Hi List, I have been needing a dhcp proxy in our environment spicifically to proxy pxe requests to a tftp server. I am using RHEL6.3 and have the following versions installed:
dnsmasq-2.48-6.el6.x86_64 I have also tried the latest to see if there were bugs related to this that got fixed. The DHCP server is another Linux server and uses next-server to pass requests to the proxy DHCP server (dnsmasq server) and for the most part works like a charm. However, I am not able to ignore spicific hosts based on mac address. Here is my conf file: port=0 listen-address=192.168.0.5 log-dhcp tftp-root=/var/lib/tftpboot dhcp-boot=pxelinux.0 dhcp-option=vendor:PXEClient,6,2b dhcp-no-override pxe-prompt="Press F8 for boot menu", 0 pxe-service=X86PC, "Boot from network", pxelinux pxe-service=X86PC, "Boot from local hard disk", 0 dhcp-host=1c:c1:de:20:3b:0a,ignore dhcp-range=192.168.0.5,proxy As you can see, I have a host listed with mac address and ignore listed. But, when this host network boots, it is still routed to the pxelinux menus. I have tried the follownig - Not all at once, however: dhcp-host=1c:c1:de:20:3b:0a,net:nopxe and dhcp-ignore=tobeignored dhcp-mac=tobeignored,1c:c1:de:20:3b:0a Neither of these work. Here are some bits from my log: Jan 10 10:15:46 DL380G7G44U10 dnsmasq-dhcp[24739]: 3743431434 Available DHCP subnet: 192.168.0.5/255.255.255.0 Jan 10 10:15:46 DL380G7G44U10 dnsmasq-dhcp[24739]: 3743431434 Vendor class: PXEClient:Arch:00000:UNDI:002001 Jan 10 10:15:46 DL380G7G44U10 dnsmasq-dhcp[24739]: 3743431434 PXE(eth1) 1c:c1:de:20:3b:0a proxy Jan 10 10:15:46 DL380G7G44U10 dnsmasq-dhcp[24739]: 3743431434 tags: known, eth1 Jan 10 10:15:46 DL380G7G44U10 dnsmasq-dhcp[24739]: 3743431434 bootfile name: pxelinux.0 Jan 10 10:15:46 DL380G7G44U10 dnsmasq-dhcp[24739]: 3743431434 sent size: 1 option: 53:message-type 05 Jan 10 10:15:46 DL380G7G44U10 dnsmasq-dhcp[24739]: 3743431434 sent size: 4 option: 54:server-identifier 192.168.0.5 Jan 10 10:15:46 DL380G7G44U10 dnsmasq-dhcp[24739]: 3743431434 sent size: 9 option: 60:vendor-class 50:58:45:43:6c:69:65:6e:74 Jan 10 10:15:46 DL380G7G44U10 dnsmasq-dhcp[24739]: 3743431434 sent size: 17 option: 97:client-machine-id 00:35:38:33:39:31:34:55:53:45:30:35:30...

So, I tried this: dhcp-host=1c:c1:de:20:3b:0a,id:*,ignore and this did not work either. Anyone have any ideas how I can get this to work? Thanks so much!
