The whole naming system is based on one system name with possibly multiple addresses. You can have multiple A-records in the DNS data base. You can have multiple lines giving different addresses to the same name in /etc/hosts. You can even enter the /etc/hosts entries as address1 official_name alias1 address2 official_name alias2 so that when starting up the system you can use the different aliases to specify the particular interfaces, but still keep the same name for each. For that matter you can use the internet address in the 'ifconfig' command to distinguish, with the advantage that if you have an /etc/resolv.conf there is no longer the extended delay while 'ifconfig' times out on all nameserver entries before reverting to read the /etc/hosts file. -- =*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*=*= Neil W.
