Need Little Help for Online Pentest Lab

Hello hackers !

I just found lab.pentestit.ru.

It's an Online Pentest Lab.

After setting up the VPN to acces the Lab, they give me 2 IP (192.168.101.12 - 192.168.101.13)

So, I do a nmap scan like that:

After Nmap scan, I found this URL: http://192.168.101.12:8080/mail/ <----- It's a login page

I found open port:

25-80-143-8080

First of all, I try a brute-force with Hydra but nothing.

Someone can help me a bit? Google won't

:(

Thank a lot Hackers!
