Helps in determining TCP/IP networks IP address as well as determine issues with the network and assists in resolving them. See the ping definition for a full description.
Pings the localhost. which helps determine if the computer can send information out and receive the information back from itself.
Note: The above command does not send information over network, but can indicate if the card can respond .
Ping supports the ability to ping an Internet address. In the above example, we pinged "computerhope.com" and as can be seen, received four responses back. If we couldn't reach the server or the server was blocking our request we would have lost all four packets .
Allows you to ping another computer where <22.214.171.124> can be the IP address of the computer you want to ping. If you do not get a reply or get lost packets you have a problem with your network, which can be a cable issues, network card issues, drivers. router. switch. or other network problem.
I had this same issue on Win-7 machines with 6.1.1 packet tracer. I had to install Java 7.67 32-bit for the browser(IE 11-32-bit even though these are 64 bit boxes) and then uninstall and re-install packet tracer to get the psta player to work. Just installing 32-bit Java did not solve the problem out right. Java 7.65 had issues with running plugins. I had a lab of 30 machines to do this on. I assume 6.1 needs the 32-bit version of Java to run (7.65 or 8.25 32-bit would not work) and this corrupted the install because the psta player did not load. After installing the Java and re-installing PT 6.1 the ptsa player would load and run. You will be prompted to update Java-choose "later"-run and continue when prompted.
Access Point Name (APN) is a computer protocol that typically allows a user's computer to access the internet using the mobile phone network.
On a technical level it is a configurable network identifier used by a mobile device when connecting to a GSM carrier. The carrier will then examine this identifier to determine what type of network connection should be created, for example: what IP addresses should be assigned to the wireless device, what security methods should be used, and how/or if, it should be connected to some private customer network.
Note that "packet data" is the way that hand-held devices communicate over a cell-phone's network to pack an "envelope" around Internet data. So, talk to your cell-phone company about paying them a monthly fee to web-browse using your cell-phone.
You should specify what you mean by "identify what data is being downloaded."
If you are the techy-compu-geek type, then any simple "packet sniffing" program would work well for you. Just google "packet snniffer" and download one. Its mainly for the techy because most of the intercepted information would look like gibberish to the average user; it might most likely be in hex code.
if you are the average joe, then you can try a program like NetLimiter: http://www.netlimiter.com/. it "shows list of all applications communicating over network it's connections, transfer rates and more".
Note: even though you may not have any download programs running, there may be other services running on your computer that may check stuff online periodically.
If the netlimiter program finds a program with a name that you are not familiar with (as is most often the case), an easy way to see if its a virus or a legitimate service is by simply googling the name. Hope this works
I suggest the following: Install a packet analyzer to the target machine. This program helps you observe and analyze the network traffic real time. It is helpful for debug the network packets, look inside how the frames is structured. The Wireshark is quite popular debugger tool. Install it and check TCP/IP and SNMP packets with it. Here is it: http://www.wireshark.org/download.html
Second: There is a lot of information on the internet about the SNMP freame formats and TCP/IP protocol. Here are some useful links: http://www.tcpipguide.com/free/t_SNMPMessageFieldDefinitionsGeneralMessageFormatand.htm http://www.dpstele.com/layers/l2/snmp_l2_tut_part1.php http://www.rane.com/note161.html A lot of RFC documents write down the SNMP protocol.
Here are somple helpful VC++ programs: https://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=7949&lngWId=3
I suggest using free tools to test your network device: http://manageengine.adventnet.com/products/oputils/free-snmp-tools.html
Because of limited server and network capacities for streaming
applications, multimedia proxies are commonly used to cache multimedia
objects such that, by accessing nearby proxies, clients can enjoy a
smaller start-up latency and receive a better quality-of-service (QoS)
guarantee-for example, reduced packet loss and delay jitters for their
requests. However, the use of multimedia proxies increases the risk
that multimedia data are exposed to unauthorized access by intruders.
In this paper, we present a framework for implementing a secure
multimedia proxy system for audio and video streaming applications. The
framework employs a notion of asymmetric reversible parametric sequence
(ARPS) to provide the following security properties: i) data
confidentiality during transmission, ii) end-to-end data
confidentiality, iii) data confidentiality against proxy intruders, and
iv) data confidentiality against member collusion. Our framework is
grounded on a multikey RSA technique such that system resilience
against attacks is provably strong given standard computability
assumptions. One important feature of our proposed scheme is that
clients only need to perform a single decryption operation to recover
the original data even though the data packets may have been encrypted
by multiple proxies along the delivery path. We also propose the use of
a set of encryption configuration parameters (ECP) to trade off proxy
encryption throughput against the presentation quality of audio/video
obtained by unauthorized parties. Implementation results show that we
can simultaneously achieve high encryption throughput and extremely low
video quality (in terms of peak signal-to-noise ratio and visual
quality of decoded video frames) for unauthorized access.
