password

hello,need some help,i just install linuxcnc 2.7. it keep asking wrong password.can some one tell me what went wrong

It is a common mistake with the Wheezy based install (been there, done that, have the T-shirt). The first login prompt is for your username (It only says Login), the next prompt is for your password. If you enter your password at the username prompt by mistake, what ever you enter in the subsequent password prompts will never be correct.
