Feb 9, 2011I developed a protocol "it's a modification of OLSR" for wireless networks, it was with JAVA and I try to simulate it on NS2, I used AgentJ, so in the TCL I did any thing like usual;
set val(chan) Channel/WirelessChannel ;# channel type
set val(prop)Propagation/TwoRayGround ;# radio-propagation model
set val(netif) Phy/WirelessPhy ;# network interface type
[code]....
and I didn't specified the protocol because I attached my nodes to the JAVA class responsible for the protocol, but when I run it generates errors, it claims the protocol to use, so I don't know how proceeding.
Programming :: Regarding Query Protocol On Internet?
Jul 17, 2011There is a protocol in use - for example when I use Firefox to do a query through Google - as I type into the search field the browser sends my characters - one at a time - to the server. As I recall, at one time I found the specification but I'm pulling a blank. As I recall it does a POST of each character as I enter it, and the server responds before I have entered a <CR>. I want to write a client side program that uses that protocol and need to see the spec.

Extracting the above code into a test program, both return success.2. Placing the above code into the 1st line of my app, error as above.3. I ran app and test program in the same terminal window.4. My app links in many static libraries 5. My app runs fine when compiled and linked on RHEL56. My APP is a ss7 endpoint (SIP <==> SS7 message flow)7. I verified PF_INET, SOCK_STREAM, SOCK_SGRAM values are correct.

Programming :: Simulate A Serial Protocol In User Space Program To Test Reception Algorithm?
Jul 28, 2010I want to simulate a serial protocol in user space program to test reception algorithm. The protocol is similar to UART protocol but frame format is different. The duration of 1 bit is 114,46 us. In my main function I'm creating two threads. Tx for simulating transmitting data and Rx for reception data. For measure time I use create_timer() function and signals. Each thread has its own timer and signal handler. Tx timer uses SIGUSR1 and Rx timer uses SIGUSR2. Tx thread sets the global variable and Rx reads it.
The timers are set to sample with 114,46 us period. When they reach this value signal handler should set the flag. Flag is check in thread and some operation are made. When I set the timers period for longer time (100 ms) everything works fine but when I change it to default value (114,46 us) the Rx thread doesn't receive the proper data. I am wondering if the 114,46 timer period is possible to simulate in user space? Whether the time will give me the proper resolution ? Theoretically it should provide 1 ns resolution.
Programming :: Socket Programming Select Interface
Jan 15, 2010I have currently had the need to go back to basic socket programming, and implemented a simple udp packet sender. But I realized I needed to be able to select which network interface to send the packets from.
The reason is so that one of the interfaces has vlan tagging, and I need my UDP packets to be accordingly vlan tagged. For example, one of the interfaces is eth1.200.

Apr 18, 2011this is my first time here: I've been programming GUI software in C# in MonoDev for some time now. I just noticed that I can use my favorite language, C, with Glade to do the same thing. I've been going through some tutorials with a little frustration with them. Some seem to be written for older Glade versions.
The latest example had me save my Glade project to a "tutorial.glade" file. Then run it through a 'gtk-builder-convert' utility. Problem: the utility program returns errors indicating the the tutorial.glade file was written badly, that there is supposed to be a <glade-interface> tag that is missing.

Programming :: Ways Of Handling The ADT Interface?
Nov 30, 2010During my read, "Code Complete",the author described the different ways of handling the ADT interface.He has wrote this passage:
Quote:
Option 2: Explicitly provide the data used by the ADT services. In this approach, you declare the data that the ADT uses within each routine that uses an ADT service. In other words, you create a Font data type that you pass to each of the ADT service routines. You must design the ADT service routines so that they use the Font data that's passed to them each time they're called. The client code doesn't need a font ID if you use this approach because it keeps track of the font data itself. (Even though the data is available directly from the Font data type, you should access it only with the ADT service routines.This is called keeping the structure "closed.") The advantage of this approach is that the ADT service routines don't have to look up font information based on a font ID. The disadvantage is that it exposes font data to the rest of the program, which increases the likelihood that client code will make use of the
ADT's implementation details that should have remained hidden within the ADT.
The problem is that it is a bit subtle in terms of coding for me. Can anybody give more concrete example, in working codes, especially in Java?
Programming :: Running Iperf On Machine From Web Interface
May 22, 2011I'm not sure if I'm posting in the correct section, so please move it if it isn't.I currently have a bunch of laptops for testing a distributed network - throughput etc., using a bunch of bash scripts that send or listen to multiple addresses and ports, which run iperf. But at the moment I have to run it from each machine, or log in through ssh.To make this easier, I'd like to be able to present a bunch of buttons and selections from a web interface, so I can just put in the hostname of each laptop, and then click on a presented 'send' or 'listen' button to then execute iperf, and be able to kill it early if need by, say, by a 'stop' button.
What is the best way to go about this? Python, JavaScript, Java Servlet?And how would I do it? Just one of the above on Apache or something on each laptop?I just don't which direction to start heading in. Any help would be greatly appreciated.BTW. The network is considered to be not connected to the Internet, so I'm not too concerned about security, but if you've got any suggestion of how to start and stop iperf securely from a web interface on a machine, I'm interested.

View 1 Replies View RelatedProgramming :: Injecting Raw Ethernet Frames Using TAP Interface?
Apr 26, 2010I have UDP packets generated on Machine A that are addressed to Machine B (unicast) that I capture with PCAP. After transporting this raw data to Machine B (via RF modem) I'm trying to reinject the original UDP on Machine B through a tap0 interface. The capture and transport are all working fine. BUT once on the destination machine, the reinjected ethernet packets are NOT being received by a local UDP server. this is my socket creation :
Code:
outputSocket = socket(AF_PACKET, SOCK_RAW, htons(ETH_P_ALL));
struct ifreq s_ifr;
strcpy(s_ifr.ifr_name, "tap0");
"data" is an unsigned char array that contains the original packet data received from pcap, which includes the ethernet header, ip header, udp header, and payload data. after the call to write() completes, Wireshark on Machine B sees a correctly formatted (checksums and all) UDP packet when listening to tap0 - ie. no lines highlighted in red. *BUT* - a UDP server i have running on Machine B never receives the reinjected UDP datagram. (I have verified that this server works, by using a simple local udp generator app.) is there something wrong with how I'm creating the socket and/or writing the data back out to the tap0?

So whether i can open this file and use stat call to identify whether the size is 0. If size is 0, i can assume no USB present. Else i can assume USB is present.
Whether my understanding correct. If USB inserted, how can i check the folders present in the USB stick.
Programming :: Use Firefox As User-interface For Shell Script?
Mar 29, 2010In Windows, I was able to use IE as a user interface because I could code a WSF (Windows equivalent to shell script) to respond to events in IE.Now that I've moved to Linux/Firefox, I'd like to use Firefox in a similar way. Specifically, I would like to write a bash script to run lsdvd with XML output, use XSL to transform the XML for Firefox, then take an action (encode a selected track on the DVD) based on the user's selection. I would be happy if I could make Firefox write something somewhere that the script could read, but I suspect that security measures would prevent that.
