Login problem at debian lenny

[Mahmudur Rahman Jami <infojami@gmail.com>]

Hi,

 

I am using Debian lenny. I am unable to login to my system since today morning. It shows the following message when I put user account,

 

Usage login [-p] [name]

     -p [-h host] [-f name]

     -p -r host

 

This system is running qmail/webmail services and very important to me.

 

Please help me.

 

Rgds,
