I am running BackupPC 3.3.0 on an Ubunut 12.04.3 system. My hosts (which are
all Windows PCs accessed via SMB) are set to dhcp=0, which has worked well over
several years/versions of BackupPC. According to the docs on "How BackupPC
Finds Hosts", these sequence is:
- first gethostbyname()
- then nmblookup if the DNS lookup fails.
However I am on Time Warner/Road Runner which apparently does DNS hijacking in
my area. So EVERY DNS lookup is successful. Any lookup of a non-existent host
returns the TWC search page address.

> nslookup asdfkkkeiioqllllsajjppp
Server: 24.25.5.61
Address: 24.25.5.61#53
Non-authoritative answer:
Name: asdfkkkeiioqllllsajjppp
Address: 66.152.109.110
Name: asdfkkkeiioqllllsajjppp
Address: 69.16.143.110
> perl
use Socket qw(inet_ntoa);
my $host = 'ajslfjdkajwjkejkfsdfdjkasfjdklaskdfasjdas';
my ($name,$aliases,$addrtype,$length,@addrs) = gethostbyname($host);
printf("Host's address is %s\n",inet_ntoa($addrs[0]));
Host's address is 66.152.109.110
------------------------------------------------------------------------
As a result, trying to backup "mediaserver" will result in BackupPC earnestly
trying (and failing) to backup 66.152.109.110
I would prefer that BackupPC simply skip the gethostbyname() part and go
straight to nmblookup:
> nmblookup mediaserver
querying mediaserver on 10.4.9.255
10.4.9.3 mediaserver<00>
Is there a way to do this - to disable the DNS lookup of hosts, at least for
SMB hosts?
Thanks to anyone who can help.
