Termux: fuser, How to Fix

Hey there 👋

Could you share a bit more about your setup?

Are you running Termux on a local Android device or inside a DigitalOcean Droplet? The error Cannot open /proc/net/unix: Permission denied usually points to permission restrictions, but it’s hard to say for sure without more context.

If you’re running this on a Droplet, are you using a regular user or root? And what exactly are you trying to do with fuser? Happy to help if you can provide a bit more detail.

Heya, @mrpinky2022

You need root access to use fuser properly on Android.

If your device is not rooted, fuser will be limited in functionality — especially when it comes to detecting which processes use a file, socket, or port.

If you can shed more details on what you’re trying to achive we can point you on how to set everything.

Regards

Heya,

In Termux, if you’re trying to use fuser and see this error:

Cannot open /proc/net/unix: Permission denied

it usually means that fuser requires elevated privileges (root access) to read certain files under /proc, like /proc/net/unix.

Can you let us know a little bit more on how you actually host Termux, do you have root access?
