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

SSH-ARGV0(1)                                                BSD General Commands Manual                                               SSH-ARGV0(1)

NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling SYNOPSIS
hostname | user@hostname [-l login_name] [command] hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name] [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command] DESCRIPTION
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be processed normally. OPTIONS
