How to Find and Kill a Process Using a Specific Port on Linux (lsof & netstat)

-

Introduction

When executing a process, it may fail to start if the port it needs is already occupied by another process. In such cases, you need to find out which process is using that port and either terminate it or modify its configuration.

Using lsof

lsof (List Open Files) is a command in Linux-like systems that displays a list of all open files and the processes that opened them.

Option explanation:

  • -i: Display the listing of files whose Internet address matches the specified address or protocol.

Example: Check if port 22 is in use

lsof -i TCP:22

Output:

COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
sshd    1116 root    5u  IPv4  33907      0t0  TCP *:ssh (LISTEN)
sshd    1116 root    7u  IPv6  33909      0t0  TCP *:ssh (LISTEN)

Using netstat

netstat is a utility that prints network connections, routing tables, interface statistics, masquerade connections, and multicast memberships.

Common options:

  • -l: Display listening sockets
  • -n: Display numerical addresses
  • -p: Display the process ID and name

Example: Check if port 22 is in use

netstat -lnp | grep ':22'

Output:

tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      1116/sshd
tcp6       0      0 :::22                   :::*                    LISTEN      1116/sshd

Summary

  • Use lsof -i TCP:PORT or netstat -lnp | grep ':PORT' to find which process is using a specific port.
  • Terminate the process using kill <PID> or reconfigure your application to use a different port.

If you're a frequent user of SecureCRT , backing up your session settings and restoring them later is crucial—especially when migrating to a new PC or recovering from a crash. In this guide, you’ll learn how to manually back up and restore SecureCRT settings on Windows , ensuring you never lose your configurations again.

However, these features may not capture all configuration details such as: Backup scripts Custom login scripts Certain session-specific files Therefore, if you want to completely clone your SecureCRT environment—including every session and customization—the safest option is to manually back up the entire Config folder. What Is the SecureCRT Config Folder? SecureCRT stores your personal settings (sessions, host keys, global options, etc.) in a folder located at: C:\Users\<Your username>\AppData\Roaming\VanDyke\Config Th...

How to Set Up Vaultwarden (Bitwarden) on Synology NAS (Best Free Alternative to LastPass)

-
Image
Have you ever felt overwhelmed managing passwords for all your websites? I used to use the same password across multiple sites , which wasn’t secure. To manage them better, I started using LastPass for years. However, in 2019, they changed their pricing policy — now it’s free only for one device for 30 days, and you have to pay to use it across multiple devices . If you're looking for a powerful and free password manager, Vaultwarden is one of the best alternatives to LastPass. What is Vaultwarden? Vaultwarden (formerly known as Bitwarden_RS) is a lightweight, open-source implementation of the Bitwarden server API written in Rust . It is fully compatible with official Bitwarden clients and is ideal for low-resource environments. Example: On a Synology DS916+, Vaultwarden uses 0% CPU and only 64MB of memory while running. My Setup NAS Model : Synology DS916+ DSM Version : DSM 7.1-42661 Update 1 Docker Image : vaultwarden/server Ins...
