a couple of days before, I made an inquiry in the chat room about blocking all .swf file extension using win hosts, granted that I cant do it in the said method, I blocked most timewaster websites I know:
Code: Select all
127.0.0.1 facebook.com
127.0.0.1 youtube.com
however, the unit can still surf those websites, what did i do wrong?

I don't really want to debug your networking issue, but I'd just like to say that if you're using firefox or chrome (and probably opera and others), that you can get an extension called flashblock that does exactly what you want.

only problem is the user is using IE 8,
edit: ah yes flashblock is available in IE too, thanks for the input... BUT still if the user is kind-off technical genius he/she could easily thwart my security settings, right?

ohh ok, I misunderstood your intentions. so you're trying to block flash for users on a work network? and we're assuming the users are hostile?
I don't have much experience with this kind of network administration, so take everything I say with a grain of salt, but you might try blocking flash by rerouting all traffic to a transparent squid proxy on the gateway machine, then with a perl script that blocks certain file extensions and sites. here's where I got that idea, so you can use this for an example:
http://www.ex-parrot.com/pete/upside-down-ternet.html
there might be an easier/better way to do all this, idunno. of course this can be bypassed if they use their own proxy.

nice trick, I could use that site for my wifi at home, is it also applicable to pc connected to lan? *since it uses the pc's mac address to block that unit*
with that file location I'm assuming that dhcpd.conf is saved in
right?
Code: Select all
subnet *.*.*.* netmask 255.255.255.0 {
range *.*.*.* *.*.*.*;
option routers *.*.*.*;
option subnet-mask 255.255.255.0;
option domain-name "XXXXX";
option domain-name-servers *.*.*.*;
deny unknown-clients;
host trusted1 {
hardware ethernet *:*:*:*:*:*;
fixed-address *.*.*.*;
}
}
this code refers to all units supposed to be blocked off the net right?
and that the succeeding code refers to all allowed units (correct if I'm wrong)
and umm IPTABLES... the strings of command is doable via cmd?
the redirection script... where should I put it?
ty for the help
