tcpdump 로그에 대한 문의

제가 사용하는 IP : 192.168.10.106

테스트용 서버 IP : 192.168.10.102

ssh 로 접속하여 tcpdump를 해보면 아래와같은 로그가 초당 계속올라갑니다. 그래서 다른 다른 포트에서 접속된 기록을 보는데 힘드네요.

tcpdump not port 22 이렇게 하면 로그가 안나오긴 하지만  ssh에 대한 로그를 볼 수가 없어서요. 질문내용은 왜 명령어를 치지 않아도 아래와 같은 패킷이 계속 발생하는지 모르겠구요. 또 하나 포트 22를 막지않고 해결할 수 있는 방법이 있을까요?
