To control and throttle FTP server traffic on a Linux system, you can use a tool such as tc (Traffic Control) to shape and limit the network traffic on the server. Here are the general steps you can follow to use tc to throttle FTP traffic:
Identify the network interface and the IP address of the FTP server:
To use tc to control and throttle FTP traffic, you will need to know the network interface and the IP address of the FTP server. You can use the ifconfig command to display the network interfaces and IP addresses on your system:
ifconfig
Look for the network interface and IP address of the FTP server in the output of the ifconfig command.
Install the iproute2 package:
The tc utility is part of the iproute2 package, which is not installed by default on some Linux systems. To use tc, you will need to install the iproute2 package on your system.
Create a traffic control (tc) queue:
To create a traffic control queue for FTP traffic, you will need to use the tc command with the qdisc (queueing discipline) option and specify the network interface and the IP address of the FTP server. For example:
tc qdisc add dev eth0 root handle 1:0 htb default 10
This will create a traffic control queue for the eth0 interface with a handle of 1:0 and a default class of 10.
Create a traffic class:
To create a traffic class for FTP traffic, you will need to use the tc command with the class option and specify the traffic control queue that you created in the previous step.
