Remote Access / File Transfer

Setting Up WinSCP Access to a Mac or Linux Host

A short technical note on using WinSCP and SFTP to transfer files securely between a Windows machine and a Mac or Linux host.

Technical Note / Draft

Concepts

  • WinSCP is a Windows client for file transfer.
  • SFTP uses SSH.
  • The remote machine must have SSH enabled.
  • The user needs the correct host/address, username, password or key, and permissions.

Common Setup Steps

  • Enable SSH / Remote Login on the Mac or Linux host.
  • Confirm both devices are on the same network or reachable through a secure remote access method.
  • Use SFTP, not plain FTP.
  • Enter host, username, and authentication method.
  • Test access with a simple file transfer.
  • Disable or restrict access when no longer needed.

Common Connection Problems

  • Wrong username.
  • SSH not enabled.
  • Firewall blocking access.
  • Devices on different networks.
  • Password authentication disabled.
  • Wrong protocol selected.
  • Incorrect permissions.

Skills Demonstrated

  • SSH/SFTP basics
  • Secure file transfer
  • Remote troubleshooting
  • Cross-platform support
  • Clear setup documentation

Security Note

SFTP is preferred over plain FTP because it uses SSH. Public-facing access should be avoided unless properly secured.
