auparse_interpret_sock_address - Linux

Overview

auparse_interpret_sock_address parses and interprets a socket address string, providing detailed information about its protocol, port, and host address. It’s useful for debugging network-related issues, analyzing socket connections, and understanding network configurations.

Syntax

auparse_interpret_sock_address <socket_address>

Required Argument:

  • <socket_address>: The socket address string to be parsed.

Options/Flags

None.

Examples

Simple Example:

Parse the socket address "127.0.0.1:8080":

$ auparse_interpret_sock_address 127.0.0.1:8080

Output:

Socket address: 127.0.0.1:8080
Protocol: TCP
Port: 8080
Host address: 127.0.0.1

IPv6 Example:

Parse an IPv6 socket address:

$ auparse_interpret_sock_address [::1]:80

Output:

Socket address: [::1]:80
Protocol: TCP
Port: 80
Host address: ::1

Unix Socket Example:

Parse a Unix domain socket address:

$ auparse_interpret_sock_address /tmp/socket

Output:

Socket address: /tmp/socket
Protocol: Unix socket
Port: N/A
Host address: N/A

Common Issues

  • Incorrect Socket Address: Ensure that the provided socket address string is in the correct format.
  • Invalid Protocol: If the protocol specified in the socket address is not supported, an error will occur.

Integration

auparse_interpret_sock_address can be integrated with other commands to analyze network connections more deeply. For example:

$ netstat -anp | grep ":80" | awk '{print $5}' | auparse_interpret_sock_address

This command chain extracts the socket addresses for all TCP connections on port 80 and parses each address using auparse_interpret_sock_address.

Related Commands

  • netstat: Lists active network connections.
  • ss: Displays socket status information.
  • sockstat: Gathers statistics about socket usage.
