Network BIND - how it works - help, details needed
by zeebra from LinuxQuestions.org on (#5NNEV)
I've been trying to figure out the details, but I can't, and I can't understand the few things I did find, I'm not network savvy. I was hoping someone could explain it in layman terms.
So, there are calls "send" "connect" "listen" and "bind" for different functions in the Linux network stack. The other ones seems clear enough, but what is the role of "bind", and how exactly does it work? What does it do? What role does it play in network input/output between the local host and https://foo.bar
Who request network binds and why? And in the context of firewalling and security, how does this affect security? From what I can see, blocking all inet bind requests does not prevent anything from working online. I'm running a firewall, so what would be the difference for the firewall if I block all bind requests(elsewhere) or don't?
Are network binds transparent in the context of firewall and security?
I'm hoping someone knowledgeable on this topic could enlighten me. Thanks in advance!
