<div>Update on this issue, but still not fully resolved....<br>
<br>
<div>I received the following advice from Simon:</div>
<div><br>
</div>
"> To set the mbdevices tag, you need to use dhcp-match to look for MB in<br>
> the hostname option (which has number 12).<br>
>> dhcp-match=set:mbdevices,12,MB<br>
>> Almost works, but it will match MB anywhere in the host name.<br>

<br>
<br>
I have currently:<br>
<br>
dhcp-range=192.168.0.2,192.168.0.10,255.255.255.0,12h<br>
dhcp-range=tag:mbdevices,192.168.0.50,192.168.0.60,255.255.255.0,12h<br>
dhcp-range=tag:!known,192.168.0.11,192.168.0.20,255.255.255.0,12h<br>
<br>
and have tried each of the lines:<br>
<br>
dhcp-match=set:mbdevices,option:hostname,MB<br>
dhcp-match=set:mbdevices,option:hostname,4d:42<br>
dhcp-match=set:mbdevices,12,MB<br>
dhcp-match=set:mbdevices,12,4d:42<br>
dhcp-name-match=set:mbdevices,MB*<br>
<br>
and the devices with hostnames starting with MB are all being allocated to the !known range.<br>
The log doesn't appear to show any errors, just that the devices were allocated an IP in the wrong range.<br>
<br>
Log extract:<br>

><br>
<br>
dhcp-match=set:mbdevices,12,MB seems to work in that it applies the tag some of the devices but not others, but it puts them in the in the !known range<br>
<br>
dhcp-match=set:mbdevices,12,4d:42 does not appear to work<br>
<br>
dhcp-name-match=set:mbdevices,MB* appears to tag more consistently but still the devices do not get allocated to the mbdevices range.<br>
<br>
Any help would be really appreciated.<br>
Thanks<br>

<div dir="ltr">Hi,</div>
<div dir="ltr">I am trying to allocate all hosts that join my network with a hostname beginning 'MB' to a specific DHCP range.</div>
