They work almost the same as today. However, be sure you include [] around your IP. For example : http://[1fff:0:a88:85a3::ac1f]:8001/index.html Wikipedia has a pretty good article about IPv6: http://en.wikipedia.org/wiki/IPv6#Addressing
Just to note that nginx has now support for Websockets on the release 1.3.13. Example of use: location /websocket/ { proxy_pass ​http://backend_host; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection “upgrade”; proxy_read_timeout 86400; } You can also check the nginx changelog and the WebSocket proxying documentation.
TCP / HTTP Listening On Ports: How Can Many Users Share the Same Port So, what happens when a server listen for incoming connections on a TCP port? For example, let’s say you have a web-server on port 80. Let’s assume that your computer has the public IP address of 24.14.181.229 and the person that … Read more
As the others have said, you’ll have to kill all processes that are listening on that port. The easiest way to do that would be to use the fuser(1) command. For example, to see all of the processes listening for HTTP requests on port 80 (run as root or use sudo): # fuser 80/tcp If … Read more
When you send bytes from a buffer with a normal TCP socket, the send function returns the number of bytes of the buffer that were sent. If it is a non-blocking socket or a non-blocking send then the number of bytes sent may be less than the size of the buffer. If it is a … Read more
It’s easier to communicate via TCP sockets when you’re working within an intranet boundary, since you likely have control over the machines on that network and can open ports suitable for making the TCP connections. Over the internet, you’re communicating with someone else’s server on the other end. They are extremely unlikely to have any … Read more
Indeed, SCTP is used mostly in the telecom area. Traditionally, telecom switches use SS7 (Signaling System No. 7) to interconnect different entities in the telecom network. For example – the telecom provider’s subscriber data base(HLR), with a switch (MSC), the subscriber is connected too (MSC). The telecom area is moving to higher speeds and more … Read more
People say that the major thing TCP gives you is reliability. But that’s not really true. The most important thing TCP gives you is congestion control: you can run 100 TCP connections across a DSL link all going at max speed, and all 100 connections will be productive, because they all “sense” the available bandwidth. … Read more
This exception means that there is no service listening on the IP/port you are trying to connect to: You are trying to connect to the wrong IP/Host or port. You have not started your server. Your server is not listening for connections. On Windows servers, the listen backlog queue is full.
The absolute limitation on TCP packet size is 64K (65535 bytes), but in practicality this is far larger than the size of any packet you will see, because the lower layers (e.g. ethernet) have lower packet sizes. The MTU (Maximum Transmission Unit) for Ethernet, for instance, is 1500 bytes. Some types of networks (like Token … Read more
