Guides to bypass block in CUMT without any account

[Cnily03]

Requirements

• A server that can visit the internet. We'd recommend a server located in campus with accessible IP address for your device, as it has access to both public internet and local network. For example, (virtual) machine in the machine room.
• If convenient, it's better to have a gateway device, such as router.
• You are accessible to CUMT_Tec Wi-Fi or network port.

Test the connection

Download sing-box CLI both on your computer and your server.

Clone this repository on your server.

Connect Wi-Fi or network port to CUMT_Tec on your computer.

Assumptions: The server IP for you to visit is 202.11.407.21 (same as the visit in final route).

Generate certificate and key pairs

Run following commands to generate on your server.

Please run one by one.

You can modify the options like years or bits to meet your needs.

# create private key
openssl genpkey -algorithm RSA -out server.key -pkeyopt rsa_keygen_bits:2048
# create certificate signing request
openssl req -new -key server.key -out server.csr
# create self-signed certificate
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

It will prompt several inputs. We recommend you type self-owned domain in Common Name (CN) field.

The generated files should be in data/ directory.
