QA:Testcase OpenSSH

Description

This test case tests OpenSSH basic functionalities (ssh login, scp files).

Setup

1. Ensure that openssh, openssh-clients, openssh-server packages are installed.
2. Ensure that SSH port (22/tcp) is open in the firewall.

How to test

1. On the remote host <remote_host_ip>:
   1. Log-in as root.
   2. Start SSHD service: systemctl start sshd
   3. Add a user <testuser>: useradd <testuser>
   4. Set a password for <testuser>: passwd <testuser>
2. On your local host:
   1. Create 10M test file:

      dd if=/dev/urandom  of=/tmp/testfile bs=1M count=10

   2. Copy the file over SSH: scp /tmp/testfile <testuser>@<remote_host_ip>:/tmp/
   3. Log-in over SSH with <testuser>: ssh <testuser>@<remote_host_ip>
   4. Check for the test file: file /tmp/testfile
   5. Check for the size of the test file: du /tmp/testfile

Expected Results

1. All operations should work.
2. The size of test file on remote machine should match local one.
3. Double check test file integrity with sha512sum
