How to install Filder on Ubuntu 11.10 ? Or can someone suggest me other software, I need to monitor TCP from just one IP address.

When you say "Filder", do you mean "Fiddler2"? – RedGrittyBrick Oct 26 '11 at 9:22

To monitor TCP packets arriving at my computer from one source address I would use tcpdump

 tcpdump host foo

To view HTTP requests and responses I would prefer to use Wireshark's "follow tcp stream" feature. You can probably install it using apt-get wireshark or by using Synaptic

Wireshark is useful, but for day-to-day HTTP debugging, I find it too low-level. – Piskvor Oct 26 '11 at 9:48

You can't, really. What I did was to install Virtualbox, and make a WinXP virtual machine in it. I run Fiddler there, and connect to it as to a normal proxy, from the host computer. This has the extra requirement of a Windows license, but It Works.
