has anyone ever used a network scanner called packet analyzer?
545353
Packet sniffers (also known as network or protocol analyzers or Ethernet sniffers) are computer software (usually) or computer hardware that can intercept and log traffic passing over a digital network or part of a network. As data streams travel back and forth over the network, the sniffer captures each packet and eventually decodes and analyzes its content according to the appropriate RFC or other specifications. Depending on the network structure (hub or switch) one can sniff all or just parts of the traffic from a single machine within the network; however, there are some methods to avoid traffic narrowing by switches to gain access to traffic from other systems on the network (e.g. ARP spoofing). For network monitoring purposes it may also be desirable to monitor all data packets in a LAN by using a network switch with a so-called monitoring port (it mirrors all packets passing through all ports of the switch).\n\nThe special network device driver used for some packet sniffing software is said to operate in "promiscuous mode" as it listens to everything on the wire.\n\nThe versatility of packet sniffers means they can be used to:\n\nAnalyse network problems. \nDetect network intrusion attempts. \nGain information for effecting a network intrusion. \nMonitor network usage. \nGather and report network statistics. \nFilter suspect content from network traffic. \nSpy on other network users and collect sensitive information such as passwords (depending on any content encryption methods which may be in use) \nReverse engineer protocols used over the network. \nDebug client/server communications.

Go to speedguide and use there tcp/ip analyzer/optimizer to see where the problems in your system are at

it's a network security tool designed to detect malicious activity\n\nhttp://en.wikipedia.org/wiki/Packet_sniffer

Almost all wireless routers have a utility screen that allows you to "see" the wireless connections that are present. You can always ping your networks broadcast address to invoke activity from all "listening" devices, and then check the computer arp table to see a list of devices.

There are two that i know of:\nAvast! and AVG Free. \nThese two do both and scan web pages, e-mail, and IM.

Now even if there were software, how do you expect your computer to pick up a signal? That is what a scanner is for.

I seen one at CompUSA, but I don't know about nd software.\nI assume you are reading and not creating fingerprints.

You can do many things for this.  There are a lot of free/shareware/and programs for sale that do this exact thing.  otherwise you can DIY rather simply.  Go to start, run and type in cmd to get the command prompt (its also under all programs)  then type tracert (trace route) this will allow you to trace ever address that your network runs through basically by sending out a ping that bounces off the network addresses and returns the info.  You have to supply a target address for this to work properly.

If you log into your router, you can look at the lan configuration and see what computers are using the network, but if you are using WEP encryption, it should not be an issue anyway.

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.

Log into the Router, then look at the LOG file.  This will probably be a dead give-away.

Spybot is great.  If you are willing to try Microsoft's beta, consider defender.  Both are currently free.\n\nhttp://www.safer-networking.org/\nhttp://www.microsoft.com/downloads/details.aspx?FamilyID=435bfce7-da2b-4a6a-afa4-f7f14e605a0d&DisplayLang=en
