We did something very similar to what you're asking about in #1 and #2 where I used to work. I used the setup for installing on systems but someone else did the initial setup. You need to look at two things: PXE and custom kickstart. I think Red Hat has some guidance on how to set up both. If not, Google. The idea is that the system that needs to get an installation is set to "boot from LAN" in the BIOS and the PXE server is also setup as a DHCP server on the same LAN segment. The system being installed does a normal boot from LAN which contacts the DHCP/PXE server. The DHCP/PXE server provides the boot image using tftp from the first install CD and a kickstart file. The kickstart file controls the installation as to which apps get installed. The setup we used let us pick from several different possible kickstart files for different configurations so there's room for customizing the process. Hopefully, that's enough of a start in the right direction that you can Google for the details. As to #3, the idea is to have the source of the ghost image setup for DHCP booting and not be bound to a particular network card (HWADDR in the ifcfg-ethX file). The target system gets the ghost image and then needs to reboot. When it boots, it gets a new IP address via DHCP. Cheers, Dave -- Politics, n.

Create a Yum repository for CentOS 5?
by Niki Kovacs 09 Feb '08

09 Feb '08

Hi, I'm using CentOS 5.1 on both server and desktops. I have a series of packages that I either rebuilt from CentOS SRPMS to modify them according to my needs (PHP for example), or that I built from Fedora Core SRPMS because they're not available on CentOS nor in the RPMForge repos (Seamonkey, MPD with libshout support, xmms-wma, ...). I want to create my own remote Yum repository for these packages, but I don't quite know how to achieve that. I've done something similar with Slackware and swaret before, though, so I sort of grasp the logic behind it. Is it possible to do that on a remote server where I only have FTP access? E. g. somehow create the repo locally on one build box, copy the whole tree over to the remote machine and then add some according file/stanza in /etc/yum.repos.d/ ? cheers, Niki

by carlopmart 09 Feb '08

09 Feb '08

Hi all, I need to setup a repo server to allocate updates for RHEL3, RHEL4, RHEL5 and CentOS5. Apart of mrrepo tool, I see that I can use reposync from yum-utils package and yum-rhn-plugin package to setup a mirror update server. But I can't to find yum-rhn-plugin under centos5 repo. Where is it?? Or I need to use package released from upstream vendor?? Thanks -- CL Martinez carlopmart {at} gmail {d0t} com

IPtables Possibility
by Jun Salen 09 Feb '08

09 Feb '08

Hi, I just wonder if I can replace PIX firewall with machine having IPTable as my firewall. I want to control our firewall but due to the lack of knowledge in configuring PIX, i want to replace it with Linux or BSD. I do not have the time now to learn the complexity of PIX and yet I want to know what happening in my firewall and control it as much as possible. Do you think it is justifiable for me to replace it? Can you please provide me your inputs? Thank you very much. junji aisalen.wordpress.com Linux Registered User #253162 CentOS User Send instant messages to your online friends http://uk.messenger.yahoo.com

CentOS 5.1 Core 2 Duo Install freezes
by Ken Price 09 Feb '08

09 Feb '08

Alrighty. I'm having a hell of a time and I need help. I'll try to give as much information as possible. ---------- HARDWARE ---------- MB: Supermicro PDSBM-LN2+ Intel 946GZ ICH7R + Intel® 82573 Memory: Crucial 512Mb, 1Gb, 2Gb modules matched to above MB. Processors: Intel Celeron 420 Conroe-L, 1.6GHz 512KB 64-bit Intel Core 2 Duo E6320, 1.86Ghz 4Mb 64-bit Intel Pentium E2140 Allendale (Dual Core), 1.6GHz 1M 64-bit Hard Disks: Various Western Digital and Seagate SATA Drives ---------- ---------- BIOS (Rev 1.0 as well as Rev 1.0a) ---------- Disabled Native Mode Disabled Native Mode with ACPI Enabled SATA Native Mode ---------- KERNEL PARAMS (singularly and combination) ---------- acpi=off, pci=nommconf, pci=bios, nohz=off, noapic, nolapic, pci=routeirq, maxcpus=1 ---------- ATA_PIIX loads at startup, sometimes ACPI depending on my BIOS settings. Always after verifying dependencies, and typically during the disk format process, the installation freezes. I get a "kernel panic - not syncing" in text mode. Single disks, dual disks, LVM, no-LVM, software RAID, even when disks are on a Promise SATA300-TX4. The single-core Celeron processors work fine, but none of the dual core processors work. I'm using 5 sets of hardware, so bad hardware is unlikely. I'm stumped. Anyone out there with similar problems and/or workarounds? Any ideas? -Ken

resolv.conf question
by Thomas Dukes 09 Feb '08

09 Feb '08

Hello, I have a centos 4.6 system acting as a router for my local network. I obtain my eth0 IP address automatically via DHCP from my ISP, sc.rr.com. If I add 127.0.0.1 to resolv.conf, it won't save it. I tried adding this to my dhclient.conf lease { option domain-name-servers 127.0.0.1; } The above is the only entry in the file. Don't know it caused it but my system locked up 3 times since adding this. Deleted the file and its fine. Any help would be appreciated. --Eddie
