Problem with Sudo inside a here document

Have a sudo statement inside of a here document. It prompts me for a password, but doesnt wait for me to enter my password. Is there a way I can use the command without sudo or anyway that I can enter the password correctly?

Eg :
Code:
while read  remotehost
do
  ssh -t $2@$remotehost  <<REMOTE

   ls /path/to/file/ | while read line
     do
              sudo  vserver \$line enter
              echo "\$line Hello world"
      done

REMOTE
done < "$remotehostlist"

This asks for password for the following line sudo vserver $line enter. But it doesnt wait for me to enter password. Also if I type something it appears in cleartext.

Please help!!

yppasswd(1)						      General Commands Manual						       yppasswd(1)

NAME
yppasswd - change password in Network Information Service (NIS) SYNOPSIS
yppasswd [name] DESCRIPTION
Note If Enhanced Security is enabled on your system, use the passwd command to change your password, even if NIS is in use. The yppasswd command lets you change your password in the Network Information Service (NIS) map, a network data base service. Only you or the superuser can change your NIS password. When you enter the yppasswd command, the program prompts you for the old password and then for the new password. Note that the passwords are not displayed on the screen. Next, the program asks you for the new password again, to verify that you have typed it correctly. If you do not type the passwords cor- rectly, you will receive an error message after you enter the new password. Your new NIS password must meet one of the following requirements: It must be a combination of at least six alphanumeric characters, or It must be a minimum of four characters, with at least one being non-alphanumeric, such as a control sequence. Note The passwd command does not change the NIS password. This command only changes the local password file (/etc/passwd), and not the NIS mas- ter password file. ERRORS
Your new password does not meet the minimum length requirement. You misspelled your new password or its verification. Your new password can not be activated. It must be different from your old password and your login name. FILES
Password file NIS directory SEE ALSO
