RabbitMQ tcp_listen_options Binary
The binary is located under sbin/tcp_listen_options in the RabbitMQ installation directory.
The TCP listen options tool enables you to retrieve and change the TCP stack options of a listening socket. It’s mostly useful for changing the TCP keep-alive options, like the keep-alive interval and the keep-alive count (see below). Also, it’s possible to retrieve and change the TCP congestion control algorithm, e.g., use CUBIC instead of Reno.
Overview of Tcp_listen_options
The tcp_listen_options tool supports various options for modifying the behavior of a listening socket. Some of the commonly used options include:
- TCP keep-alive options: These options control how the socket handles keep-alive probes. The keep-alive interval specifies the time between probes, and the keep-alive count specifies the number of probes to send before declaring the connection dead.
- TCP congestion control algorithm: This option allows you to specify the congestion control algorithm to be used by the socket. Common algorithms include Reno, CUBIC, and BBR.
- TCP window size: This option controls the size of the receive and send buffers used by the socket.
The syntax for using the tcp_listen_options tool is as follows:
tcp_listen_options
Where:
- <options>: Specifies the options to be applied to the socket.
- <socket>: Specifies the listening socket to be modified.
Using Tcp_listen_options to Change TCP Keep-Alive Options
The following command shows how to change the TCP keep-alive interval to 60 seconds and the keep-alive count to 5:
tcp_listen_options --set-keepalive-interval 60 --set-keepalive-count 5
This command will modify the TCP keep-alive options for the specified listening socket. The new keep-alive interval will be 60 seconds, and the new keep-alive count will be 5.
Using Tcp_listen_options to Change the TCP Congestion Control Algorithm
The following command demonstrates how to change the TCP congestion control algorithm to CUBIC:
tcp_listen_options --set-cong-ctrl cubic
This command will modify the TCP congestion control algorithm for the specified listening socket. The new congestion control algorithm will be CUBIC.
Conclusion
The tcp_listen_options tool is a powerful tool that can be used to modify the behavior of listening sockets. It can be used to change TCP keep-alive options, TCP congestion control algorithms, and TCP window sizes. By modifying these options, you can optimize the performance of your network applications.
