[newbie] Using Mandrake 10.1 as DHCP Server
I currently have a Lynksys Router setup to handle the DHCP on a 192.168.4.0/255.255.255.0 network. The computers are setup with 192.168.4.1 (the address of the router) as the gateway. I tried setting up DHCP on Mandrake and disabled on the router. The Mandrake box could access the internet, but the remaining Windows boxes could not. The gateway on the Windows boxes was set to 192.168.4.111 which is the static IP of the Mandrake box. I tries setting up the Mandrake box as a proxy (I've been using drakwizard to set these up) using squid, but the the Windows box still could not access the internet. I did change the proxy settings on the Windows box to use ip 192.168.4.111 and the port suggested by drakwizard. What is it that I need to do? My goal is to have everything routed through the Mandrake box under one firewall. Eventually I would like to expose the server to the outside world (using dynamic dhcp) so that I can do some remote access when I travel (ftp mainly). Any help would be greatly appreciated. -- Christopher Taylor - Registered Linux User #383327 If this message is sent to a mailing list please 'Reply to List' or re-write the To field.

The gateway is the box that is physically connected to the internet. That is still your Linksys, so you must set 192.168.4.1 as the gateway address regardless which box is the DHCP server. (I assume the Windows boxes are also on the 192.168.4 subnet) If you are using Squid proxy, then the Windows clients will not need the Linksys as a gateway for browsing, but the Windows clients must be configured to use a proxy on 192.168.4.111 port 3128 If you still have problems check you do not have a firewall on the Linux box blocking access to the proxy. BTW: You could keep the Linksys but set it up to do port forwarding to the Linux box for your remote access. Your Linksys manual will describe port forwarding. You can still use dynamic DNS (which is what I assume you mean by dynamic dhcp) by using ddclient to update dynamic DNS servers with the external IP address of the Linksys. derek -- www.jennings.homelinux.net http://twiki.mdklinuxfaq.org Want to buy your Pack or Services from MandrakeSoft?

Go to http://www.mandrakestore.com Join the Club : http://www.mandrakeclub.com I'll give the 192.168.4.1 gateway a try. I had the Windows box set to use the proxy at the right IP and port. I checked the firewall settings under the control panel and it showed to let everything through. The real trick to exposing isn't the Linksys Router, but the Westell 2200 DSL modem. This does not seem to want to let anything through. I will try googling and see what I can come up with. -- Christopher Taylor - Registered Linux User #383327 If this message is sent to a mailing list please 'Reply to List' or re-write the To field.

UNless you are planning on setting up a proxy server on the Linux box, set the gateway setting in the dhcpd config to the address of the Linksys box. (192.168.0.1) You will also want to set the name server address (DNS). You may want to consider running a name server on the Linux box, and having the Windows machines use that. This offers a couple of advantages. You can also have it manage the IP addresses for the local netowork. It can also save haing to go to the Internet to look up the names of common sites. This can make getting to the sites faster. You only have to go to the Internet for the first machine that visits the site. A second machine on the locak network visiting the site gets the address that is stored on the Linux machine. If you are interested, I will look in my notes for the name of the one I used to use. It had nice features like reading the dhcp lease file, and adding the machines from there to its database dynamicly.

I will have to check to see if they are blocking, but I don't think so as you will see below. The Westell modem is also a router with one port. I tried having the modem handling the PPoE and the router set to a static IP in the range of the subnet specified by the modem.The router modem was set with port forwarding to the router and the router was set with port forwarding to the linux box (also a static ip on the subnet). At this point I could ping the assigned dynamic IP (I use http://www.dnsstuff.com). The Linksys router showed nothing in its incoming logs. The Windows boxes could access internet sites by IP only. The name lookup was no longer working. The linux box was fine. This was when the Linksys rep said that the modem had to be in bridge mode. Once put into bridge mode, I could no longer ping the assigned IP, but the Windows boxes could access the named sites. The router is now handling the PPoE and DHCP. My goal is to have the linux box control the other boxes. I think that you are right in that I need to set up DNS. There is a setup for that in drakwizard, but I do not know what to do with it. I believe that it asked me to change the hostname. I explore more when I get home.

I believe that it asked me to change the hostname. I explore more when I get home. Thanks for the help everyone. I would take things in small steps. Get each step working beofre moving on the the next step. If you are going to use the Linux box as a dhcp server, get that set up first. You will have to specify the address of the Linksys box as the gateway, and you also have to specify the name server as part of the dhcp setup. If I remember correctly, the Linksys box acts as a caching name server. If so, you can use that as the name server for the initial setup. If not, take a look at /etc/resolv.conf - you can use the name servers listed there at first. option routers192.168.0.1; option domain-name-servers192.168.0.1; If you are running Samba on the Linux box, and it provides a Wins server, you may want to add: option netbios-name-servers IP of Linux box; You may want to look into running dnsmasq on the Linux box, and having the Windows boxes use the Linux box as their name server. http://www.routerlinux.com/docs/manual/man8/dnsmasq.8.html I like it because it will read the /etc/hosts file on the Linux box, and add that to its database, as well as watching /var/lib/dhcp/dhcp.leases and adding hosts assigned IP addresses there. It works great for small networks. I have not tried it on a large network. It also works good with dialup connections. Once you have this working, set up the services you want to run on the Linux box, and make sure you can access them from other machines on the local network. That way, you will know if you have any firewall issues, or configuration problems. One of the first services I would configure is ssh. Configure the Linksys box to forward incomming ssh connections to the Linux box. Try connecting from a remote host. Is it working? If not, check the logs on the Linux box to see if the connection made it that far. If not, double check the Linksys box to make sure the changes are there. I have noticed that some routers will show the changes when using Firefox, but if you refresh the page, they didn't take. As far as the mode of the modem and router, I would let the modem handle PPPoE, and run the Linksys box set for a dynamic IP WAN connection. But this is more my prefference then anything else. You should be able to set it up, and make it work ether way. Mikkel -- Do not meddle in the affairs of dragons, for you are crunchy and taste good with Ketchup!
