Analysing Wireshark output


Hi

This is the first time I've used Wireshark, I also know nothing about networks and packets, so don't expect too much ! We have a Dell Vostro 1700 and the online led is flash almost continually, even with nothing open. Apart from some obvious NTP packets, the following is a regularly repeated sequence, every few seconds. Can anyone please suggest what might be causing it and how it can be prevented?


1 0.000000000 192.168.0.1 255.255.255.255 UDP 215 Source port: 33004 Destination port: 7423

Frame 1: 215 bytes on wire (1720 bits), 215 bytes captured (1720 bits) on interface 0
Ethernet II, Src: Netgear_fb:f8:4e (9c:d3:6d:fb:f8:4e), Dst: Broadcast (ff:ff:ff:ff:ff:ff)
Internet Protocol Version 4, Src: 192.168.0.1 (192.168.0.1), Dst: 255.255.255.255 (255.255.255.255)
User Datagram Protocol, Src Port: 33004 (33004), Dst Port: 7423 (7423)
Data (173 bytes)


TIA

First hunch: NetGear ReadyShare. Fix: upgrade router firmware. If not available you're SOL unless you can make the vendor release one.

The router's a Netgear DGND3700v2 and certainly has Readyshare.
The software is up to date, so nothing can be done there.
If you're right, I guess I'm SOL as you say !

Well, saying SOL may be a bit harsh. As long as its advertisements don't cross network boundaries (and unless you severely mangled your firewall it shouldn't by default) all that remains is just a chatty service...
