Hi, I'm trying to build a DNS server in python. It must listen two ports (8007 - client, 8008 - admin). The client only send an URL and receives the respective IP. The admin has permissions to change the DNS table (add, remove,.. doesn't matter to this right now). So my question is: how do I implement the server listening continuously ...
Which of the following ports is the best one to use for a program I'm working on using a custom protocol still under development. I'm looking for one that will be accessible to virtually every host that is connected to the public internet (ie every host that can view websites can use this port). The three main options are: port 53 udp ...
this is the code that i get so far... import java.net.*; public class PortScanner { public static void main(String args[]) { int startPortRange = 0; int stopPortRange = 0; startPortRange = Integer.parseInt(args[0]); stopPortRange = Integer.parseInt(args[1]); for (int i = startPortRange; i <= stopPortRang...
I apologize for the weird question wording... here's the design problem: I am developing a server (on Linux using C++, FWIW) that provides a service to many instances of a client application running on consumer PCs. I want the following: 1) All clients first identify themselves to a "gatekeeper" server application. Consider this a lo...

Hi, Why does the client end of a connection use high port number(ephemeral ports) whereas the applications listen on typically small port numbers ? Thx in advans, Karthik Balaguru ...
Assuming infinite performance from hardware, can a Linux box support >65536 open TCP connections? I understand that the number of ephemeral ports (<65536) limits the number of connections from one local IP to one port on one remote IP. The tuple (local ip, local port, remote ip, remote port) is what uniquely defines a TCP connection; d...
Hello, everyone! What is the common way in Java to validate and convert a string of the form host:port into an instance of InetSocketAddress? It would be nice if following criteria were met: No address lookups; Working for IPv4, IPv6, and "string" hostnames; (For IPv4 it's ip:port, for IPv6 it's [ip]:port, right? Is there some RFC wh...
I am trying to find out if there are any relevant measurements that LoadRunner can track, when running a load test - where it can allow me to monitor the number of active outbound ports from a given windows 2003 box. i am seeing that there are various measurements specific to CLR and IIS - such as current connections, but i am looking ...
i am using MaxUserPort setting (with 65000 as its value) in the registry on one of my servers (windows 2003 server). this was done to enable the box to handle a certain load profile. the setting has been working fine, along with the TcpTimedWaitDelay setting set at 30. i have setup the same settings on another windows 2003 server box, ...
I'm making server that make a tcp socket and work over port range, with each port it will listen on that port for some time, then continue the rest of the code. like this:: import socket sck = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sck.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) msg ='' ports = [x for x in xrange...
I'm now learning Ruby because I saw it's a very powerfull language, but now I want to know what mobile ports of Ruby we have and for what devices. PS: I have a HTC S711, HP iPAQ Hx2, Nokia E61, Nokia N95, Palm T|X, Palm Z22, HP Jornada 720..., it's better if I can use it on these platforms, but I'm open to buy other devices, as I'm a mo...

Hi I have Mac OS 10.6.3, python 2.6, mac ports 1.8.2. Im trying to run 'sudo port install py26-gtk' but my mac book doesn't get further than 'building gcc43', while doing that it switches off without shutting down. It is not overheating since I tried it again while my mac book was sandwiched between 2 cold packs. The mac was cool and t...
I'm researching remote control testing for an app that'll be installed on the new iPod Touch and can't tell for certain from everything that I've read whether or not an installed app can or can't open any ports for remote test instructions (that's a mouthful : ) We created something like this for the Android using adb port forwarding an...

Hey SO Doing a some practice questions for exam tomorrow can't figure out this one What is the minimum number of socket port(s) required for a TCP server to connect a TCP client for communication? Surely its just two right? one for the server one for the client, but this seems to obvious. My mates thinks TCP uses two ports at the ser...
