NFS on Xiaomi Redmi 9T: how the network protocol works and why you need it

What is NFS and why is it relevant for Redmi 9T?

If you have ever had to access files on your computer or NAS-server directly from your smartphone, the protocol NFS (Network File System is what you need, unlike the traditional cloud services like Google Drive or Mi Cloud, NFS It allows you to connect network folders as local drives, providing high data transfer speeds and minimal latency. 9T, where limited internal storage (64/128 GB) can quickly end when working with large files - video in 4K, RAW-Photos or projects in Adobe Premiere Rush.

NFS was developed by Sun Microsystems in 1984, but is still one of the most efficient ways to share files on local networks. On Redmi 9T, this protocol is not supported out of the box (unlike SMB or FTP), but it can be activated using third-party applications. The main advantage of NFS over alternatives is the low load on the processor (important for the budget Snapdragon 662 in Redmi 9T) and the absence of additional encryption, which speeds up data transfer.

But there are nuances: NFS requires configuration on both sides, on the server (PC/NAS) and on the client (your smartphone). If you've never worked with network protocols, the process can seem complicated. But don't worry, in this article, we'll take everything from selecting an application to solving typical connection errors.

NFS vs SMB vs FTP: Which Protocol Is Best for Redmi 9T?

Before diving into NFS setup, it’s worth understanding how it differs from other popular file sharing protocols.

And you can see from the table that NFS is faster, but it's less secure and easy to set up, for example, if you want to stream video from Redmi 9T to the NAS in synchrony with editing in CapCut, NFS is the best choice, but if you want to access working documents, you'll want to use SMB or WebDAV, which is more secure.

Another important point is that NFS is sensitive to network quality. If your Redmi 9T is connected to 5 GHz Wi-Fi, file sharing speeds will be close to wired network. But at 2.4 GHz or when the signal is weak, there may be delays. Before setting up the NFS, check your Wi-Fi speed using the WiFi Analyzer app.

💡

If you want top speed but aren’t ready to mess around with NFS setup, try SMB 3.0 – it’s almost as fast as performance, but easier to use on Xiaomi.

How to set up NFS-server for connection to Redmi 9T

To connect to NFS-You can do this with a smartphone, you have to set up a server first:

• 🖥️ Windows computer (through third-party utilities like haneWIN) NFS Server or FreeNFS)
• 🐧 Linux/Pi-server (built-in support) NFS)
• 📦 NAS-device (Synology, QNAP, TrueNAS, et al.)

Consider setting up on the example of Linux (Ubuntu), as this is the most reliable and free option:

1. Install. NFS-server: sudo apt update && sudo apt install nfs-kernel-server
2. Create a folder for access and assign rights: sudo mkdir -p /mnt/nfs_share sudo chown nobody:nogroup /mnt/nfs_share sudo chmod 777 /mnt/nfs_share
3. Edit the configuration file /etc/exports, line: /mnt/nfs_share *(rw,sync,no_subtree_check,no_root_squash) Here * means that access is allowed for all devices on the network. IP-address of your Redmi 9T.
4. Reset the server: sudo exportfs -a sudo systemctl restart nfs-kernel-server

For Windows, you will need additional software, for example, in haneWIN NFS Server, you will need:

1. Specify the folder for export.
2. Add IP-Redmi address 9T list of authorized clients.
3. Launch the server.

Best apps to work with NFS on Xiaomi Redmi 9T

Since MIUI supportive NFS And in fact, you're going to need a third-party app. We tested a few options and we picked the top one.-3:

1. NFS Manager (from Martin Marconcini) is the simplest solution with a minimalist interface, supports folder mounting as local drives, but requires root rights to work properly. ✅ Pros: free, open source, stable operation. ❌ Cons: No support NFSv4, It is difficult to set up without Linux knowledge.
2. Total Commander + Plugin NFS — Universal file manager with a plugin for NFS. It does not require root, but it works slower than native mounting. ✅ Pros: familiar interface, support for other protocols (FTP, WebDAV). ❌ Cons: Plugin paid (~200 rubles.), there is no automatic connection at launch.

FX File Explorer is another file manager with NFS support via extension. Suitable for basic viewing and copying files.

• ✅ Pros: beautiful interface, support for cloud services.
• ❌ Cons: NFS-Extension paid, no mounting as a disk.
• Click Connect. If you're set up correctly, you'll see the contents of the network folder.

Important: The first connection may result in a "Permission denied" error, which means that the server has incorrectly configured access rights. /etc/exports server and restart NFS-service.

💡

Without root rights, you can only view and copy files through a file manager. To mount NFS as a local drive (for example, to work in Kodi), you will need root access.

Typical errors and their solution

When working with NFS on Redmi 9T, users often face the following problems:

• 🚫 "Connection refused – the server is not responding. ⚠️ Warning: Make sure the server is running NFS-The service (sudo systemctl status nfs-server on Linux) and the firewall does not block port 2049. NFS launched at services.msc.
• 🔒 "Permission denied - no permissions. Check: folder rights on the server (chmod) 777 /path/to/daddy. Settings in /etc/exports (must be allowed access to the IP Your phone, available option no_root_squash into /etc/exports, If you are using root on behalf of.
• 🌐 "Network unreachable: phone and server on different networks. Solution: Connect both devices to the same Wi-Fi network. If you need an external connection, set up port port port port port port port port port port port on the router (port 2049 on the router) IP server).
• ⚡ "Slow transfer speed: Possible reasons: 2.4 GHz Wi-Fi is used (switch to 5 GHz). CPU htop enabled encryption (NFS It does not support it natively, use it. VPN safe).

If you are using NFS Manager with root rights and the connection is still not working, check the error log via adb logcat:

adb logcat | grep -i nfs

This will help identify a specific problem (e.g., memory shortage or conflict with other network services).

How to protect data when using NFS

NFS doesn't initially encrypt traffic, so the data being transmitted can be intercepted on the local network.

• 🔐 Restrict access by IP — into /etc/exports point out IP-Redmi address 9T, not *.
• 🛡️ Use it. VPN — if you need to connect to NFS From the outside, configure WireGuard or OpenVPN on the router.
• 🔄 Regularly update the server - vulnerabilities in older versions NFS (particularly v2 and v3) They can be used for attacks.
• 📂 Do not store sensitive data in plaintext - if NFS-folder contains passwords or personal documents, encrypt them using VeraCrypt.

Alternatively, if security is critical, consider using SSHFS (FUSE over SSH).This protocol encrypts all traffic but runs slower than NFS. To connect to Redmi 9T, you'll need the Termux app and packet installation:

pkg install openssh sshfs


sshfs user@server:/path/to/folder /sdcard/folder on phone

💡

If you need to temporarily open files to a friend, but you don’t want to set up NFS, use the Temporary Share in the Solid Explorer app – it creates a temporary link over HTTP(S) without the need for complex settings.
