> <dump> <pass>
//192.168.1.107/private/ /media/davide/samba cifs credentials=/home/davide/.smbcredentials,uid=davide,gid=davide 0 0
```
Infine dare il comando `sudo mount -a`. La cartella dovrebbe essere correttamente montata.
```bash
sudo mount -a
mount: (hint) your fstab has been modified, but systemd still uses
the old version; use 'systemctl daemon-reload' to reload.
```
### Connettersi tramite file manager
Inserire nel path:
```bash
smb://server/share_folder/
smb://192.168.1.107/private/
```
