My dnsmasq sometimes forgets the hostname of one of my boxes. I wonder how to track that without tweaking the source?
My reconnect script reports: ... ssh: connect to host optiplex port 22: Connection refused rc '255'. root@optiplex @ Fr 30. Mai 11:27:43 CEST 2014 ssh: connect to host optiplex port 22: Connection refused rc '255'. root@optiplex @ Fr 30. Mai 11:29:01 CEST 2014 ssh: Could not resolve hostname optiplex: Name or service not known rc '255'. root@optiplex @ Fr 30. Mai 11:30:20 CEST 2014 ssh: Could not resolve hostname optiplex: Name or service not known rc '255'. root@optiplex @ Fr 30. Mai 11:31:40 CEST 2014 ... My setup is like this: * A FritzBox 7360, which acts as DHCP and DNS server. * My Workststation running openSUSE 11.4, with dnsmasq-2.70, it acts as DNS for localhost and as DHCP proxy to provide TFTP to other hosts. Compile time options: IPv6 GNU-getopt no-DBus i18n IDN DHCP DHCPv6 no-Lua TFTP no-conntrack ipset auth no-DNSSEC * A Testhost named optiplex. It is reachable with IPv4 and IPv6. When the failure above happens, my workstation fails to resolve optiplex. Restarting dnsmasq helps. olaf@probook:~ $ host optiplex olaf@probook:~ $ host optiplex fritz.box Using domain server: Name: fritz.box Address: fd00::a96:d7ff:feb1:1e3d#53 Aliases: optiplex.fritz.box has address 192.168.2.102 optiplex.fritz.box has IPv6 address 2001:a60:1011:601:baac:6fff:fea3:7d0a optiplex.fritz.box has IPv6 address 2001:a60:1011:601:30e6:8090:5088:397 optiplex.fritz.box has IPv6 address fd00::30e6:8090:5088:397 optiplex.fritz.box has IPv6 address fd00::baac:6fff:fea3:7d0a olaf@probook:~ $ host optiplex 192.168.2.1 Using domain server: Name: 192.168.2.1 Address: 192.168.2.1#53 Aliases: optiplex.fritz.box has address 192.168.2.102 optiplex.fritz.box has IPv6 address 2001:a60:1011:601:baac:6fff:fea3:7d0a optiplex.fritz.box has IPv6 address 2001:a60:1011:601:30e6:8090:5088:397 optiplex.fritz.box has IPv6 address fd00::30e6:8090:5088:397 optiplex.fritz.box has IPv6 address fd00::baac:6fff:fea3:7d0a olaf@probook:~ $ olaf@probook:~ $ sudo su - root's password: root@probook:~ # rcdnsmasq restart Shutting name service masq caching server done Starting name service masq caching server done root@probook:~ # logout olaf@probook:~ $ host optiplex optiplex.fritz.box has address 192.168.2.102 optiplex.fritz.box has IPv6 address 2001:a60:1011:601:baac:6fff:fea3:7d0a optiplex.fritz.box has IPv6 address 2001:a60:1011:601:30e6:8090:5088:397 optiplex.fritz.box has IPv6 address fd00::30e6:8090:5088:397 optiplex.fritz.box has IPv6 address fd00::baac:6fff:fea3:7d0a olaf@probook:~ $ host optiplex fritz.box Using domain server: Name: fritz.box Address: fd00::a96:d7ff:feb1:1e3d#53 Aliases: optiplex.fritz.box has address 192.168.2.102 optiplex.fritz.box has IPv6 address 2001:a60:1011:601:baac:6fff:fea3:7d0a optiplex.fritz.box has IPv6 address 2001:a60:1011:601:30e6:8090:5088:397 optiplex.fritz.box has IPv6 address fd00::30e6:8090:5088:397 optiplex.fritz.box has IPv6 address fd00::baac:6fff:fea3:7d0a olaf@probook:~ $ How can I find out why optiplex fails to resolve?
