ssh를 통해 iperf3 -s 옵션으로 실행 했는데
결과 내용이 ssh 터미널을 통해 나오지 않아서 3 ai들에게 물어보니
cluade가 알려줌. 그 와중에 gemini는 도움이 안되고 chatGPT는 파일로 떨구라고 알려줌.. (야이 -_-)
아무튼 -t 라는 옵션을 주면 잘 나온다. 신기하네..
-T Disable pseudo-terminal allocation.
-t Force pseudo-terminal allocation. This can be used to execute
arbitrary screen-based programs on a remote machine, which can be
very useful, e.g. when implementing menu services. Multiple -t
options force tty allocation, even if ssh has no local tty. |
iperf3 가 취소되어 종료되고 나서 한번에 iperf3 서버쪽 결과가 나옴. 일종의 버퍼링 상태인가..

그 와중에 iperf3 -s 를 실행한 ssh를 종료하면 PPID 1번으로 붙어 버린다. 야이 -_-
마치 -D / --daemon 옵션을 주고 한 것 같아지냐
$ ps -ef | grep iperf3
falinux 811482 1 2 12:12 ? 00:00:02 iperf3 -s |
딱이네.. 머지? 터미널이 없으면 자동으로 daemon 모드로 작동하나?
$ iperf3 -D -s
$ ps -ef | grep iperf3
user 811482 1 1 12:12 ? 00:00:02 iperf3 -s |
아무튼 대망의(?) -t 옵션. 잘 된다.
$ ssh -t localhost "iperf3 -s"
