HowTo ping a Lot of hosts for up|down
Posted: Sat Mar 24, 2012 8:17 pm
Couldn't find one that worked readily, so I made one.
This script is by NO means conclusive or as complete as it could be (needs an alternate check method (Hint Hint Nudge Nudge Wink Wink)... icmp "may" be blocked on some hosts and that will fail in the script and come back as "down", that's not the script's fault.
)
Step1:
Make list of hosts (actual or FQDN or a mash of both...)
save it as say ~/Documents/ping.list
Step2:
Edit /etc/hosts as root and add your IP/hosts details:
Step2:
Create this .sh script and add:
save it as say ~/bin/ping_hosts.sh
Now run it:
Output:
Other more elegant solutions may exist (That's my standard disclaimer folks)
This code is just me hacking for my own creative ends while serving a need.
Enjoy.
