Hi

I want to try a php based software. It is encrypted and I am scared, it might send out important information to the software vendor site(s)

Since the code is encrypted so i cannot check the code to verify this. I wanted to install some tool or use any command which can show me if the software sends / calls any third party site anywhere in the software.

please advise me on this.

thank you

You could load it in a Virtual machine or isolated physical machine with Netfilter blocking traffic plus 0) "-j LOG" rules or 1) a packet sniffer like tcpdump or 2) the network disabled (hoping it will complain) or 4) preloading some proxy like Dante or route all traffic through a proxy. Since this could be a commercial product (which one, details?) in-depth debugging might be a valid option but against the license.

Just run Wireshark if you have a graphical interface on the box and see what it does.

As I said in my reply there will be no hinting at debugging.

Thank you guys for your replies. I do not want to debug / steal any code from the software. The software company is not scared of that either. I have written my own software which is far better than this one. The only thing is that one of our client wants it to be installed on his VPS (whm/cpanel) to track his PPC sales. The problem is that most of the people think this software steals keywords lists and CTR information from customers and load it to the company site for their use. So I am not after stealing any code from the software but to avoid any possible theft of important information from my client.

Anyway, I have decided to install it on a internet-less machine and check all features, if it does communicate with company site, it will break on those part of the software.

thank you!
