As Carl suggested, manually forcing a static IP address through DHCP is the best solution.
However, if that's not an option for whatever reason, the only other option would be to ensure that your dhcpd service is properly connected/integrated with bind [named] (assuming you are using these). Then ensure that your BackupPC server directly references the server hosting the bind instance referenced above. If you still have problems, you will likely need to restart the nscd (name server cache daemon) on your BackupPC server before querying for IP addresses. e.g.: Setup a cron job. A good way to tell if this will be beneficial is to hook up your laptop to the network and give it a minute or two to register with DHCP and DNS. Then run nmblookup -A HostnameOfLaptop to see if it finds it. If it doesn't, the above suggestion will likely help assuming bind is working properly. If it doesn't work, that's an indication you are having problems with dhcpd and named. ~Ryan -------------------------------------------------- From: "Carl Wilhelm Soderstrom" <chr...@real-time.com> Sent: Monday, February 07, 2011 11:49 AM To: <backuppc-users@lists.sourceforge.net> Subject: Re: [BackupPC-users] One more time > On 02/03 01:45 , David Williams wrote: >> Got a little free time so thought that I would try again to see how I >> can back up my laptop. >> It's set to DHCP and is connected to the same network as the BackupPC >> server. > > Is there any hope you can get a static IP address assignment for your > laptop, so that the BackupPC server doesn't have to 'hunt' for it? > > This is what we do everywhere, and it solves the problem perfectly. > > -- > Carl Soderstrom > Systems Administrator > Real-Time Enterprises > www.real-time.com > > ------------------------------------------------------------------------------ > The modern datacenter depends on network connectivity to access resources > and provide services.
