Others have already pointed out that root users on the workstations can do pretty much anything they want. However, you could use 'arp -s <ip addr> <ethernet_addr>' so that your FreeBSD machine will still speak to the correct machine for the given IP address. Just do an 'arp -a' when all of the IPs are set correctly and copy down the corresponding ethernet addresses. Of course, unless other machines on the network are similarly configured, a workstation user could still change his IP and mess up other systems on the LAN. --Ludwig Pummer ( ludwigp@bigfoot.com ) ICQ UIN: 692441 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
