I run a small home network with dnsmasq running on one of the machines to provide DNS and DHCP services. It all works fine but I've just noticed that when I connect a laptop running xubuntu 11.10 to the system it doesn't register its name with the dsnsmasq server.
Other machines seem to provide names without a problem (also running xubuntu 11.10 or 11.04). The laptop is working OK in every other respect, it can see the internet and DNS works fine. The server is running dnsmasq version 2.52 and runs ubuntu 10.04 LTS. It's pretty much a default setup, there are some static addresses set up in /etc/hosts:- 192.168.1.1 vigor 2820n 192.168.1.2 dps dps.zbmc.eu 192.168.1.3 hp7310 HPEDDBB7 HP000D9D068F7D 192.168.1.4 chris wiki boat info zbmc.eu 192.168.1.5 maxinexp 192.168.13.254 2wire BT2700HGV gateway.2wire.net ... and some simple additions to /etc/dnsmasq.conf:- # # # Custom additions # address=/www.google-analytics.com/127.0.0.1 address=/ssl.google-analytics.com/127.0.0.1 address=/www.addthis.com/127.0.0.1 dhcp-host=00:90:a9:70:06:ff,backup dhcp-host=40:61:86:98:f2:41,chris local=/zbmc.eu/ If I do "arp-scan -l" from my desktop machine (chris) I see:- 192.168.1.1 00:50:7f:8b:35:40 DrayTek Corp. 192.168.1.2 00:01:6c:6c:c7:9b FOXCONN 192.168.1.6 00:04:4b:07:13:30 NVIDIA 192.168.1.83 00:50:8d:93:fd:09 ABIT COMPUTER CORPORATION 192.168.1.88 00:90:a9:70:06:ff WESTERN DIGITAL 192.168.1.99 00:23:8b:de:b6:d9 Quanta Computer Inc. 192.168.1.122 78:ac:c0:63:90:d4 Hewlett Packard 192.168.1.84 70:f1:a1:2d:da:86 Liteon Technology Corporation ... and then:- root@chris:~# host 192.168.1.83 83.1.168.192.in-addr.arpa domain name pointer test.zbmc.eu. root@chris:~# host 192.168.1.99 Host 99.1.168.192.in-addr.arpa. not found: 3(NXDOMAIN) root@chris:~# host 192.168.1.84 84.1.168.192.in-addr.arpa domain name pointer laptop.zbmc.eu. root@chris:~# So why doesn't 192.168.1.99 have a name? Both test.zbmc.eu and laptop.zbmc.eu are running versions of xubuntu and they work perfectly OK. The only *very* slight difference with 192.168.1.99 is that its name is acer-aspire, would that '-' have any effect? -- Chris Green _______________________________________________ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
