Shell Programming and Scripting

Hi Friends,

I have experience in redhat/ Ubuntu OS, but I am very new to solaries os.

my servers OS is Oracle Solaris 10 8/11 s10x_u10wos_17b X86.

I have a file contains 200 servers IPs one by one.

now I want a script to chaeck which IPs are pinging, not pingning.

I prepared the below script.

But the problem is ...if the ip is pinging, script moving to another IP, if IP is not pinging, script is getting strucked and not moving to next line.


please suggest me.

Thanks
Siva

Hello Siva,

You can use following command in place of using only ping.

Code:

/usr/sbin/ping -c5 $line > /dev/null

This will only check for 5 packets in ping and if all are successfully send/received it will be successful.
Let me know if this helps you.

Thanks,
R. Singh

I added as you guided me ...

Code:

 #!/bin/bash
#
#
while read line
do
        /usr/sbin/ping -c5 $line > /dev/null
        if [ $? == 0 ];
        then
        echo "$line is pinging"
        else
        echo "$line is not pinging"
        fi
done < ipreport.txt

even then same output ....
if the ip is pinging then only script is moving to another ip, or else its not moving to another Ip.

my ipreport.txt file is looks like this

vi ipreport.txt

10.x.x.1
10.x.x.2
-
-
-
-
-
10.x.x.100

Instead of

Code:

/usr/sbin/ping $line > /dev/null

try:

Code:

/usr/sbin/ping "$line" 1 > /dev/null

This will create a timeout of 1 seconds. So after 1 second it will give up. Change it to more seconds at will

Note: there should be a space between 1 and >

You may want to run each ping in background to save some waiting time.

yess....this is working out ...


Thank you very much

How do you get the exit states from the bg pings?
I would rather google/download/compile fping
