genhash - Man Page

md5 hash generation tool for remote web pages


keepalived --genhash [options] [-s server-address] [-p port] [-u url]


genhash is a tool used for generating md5sum hashes of remote web pages. genhash can use HTTP or HTTPS to connect to the web page.  The output by this utility includes the HTTP header, page data, and the md5sum of the data. This md5sum can then be used within the keepalived(8) program, for monitoring HTTP and HTTPS services.
