Looking for Network Analyzer

Does anyone know of an updated application, preferably free, that analyzes and reports all internet traffic?

I've had no luck finding anything good, was hoping maybe someone here may know of one that does the job quite well.

 

I use the free edition of athtek netwalk.aANot sure if your looking for something more?

Wireshark is an option.

 

Comodo Firewall.

 

How so.?

 

This looks like an interesting tool, does it alert you of suspicious activities?

 

I've heard about this one before, I'm going to test this one out...thank you

 

Wireshark is a good tool, but isn't it more for packet sniffing than network analyze software?

 

SoftPerfect Network Protocol Analyzer is a good choice if Wireshark proves to be a bit too complicated.

 

Thank you, I'll take a look at it.

 

You can take a look here, but no info on how up-to-date they are.

 

Thank you for this link. Very useful.

 

SysInternals TCPView is a no brainer: http://technet.microsoft.com/en-us/sysinternals/bb897437.aspx Only checks TCP and UDP endpoints.

NirSoft's CurrPorts is similiar to TCPView but with options. This one will show you what services being used by svchost.exe.http://www.nirsoft.net/utils/cports.html

 

It monitors all traffic in and out of a network card. It allows you to get granular and look at packets.

There is also LayerView.

 

The only problem with wireshark is that it doesnt run in realtime but gives you a picture of packets at the time of the snapshot.If anything non-legit is calling home on your computer then its hit and miss if wireshark would capture this.

Anyhow its the job of the firewall to stop non legit outbound connections.Although for the curious wireshark is a great tool.

 

Wireshark has the ability to capture traffic in real time.

 

Thanks whitedragon.
Long time since i used it and was not aware it was capable of this.

 

Last time I used it was when I managed a BF2 server. We used it to capture packets and catch people using hack tools. The server would get laggy when someone was trying to cheat and the packet size would double compared to a normal size packet from someone who wasnt cheating. Made it very easy to ban hackers.
