Best network sniffer / LAN analyzer

Looking for the latest & greatest, with functionality including (but not limited to):

- packet sniffing

- traffic analysis

- network utilization

- WiFi capability

- network diagrams (Visio integration)

Etc.. All the good stuff that we should have in order to really know how our networks are performing, identify bottlenecks and have the ability to troubleshoot them quickly on most common problems.

Any/all comments & recommendation will be much appreciated!

Cheers,

Al

Free would be Wireshark . For a paid one I would use Network Instruments Observer more feature rich and less costly than Network Generals sniffer.

Free is Wireshark no doubt. The paid version I've used and seemed to like is Network Instruments Observer.

Re: Best network sniffer / LAN analyzer

Free - Wireshark

Paid - Network General Sniffer (Now NETSCOUT)

Re: Best network sniffer / LAN analyzer

I have (and love) the Fluke Optiview. IT has copper GigE, Fiber GigE (SFP), and wireless. Ours is old enough to "just" have 802.11g, but they now have an 802.11N module.

In addition to the usual packet capture/decode, it has an expert (does a superficial analysis and finds common issues), does cable testing, TDR, and lots of other useful tools ... like crawling the subnets to find hosts, then doing an SNMP crawl to identify the devices and stats.

Plus it's relatively small, battery powered, remotely accessible ... lots of stuff.

It's also an excellent real-time network monitor, so it doesn't rot on the shelf between problems.

It does NOT do certification scans, but we have other equipment for that anyway.

FWIW

Agreed, WireShark and Observer are awesome. One new one we stumbled across lately was NetWitness. http://www.netwitness.com/

Hope this helps, rate if it does.
