Jérôme,
thanks! "hydra -s 8080 -l admin -p pA55w0Rd -f -v -t 1 192.168.1.1
http-get /" did the thing! Example below:

user
pA55w0Rd
Admin
Administrator
[root@ ~]# hydra -s 8080 -l admin -P /root/words.txt -t 1 -f -v

When should one use http-head? In addition, I have read many people
complaining(mainly in backtrack-linux.org/forums) about "-t" feature
in hydra as it runs by default 16 parallel tasks simultaneously and
may skip passwords in password file.. Jérôme mentiod this as well. Is
there a fix for this or is it a hydra bug at all?

Hi Martin,

Why are you using http-head instead of http-get ?

Your browser is actually doing "GET / HTTP/1.0",  not "HEAD / HTTP/1.0"

Jérôme,

I tried with "-t 1", but it did not help. Finally I tried with such command:

..and still no success. If I enter "admin" to the "User Name: " box
and "pA55w0Rd" to the "Password: " box in my web browser, I'm able to
log in. What might be wrong?


Thanks for all the suggestions, I'll check Mezcal and NiX. In
addition, any experience with ncrack(http://nmap.org/ncrack/man.html)
in case of HTTP(S) brute-force cracking?

regards,
martin

Hi Martin,

Sometime I get this problem when I use multiple parallel tasks. (by
default 16)

Try with only one (-t 1) to see.

Cheers,
Jérôme

Correct "User name: " is "admin" and correct "Password: " is
"pA55w0Rd". They work fine if I type them in manually to the
"Authentication required" window, but for some reason I can't get in
using the hydra with words.txt password file, which contains

What might cause this? If any additional information is needed, please ask!
