Hi everyone,
does anyone know who to setup dhcp on a linux server???

Sorry,
I forgot to mention, setup dhcp on a linux server on a windows network running dhcp.

the 1st question made sense, then the second part you added threw me off....do you mean the Linux server will give IPs to windows machines? Well 1st off, that doesnt matter. But to set up DHCP you need to edit the dpchd.conf file to look something like this:

Code:

subnet 10.0.1.1 netmask 255.255.255.0 {
# --- default gateway
        option routers                  10.0.1.1;   #the address of the interface giing out IPs
        option subnet-mask              255.255.255.0;
        #option nis-domain              "domain.org";
        #option domain-name             "domain.org";
        option domain-name-servers      192.168.1.1; #DNS SERVERS
        option time-offset              -18000; # Eastern Standard Time
        range dynamic-bootp 10.0.1.100 10.0.1.254;
        default-lease-time 21600;
        max-lease-time 43200;
}

also you may wanna look at a HOWTO, those explain more. Try googling for dhcpd or dhcpd-howto or dhcp-howto until you get what you are looking for.

To run the server you just typed: dhcpd
and if all is good, it runs. You may get an error if you dont have a file called dhcp.leases, you can create it like so:

# touch /etc/dhcp.leases

you dont have to edit it, it just has to be there.

actually, i have a linux server but i have a windows network that is using dhcp. Is there anyway to have the linux server lease an IP from the windows 2000 dhcp server?? thanx for the reply though.

thats simple, what you want is a dhcp client. Robert0380 told you how to setup a dhcp server.

just run network configuration tool and set your network card to use dhcp to get the ip and off you go

masenko703 · 05-24-2003, 07:45 PM

how do you do that?? what network configuration tool??

Try running 'netconfig' in a terminal as root.

acid_kewpie · 05-25-2003, 04:45 AM

in /etc/sysconfig/network-scripts/ifcfg-eth0 just set the line "BOOTPROTO=DHCP" and that's all yuo need to do. that is what netconfig will do

Robert0380 · 05-25-2003, 06:56 AM

try running the following command:

dhcpcd eth0

if that works, then the client is now running. If there is a server giving out IP addresses then the Linux box should get an address.

yo ---

i'm trying to follow this, and have been starting with a direct cross-cable connection between my (dumpy) old Win ME laptop and my freshly built SuSe box.

i've edited the dhcp.conf file to bare bones, trying to get a response, but when i type in "dhcpd" in the command line of the shell-konsole, all i get back is "bash: dhcpd: command not found". i've tried running this from the root directory, and the etc directory, and no joy yet.

what the @&*!?

i can't begin to get anywhere until it listens to me...granted, i know i'm an idiot, but could this be a privileges thing? when i launch an admin function via the menus i get prompted for the network password. any help would be immensely appreciated.

What do you mean by a windows network, im assuming you dont have a windows server, which means you have a workgroup in windows. if you have a router, then that is what is assigning the leases. in which case, you type dhcpcd eth0. also what kind of network are you trying to set up? sharing an internet connection or transferring files or what?

yurlittlepony · 05-27-2003, 02:09 AM

well....my SuSe box is meant to be the server rather than the laptop, and since i'm using a cross-cable connected between the ME and the SuSe box, there is no router....which means i have to have SuSe run DHCP, correct?

as i mentioned, i get no responce from typing "dhcpd" in anywhich way or form, including followed by eth0.

for the moment i'm trying to get the two talking and sharing files with ME as client and SuSe as server. once i've dumped all of my criticals over to the SuSe server, it'll be time to purge the dreaded ME, and in a short weeks time i'll get a proper router and connect my broadband through the router to both systems w/SuSe acting as server.

my options: 1. wait for my router, and have the dhcp with the router or 2. figure out the answer to my question: why do i get a "command not found" error in the shell when i type any combination of "dhcpd". i'd rather solve the mystery and understand how this works.

arrruken · 05-27-2003, 02:29 AM

well are you sharing an internet connection right now because if your not then you dont need any dhcp, and i dont think dhcp would work anyway.i was talking about the router because of the originator of the post. i dont know how to direct connect pc's with linux. you should start up your own thread about direct connecting pc's.
