Running simplehttpserver in the current folder

This will run the tool exposing the current directory on port 8000

simplehttpserver

2021/01/11 21:40:48 Serving . on http://0.0.0.0:8000/...
2021/01/11 21:41:15 [::1]:50181 "GET / HTTP/1.1" 200 383
2021/01/11 21:41:15 [::1]:50181 "GET /favicon.ico HTTP/1.1" 404 19

Running simplehttpserver in the current folder with HTTPS

This will run the tool exposing the current directory on port 8000 over HTTPS with user provided certificate:

simplehttpserver -https -cert cert.pen -key cert.key

2021/01/11 21:40:48 Serving . on http://0.0.0.0:8000/...
2021/01/11 21:41:15 [::1]:50181 "GET / HTTP/1.1" 200 383
2021/01/11 21:41:15 [::1]:50181 "GET /favicon.ico HTTP/1.1" 404 19

Instead, to run with self-signed certificate and specific domain name:

simplehttpserver -https -domain localhost

2021/01/11 21:40:48 Serving . on http://0.0.0.0:8000/...
2021/01/11 21:41:15 [::1]:50181 "GET / HTTP/1.1" 200 383
2021/01/11 21:41:15 [::1]:50181 "GET /favicon.ico HTTP/1.1" 404 19

Running simplehttpserver with basic auth and file upload

This will run the tool and will request the user to enter username and password before authorizing file uploads

simplehttpserver -basic-auth root:root -upload

2021/01/11 21:40:48 Serving . on http://0.0.0.0:8000/...

To upload files use the following curl request with basic auth header:

curl -v --user 'root:root' --upload-file file.txt http://localhost:8000/file.txt

Running TCP server with custom responses

This will run the tool as TLS TCP server and enable custom responses based on YAML templates:

simplehttpserver -rules rules.yaml -tcp -tls -domain localhost

The rules are written as follows:

rules:
  - match: regex-match
    match-contains: literal-match
    name: rule-name
    response: response data

For example to handle two different paths simulating an HTTP server or SMTP commands:

rules:
  # HTTP Requests
  - match: GET /path1
    name: redirect
    response: |
              HTTP/1.0 200 OK
              Server: httpd/2.0
              x-frame-options: SAMEORIGIN
              x-xss-protection: 1; mode=block
              Date: Fri, 16 Apr 2021 14:30:32 GMT
              Content-Type: text/html
              Connection: close

              <HTML><HEAD><script>top.location.href='/Main_Login.asp';</script>
              </HEAD></HTML>
  - match: GET /path2
    name: "404"
    response: |
              HTTP/1.0 404 OK
              Server: httpd/2.0
            
              <HTML><HEAD></HEAD><BODY>Not found</BODY></HTML>
  # SMTP Commands
  - match: "EHLO example.com"
    name: smtp 
    response: |
              250-localhost Nice to meet you, [127.0.0.1]
              250-PIPELINING
              250-8BITMIME
              250-SMTPUTF8
              250-AUTH LOGIN PLAIN
              250 STARTTLS
  - match: "MAIL FROM: <noreply@example.com>"
    response: 250 Accepted
  - match: "RCPT TO: <test@example.com>"
    response: 250 Accepted
