Networking :: Configure A (openSUSE) Client To Dhcp To EBox DHCP Server - Lease An IP Address

Mar 25, 2010

I 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?

Mar 8, 2010

Currently I have my eth0 interface getting a DHCP address but at times the DHCP server will not be reachable. Sooo what I would like my server to do is if it cannot find a DHCP server assign a static address to eth0. Then start the DHCP service so it can then dish out some addresses.How can I do this? Surely it is possible

Ubuntu Networking :: Jaunty Server DHCP Renewal Fails Sometimes?

Jun 3, 2010

Ubuntu Jaunty Server connected via eth0 to a Billion residential ADSL router. I've locked the server MAC address to a specific IP in the router and set the DHCP renewal times to the longest possible times. For a certain number of days, the server will remain connected to the router, but then for some reason (the last time it was after about a month), the server loses it's connect and dumps into syslog the following:


Code:
Jun 2 17:10:15 defiant dhclient: DHCPREQUEST of 192.168.1.105 on eth0 to 192.168.1.254 port 67
Jun 2 17:11:26 defiant dhclient: last message repeated 5 times

Networking :: Configure To Use A Specific DHCP Server?

Jan 24, 2010

This is probably an odd request, but figured I'd ask in case someone knew. We have a lab that has the IP range 172.10.0.0/16 (255.255.0.0). The lab gateway/DHCP assigns an IP in the range of 172.10.0.2-172.10.0.254. I want to set up my own DHCP server on a specific range, for example 172.10.10.1-172.10.10.254. I create a new host fine, but since it's set for DHCP, it uses the DHCP server at 172.10.0.1. Is there a way to force it to use a different DHCP server on the client side? I realize that I can work around this with exclusions on the 172.10.0.1 DHCP server, or use iptables to deny DHCP requests to specific MACs, but wanted to know if there was an (easier?) way to configure the client to use the 172.10.10.1 DHCP server instead of the 172.10.0.1 server?

Ubuntu Networking :: DHCP Server Which Does Not Configure The Default Gateway Parameter

Jun 29, 2011

I need to place an Ubuntu machine on a network where I have a DHCP server which does not configure the Degault Gateway parameter (we don't want ordinary users to browse the internet). Is it possible to leave the machine using DHCP and define the Default Gateway manually (as in Windows XP i.e.)? How?

Ubuntu Networking :: DHCP Server No Longer Responses To DHCP Requests - Can't Ping Gateway

Oct 22, 2010

Back 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.

Ubuntu Networking :: Fails To Complete DHCP Transaction?

Feb 7, 2010

I know there are hundreds of similar questions about suspend on Ubuntu, but none of the fixes they use work for me. This bug is the only thing that stops me from using Ubuntu - I put computer to sleep (suspend to ram) and after resume I have no network. The only way to get network back is to restart.

Looking at the logs, it seems that NetworkManager starts, finds the device and then fails to complete DHCP transaction. I don't know what causes the problem, probably this line: "via-rhine: Reset not complete yet. Trying harder." Does anyone know possible reason for this? Here is the log:

Networking :: Debian/Squeeze Fails To Get DHCP Address On Startup?

This one has been bugging me for some time now. The network interface (as defined in Debian's /etc/network/interfaces file) fails to obtain an IP address from myuter. However dhclient br0 does.I'm using br0 since I run a XP virtual machine.network/interface changes are from a Debian howto on setting up the tap interface.As near as I can tell, the /etc/init.d/networking script basically calls /sbin/ifup -a. ifup is a binary.My /etc/network/interfaces file is:

Networking :: Configure Dhcp To Give Front Numbers?

How to configure the dhcp to give the front numbers, eg 192.168.1.10 first, then 192.168.1.11 and so on. Then on option domain-name-servers 8.8.8.8; how can I include second nameserver ? 8.8.4.4 See below for my dhcpd.conf

CentOS 5 Networking :: Unable To Start DHCP Client?

Jul 23, 2009

I have Centos 5 installed on a PC in the local network. I have installed the RPM dhcpv6-client-1.0.10-16.el5.i386.rpm on this PC to configure it as DHCP V6 client. The RPM was installed successfully, and I have done modifications to the following files:

1. /etc/sysconfig/network, set the networking to yes.
2. /etc/sysconfig/network-scripts/ifcfg-eth1 set the BOOTPROTO=DHCP.

Now the problem is when I start the client on this pc as dhclient, it throws the following errors, and logs out after some time. All the network configurations were lost and the PC gets disconnected from the network.

Ubuntu Servers :: Ubuntu Server Edition Was Unable To Configure DHCP During Install?

Apr 12, 2010

I am trying to install Ubuntu server edition on an old HP XT963 that recently came into my possession. I mainly just wanted to use it as a home file server and print server. I have been running ubuntu desktop on my laptop for a little under a year, but this is my first go at the server edition.

While ubuntu was installing it said "network autoconfiguration failed," I hit continue, thinking I could figure out how to configure it later. After lots of googling I still haven't figured out what exactly is wrong.

Code:
auto lo
iface lo inet loopack
after googling around I made it look like:

[Code]...

I would like to provide more information such as ifconfig and any other commands but I'm not exactly sure how I would do that without being able to copy/paste. I guess I would have the command dump the output to a file, but I'm not familiar with the -options this being my first time CLI-only.
