Relevant Port Assignments

---

It is usually better to go with the standard ports, which as we know are listed in /etc/services. Rather than having everyone search through the 2090 lines of assignments there, here is a list of relevant ports for the Lab Exercises

A more extensive (and colorful!) list of commonly used ports is here

# The Well Known Ports are those from 0 through 1023.
# The Registered Ports are those from 1024 through 49151
# The Dynamic and/or Private Ports are those from 49152 through 65535
