New Revision: 62178
URL: http://svn.opensuse.org/viewcvs/yast?rev=62178&view=rev
Log:
Enhanced the test_* tools to do the most meaningful test first
so that ICMP echo (ping) is no longer required in any case
(see Novell/Suse Bugzilla bnc#616706).
This is an enhancement for after openSUSE 11.3
Increased VERSION to 2.19.14
