I use BackTrack 5R3 and Hydra 7.3

I've tried to use hydra to find the password on my D-Link DIR-600.
With the command
Code:
hydra -l admin -P /root/crack/all.lst -e s -t 5 -w 16 -f -s -v 192.168.200.250 http-get /
OWASP Mantra makes me see this header when i have the correct login

http://192.168.200.250/session.cgi

How do I see if I find the hydra password?
I also tried this comand:
Code:
hydra -v -l admin -P /root/crack/all.lst -e s -t 5 -f -m /session.cgi 192.168.200.250 http-get
response with "[WARNING] Unusual return code: 5 for admin:....."

I have to use another program for this type of login page?

Thanks.
