View 1 Replies View RelatedUbuntu Networking :: DHCP Server No Longer Responses To DHCP Requests - Can't Ping Gateway
Oct 22, 2010Back in April I set up a Ubuntu DHCP server and a multiple VLAN network [URL] to migrate our various servers, workstations, etc off the 192.168.1.1 /24 network that everything was on because we where running out of address space. I built out the new network and everything worked great except our AD server would never get an IP address from the DHCP server (static reservation) and even if I set the IP statically on the AD server it couldn't ping the gateway and noone could log in. After several attempts to resolve this, including bringing in outside help, we where never able to figure out what the problem was.
Now 6 months later I have time to revisit the issue without effecting the live network. I used Acronis and imaged the AD server last Friday, cloned it on to another box with the same hardware, and put it up on the new network that's been sitting unused for the last 6 months. Today when I statically set the IP on the AD server (which is what I want) it connects and I can ping it's gateway 192.168.1.1 and all the way across vlans to a test sales agent workstation at 192.168.8.xxx on vlan 800 but only if I statically assign the agents station an IP address. When I try to get an IP address via DHCP it fails as destination unreachable. Nothing has changed in the last 6 months on the DHCP server but now it for some reason can't ping its default gateway 192.168.1.1. All of the config files are the same as they where left from the post linked above aside from the vlan id's used where changed from 1's to 100's (i.e. vlan 3 is now vlan 300) /etc/network/interfaces
Code:
auto lo
iface lo inet loopback
auto vlan100
iface vlan100 inet static
[code]....
why it can't reach the gateway, when I do a tcpdump I can see the DHCP requests come in on eth0 but the server never responds and I'm pretty sure its because it isn't "seeing" them since it thinks there isn't a network connection but I don't know how to trouble shoot to find out where the problem lies.

Networking :: Configure A (openSUSE) Client To Dhcp To EBox DHCP Server - Lease An IP Address
Mar 25, 2010I am puzzled with trying to configure a linux (openSUSE) client to dhcp to eBox DHCP server. I am using dhclient to lease an IP address with dhclient eth0 -s 10.45.48.108 and get a response
openSUSE11232CL1 dhclient: DHCPDISCOVER on eth0 to 10.45.48.108 port 67 interval 4
openSUSE11232CL1 dhclient: DHCPOFFER from 10.45.48.108
openSUSE11232CL1 dhclient: DHCPREQUEST on eth0 to 10.45.48.108 port 67
openSUSE11232CL1 dhclient: send_packet: Network is unreachable
openSUSE11232CL1 dhclient: send_packet: please consult README file regarding broadcast address.
The server reports eBox141 dhcpd: DHCPDISCOVER from 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
eBox141 dhcpd: DHCPOFFER on 10.45.200.2 to 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
I interpret this as the server receives the request and the client accepting it but the lease does not last long and the connection breaks. what this could be and why the connection breaks? Or my undestanding is totally wrong on how it works and should work? And BTW, where is that README file that's referenced in the message I receive on the client?
Ubuntu Networking :: If DHCP Not Available - Fallback And Start DHCP Server?

View 2 Replies View RelatedUbuntu Servers :: DHCP Server And DHCP Client Simultaneously?
Aug 4, 2010I have an embedded device for which I've created an html configuration page. This page allows you to set static IPs, dhcp, and can scan for wireless devices.My problem is that in order to access the device it requires that it runs as a dhcp server otherwise people are not assigned an IP and so can not access the embedded devices static IP. (This config page is for the laymen and so they are not the type who are able to set up their own static IPs). One of the potential options is to have the device connect to the network on eth0 acting as a dhcp client. However this prevents me from running a dhcp server.One solution I can think of is running a dhcp server only if it doesn't detect another dhcp server running on the network.

Aug 25, 2010I would like to install CentOS 5 to a NFS root. My NFS server is not CentOS. Is there a way to tell Anaconda to use NFS for root? Is there a way to mount some NFS space at /mnt/sysimage and get Anaconda to use it? I supposed it should be possible to either move an already installed CentOS system to NFS and rebuild initrd with a rescue boot or it might be possible to do a manual install using rpm directly to install the packages onto some NFS space. The first would require a local disk temporarily. The latter would be an excessive bunch of tedious work.

Aug 1, 2011After a fresh install of Ubuntu 11.04 (from 10.04) and spending several hours trying to figure out why the ad-hoc connection between my two computers (Fedora14 <-> Ubuntu 11.04) no longer worked - it had worked fine for almost 2 years with 10.04 - I've finally concluded it was a DHCP problem. This realisation (which was slow in coming!) dawned on me when I reversed my setup and configured the Fedora box as the DHCP server and everything was suddenly working perfectly! A quick internet search threw up an installation file called "isc-dhcp-server" which other Ubuntu 11.04 - related forums are also complaining about. My problem is that this file, although available in the repository, is not even installed!!!
It seems unlikely that the developers forgot to include DHCP support, so I hope someone can point me in the right direction.

The server with the kickstart file and dvd contents is on the same subnet as the server receiving the install. We have done it before in the past just fine using:linux nofb text ks=http://serverip/path at the boot/install screen. After that the ip address info is entered manually and the kickstart does its thing. When doing this with update 7, the install acts like a regular install.

Jul 2, 2010The DHCP server on a network I use specifies a DNS server that I do not want to use. Is there a way to continue to use DHCP but to modify the provided information or to "blacklist" one (of the three provided) DNS servers?
The client in question is running Ubuntu 10.04. Networking is managed by NetworkManager but I'm not wedded to that. In fact, I don't like it and wouldn't mind a reason to use something else.

View 1 Replies View RelatedGeneral :: Windows Clients Not Using NTP Server Provided Via DHCP?
May 31, 2010I have a network consisting mostly of Windows Vista and 7 clients and an Ubuntu server. The server provides both the DHCP and NTP services through dhcp3-server and openntpd. In my dhcpd.conf, the subnet is declared as follows:
subnet 10.10.10.0 netmask 255.255.255.0 {
range 10.10.10.10 10.10.10.200;
option broadcast-address 10.10.10.255;
option routers 10.10.10.1;
option ntp-servers 10.10.10.1;
The clients don't seem to be using the NTP server though. When I capture the network traffic with Wireshark during the DHCP process, I also see no mention of the NTP option in the DHCP offer message. I am not quite sure if the clients would have to specifically request that option to receive it or if I have to make another configuration to offer the option.
General :: Query A DHCP Server To Get The Local DNS Servers?

I want to change them back to the local DNS servers but I can't find an obvious/easy way to get those address short of a) reconfiguring the router's network to DHCP them (would rather not interrupt everyone) or b) calling their tech support (kill me now!). Is there a command line tool/command I can use to query the DHCP server on the external NIC to see what DNS servers it would set me up with w/o munging my existing setup?

Server :: DHCP Server On CentOS 5.5 Not Working - When Connect Any Devices To Eth1 They Don't Get Any IP
Dec 2, 2010I'm no expert on DHCP. My problem is that i have a CentOS 5.5 server on which i want to install a DHCP server. I have two NICs where eth0 has access to the internet and where eth1 should act as an DHCP server.
I have installed dhcpd and this is how my dhcpd.conf file looks like.
Code:
ifconfig looks like this
Code:
When i start dhcpd on eth1 i get no error messages but when i connect any devices to eth1 they don't get any IP. I cant find anything in any logs about devices trying to get an IP address. I dont have any firewall rules in iptables.
