Hy All,
When I use icmp in my c code it works fine.
As I moved it into antother computer I received nothing back. Or I received back echo messages if I started a "ping "something"" command from the consol. During the ping command was running my code was working fine.
I thought it is because of the firewall, but it is not probably.
I use own socket and create ip and icmp packeges. What is the common point in case of ping and in my application? What does ping set what I did not?
Do you have any idea?
