Hello !

For those who are interested I've found this tool....

I don't know if it works because I don't have Linux installed on my computer...

I hope you'll enjoy....

TCT-Hydra

I know Hydra. It's a good tool. It try brute-force login on many services, (telnet, ftp, http, ssh) but I think it only works by dictionnary, not real brute-force.
If you've got a user list, and a good disctionnary, it may help.

what ways is there to get a user list?

Well... You could try some default accounts, like root, admin, exploit, oracle, http, apache, lp, guest, test and so on...

Account root/root may often exists you know... Stupid admins !!!

Hum.. Try also to connect to port 25 of the host (sendmail) and VRFY some accounts

dumpster diving

tnx! I'll test it
