[opensuse] Can't add 2nd DHCP range
I'm trying to add a second DHCP range for a a subnet on a VLAN. However, when I try to save the configuration, I get an error "Error occurred while restarting the DHCP daemon". I have rechecked the configuration for that 2nd range and I don't see any problems. How can I find out what the problem is? Dmsg doesn't show anything and there doesn't appear to be anything relevant in /var/log. I'm running openSUSE 13.1. tnx jk -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I tried recreating the configuration from scratch and while I now have both ranges configured, the server hands out the wrong address range for the VLAN. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The LAN & VLAN have different subnets, so the DHCP server hands out addresses accordingly. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Isn't this a contradiction? First you say that "the server hands out the wrong address range for the VLAN", and then "the DHCP server hands out addresses accordingly"? So, where's the problem now? confused, Werner -- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

So, where's the problem now? The "wrong addresses" was my fault. Most of the devices on my network

This means the server will always hand out that address, no matter which subnet it's in. I had to remove one of my computers MAC address from the DHCP server for testing. What I was setting up was a guest WiFi network. My access point supports VLANs and multiple SSIDs. I have configured the guest SSID to use a VLAN and then configured my firewall to put that VLAN in the DMZ. The DHCP server then hands out the appropriate addresses to guest computers. My firewall is set up so that only DHCP requests and SSH are passed from the DMZ to my home network. It's also set up so that only SSH or SSL is passed from the Internet to my home network. My next project is to see if I can get one of my IPv6 subnets working on the guest VLAN. I have a /56 IPv6 subnet, which is in fact 256 /64 subnets. I'm only using one on my home network. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Usually I find dhcpd error messages in /var/log/messages.
Not only that, but the first range 192... appears under the wrong subnet. Actually, I see the marked error in the spew that dhcpd kicks out when you restart it, usually its the first thing it says, and the error is marked with a ^ symbol. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I just decided to start from scratch and that cleared that problem. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I figured that one was the duplicate - cut&paste?
