This topic explains how to query NAS shared directories on Windows and Linux servers.

Query on Windows (SMB)

List remote directories mounted on the local machine.

Open Command Prompt or PowerShell.
Run net use to list all SMB shared directories mounted on the local machine.

PS C:> net use
New connections will be remembered.
Status       Local     Remote                    Network
-------------------------------------------------------------------------------
OK           Z:        \\1xxx5\sharepath         Microsoft Windows Network
The command completed successfully.

List the shared directories on a remote host.

Open Command Prompt or PowerShell.
Run net view \\[remote-host-ip] to list the SMB shared directories on the remote host.

PS C:> net view \\1xxx5
Shared resources at \\1xxx5

Share name    Type   Used as  Comment
-------------------------------------------------------------------------------
sharepath     Disk            
test          Disk            Home Directories
The command completed successfully.

List shared resources on the local machine.

Open Command Prompt or PowerShell.
Run net share to list the shared resources on the local machine.

PS C:> net share
Share name   Resource                        Remark
-------------------------------------------------------------------------------
C$           C:\                             Default share
D$           D:\                             Default share
IPC$                                         Remote IPC
ADMIN$       C:\Windows                      Remote Admin
The command completed successfully.

Query on Linux (NFS/SMB)

List NFS shared directories.
- Option 1: Run showmount -e [server_ip_or_hostname] on the server or the client.
  Note
  - On the server, you can omit the IP address or hostname.
  - Other showmount parameters include:
    
    -d: Displays only directories mounted by an NFS client.
    
    -a: Lists shared directories on the server and the mount points on the client.
  Example: Run showmount -e 192.168.0.214.
```
root@xxx:~# showmount -e xxx.xxx.x.xxx
Export list for xxx.xxx.x.xxx:
/home/read_only *
/home/all_share *
root@xxx:~#
```
  Note An asterisk (*) indicates that the directory is accessible to all clients. If an IP address is displayed, only that client can access the directory.
- Option 2: Run exportfs -v on the server.
```
root@xxx:~# exportfs -v
/home/all_share
		<world>(rw,wdelay,no_root_squash,no_subtree_check,sec=sys,rw,secure,no_root_squash,no_all_squash)
/home/read_only
		<world>(ro,wdelay,no_root_squash,no_subtree_check,sec=sys,ro,secure,no_root_squash,no_all_squash)
root@xxx:~#
root@xxx:~#
root@xxx:~#
root@xxx:~#
```
  Note <world> indicates that the directory is accessible from any host. If an IP address is displayed, only the specified host can access the directory.

List SMB shared directories.

Run smbclient -L //[server_ip] -U [samba_username] on the server or the client.

Note If the smbclient command is not found, install the tool. For example, on Ubuntu, you can run apt install smbclient.

Example: Run smbclient -L //192.168.0.215 -U test.

Note On the server, you can also use the hostname instead of an IP address.

root@xxx:~# smbclient -L //xxx.xxx.x.xxx -U test
