CentOS 5 Networking :: DHCP With LDAP Backend Support And DNS?

Jun 5, 2010

using the LDAP as storage of hostnames/IPs/MACs for the DHCP server on CentOS.Also once the IP is allocated via DHCP to the hosts,it would be useful to insert such host into the DNS. (BIND? dnsmasq?)I've found this link [URL] which deals with a patch for the ISC DHCP package, but I don't think this is actually up-to-date.

CentOS 5 Networking :: LDAP User Can't Login Remotely By SSH On LDAP/Samba PDC?

Sep 8, 2009

I installed CentOS 5.2 and then run yum update. I configured this server as LDAP/Samba primary domain controller. LDAP seems to be OK and for testing I am able to create users with:smbldap-tools useradd -am usernameI can ssh into the server as root and also as a Linux user which was locally created in the server. But ssh into the server as LDAP user fails (from a Fedora 11 machine) with "Permission denied, please try again", prompting again for password.Some data:

CentOS 5 :: Anaconda Does Not Support DHCP Option 121 / Resolve This?

Nov 29, 2009

Following situation:
I'm trying to make a network-installation of my rootserver with CentOS 5.4 x86_64.
This server is hosted by 1and1 a company of the united internet group, which is a big player in europe.
The network environment of 1and1 is providing classless static routes via dhcp by using the dhcp option 121.
If i'm right anaconda does not support this dhcp option 121 and therefore does not "ask" for the routes.
Without the routes configured the traffic does not get through and the network installation fails.
An installation from fedora12 (anaconda 12.46) works without any problems.

Is there someone in the dev team that can patch or backport it?

Security :: MS Supplicant To Work With Freeradius And LDAP Backend?

Jan 13, 2011

I have been battling with FreeRadius with LDAP backend and Microsofts built-in supplicant.

If so can you point me in the direction of some good walk through?

CentOS 5 Networking :: Setting Up Name Resolution Via LDAP?

Apr 27, 2009

I'm setting up a LDAP server to centralize the admin of a bunch of Centos 5.2 servers. I've got the LDAP server set up. I've got my client machines reading their autofs mount tables from LDAP. Now, I'd like to get name resolution working via LDAP.

Here's what I have so far:

1) /etc/nsswitch.conf contains the line "hosts: files dns ldap"

2) /etc/openldap/ldap.conf has URI and NSS_BASE_HOSTS set up to indicate root of "hosts" subtree in LDAP database.

3) "hosts" node in database is an "orginizationalUnit" object.

4) Below "hosts" I have a number of "ipHost" nodes defined with "cn" set to host name and "ipHostNumber" set to host's IP address

This setup doesn't work. Attempting to ping a host by name locks up. If I take the "ldap" keyword off of the "hosts:" entry in the nsswitch.conf file, the ping then returns immediately with "unknown host".

I'm surprised that there isn't better information available online on how to do this. I've found bits and pieces, but nothing concise. how to get name resolution working through LDAP?

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.

CentOS 5 Networking :: DGE-530T Will Not Get IP Address From DHCP Server

I am attempting to get this network card running under CentOS 5.2 but have had no luck. Some sites say to use the sk98lin driver, others the skge, which I can't find at all. I have tried multiple versions of the driver in rpm but none seem to work. The card shows under the network manager but will not get an IP address from the DHCP server.

Here are the outputs for this card.

CentOS 5 Networking :: Spontaneous Static IP To DHCP Switch?

Jan 7, 2011

I had something I think if very odd happen to one of my computers at work today, it appears to have spontaneously switched from having a static address set to getting its address by dhcp.this is a small office with a mix of mostly linux servers and desktops with a few stand alone windows computers, mostly notebooks. Most of the desktop computers get their address by dhcp, they all have NIS /NFS for remote mounted home directories (interchangeable desktops so anyone can log in at any desk). The particular desktop computer in question here has a shared printer on its parallel port, so has a static IP. Yesterday a UPS in the server rack died, after pulling it and plugging things back in and restarting the servers, it was easiest just to reboot all the desktops, everything came up ok including the desktop in question, and the printer did work.

Today I pulled the oversized UPS from this desktop to replace the dead one, and put a more appropriately sized one in its place, shut the servers down again, rebooted, etc,About an hour later someone tells me the printer is not working on the desktop, and after a lot of searching I find this desktop has the wrong IP address, I ran system-config-network and it showed the address was set to dhcp, I changed this back to the correct static IP and things seem to be working ok now.

CentOS 5 Networking :: Dnsmasq Dhcp - DNS Server Does Not Respond

Jan 9, 2011

I got a CentOS server setup as a dhcp server using dnsmasq. I followed this guide more or less: [URL] So, the problem seems to be concerning the DNS server on the clients. In windows I get the "limited connectivity" icon for the network, and when I select troubleshoot it says the DNS server does not respond. Issuing 'ipconfig /all' clearly shows the IP of the CentOS machine as the DNS server, which should be correct, yes?

ETH0 is working as WAN connection and that works great.. no problem with the WAN connection at all on the CentOS machine. ETH1 has the IP and mask When starting eth1, it sometimes says that it can't start eth1 because the IP is already in use.. but that is most certainly not the case. Maybe there's some kind of issue here that messes with the DNS? What's mind boggling is that it works great on a linux machine (dhcp client) and on a windows xp machine. but it does not work on the windows 7 laptop and a vista laptop and a pda device.

CentOS 5 Networking :: DHCP: Option Domain-search (119) Not Supported?

Oct 14, 2009

I have an issue with the DHCP clients in a lab environment I am building. The lab is in a dns subdomain but the clients should be able to resolve any machine in the lab subdomain or the parent by using just the hostname. According to everything I have read, the client resolver should do this automagically, trying first the naked hostname, then the FQDN, then walking up the tree of parent domains. But it doesn't.

So I thought I'd just have the dhcp server set the domain search list to include both the local and parent domain. But adding "option domain-search" to dhcpd.conf causes dhcpd to fail on start up. Does the current version of dhcpd in CentOS 5.3 really not support this option?
