The script is designed to scan Cloudflare's edge IPs and locate ones that are viable for use with v2ray/xray. It aims to identify edge IPs that are accessible and not blocked.

• Linux
• Python (>=3.6)
• Libraries
  • requests
  • pysocks

• Install prerequisites

sudo apt update && sudo apt install python3-pip git -y

• Clone the project

git clone https://github.com/MortezaBashsiz/CFScanner.git

• Change directory

cd CFScanner/python/

• Install required packages

pip install -r ./requirements.txt

• create a config json file (e.g., myconfig.json) with the following content. replace the values with your own!

{
	"id": "248ecb72-89cf-5be7-923f-b790fca681c5",
	"host": "scherehtzhel01.sudoer.net",
	"port": "443",
	"path": "api01",
	"serverName": "248ecb72-89cf-5be7-923f-b790fca681c5.sudoer.net"
}

• To run without providing a subnets (CIDRs) file and using 8 threads:

python3 cfFindIP.py --threads 8 --config ./myconfig.json

• To run on a list of subnets (recommended). Each line

python3 cfFindIP.py --threads 8 --config ./myconfig.json --subnets ./mysubnets.selection

• To run with a minimum acceptable download speed (in KBps)

python3 cfFindIP.py --threads 8 --config ./myconfig.json --subnets ./mysubnets.selection --download-speed 100

• To run with a minimum acceptable download and upload speed (in KBps)

python3 cfFindIP.py --upload-test --threads 8 --config ./myconfig.json --subnets ./mysubnets.selection --download-speed 100 --upload-speed 25

• To run and try each IP multiple (3 in this case) times. An IP is marked ok if it passes all the tests.

python3 cfFindIP.py --upload-test --threads 8 --config ./myconfig.json --subnets ./mysubnets.selection --download-speed 100 --upload-speed 25 --tries 3

Each line of the subnets file must be a Cloudflare subnet (IPv4 or IPv6) in CIDR notation or a single IP (IPv4 or IPv6):

1.0.0.0/24
108.162.218.0/24
108.162.236.0/22
162.158.8.0/21
162.158.60.0/24
162.158.82.12
2606:4700::/120
2606:4700:3032::6815:3819
...

--threads|-thr: Number of threads to use for parallel computing
--config|-c: The path to the config file. For confg file example, see ClientConfig.json
--subnets|-sn: The path to the custom subnets file. each line
should be either a single ip (v4 or v6) or a subnet in cidr notation (v4 or v6). If not provided, the program will read the cidrs (v4 only) from asn lookup
--tries: Number of times to try each IP. An IP is marked as OK if all tries are successful.
--download-speed: Minimum acceptable download speed in kilobytes per second
--upload-test: If True, upload test will be conducted as well
--upload-speed: Mimimum Maximum acceptable upload speed in kilobytes per second
--download-time: Maximum (effective, excluding latency) time to spend for each download.
--upload-time: Maximum (effective, excluding latency) time to spend for each upload
--download-latency: Maximum allowed latency (seconds) for download
--upload-latency: Maximum allowed latency (seconds) for upload
--use-xray: If true, xray will be used, otherwise v2ray

• In the current version, an IP is marked "OK", only if it passes all tries of the experiment
• The size of the file for download is determined based on the arguments download-speed and download-time (similar for upload as well). Therefore, it is recommended to choose these parameters carefully based on your expectations, internet speed and the number of threads being used

The results will be stored in the results directory. Each line of the generated csv file includes a Cloudflare edge ip together with the following values:

• avg_download_speed : Average download speed in mbps
• avg_upload_speed: Average upload speed in mbps
• avg_download_latency: Average download latency in ms
• avg_upload_latency: Average upload latency in ms
• avg_download_jitter: Average jitter during downloads in ms
• avg_upload_jitter: Average jitter during uploads in ms
• download_speed_1,...,n_tries: Values of download speeds in mbps for each download
• upload_speed_1,...,n_ties: Values of download speeds in mbps for each upload
• download_latency_1,...,n_tries: Values of download latencies in ms
• download_latency_1,..._n_tries: Values of upload latencies in ms

For each time running the code, a result file is generated in the result folder with the datetime string to avoid overwriting (e.g, 20230226_180502_result.csv)
