Posted: Mon Aug 24, 2009 5:57 pm Post subject: Static IP with dnsmasq |
|
|
I'm running dnsmasq on my router/server now but I want to give some clients a specific IP and others an ip from a limited range.
So I configured my dnsmasq as instructed by the comments:
Code: | RoSe v1per # confcat /etc/dnsmasq.conf
domain-needed
interface=eth0
dhcp-range=192.168.0.200,192.168.0.250,24h
dhcp-host=00:23:54:7C:C6:0B,elise,192.169.0.10,24h
dhcp-host=00:13:D4:F0:B3:C2,sarah,192.169.0.20,24h
dhcp-option=option:ntp-server,0.0.0.0
dhcp-option=19,0 # option ip-forwarding off
dhcp-option=44,0.0.0.0 # set netbios-over-TCP/IP nameserver(s) aka WINS server(s)
dhcp-option=45,0.0.0.0 # netbios datagram distribution server
dhcp-option=46,8 # netbios node type
dhcp-option=47 # empty netbios scope.
dhcp-option=vendor:MSFT,2,1i

My DHCP and DNS work just fine, except I don't get the IP I wanted to (elise) on my windows clients:
Code: | Ethernet adapter Local Area Connection:

What did I do wrong? |

well, your range is from 200 to 250 but you try to assign 10. What happens if you change either your range or the assigned ip to something like 220? _________________ Study finds stunning lack of racial, gender, and economic diversity among middle-class white males

I noticed too and changed it so the static ip's are in the range, but to no avail. Also according to the documentation it should work outside the range:
Quote: | # Supply parameters for specified hosts using DHCP. There are lots
# of valid alternatives, so we will give examples of each. Note that
# IP addresses DO NOT have to be in the range given above, they just
# need to be on the same network. The order of the parameters in these
# do not matter, it's permissble to give name,adddress and MAC in any order |

since I don't have windows .. only a linux box which gets the right ip (the network with windows boxes is served by isc dhcp)... are you sure that the windows box gets its ip from your dnsmasq running box? What does your log say about this? _________________ Study finds stunning lack of racial, gender, and economic diversity among middle-class white males

I have a very similar config, and it works fine. (only difference, is that I specify the mask in the dhcp range, but that should not be required)
Maybe dnsmasq thinks the reserved address is already in use. Check the /var/lib/misc/dnsmasq.leases file, and if there is an entry for your reserved address, delete it. (you might need to restart dnsmasq after) |

Doesn't seem to be in use (well it is now, but when I disconnect the pc, it disappears) |
