Computer Script to test my network connectivities
Hello folks;
I have about 20 servers in my environment here as well as some applications such as MySql, Oracle, etc..
I need help writing a shell script that can go out and test the Internet connection by pinging servers as well as testing the Oracle & MySql connections.

Is there a way to do that or it has to be done manually?

Thanks in advance for your help

to test the conectevity you can use the ping . if the $? is zero then everything is ok.If all the server have similar oracle/mysql config then you can check the ports on which the application is listening.

Code:
MACHINE=10.0.0.1 # Change to what ever you need
exec 3>/dev/tcp/${MACHINE}/1521
if [ $? -eq 0 ]
then
    echo "oracle accepting connections"
else
    echo "oracle connections not possible"
fi

You can write a perl script using this module: Net::Ping - search.cpan.org

MySQL
for exa our hostfile is
Code:
[root@sistem1lnx ~]# cat hostfile
10.100.110.100
10.100.110.101
10.100.110.102
10.100.110.103
10.100.110.104
.........
10.100.110.120

when ping loss over the %50 let the script send a mail
Code:
while read hostname
do
PL=`ping -c 10 $hostname |grep "% packet"|cut -d"%" -f1|awk '{print $8}'`
 if [ $PL -gt 50 ]
  then
   mail -s "There is a problem with access to $hostname -- ping loss % $PL" mailtoyour@domain.com < /dev/null 
   exit 1
 fi
done < hostfile

Thanks folks.
for amitranjansahu:
I didn't have any luck with the script. I'd like to be able to scan all servers inside /etc/hosts one at a time for ping connection and some servers for a specific connection such as Oracle or MySql

For ygemici:
I did try using your script but it wasn't able to read the hostname ( i made change as well because field 8 is empty and it had to be changed to field 6)
Also my hostfile is under /etc/hosts (the script complained about not knowing the hostfile)
