It should be *very* obvious to you that there is something wrong with the data (netmask?) you entered or with the way you did it. Continued telling that you "configured ip on eth2" is not better than telling what you had for breakfast today. *Provide complete information* Have you even considered using Google? http://www.google.de/search?hl=de&num=30&q=%22netmask% 3A+Host+name+lookup+failure%22&meta=&aq=f&oq= And, is that *really* CentOS 2.1?
