source code - hack site

hey at this site http://www.arcanum.co.nz/ i'm at the unknown challenge right now and its find the password for it. I see the source code for the page and sais i should be there and i see the directory for where the password is. Its /etc/passwd. Now how do i see/get that directory? I dont have telnet at my disposal right now, i have to wait till i get home, i knew/think thats the way to do it but is there another way?

I thought the most important rule of a wargame like Arcanum is that you don't ask for help?

But yes, you'd have to use some sort of connection (telnet, ssh, rsh) to the computer to get to the /etc/passwd directory.

Good luck,
