Setting source IP with posix sockets
Is it possible for an application to request a socket (tcp) and have it set the source address without using raw sockets? (the addresses would be bound to the interfaces. [no spoofing]).
This would be a tcp client connection, not bind()ing to a specified address.
Difference between a socket and a port
Could someone please explain quite clearly the difference between a port and a socket. I know that a port serves as a door into the network for an application
process and that the application process uses a socket connection to the given port number to handle network communication but when you have multiple processes listening on a single port number, I am finding it difficult to understand the difference between the socket and the port and how they all fit together.
Implementing the transport layer for a SIP UAC
I have a somewhat simple, but specific, question about implementing the transport layer for a SIP UAC.
What happens when an unexpected packet arrives at a computer? [closed]
It’s difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 11 years ago. I have been wondering this for a few […]
Sockets intricacies in TCP and UDP
I am quite familiar with TCP and UDP. I understand the process by which TCP establishes connections and other theoretical facts about TCP but when reading up about TCP hole punching for NAT Transversal, I have become stumped by how connect(), accept() and listen() is done in TCP. Is it a single or multiple sockets that are used for all this in TCP and is is this done the same way in UDP

Game Netplay Rollback System
Can one explain the specifics and details of a netplay framework for a game that optimizes connection through a “prediction / rollback” mechanic, as seen in games where speed is a priority (first-person shooters, modern fighting games since Street Fighter IV, etc)?
How can a server initiate request in SIP protocol?
Either a client or a server can initiate request in SIP. How is it possible? How will the server know about the client?
Theory about software communications mixing up with other software causing an Apocalypse?
I can remember a very Very long time ago (pre Y2K) , reading an article by some “expert” that theorized that software communicating over the internet, especially video games could get mixed up with Military communications meaning that a user could inadvertently mobilize a B52 nuclear bomber with a click of his mouse on a video game.
Server distribution for high performance
I’ve developed a Socket Application on top of TCP in .NET C#, which allows many clients to send files from one another via a VPS I’m using. Most file transfers will occur between people in the same region, say, even in the same neighborhood.
