SCP Without password Setup from HP unix server(source) to oracle linux(target) OracleLinux5.8

Hi,

I set up rsa public key in oracle linux (Target Server -To Copy) with below steps

---

STEP 1: Source Server (HP-UX  Unix Server B.11.31 U ia64)

          Login u_demo_src

          mkdir -p ~/.ssh

          chmod 700 ~/.ssh

          touch ~/.ssh/authorized_keys

          chmod 644 ~/.ssh/authorized_keys

STEP 2: Target Server (OracleLinux5.8 Oracle linux)

        Login u_demo_tgt

          mkdir -p ~/.ssh

          chmod 700 ~/.ssh

          ssh-keygen -t rsa

          scp id_rsa.pub demo@source_server:~/.ssh/id_rsa.pub.tgt

STEP 3: Source Server (HP-UX  Unix Server B.11.31 U ia64)

          Login u_demo_src

          cat ~/.ssh/id_rsa.pub.tgt>>~/.ssh/authorized_keys

          rm ~/.ssh/id_rsa.pub.tgt
