Ubuntu :: Configuring 9.10 As Client To Use Samba/LDAP Server For User Authentication?

Jan 18, 2010

how to make a new Ubuntu 9.10 box use our LDAP/Samba server for user authentication. Our Red Hat and Windows machines all use it just fine. I've been trying to use the auth-client-config and libnss-ldap packages for this purpose, but I must be missing something. I'm pretty green with LDAP, so this is my first time diving in... Is there a good How-To or step-by-step read on this? All of my searches lead me to setting up Ubuntu as the server, and that isn't what I want. I've also tried the steps listed in [URL] for the LDAP Authentication section.

Debian :: Configuring Lenny To Use DHCP?

Jan 4, 2010

I am working with a bare bones lenny that connects fine to an ADSL router using wireless ethernet and a fixed IP. I am trying to reconfigure to use DHCP but it isn't happening.

I'm using the following page as a reference... An introduction to Debian networking setup

ok I modified my /etc/network/interfaces file as follows...

# The primary network interface
allow-hotplug wlan0
iface wlan0 inet dhcp
dpkg --get-selections shows I have the following installed
dhcp3-client install
dhcp-common install

as I understand, that is all that is needed. However when I try to ping the router I get the error network unreachable. ifconfig does not have an inet addr. in the wlan0 section. dmesg | grep dhcp shows nothing at all.

Fedora Networking :: Configuring IPv6 (network) Tunnelling - Getting Only Internal Addresses From DHCP

Aug 25, 2011

I am trying to configure my IPv6 network. My computers are behind a Fedora gateway IPv6-configured, which is working great. But for computers inside my network, it seems I am getting only internal addresses from DHCP. Here is my ifconfig for an internal computer:

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.

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 Servers :: DHCP Server And DHCP Client Simultaneously?

Aug 4, 2010

I 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.

General :: Use A Kickstart File For Red Hat With No Dhcp Server?

Apr 6, 2009

I'm trying to do a red hat Advanced server 4 update 7 install using a kick start file on the network. 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. When i check the http access logs on the other server, it shows no access from the server receiving the install.I have tried adding an ip address to the install command. Such as:

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.
