Server port

Solves Objective: Find out what port the server was hosted on

What is this task?

All this task is asking us to do is find the port the server is by default configured to connect to. Quite simple especially if you already checked the page below.

Methodologies and Theory

Solving this task

In order to solve this task, we can analyze the htons() function in the server and the routine then verify its location and pick apart the arguments pushed before calling the function.

Note that we already knew htons was called as we looked at it in the import table when Locating The Server Routine

Step 1 - Locate and Analyze

The first step to this is to first go to the first location in which htons is being called. That so happens to be the location shown below.

Thankfully enough, this is actually exactly where we need to be. This entire screenshot captures our answer and proof that this is the right answer.

Step 2 - Summary

The answer to this is 8080 by default configuration. This is because when we analyze the htons argument, not only do we see the only occurrence of bind() being used for the same exact configuration that also utilizes the htons function but we also know that the argument pushed to htons is 0x1F90 and that in decimal is 8080.
