shutdown session

Terminate a client’s stream.

Description Jump to heading #

When a client connects to the load balancer, the load balancer maintains a stream with that client until their connection with the backend server has finished. You can see active streams with the show sess command. Use shutdown session to stop a specific stream. Streams were formerly called sessions.

Examples Jump to heading #

Use show sess to display a list of active streams:

nix
echo "show sess" | \
  sudo socat stdio tcp4-connect:127.0.0.1:9999

nix
echo "show sess" | \
  sudo socat stdio tcp4-connect:127.0.0.1:9999

The first field is the stream’s unique identifier, which you can pass to shutdown session to terminate the stream:

nix
echo "shutdown session 0x55f09d21c9e0" | \
  sudo socat stdio tcp4-connect:127.0.0.1:9999

nix
echo "shutdown session 0x55f09d21c9e0" | \
  sudo socat stdio tcp4-connect:127.0.0.1:9999
