How I can controll the remote acces to my sco box?

[fonso]

I have installed te tcp-wrapper and it works well.
But I need more access controll. With the tcp-wrapper anyone can change your ip and acces to the server suppling the other machine. How can I control the access, using the MAC address or the arp protocol ?.
If I know the mac address of the lan card, there is no possible to do this. But , i can't controll this whith the tcp-wrapper.

Thank you.
sorry about my english.

I'm not aware of any software that can be used to deny access via MAC address. It's not that easy to change your IP address. Normally when you do it you're only limited to changing it to certain subnets, otherwise it won't route properly.
Really your security should be done by the applications that run on the SCO box. If it's logging in that you're concerned with then you should make sure you're using complex passwords. If it's a network service you are worried about (say an Oracle database) then the authentication needs to be done at that level (within the Oracle database say).

Thank you for your time Wonboodoo.
The problem I it's when one computer connected into my local network can change your IP and access to my SCO Box.
For example , in my SCO I have access permited to the 192.168.1.5 , .6, .7, and .8 IP's.

When other PC in my local network, one like 192.168.1.30 would access to my SCO box, simply can change your IP for the .5 for example , and can access to my SCO box.
If I have the possibilitie to deny the access controlling the MAC adress, the only possibilitie can be changing the network card from one pc to another.

Thank you from Spain.
