Sir I got your point regarding the security as it depends on wired or wireless network or further the internal network design of an organisation and the WEP/WPA security of their network.
When we install WIRESHARK or most of the softwares on any distro, window prompts up asking for root password. When the installation of the software starts, can't we run a script which will allow the logged in user or third-party user to view the listed interfaces of the system. I want to ask that "If I will study all installation criteria and changes it makes to the other folders and files, am I proceeding in right direction?". Thanks!
