telnet supplying arguments to telnet command
 

how can i supply username and password arguments to telnet command in one line
like

telnet username password

Telnet does not support passing either username or passwords. You must use ssh instead.

not true actually, you can pipe commands into it, or as an alternative approach you can use expect to automate a session. similarily you can't supply commandline passwords in ssh either. ssh is certainly preferable to telnet any day though.
