Disable ipv6

[Didier B]

How to disable IPV6 on my RPi : ETH is automatically given  a non IPV4 address, and I don't know how to use that in FileZilla. Therefore, it would be great help to let we know either :

• How to disable ipV6 in RPi (Debian 11, bullseye)
  
• Or ... how to use ipv6 in FileZilla !
  
• Or any way to go around this difficuly ...

This disables ipv6 for me completely on my RPi Bullseye systems as well as Ubuntu etc.

Code:

sudo nano /etc/sysctl.conf

Add the following at the bottom of the file:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.tun0.disable_ipv6 = 1

Even simpler if you only want to disable ipv6 on one interface:

Right click on the network manager icon at the top right of the taskbar. Select Wireless and Wired Network Settings, select the interface and press disable IPv6 then Apply.
