It's software on a PC, or a handheld device that listens to the network traffic and displays the network traffic.  It usually knows about a large number of different protocols and can show the meaning of the different packets.\n\nFor example, the software listed below understands ethernet, TCP and http.  If you view a web page while the software is capturing, it will show the TCP SYN/ACK, the http get and the http response.

The best tool for this sort of thing is a command line tool called Nmap (http://www.insecure.org). One of the great things about Nmap is that it runs on Windows and just about any UNIX/Linux distribution you care to mention. I've used it for years, and the new versions just keep getting better and better. Now, in addition to performing port scanning and OS fingerprinting, it can also perform service fingerprinting. For example, instead of just saying that port 80 is open and that it is likely a web server, it will tell you that port 80 is open and the person is running Apache 2.0.12 or something along those lines. Great tool. Seriously, this is one of those tools that I *must* have on all of my computers. Absolutely invaluable.

SMTP\n(Simple Mail Transfer Protocol) is used for transportation of email from one host to another. The protocol was designed with openess in mind such that there is no security in verifying the sender. It also avoids traffic by allowing multiple receipients with only one copy of the data being sent from one host to another. \nPOP3\n(Post Office Protocol 3) is the protocol that allows email retrieval and deletion/undelete. \nIMAP\n(Interner Message Access Protocol, version 4rev1) is another protocol that handles email retrieval, but with increased manipulation capability. IMAP allows the manipulation of remote messages mailboxes, very much as if these mailboxes were accessed locally. IMAP's functionality includes creation, deletion, and the renaming of mailboxes, and the checking and setting of email messages statuses (FLAGS). The messages themselves can be partially retrieved and searched given various parameters.

RIP is limited ti 15 hops and OSPF is not.\nOSPF calcualte the best path by many parameters like bandwidth, delay etc.  whereas RIP works only on hop counting.

The URL i've given below is very important . it is for the REQUEST FOR COMMENTS...page & u have to go to this url & using ur browsers " Find " option in " Edit" menu search for whatever computer terms u need..& u can download the RFC in different formats..\n\nhttp://www.rfc-editor.org/rfc-index2.html\n\nthis URL may be useful for all the computer users..\n\nu may find the RFCs related to ur needs..

You can use software such as:\n\n1. Your own web log. Ask your webhost to give you access to your web log -- you'll see the IP address, what pages they are accessing and their source traffic in real time\n\n2. Use softwares such as\n\nHBX http://www.websidestory.com/\nGoogle Analytics http://www.google.com/analytics/ (free)\nWebTrends http://www.webtrends.com/

In order to find something like this, I would recommend that you download HiJackThis Software. The program scans your PC and creates a Log of all the processes and programs that are running on your PC at the current moment. If you don't know how to analyze this Log, I suggest that you go to http://www.savemybutt.com/ site and download the free software and learn how to use it as well, and post your Log here\nhttp://www.savemybutt.com/forums/index.php?board=13.0\nThis is a Chicago-based forum that offers free help to those who need help reading their HiJackThis Logs.

A routing protocol which uses routing algorithms helps a router to send data packets to correct destination. When you write www.yahoo.com to the address bar of your browser and press enter, you make a request to yahoo.com but where the hell is that yahoo machine? \n\nFirst a DNS resolution occurs and your Internet Explorer learns yahoo machine's IP. Then send datas to the IP number. But then again how IP packets (data packets) find their way to yahoo? There must be some traffic polices - we call routers - that sends these data packets between themselves finally to destination. They are like stepping stones accross a river but there are lots of these stones and packets must cross the river via the shortest path to the otherside. So policemen - or stones - must know the next stone location on the path. \n\nFinally comes the routing protocols and their algorithms...  Routing protocols reveal routers (policeman, stepping stones, you name it), which way to the destination (the otherside of the river). To be precise which router is the next route to the destination, so that packets hopping one router to the other to be lasted on the destination : yahoo.com. Routing protocols uses some algorithms to make these decisions, and (at last) these algorithms are the ones you ask.\n\nBut you must not mix routing protocols with the routed protocols. The sending of the actual data is done by routed protocols, but the learning of the way by router done via routing protocols... \n\nPopuler Routing Protocols : RIP, IGRP, BGP, OSPF (Open Shortest Path First, not "Obtain")\nPopuler Routed Protocols : IP, IPX\n\nI hope the links I gave helps.\nCheers.

All network traffic is subject to scrutiny in a network, admin or not. A simple packet sniffer program can show all traffic for the entire subnet, even from another client.

First, you can look for addresses (email/IP) using any hex editor. But it can be hidden.\nThe best way is to use packet grabber and to save all keylogger internet activity. Note that it can take a long time: maybe, your keylogger reports only once a week. So you packet capturing filter must be tricky.

I have have setup networks for LAN and WAN activites. I have programmed routers from Cisco to Netgear.  Automatic Network Analyser is not a main term used to describe a special type of  software. Understand there are all kinds of software that help manage, create, and troubleshoot your network. \n\nSo you will need to post the name of the software you are using.

Not enough information to tell. But put ethereal on one of them and check out the packets and see which ones are doing what.

HyperText Transfer Protocol.\n\nThis is the protocol which powers the Web. Your web browser is an HTTP client; sites you connect to run HTTP servers.\n\nEdit: Some of the answers below illustrate why you shouldn't trust Yahoo! Answers at face value. For example, HTTP does NOT indicate that the site is secure -- the poster was thinking of HTTPS (the S stands for secure.)
