Ethereum: A guide to monitor active connections in Linux
As a user of the popular Ethereum cryptocurrency platform, it is likely to be aware that it is not only limited to buying and selling digital assets. It also serves as a decentralized application network (DAPP), which allows developers to build a wide range of applications, from simple websites to complex games.
But with high performance and robust scalability connections, users can enjoy interactions without problems between their Ethereum accounts and other intelligent contracts in the network. However, an aspect that can affect performance are active connections: how many are currently established on your device or server?
In this article, we will explore ways to monitor and verify the active connections in the Linux systems that Ubuntu executed.
What are active connections?

Active connections refer to the number of TCP/IP connections established between two devices. In a Linux system, each process that is open to incoming connections (that is, not in the background or inactivity) contributes to an “active connection count”. However, it is essential to take into account that this count does not necessarily translate into CPU use or network activity.
Methods to monitor active connections in Linux
Here are two methods to verify the active connections in its Linux system that Ubuntu executes:
Method 1: Use of the lsof command
The 'LSOF command is a powerful tool to purify and monitor the management of the file descriptor. You can use it to list all open files, including those that represent active connections.
`Bash
$ LSOF -I: 80 | GREP "Established"
- This command lists all TCP connections linked to port 80 (the predetermined HTTP port) and verify the established connections.
- TheGrep
(“established” `filter the exit, highlighting only established connections.
Method 2: Use of the ss command
The ‘SScommand is a more traditional tool to monitor the network state. You can use it to list all active TCP connections.
Bash
$ SS -TLNP | GREP "Established"
- This command lists all open TCP connections in the current process tree, verifying the established connections.
- TheGrep
(“established” `filter the exit, highlighting only established connections.
Why monitor active connections?
Monitoring active connections can help you:
- Optimize network performance : By identifying which processes are causing a high network activity, you can optimize the use of resources and improve the general performance of the system.
- Problem solving problems : If a problem arises with your Ethereum connection or network applications, monitoring active connections can reveal clues about where the problem occurs.
Conclusion
The monitoring of active connections in the Linux systems that run Ubuntu provides valuable information about the behavior of your system and helps you optimize performance when necessary. Whether I use lsof oss, these tools will give you an integral vision of what processes are actively involved with the network, which allows you to make informed decisions about the allocation of resources and problem solving problems.
When regularly reviewing your active connections, you can guarantee interactions without problems between your Ethereum accounts and other intelligent contracts in the network. Happy purification!
