Hi all! I know a little of linux, bash scripting and networking. I have a debian stable machine, with apache + php+mysql that provide a webinterface written by me. That machine would have no default routing and many gateway. On the lan side, people can only connect to the server via the webinterface and allow a certain computer to connect creating on the fly the routing on the selected gateway.
I think that doing this by MAC address would do. For now, I've made a simple bash script that I execute from PHP and it would return me the mac address given the ip, otherwise after a reasonable timeout return NONE which would tell me that the user is not online. I'm looking at iproute2 and of course netfilter, I'm not really sure if I should use bash scripting or not, and in case, when I execute a script from php the priviligies are as Apache, which is limited, and I might need root priviligies, what should I do ? Change apache priviligies, sudo the script, i'm really not sure. thanks all for attention and i hope i'm on topic. Lawrence
