It is worst! You need rights for RAW socket.
Similar situation is on Windows too, but Windows publish special API
for sending ping by non-admin users. Synapse can use it. But on Linux
I not know any special API.
Synapse documentation says:
Warning: For use of RAW sockets you must have some special rights on
some systems. So, it working allways when you have administator/root
rights. Otherwise you can have problems!
Thank you for the reply,
I do not fully understand the situation, I just move code from Kylix do
Lazarus and it stop to work, also i'm able to ping from user shell
command ... ?
The ping command is setuid root, so it executes as root:
ls -l /bin/ping
-rwsr-xr-x 1 root root 44168 May 7 2014 /bin/ping*
How it can work in kylix is beyond me, unless the kylix binary was setuid root
as well.
Michael.
