I have a cron job running every 20 minutes monitoring a temperature sensor for minor changes in trend up/down. This has been running for a few months. Today at 1521 I got a warning that the trend dad changed to slightly upward. The next one failed on a DNS issue. The puzzle: wget -nd http://office20.local.net:4444/--slope--/1.2.3.4/0 --2016-08-12 20:38:24-- http://office20.local.net:4444/--slope--/1.2.3.4/0 Resolving office20.local.net (office20.local.net)... failed: Name or service not known. wget: unable to resolve host address ‘office20.local.net’ So clearly "office20.local.net" does not resolve. Except:
host office20.local.net office20.local.net has address 192.168.3.20
ping office20.local.net PING office20.local.net (192.168.3.20) 56(84) bytes of data. 64 bytes from office20.local.net (192.168.3.20): icmp_seq=1 ttl=64 time=0.029 ms 64 bytes from office20.local.net (192.168.3.20): icmp_seq=2 ttl=64 time=0.040 ms

No changes were applied to this system for at least a month, likely longer. Why can't wget resolve the address when others have no problem? -- Per Jessen, Zürich (21.2°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
