Prerequisites

Install tmux:

# Ubuntu/Debian
sudo apt-get install tmux

Two panes (left/right)

This creates a session named "socktop", splits it horizontally, and starts two socktops.

tmux new-session -d -s socktop 'socktop ws://HOST1:3000/ws' \; \
  split-window -h 'socktop ws://HOST2:3000/ws' \; \
  select-layout even-horizontal \; \
  attach

Four panes (2x2 grid)

This creates a 2x2 grid with one socktop per pane.

tmux new-session -d -s socktop 'socktop ws://HOST1:3000/ws' \; \
  split-window -h 'socktop ws://HOST2:3000/ws' \; \
  select-pane -t 0 \; split-window -v 'socktop ws://HOST3:3000/ws' \; \
  select-pane -t 1 \; split-window -v 'socktop ws://HOST4:3000/ws' \; \
  select-layout tiled \; \
  attach

Tips

Replace HOST1..HOST4 (and ports) with your targets
Reattach later: tmux attach -t socktop
