I'm talking about http://en.wikipedia.org/wiki/Quality_of_service . With streaming stackoverflow podcasts and downloading the lastest updates to ubuntu, I would like to have QoS working so I can use stackoverflow without my http connections timing out or taking forever. I'm using an iConnect …

What I'm doing wrong that I get the ADMA5026E error when deployment an application with the NetworkDeployment Console?

I would like to set up VPN access for people in my company to use when they are working from home and on the road. We have a VPN service built into our Watchgard firewall, but it requires a Windows-only custom client and some of our employees have Macs or Linux computers. I am not any sort of n…

One major problem I have is corporate IT policy (Oh, I'm not alone then? :) ) Specifically that if I'm off-site using a VPN connection, I cannot link to anything outside that VPN connection. So my local printer at home is off-limits unless I disconnect - a simplistic example of the hampering…

In a C++ Windows (XP and NT, if it makes a difference) application I'm working on, I need to get the network name associated with the computer the code is executing on, so that I can convert local filenames from C:\filename.ext to \\network_name\C$\filename.ext. How would I do this? Alternative…

Let's say I have a drive such as "C:\", and I want to find out if it's shared and what it's share name (e.g. "C$") is. To find out if it's shared, I can use NetShareCheck . How do I then map the drive to its share name? I thought that NetShareGetInfo would do it, but it looks like that takes…

How do you use network sockets in Pascal?

I know this is not programming directly, but it's regarding a development workstation I'm setting up...so bare with me. I've got a Windows Server 2003 machine that needs to be on two LAN segments at the same time. One of them is a 10.17.x.x LAN and the other is 10.16.x.x The problem is that …

Some things look strange to me: What is the distinction between 0.0.0.0, 127.0.0.1, and [::]? How should each part of the foreign address be read (part1:part2)? What does a state Time Wait, Close Wait mean? etc. Could someone give a quick overview of how to interpret these results?…

I have a client/server application that communicates with .Net remoting. I need my clients to be able to find the server(s) on the network without requiring client-side configuration. As far as I know, there is no support for discovery in remoting. I am prepared to implement a UDP solution wher…

I have a listening port on my server that I'm connecting to using a Java class and the Socket interface, i.e. Socket mySocket = new Socket(host,port); I then grab an OutputStream, decorate with a PrintWriter in autoflush mode and I'm laughing - except if the listening port closes. Then I ge…

Besides "no connection", what other failure modes should I test for? How do I simulate a high-latency link, an unreliable link, or all the other sorts of crazy stuff that will undoubtedly happen "in the wild"? How about wireless applications--how do I test the performance in a less-than-ideal WL e…

After reading a bit more about how Gnutella and other P2P networks function, I wanted to start my own peer-to-peer system. I went in thinking that I would find plenty of tutorials and language-agnostic guidelines which could be applied, however I was met with a vague simplistic overview. I coul…

How do you get the maximum number of bytes that can be passed to a sendto(..) call for a socket opened as a UDP port?
