reset password

Hi,

on my fileriun installation suddenly the password for my user doesn't work anymore ... I try to reset but the error message I get then is: Failed to send e-mail message. Please contact the site's administrator.

I can ssh into my server ... is there a way to reset my passowrd through commandline? Or to set up the emailing function as obviously the email sending is not installed. Can i install it from CLI?

Thxs
