SSH and Secure File Transfer

FTP and Telnet are insecure ways of accessing remote systems on the network. Hackers can snip the data passed between computers during FTP/Telnet connection. In particular, they can read a user's password when he logs onto a remote system. Hackers steal such password information to log on to the remote system, then launch further attacks on the Internet under a false identity.

In order to protect data, you are recommended to use a secure way for transfering data called SSH (Secure Shell)/SFTP (Secure File Transfer Protocol). SSH/SFTP is designed as a replacement for Telnet and is the standard for secure file transfer and remote logins over the internet. All network traffic is encrypted and optionally compressed, providing strong authentication measures and secure communications.

You are advised to use SSH/SFTP client program to access the following Information Technology Services remote systems::

Remote Server


personal websites (* support SFTP only)

heterogeneous high performance computing service (* support SSH only)

file transfer between HPC2015 and external computers

high throughtput computing(HTC) service (* support SSH only)

streaming of MP4 video files (* support SFTP only)


If connecting from outside the HKU campus network, staff and students are required to login HKUVPN. Refer to

If connecting within the HKU campus network, HKUVPN login is not required.
