ssh에서 ~/.ssh/id_rsa 가 나오는 이유?

ssh로 연결하는 중에 이상한 오류가 나옵니다.

ssh-keygen -P "" -t rsa -f ~/.ssh/my_id
chmod 700 ~/.ssh
chmod 655 ~/.ssh/my_id
ftp로 my_id.pub을 전송
authorized_keys2 에 병합.

ssh -i ~/.ssh/my_id my_id~192.168.0.10하면
"Warning: Identity file ~/.ssh/id_rsa not accessible: No such file or directory."
라는 오류가 나옵니다.

debug의 후반부는 이렇습니다.

~/.ssh/id_rsa 가 나오는 이유가 뭔지, 어떻게 해결해야 하는지 모르니, 질문도 제대로 작성하지 못하겠습니다. 어떻게 하면 될까요?
