Getting Started

Server

bash <(curl https://bash.ooo/nami.sh)

nami install brook

brook server -l :9999 -p hello

Client

You may want to use brook link to customize some parameters

Client

Brook GUI will pass different global variables to the script at different times, and the script only needs to assign the processing result to the global variable out

CLI

Before discussing the GUI client, let's first talk about the command line client brook. As we know, after you have deployed the server, you can use the command line client brook to create a local socks5 proxy or http proxy on your machine, and then configure it in your system proxy settings or in your browser to use this proxy. However:

Not all apps will use this proxy, whether they use it is up to the app itself.
Generally, all UDP protocols will not go through this proxy, such as http3.

For the specifics of socks5 and http proxy, you can read this article.

GUI

The GUI client does not use socks5 and http proxy mode, so there is no issue with some software not using the system proxy. Instead, it uses a virtual network card to take over the entire system's network, including UDP-based http3. Moreover, Brook allows us to control network requests programmatically, so it is necessary to have basic knowledge of network requests.

Without Brook: Basic Knowledge of Network Requests

Note: When we talk about addresses, we mean addresses that include the port number, such as a domain address: google.com:443, or an IP address: 8.8.8.8:53

When an app requests a domain address, such as google.com:443
It will first perform a DNS resolution, which means that the app will send a network request to the system-configured DNS, such as 8.8.8.8:53, to inquire about the IP of google.com
1. The system DNS will return the IP of google.com, such as 1.2.3.4, to the app
The app will combine the IP and port into an IP address, such as: 1.2.3.4:443
The app makes a network request to this IP address 1.2.3.4:443
The app receives the response data

In the above process, the app actually makes two network requests: one to the IP address 8.8.8.8:53 and another to the IP address 1.2.3.4:443. In other words, the domain name is essentially an alias for the IP, and must obtain the domain's IP to establish a connection.

With Brook: Fake DNS On

Brook has a Fake DNS feature, which can parse the domain name out of the query requests that an app sends to the system DNS and decide how to respond to the app.

When an app requests a domain name address, such as google.com:443
A DNS resolution will be performed first. That is, the app will send a network request to the system-configured DNS, such as 8.8.8.8:53, to inquire about the IP of google.com
The Brook client detects that an app is sending a network request to 8.8.8.8:53. This will trigger the in_dnsquery variable, carrying information such as domain
1. The Brook client returns a fake IP to the app, such as 240.0.0.1
The app combines the IP and port into an IP address, such as: 240.0.0.1:443
The app makes a network request to the IP address 240.0.0.1:443
The Brook client detects that an app is sending a network request to 240.0.0.1:443, discovers that this is a fake IP, and will convert the fake IP address back to the domain address google.com:443. This will trigger the in_address variable, carrying information such as domainaddress
1. The Brook client sends google.com:443 to the Brook Server
2. The Brook Server first requests its own DNS to resolve the domain name to find out the IP of google.com, such as receiving 1.2.3.4
3. The Brook Server combines the IP and port into an IP address, such as: 1.2.3.4:443
4. The Brook Server sends a network request to 1.2.3.4:443 and returns the data to the Brook client
5. The Brook client then returns the data to the app
The app receives the response data

However, if the following situations occur, the domain name will not/cannot be parsed, meaning that the Brook client will not/cannot know what the domain name is and will treat it as a normal request sent to an IP address:

Fake DNS not enabled: in this case, the Brook client will not attempt to parse the domain name from the request sent to the system DNS and will treat it as a normal request sent to an IP address.
Even with Fake DNS enabled, but the app uses the system's secure DNS or the app's own secure DNS: in this case, the Brook client cannot parse the domain name from the request sent to the secure DNS and will treat it as a normal request sent to an IP address.

To avoid the ineffectiveness of Fake DNS, please refer to this article.

With Brook: Fake DNS Off

When an app requests a domain address, such as google.com:443
A DNS resolution will be performed first. That is, the app will send a network request to the system-configured DNS, such as 8.8.8.8:53, to inquire about the IP of google.com
The Brook client detects that an app is sending a network request to 8.8.8.8:53. This will trigger the in_address variable, carrying information such as ipaddress
1. The Brook client sends 8.8.8.8:53 to the Brook Server
2. The Brook Server sends a network request to 8.8.8.8:53 and returns the result, such as 1.2.3.4, to the Brook client
3. The Brook client then returns the result to the app
The app combines the IP and port into an IP address, such as: 1.2.3.4:443
The app makes a network request to the IP address 1.2.3.4:443
The Brook client detects that an app is sending a network request to 1.2.3.4:443. This will trigger the in_address variable, carrying information such as ipaddress
1. The Brook client sends 1.2.3.4:443 to the Brook Server
2. The Brook Server sends a network request to 1.2.3.4:443 and returns the data to the Brook client
3. The Brook client then returns the data to the app
The app receives the response data

With Brook: Fake DNS On, But the App Uses the System's Secure DNS or Its Own Secure DNS

When an app requests a domain name address, such as google.com:443
A DNS resolution will be performed first. That is, the app will send a network request to the secure DNS, such as 8.8.8.8:443, to inquire about the IP of google.com
The Brook client detects that an app is sending a network request to 8.8.8.8:443. This will trigger the in_address variable, carrying information such as ipaddress
1. The Brook client sends 8.8.8.8:443 to the Brook Server
2. The Brook Server sends a network request to 8.8.8.8:443, and returns the result, such as 1.2.3.4, to the Brook client
3. The Brook client then returns the result to the app
The app combines the IP and port into an IP address, such as: 1.2.3.4:443
The app makes a network request to the IP address 1.2.3.4:443
The Brook client detects that an app is sending a network request to 1.2.3.4:443. This will trigger the in_address variable, carrying information such as ipaddress
1. The Brook client sends 1.2.3.4:443 to the Brook Server
2. The Brook Server sends a network request to 1.2.3.4:443 and returns the data to the Brook client
3. The Brook client then returns the data to the app
The app receives the response data

Handle Variable Trigger

When the in_brooklinks variable is triggered:
- This is currently the only variable that gets triggered before the Brook client starts.
- We know that Brook starts with your choice of a Brook Server, and this variable lets you specify multiple Brook Servers.
- Then during runtime, you can use one of these Brook Servers as needed.
When the in_dnsquery variable is triggered, you can process as needed, such as:
- Blocking, such as to prevent ad domain names.
- Directly specifying the response IP.
- Letting the system DNS resolve this domain.
- Letting Bypass DNS resolve this domain.
- And so on.
When the in_address variable is triggered, you can process as needed, such as:
- Block this connection.
- Rewrite the destination.
- If it's a domain address, you can specify that Bypass DNS is responsible for resolving the IP of this domain.
- Allow it to connect directly without going through a proxy.
- If it's HTTP/HTTPS, you can start MITM (Man-In-The-Middle), which will subsequently trigger in_httprequest and in_httpresponse.
- And so on.
When the in_httprequest variable is triggered, you can process as needed, such as:
- Modifying the HTTP request.
- Returning a custom HTTP response directly.
When the in_httpresponse variable is triggered, you can process as needed, such as:
- Modifying the HTTP response.

Modules

In Brook GUI, scripts are abstracted into Modules. There are already some modules, and thre is no magic, it just automatically combine _header.tengo and _footer.tengo, so you only need to write the module itself.

modules = append(modules, {
    // If you want to predefine multiple brook links, and then programmatically specify which one to connect to, then define `brooklinks` key a function
    brooklinks: func(m) {
        // Please refer to the example in `brooklinks.tengo`
    },
    // If you want to intercept and handle a DNS query, then define `dnsquery` key a function, `m` is the `in_dnsquery`
    dnsquery: func(m) {
        // Please refer to the example in `block_aaaa.tengo`
    },
    // If you want to intercept and handle an address, then define `address` key a function, `m` is the `in_address`
    address: func(m) {
        // Please refer to the example in `block_google_secure_dns.tengo`
    },
    // If you want to intercept and handle a http request, then define `httprequest` key a function, `request` is the `in_httprequest`
    httprequest: func(request) {
        // Please refer to the example in `ios_app_downgrade.tengo` or `redirect_google_cn.tengo`
    },
    // If you want to intercept and handle a http response, then define `httpresponse` key a function, `request` is the `in_httprequest`, `response` is the `in_httpresponse`
    httpresponse: func(request, response) {
        // Please refer to the example in `response_sample.tengo`
    }
})

OpenWrt

Brook OpenWRT: Perfectly supports IPv4/IPv6/TCP/UDP

IPv6

Brook's stance on IPv6 is positive, if your server or local environment doesn't have an IPv6 stack, read this article.

Troubleshooting Steps

After adding your Server to the Brook client
If your Server uses a domain and has not specified an IP address via brook link --address, then Brook client will attempt to resolve the domain's IP using local DNS, preferring AAAA record. For example:
- domain.com:9999
- ws://domain.com:9999
- wss://domain.com:9999
- quic://domain.com:9999
Connectivity check: Go to the Server details page and click Connectivity Check. If it works sometimes but not others, this indicates instability.
After connected
Brook will change your system DNS to the System DNS configured in Brook (by default Google's DNS). In very rare cases, this change may be ignored on Windows, you can confirm this in the system settings.
Test IPv4 TCP: Use Test IPv4 TCP for testing; this test has hardcoded the IP address, so does not trigger DNS resolution.
Test IPv4 UDP: Use Test IPv4 UDP for testing; this test has hardcoded the IP address, so does not trigger DNS resolution.
Test IPv6 TCP: Use Test IPv6 TCP for testing; this test has hardcoded the IP address, so does not trigger DNS resolution.
Test IPv6 UDP: Use Test IPv6 UDP for testing; this test has hardcoded the IP address, so does not trigger DNS resolution.
Test TCP and UDP: Use the Echo Client for testing. If the echo server entered is a domain address, it will trigger DNS resolution.
Ensure the effectiveness of Fake DNS: Fake DNS is essential to do something with a domain or domain address. Generally, enable the Block Google Secure DNS module is sufficient. For other cases, refer to this article.
If your local or Server does not support IPv6: Refer to this article.
macOS App Mode: Refer to this article.
Windows:
- The client can pass the tests without any special configuration on a brand-new, genuine Windows 11.
- Be aware that the Windows system time is often incorrect.
- Do not have other similar network software installed; they can cause conflicting network settings in the system.
- Try restarting the computer.
- Windows Defender may ask for permission to connect to the network or present other issues.
- System DNS may need to be set to 8.8.8.8 and/or 2001:4860:4860::8888
Android:
- The client can pass the tests without any special configuration on the official Google ROM.
- Different ROMs may have made different modifications to the system.
- Permission for background running might require separate settings.
- System DNS may need to be set to 8.8.8.8 and/or 2001:4860:4860::8888
Bypass traffic such as China, usually requires the following modules to be activated:
- Block Google Secure DNS
- Bypass Geo
- Bypass Apple: To prevent issues receiving Apple message notifications.
- Bypass China domain or Bypass China domain A: The former uses Bypass DNS to obtain the IP, then Bypass Geo or other modules decide whether to bypass; the latter bypasses directly after obtaining the IP with Bypass DNS using A records. The latter is needed if your local does not support IPv6.
- If you are a Shiliew user, some modules are enabled by default, which is usually sufficient.
