BrianDStark has asked for the wisdom of the Perl Monks concerning the following question:
I am able to ping manually from a windows platform to a linux platform, but I can't ping within my script using Net::Ping. I'm pretty sure this is because Net::Ping does a deeper transaction. I vaguely remember "fixing" this issue with a big hammer by turning off the firewall on my Linux platform. This was OK, since my script was being used in a local network for my own use. I would like to know the more surgical approach, like what firewall setting will allow my Linux platform to respond to the Pings without disabling the firewall all together. I am using Centos 6 and 7.
