Script which creates a Python-hosted web server for TCP connection testing
Raw
connection_test.sh
#!/bin/bash
webdirectory=$(mktemp -d)
# Set port number for web service
port_number="8080"
# Create temporary directory and change directory
# into the temporary directory
cd "$webdirectory"
cat > "$webdirectory"/index.html << 'Index'
<html>
<head>
<title>Hello World</title>
</head>
<body>
Hello World
</body>
</html>
Index
# Run webservice
/usr/bin/python3 -m http.server "$port_number"

while true; do
  echo -e "HTTP/1.1 200 OK\n\n <html><head><title>Hello World</title></head><body>Hello World</body></html>" \
  | nc -l 8080 
done

Ofc you can pass the "content" many ways like heredoc, from a file, etc...

The webdirectory variable would be useful only if... you would remove the folder at the end of the script or something, otherwise you can cd directly into the temp folder like:
cd $(mktemp -d)
And the port number could be optional like an argument ($1?). Without any argument it would try to bind on 8000/tcp.
But I would still use for a simple task like this netcat instead.
