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) 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.
We can install halive simply by doing:
git clone https://github.com/gnebbia/halive cd halive pip install -r requirements.txt python setup.py install
In order to get the list of alive hosts with also the response status code we can do:
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:
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:
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:
halive big_lists_of_urls.txt -t 100 --only-success --only-urls --output report.txt
