How to stop program of non-interactive SSH call without pseudo-terminal

Let's say I start a program with a non-interactive SSH call (without pseudo-terminal) and exit the session via CTRLC: $ ssh user@server -- sleep 123 ^C This way, the program, in this case sleep 123 for example, is still running on server, even after the SSH session was terminated: $ ssh user@server -- ps -ef | grep "sleep 123" user 12430 1 0 19:28 ? 00:00:00 sleep 123 I am aware of ssh's -t option to have SIGINT sent to the remote sleep instead of the local ssh. But I'm looking for a way to make the remote program stop without having to resort to a pseudo-terminal and specify extra options in the ssh call.
