 You can't.

I'm wondering why iptables logging and dropping packets from the particular src
wouldn't work.

I'm probably missing something basic here...

OK, let me rephrase -- even if you can have packets for two different 
applications arriving on the same TCP port, actually doing so would be 
going against one of the basic design tenets of IP (the unique 
address/protocol/port identifier).

I'd strongly recommend against such a setup.  Apart from being totally 
incomprehensible to anyone else (or even to yourself 6 months after you 
set it up), it'll be impossible to replicate properly, and extremely 
fragile -- you don't write applications that break when a client 
upgrade changes the value of one bit in a packet somewhere.

All in all, a horribly dirty hack which I personally wouldn't touch with 
a 20-metre barge pole.

[ilugd] Web server system capacity analysis and reporting

2008-07-25 Thread Piyush Kumar 
Hello All,

Is there a good Open source tool for web server system capacity
analysis and reporting.

I am currently using Apache JMeter as a performance load test tool.

Also please suggest good ways/approach to do capacity analysis of servers.
