Hi,<br>
<br>
is there a way to "load balance" among dnsmasq servers?<br>
<br>
I have a network of a half dozen servers (with static IPs which I<br>
write down in /etc/hosts for dnsmasq to publish), plus about 50<br>
computers which get their IP and hostname from dnsmasq and use it to<br>
resolve dns, especifically, to know the IP of the servers and other<br>
PCs with very little "outside" queries... queries to outside dns are<br>
mostly done on behalf of the servers which need to connect to the<br>
outer world.<br>
<br>
What's more, for the 50 computers, I have compiled the MAC addresses<br>
and I'm giving them always the same IP/hostname (and no, I can't<br>
configure static IP in every computer).<br>
<br>
It seems that every now and then, one of the computers boot and can't<br>
get its own address via DHCP (I see nothing in the dnsmasq log so I<br>
think it may have missed a bunch of DHCP requests from the client at<br>
some point)... other thing that I also see happen is that cilents<br>
query dns and get no answer back...a few moments later, the same query<br>
gets an answer.<br>
<br>
I suspect that at some point, dnsmasq can't handle all the requests it<br>
gets (it is running on a busy server... but I also have seen something<br>
similar -dns queries not being answered- on a less busy server).<br>
<br>
I'd like to be able to put dnsmasq on 2 or 3 servers and that anyone<br>
of them be able to, at least, resolve dns... ideally, it'd be nice if<br>
it could also handle dhcp requests.<br></blockquote><div><br></div><div>In addition to what I already wrote, you may want to set the dhcp-option nameserver so that DHCP clients get a list of multiple dns servers to fall back on, instead of just the single dnsmasq instance that gave the DHCP lease.</div>

<br>
Any suggestions?<br>
<br>
TIA<br>
