Wireshark-users: Re: [Wireshark-users] Looking for a portable sniffing-friendlyhub/switch
One difference between the $1K tap and the DIY version might be that
the expensive one will work wherever you put it in your network.
The DIY version instructions to
Strip the cat 5 cable and untwist all the individual wires.
I believe makes it not cat 5 any more. It's probably still good
enough for it's intended purpose - ie. at home & cheap - but maybe not
such a great idea to use on a critical link at work. (which isn't
going to stop me from trying to make one myself :)
Thanks for the link to the DIY taps - I hadn't seen those before.
Regards,
Lee
