im using backtrack 4 final

im able to telnet to my router and i can access using my username and password

im trying with hytraGTK if it does find my password

the password list im using is /pentest/passwords/jtr/password.lst with number of tasks of 128

it didnot find the password, so i thought the password im using is not in the password.lst

so i added the password as the 3rd password in password.lst

still it didnot find the password

but i can see it doest [ATTEMPT] with correct password

but in 23[Telnet] i cant see its tryin with correct password, and then it ends

then i created test.lst with one password, and hydra does show the password

why hydra doesnt detect the password in password.lst?
