How to assign incoming packet's source port to outgoing packet destination port — TCP C Linux

问题 I like to know the source port of packet in tcphdr can be assigned to destination port of ip like this source_ip_tcph->source= dest_ip_tcph->dest; source_ip_tcph->dest = dest_ip_tcph->source; above are source and destination (pointer to memory) of tcphdr type I am trying to create a server everytime I respond to client from server the destination port is different. I assigned it like above Edit Above I am using raw sockets. trying to make raw socket based tcp implementation as a server 来源：

Is Serialization the best for sending data over a socket?

由 邮差的信 提交于 2021-01-05 06:19:23
问题 Someone told me That Serialization was not the best way to send things over a socket but they said they read that in a book once and was not sure of a better way cause they haven't really done networking before. so is Serialization the best way or is there a better way. Also this is for a game if that makes much of a difference. What i see by searching questions about sending objects over it looks like most people use Serialization but im just checking to see what people thing 回答1: To

Can nginx do TCP load balance with SSL termination

由 给你一囗甜甜゛ 提交于 2020-12-29 04:43:09
问题 Due to some reason, I need to set up nginx tcp load balance, but with ssl termination. I am not sure whether Nginx can do this. Since tcp is layer 4, ssl is layer 5, SSL pass-thru definitely work. But with SSL-termination? Thanks for suggestions. 回答1: Nginx can act as L3/4 balancer with stream module: https://www.nginx.com/resources/admin-guide/tcp-load-balancing/ Because SSL still tcp - Nginx can proxy SSL traffic without termination. Also stream module can terminate SSL traffic, but it's

TCP Fast Open: expediting web services

由 安稳与你 提交于 2020-12-26 09:21:13
Much of today's Internet traffic takes the form of short TCP data flows that consist of just a few round trips exchanging data segments before the connection is terminated. The prototypical example of this kind of short TCP conversation is the transfer of web pages over the Hypertext Transfer Protocol (HTTP). The speed of TCP data flows is dependent on two factors: transmission delay (the width of the data pipe) and propagation delay (the time that the data takes to travel from one end of the pipe to the other). Transmission delay is dependent on network bandwidth, which has increased steadily
