Looks like ifconfig makes use of them too. Does this work for configuring a single ethernet interface to have more than one IP address? Has anybody tried this to make a single machine appear to be two separate Internet nodes? -- Chris Roehrig (croehrig@cs.ubc.ca) Dept. of Computer Science, University of British Columbia, Canada
