[tcpdump-workers] Running TCPDUMP over a web interface
Hi all, I am not sure if this is a right list to post the following question. I need to run TCPDUMP on a Linux bridge with multiple network interfaces. However, instead of using a shell, I need to run it over a web interface. Any guide or suggestion will be highly appreciated. Thanking you...

Re: [tcpdump-workers] Running TCPDUMP over a web interface
Hi Guy Harris, Thank you for the reply. My goal is to have a web interface and capture traffic and print in on the screen live but only when a certain command string is supplied. As stated, I need that web interface to be run over a Linux bridge box. For the time being, I only need this web tool to run the traffic dump over the br0 interface of that bridge with something like the following options: tcpdump -enn -i br0 vlan 999 Can you provide further information about how we can go about implementing this setup?

Dear All, Thank you for your valuable feedback. Is this setup were to be done or developed into a commercial product, how much will the cost be like?
