Linux Running set of commands in remote servers in shell script

Hi
Wishing to all.

I am very new joined in an organization as a unix system administrator.

I need a help in preparing a script for a report.

i have a file contains all of the linux/ubuntu servers line by line around 140 servers.
Code:
vi servers.txt

nh01
nh02
nh03
bh01
bh04
-
-
:wq

Now, my script should provide the output like below...
Code:
Server    ping_status   ssh_status   Kernal                   uptime   login_users  
nh01       pingable       ssh able    2.6.18-371.4.1.el5   24 days  30
nh02       pingable       not able     -                           -           -

please help me for the above script.

i can able to write a separate scripts for pinging or not, ssh or not, but not able to take the output in a above format.

and also, if a server is not able to ssh ..then my script gets struck there itself...its not moving further....

Thanks

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME
uudemon.admin, uudemon.cleanu, uudemon.hour, uudemon.poll - Administrative shell scripts for polling remote systems, cleaning up spool directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons SYNOPSIS
These shell scripts reside in the following directory: /usr/lib/uucp DESCRIPTION
All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the scripts, remove the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file. This script reports status to the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID (uucpa) or root. This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com- mand is run with the following parameters: -C7, -D7, X2, -o2, -W1. This script runs the uusched and uuxqt daemons in the background. This script polls the systems listed in the /usr/lib/uucp/Poll file. The uudemon.poll script should be scheduled before the uudemon.hour script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script. FILES
Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files. Contains the uucp file. RELATED INFORMATION
Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1) Files: /usr/lib/uucp delim off uudemon(4)
