Wireshark · Ethereal-users: Re: [Ethereal-users] How to sniff packets between two local ports using Ethereal?

[Scott Lowrey <slowrey@xxxxxxxxxxx>]

Depending on the OS you are using, the kernel is probably smart enough to route these packets directly between the two applications without handing them down to the Ethernet device driver (and out onto the wire).

However, you might trying capturing on the loopback device.

Hello,

I am using Ethereal Packet Analyzer to capturing packets that are being exchanged between two applications running on two different ports(say 10000 and 13000) but on the same machine.

Is there any way to sniff these packets using Ethereal. However, we are able to capture packets exchange between applications running on two different machines but unable to capture in the aforesaid scenario.

Please guide us the way to use/customize Ethereal for such scenario.

Thanks and regards,
