You can create your own task to do this. See for example one I just created: https://hudson.apache.org/hudson/job/Ubuntu1/2/console which unfortunately shows that Yahoo! DNS is (incorrectly) resolving the .invalid TLD Maybe someone should tell them... Ubuntu2 seems to be OK however: https://hudson.apache.org/hudson/job/Ubuntu2/2/console >>>> resolves to 98.137.132.14 (nx1.ycpi.vip.sp2.yahoo.net) on ubuntu1?
