On my linux machine, 1 of 3 network interfaces may be actually connected to the internet. I need to get the IP address of the currently connected interface, keeping in mind that my other 2 interfaces may be assigned IP addresses, just not be connected. I can just ping a website through each of my interfaces to determine which one has co...
In Linux, after establishing a DHCP lease, when I run the command route, the last line gives me the system's default route and NIC. e.g., Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use IFace 142.157.138.0 * 255.255.254.0 U 2 0 0 wlan0 link-local * ...
We are building a new vision inspection system application. The actual inspection system needs to be c++ for a number of reasons. For that system we will be using Boost & Qt. For our UI, we are currently looking at using WPF/C# for the UI and SQL based reports. The complicating factor that UI has to run both local on the same box as ...
I'm creating a client-server application which communicates via a custom socket protocol. I'd like the client to be usable from within networks that have a restrictive firewall (corporate, school, etc.). Usually this is done by connecting via HTTP, since that's always available. If I want to do that, do I really have to use HTTP or is i...
I'm stumped as to why one of my computers gets TERRIBLE broadband speeds late at night, and is OK in the morning. I checked for a scheduled backup or drive scan. There are none. Speedtest.net shows 1.1 MBpersec down and no upload at all. This typically starts at about 11:30pm and goes into the early morning hours. By 9am it is back to ...
I didn't think this was possible, but mIRC can get the name of a network, even if it is not specified by the user in the server list. I tried using a packet sniffer to see if perhaps there was a message sent on connect that sends the network's name, but I didn't see anything. The network name is needed to display to the user as well as ...
I was just wondering where I could find a article on sockets. I don't want any indepth code. I just want to understand the structures and other stuff like the how the buffers work. ...
I recently installed windows 7. As a part of this, I was required to install the drivers for my onboard wireless adapter (Realtek 8187). However, with the driver came this annoying management studio called Realtek Wireless Lan Utility. It's not a huge burden, except that every time I log in to my computer (if I've been idle for a whil...

How to connect to remote udp multicast if I have an IP address where the service resided (say 70.70.70.70), the multicast group to connect (say 224.25.25.25) and port (say 2020)? I use ACE framework and in the sniffer I see that ACE sends IGMP packet to 224.0.0.2, in order to join a group, but my home router (checkpoint) doesn't know wh...
Hello, I need to configure my ZTE ZVE10 W300 router as a proxy server. I need the users connect to router (with real ip) and use internet through it. Is there any way to do it ? I dont want to setup web proxy server or something else behind the router, but want to do that exactly on the router. Regards, Levon ...
I would like to simulate packets reordering for UDP packets on Linux to measure the performance and fault tolerance of my application. Is there a simple way to do this? ...
I want to capture packets whoes has a special target ip, then forward these packets by UDP. Does Ruby can do this ? thanks ...
A router exposes itself to outside by IP like 66.249.89.104 and many hosts can connect to it to form a Local Area Network. My question : Is there a way to identify a specific host in that LAN? All I tried is some guessing work which fails with no doubt: ping [email protected] Ping request could not find host [email protected]...

Hi, maybe this is a noob question, but I'm receiving some data over TCP and when I look at the string I get the following: \x00\r\xeb\x00\x00\x00\x00\x01t\x00 What is that \r character, and what does the t in \x01t mean? I've tried Googling, but I'm not sure what to Google for... thanks. ...
I have an application that spiders websites for information. It seems like after 20-45 minutes of creating HttpWebRequests a bunch of them return timeouts. One thing we do is attach a BindIPDelegate anonymous function to give the request a specific IP since we round-robin through about 150 IPs. I'm setting up the HttpWebRequest object...
I think there is no way to enumerate each network interface on my system and their assigned IP using just sockets, is this correct? I mean, in linux this could be: eth0: 192.168.1.5 wlan0: 192.168.0.5 lo: 127.0.0.1 I dont care interface names, just the IPs assigned. I recall to have done this in the past in Windows, using winapi (tho...
