This is a simple website to check if a server is up by being hosted from the said machine.

It uses https and a self-signed certificate. The multithreaded server is written in Python.

How to use

1. Clone the repository

git clone https://github.com/gallbotond/server-up.git

2. At the root of the project create a /secrets folder, and open it

mkdir secrets
cd secrets

3. Create and edit the openssl.cnf with your own data

[req]
distinguished_name = req_distinguished_name
x509_extensions = v3_req
prompt = no

[req_distinguished_name]
C = US
ST = California
L = San Francisco
O = My Company
OU = My Department
CN = localhost

[v3_req]
keyUsage = keyEncipherment, dataEncipherment
extendedKeyUsage = serverAuth
subjectAltName = @alt_names

[alt_names]
DNS.1 = localhost

3. Before running the server, generate an SSL certificate and a private key

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes -config ./openssl.cnf

4. Start the https server with server-up.py

Make sure you are in the website folder!

python3 server-up.py
