From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
Rules
- Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.
- No misinformation

Wireshark
One strategy is to block everything, and open ports as needed. Beware that most guides focus on inbound traffic, whereas you seem to be focusing on outbound traffic.
Why are we recommending Wireshark? That doesn't make any sense what so ever. If anything have them run a port scan with nmap.
This is crazy advise
wireshark does not work for individual apps, it cannot make a difference between traffic of process a and b.
I'm not sure how Wireshark is related to firewalls honestly. It is mostly a layer 1 and 2 tool
