automating username / password entry

I have a database that contains a list of server names, and the password for the root user on several servers (100+). I need to verify the passwords for each of the servers in an automated fashion because the database continues to grow. All of the users that I'm going to test are ROOT. I can't use keys and I can't necessarily use Perl because not every server has it installed and the ones that don't...i can't install it on them. So I was considering using the EXPECT command to get this done.

I have a file that looks like this:
server1 password
server2 password
etc...

What I want to happen (in my head this is how I see it working anyway) is that I run the script and the script reads my file (named login_pass.txt), logs into the 1st server and when prompted it supplies the associated password. If the password fails I would like to have the failures outputed somehow so that I can make a note of them and eventually go back and fix them.

Here is the code that I have come up with so far...

Code:

#!/bin/bash
#!/usr/bin/expect -f
FILE=login_pass.txt
HOSTS=`awk '{print $1}' $FILE`
PASS=`awk '{print $2}' $FILE`
for x in $HOSTS;do
expect "root@$HOSTS:"
ssh -C -q root@$HOSTS "hostname;date /"
#expect "root@$HOSTS:"
send -- "$PASS \r"
send -- "\r"
done
expect eof

I'm really new to scripting in unix so I know I'm doing something wrong and hopefully something easilly fixed. Can someone help me out on this? Also if there is a better way to do this please let me know as I'm open for suggestions.

Thanks for the help!

hosts.equiv

HOSTS.EQUIV(5)						     Linux Programmer's Manual						    HOSTS.EQUIV(5)

NAME

       /etc/hosts.equiv - list of hosts and users that are granted "trusted" r command access to your system

DESCRIPTION

       The hosts.equiv file allows or denies hosts and users to use the r-commands (e.g. rlogin, rsh or rcp) without supplying a password.

       The file uses the following format:

       [ + | - ] [hostname] [username]

       The hostname is the name of a host which is logically equivalent to the local host. Users logged into that host are allowed to access like-
       named user accounts on the local host without supplying a password.  The hostname may be (optionally) preceded by a plus (+) sign.  If  the
       plus  sign  is used alone it allows any host to access your system.  You can expicitly deny access to a host by preceding the hostname by a
       minus (-) sign. Users from that host must always supply a password.  For security reasons you should always use the FQDN  of  the  hostname
       and not the short hostname.

       The  username  entry  grants a specific user access to all user accounts (except root) without supplying a password. That means the user is
       NOT restricted to like-named accounts. The username may be (optionally) preceded by a plus (+) sign. You can also explicitly deny access to
       a  specific  user  by preceding the username with a minus (-) sign. This says that the user is not trusted no matter what other entries for
       that host exist.

       Netgroups can be specified by preceding the netgroup by an @ sign.

       Be extremely careful when using the plus (+) sign. A simple typographical error could result in a standalone plus sign. A  standalone  plus
       sign is a wildcard character that means "any host"!

FILES

       /etc/hosts.equiv

NOTE

       Some  systems will only honor the contents of this file when it has owner root and no write permission for anybody else. Some exceptionally
       paranoid systems even require that there be no other hard links to the file.
