I just find it annoying that the restore doesn't take into consideration the number of passwords already tested so that the speed is just a messy guess. Great tool, but the password generator is so weak.
If you want to use Hydra I would just recommend getting an iso of Kali linux just go to Kali.org and download the iso file and burn it i'm pretty sure people are gonna get mad at this comment this is just a suggestion.
I notice that some people on this comment page are just asking to access an email account or a game account. keep in mind that THC Hydra brute forces using a dictionary attack, meaning that a file with a bank of common passphrases is run through by the program, to crack an authentication service. You can't just expect it to plug into an auth. service and instantly crack the password, unless you give it limitations (I'm assuming, because I use aircrack-ng with crunch), so it knows where to look. I recommend that you read the README file included. If you don't understand what it says, then... I don't know, man.
I have been using this for my internal ethical hacking tasks to brute force telnet access to Cisco network devices (routers, switches etc) with great success. It is very fast and stable tool. Have been using it on Kali Linux lately.
