cant login

somthing has happened to my server today im not sure what though. i tried loging in to da but got incorect pass, so i first thought HACKER but my root p[ass works for the server so i guess not. i reset my admin pass useing

passwd admin

it worked but when i tried the new pass i got the same message

Invalid login. Please verify your Username and Password

i just tried two other passes all 3 crarecters long and a word so i wouldent mess it up when typeing but nothing.

whats going on.

any error appearing in your log file?

/var/log/directadmin/error.log

all fixed. it seemed i ran out of hard drive space. now i need to find out how i go to having 80% free of a 160gb drive to 0.5% in two days.
