 Posted: Wed Feb 15, 2006 7:08 pm Post subject: Setting up DCHP Server..Resolved |
 |
|
I follwed these instructions I found on a thread and everything seemed to be going good until the end. I did the following:
su -
yum install dhcp <ran successfully>
vi /etc/dhcpd.conf
ddns-update-style none;
authoritative;
subnet 192.168.1.0 netmask 255.255.255.0 {
# default gateway
# option routers 192.168.1.1;
option subnet-mask 255.255.255.0;
# option domain-name-servers 192.168.1.1;
range dynamic-bootp 192.168.1.2 192.168.1.99;
default-lease-time 10800;
max-lease-time 21600;
}
From the command prompt executed the following:
chmod 644 /etc/dhcpd.conf
And finally I typed -
service dhcpd start
Then I get the message:
starting dhcpd: [Failed]
Why would it fail? 
Please help I am on the verge of finishing this.

Hmmm, it looks like you don't have Gentoo installed yet.  |

yeah, besides this being a Gentoo forum, and not using Gentoo...
Problems with your config are that you don't have any default gateway defined (commented out) and no name servers defined (commented out). That probably wouldn't keep dhcp from starting, but then again it could.
Oh, and check your logs, it should kick out why it failed to start. (error in dhcpd.conf perhaps?)

Linux is linux: yes and no. We'll let you figure that part out for yourself. Ford, Chevy, Yugo and BMW are all cars, right? Pretty much interchangeable? It's all in the implementation.
Technically, this forum is here to help those who are using Gentoo. However, since I've only installed one time on a box I'm not using for anything, and since I'm answering some non-Gentoo questions, I suppose we can let it slide.
I don't think the default gateway clause is necessary, but I think the routers one is. Your subnet mask clause is redundant, get it out of there. Move your lease times down to 1 or 2 minutes for testing, it makes testing a whole lot easier.
Keep a terminal open with | Code: | | tail -f /var/log/messages |
while you do this stuff. It will tell you what's wrong in there. |

First off I apologize.. for the mistake. And I'd still appreciate any aasistance.
my /etc/dhcpd.conf has been changed to the following
ddns-update-style none;
authoritative;
subnet 192.168.1.0 netmask 255.255.255.0 {
option subnet-mask 255.255.255.0;
option domain-name-servers 192.168.1.1;
range dynamic-bootp 192.168.1.2 192.168.1.99;
default-lease-time 60;
max-lease-time 60;
}
I ran the command :
tail -f /var/log/messages
I get this long message:

For the record, that disclaimer prints every time dhcpd pukes.
Add, inside your subnet, this clause:
| Code: | | option routers 192.168.1.1; |
or whatever your router is supposed to be. |

Thnx ..
I added that entry and I still get the same thing.
ddns-update-style none;

Same exact error? The pertinent section is here:
| Code: |
/etc/dhcpd.conf line 4: no option named gateway
default gateway
^
|
This seems to indicate that on line four you have a section that says" default gateway" which is not a valid DHCP option. If you haven't sent the entire configuration lately, then this might be your issue. The routers clause is what defines the gateway for the subnet. |

I am STUPID....
I guess it would hlep if I statically assigned an IP to my nic <eth1=192.168.1.1>. Nic attached to the outside<eth0=dhcp> is setup for dhcp.
So I ran the command :
- ifconfig eth1 inet up 192.168.1.1
followed by
- service dhcpd start
And TADaw !!!
Starting dhcpd:
[root@localhost ~]#
So what's next ? |

Add some static hosts to the config, or install webmin and use the nice easy gui.
Example static host: | Code: | host laptop {
ddns-updates on;
hardware ethernet 00:0d:61:7a:27:7b;
fixed-address 192.168.1.2;
}

I guess not having the interface configured for IPV4 is going to put a dent in a DHCP configuration that only deals in IPV4.
I hate the gui configuration. It breaks down after a while somehow. Uninstall that turkey and use vim to configure everything. |

I realized that I didn't statically assign the IP to the nic on the LAN. So anyway you have to NIC's in your PC, right. 1) eth0 - DSL/Cable modem<this takes you to Internet> then you have the second. 2) eth1 - hub/switch < connects to the internal network via a hub> Well the nic connecting to the hub on the internal network had to have a static IP assigned to it. Even though you're running DHCP server on this PC, that particular card has to be statically assigned. All the other devices on your network will be automatically assigned. <ie..your 2nd or 3rd PC's...printer..etc.>
So after I statically assigned the IP I then ran the following commands:
- /usr/sbin/dhcpd < When you run this it will say it's listening to the device>
- service dhcpd start <IF the above is successfull this won't read as FAILED>
ANyway this worked in my case. |
