The terminals are used to produce some openoffice documents and in the majority to surf in the internet. The problem is that the students access the windows shares and another shares in the windows machines (we have passwords in the shares :-) ). How can i block the access to all services except "web access". It can be done with iptables? Our there is another simply way to do it?</FONT></DIV> <DIV><FONT face=Verdana size=2></FONT> </DIV> <DIV><FONT face=Verdana size=2>The server as two nic´s: one for the network for the terminals (eth0), and another receiving dynamic ip (eth1: this is the nic that gives accesso to the web) from a windows server.</FONT></DIV> <DIV><FONT face=Verdana size=2></FONT> </DIV> <DIV><FONT face=Verdana size=2></FONT> </DIV> <DIV><FONT face=Verdana size=2>Thanks in advanced.</FONT></DIV> <DIV><FONT face=Verdana size=2></FONT> </DIV></BODY></HTML>
