Re: [Server-devel] DNS/dhcp question
Jerry, I am not trying to be vague about anything. I would love to give you a sense of what is happening. I want to apologize ahead for not being clear. Not all of this makes perfect sense to me. Current situation: My XS box has 2 NICS Eth0 connects to the school internet and has a static IP address (10.125.105.153; subnet 255.255.248.0) Eth1 connects to a VLAN set up for the XOs. The Access Points for the VLAN point toward the XS box as the DHCP server (so I'm told). I was given that IP address by my tech guy. Here are the parameters: -IP range is 10.125.140.0 -Give the SchoolServer an IP address of 10.125.140.31, -set up DHCP for a range of 10.125.140.100 - 254. -Subnet mask should be 255.255.248.0 Ongoing questions: 1. I have been working under the assumption that eth1 should have the Schoolserver address above (10.124.140.31). Is that correct? 2. What do I need to do (if anything) to configure the DHCP functions of the XS? 3. Is there anything else you need to help with this. Thanks.

Subnet mask should be 255.255.248.0 Don't think you want to mess with the XS's eth1 setup, that is pre-configured to use a different network, if you have dhcpd running on the schoolserver (check with service dhcpd status) the clients should be able to ping the schoolserver without the internet. Please tell me how to set this up. Before I comment, what is the output of ip route ls and arp -n while connected to the internet? Thanks. Once again, I am trying to deploy 150 machines and this is important. Those 150 machines should be able to ping the schoolserver, at least by ip address. Do the client machines even get an ip address to use? If so what is it? Can any of the client machines ping the schoolserver @ 172.18.0.1 or 172.18.96.1?

[Server-devel] DNS/dhcp question
Hello. I have the XS server up and running on a Dell. Per specs, I believe, I have two NICs, which I can see as eth0 and eth1. Eth0 is connected to the internet. Eth1 is connected to the AP for the XOs. Or, more accurate, the AP for the XOs points to eth1. (I hope this is correct). I have two problems: 1) When I connected to the AP from the XOs, no IP address is generated. 2) We are going to use a hosted XS off site, and I want to configure my box (which is the dhcp server) to point to it.
