## PURPOSE



Halive is a software used to get a list of alive hosts starting from a list of

hosts whose status is unknown in a short amount of time. It's fast, indeed

halive achieve its speed through its asynchronous design.



Once we have a list of domains/subdomains gathered from the reconnaissance phase,

(for example through [pdlist](https://github.com/gnebbia/pdlist)) we want to check 

fastly which subdomains are alive and which are not.

To this purpose we can use halive and obtain from the initial list of hostnames

only the alive subdomains.

## INSTALLATION



We can install halive simply by doing:

```sh

git clone https://github.com/gnebbia/halive

cd halive

pip install -r requirements.txt

python setup.py install

```



## USAGE



In order to get the list of alive hosts with also the response status code we

can do:

```sh

halive big_list_of_urls.txt

```



The default speed is set through the use of 20 (default) workers, we can

increase the speed by increasing the number of workers, by doing:

```sh

halive big_list_of_urls.txt -t 100

# in this case we use 100 workers

```



We can also print only URLs without response code and store results in a text

file, by doing:

```sh

halive big_lists_of_urls.txt -t 100 --only-urls --output report.txt 

```



We can also only filter URLs which do not reply with 4XX HTTP codes, this can be

done by executing halive in this way:

```sh

halive big_lists_of_urls.txt -t 100 --only-success --only-urls --output report.txt 

```
