[CentOS] making a new initrd
Hi, I built a new kernel for C7 that contains the required driver for a new motherboard we have here. I'd like to take this initramfs and rebuild it/modify it so that it is suitable for pxe booting. I have tried dracut -v --force --add "anaconda" initramfs.img # results in an image that is too large for tftp Or dracut --nofscks --nomdadmconf --nolvmconf --xz --no-early-microcode -m "anaconda" --force initramfs.img # kernel panics What steps should I be taking to create an initrd image suitable for pxe boot ?

Hey Rodrigo,
Thanks for your reply.
Well those errors are pulled from the Chrome developer tools.
I notice if I do a GET on that file using both all lower case as well as
the upper case that's in the URL I get the same result:
[root@aozwsls00019la apache2]# GET

This is how that file looks on the command line. I made a symlink to
account for the change in case, because I realize that's relevant:

-rw-r--r--. 1 daemon daemon 128 Aug 27 12:22
/var/www/mycompanyStore/images/altImg.png
Still not sure why I'm not able to do a GET on that and those other files.
Appreciate your input tho! And any other advice is certainly welcome!

Hey guys,
Just have a question about apache. Hoping to get an opinion on this.
I've just setup a site under apache 2.4.
And made sure that the document root setup in the vhost for the site I'm
serving has permissions for the apache user. Yet some of the files are
throwing a 404 error in a browser even tho they are clearly present and
accounted for on the file system.
For example, I'm getting this error:
(index):1 GET
http://stage.theshopatmycomany.com/mycomanyStore/images*/altImg.png
404 (*Not Found)
(index):1 GET
http://stage.theshopatmycomany.com/mycomanyStore/images*/Jimmy_485x1215_R2.jpg
404* (Not Found)
(index):1 GET
http://stage.theshopatmycomany.com/mycomanyStore/images*/Jimmy_792x802_R2.jpg
404* (Not Found)
(index):1 GET
http://stage.theshopatmycomany.com/mycomanyStore/images*/Jimmy_792x413_R2.jpg
404* (Not Found)
And yet as I mentioned all those files are definitely there on the file
system:
[root@aozwsls00019la apache2]# ls -l
/var/www/mycomanystore/images/altImg.png
/var/www/mycomanystore/images/Jimmy_485x1215_R2.jpg
/var/www/mycomanystore/images/Jimmy_792x802_R2.jpg
/var/www/mycomanystore/images/Jimmy_792x413_R2.jpg
-rw-r--r--. 1 daemon daemon128 Aug 27 12:22
/var/www/mycomanystore/images/altImg.png
-rw-r--r--. 1 daemon daemon 260983 Jul 16 14:03
/var/www/mycomanystore/images/Jimmy_485x1215_R2.jpg
-rw-r--r--. 1 daemon daemon 126628 Jul 16 14:00
/var/www/mycomanystore/images/Jimmy_792x413_R2.jpg
-rw-r--r--. 1 daemon daemon 222568 Jul 16 13:56
/var/www/mycomanystore/images/Jimmy_792x802_R2.jpg
And all those files have the correct ownership for apache:
[root@aozwsls00019la apache2]# egrep -i user|group conf/httpd.conf |
egrep -i -v -e '#' -e log -e module
User daemon
Group daemon
All the files are owned by daemon:daemon!! So why on earth are these
files
giving a 404?
This is my virtual host for the site:

[CentOS] selinux and tinydns
Hi all, tinydns starts up fine, selinux reports no issues (now after a day of clearing errors). If I turn selinux back to permissive in /etc/sysconfig/selinux, and reboot, tinydns responds to queries. If I turn selinux back to enforcing and reboot, tinydns does not respond. Monitoring /var/log/messages shows no errors from iptables/shorewall or selinux. The only way I can find an error is performing the following:- netstat -npl | grep tinydns # gives me the process id strace -f -p process id From this I can see that tinydns is reporting an error of:- recvfrom(3, 0x606720, 513, 0, 0x7fffc7321ec0, 0x7fffc7321edc) = -1 EACCES (Permission denied) I've got setroubleshoot set to send me an alert on first occurrence of an issue, so far none received.

In 6.x it wants an interface as a parameter. What is the appropriate way to find which of some number of of interfaces are connected? Better yet, what is the least typing to get the mac addresses of those interfaces? Dumb question: in /etc/sysconfig/network-scripts, do the ifcfg-* have HWADDRs? They do, but the case I want to cover is where an existing server is cloned, or the disk has been moved from a failed chassis to a spare. And in this case the existing files will be wrong, and the nics will be named more or less randomly. Assume the hands-on operators don't know much about linux and you can't actively help until they get at least one of the right IP's on the right NIC. With 5.x I'd use mii-tool to find the connected interface (connecting one wire at a time if necessary), then ifconfig on that interface to get the hwaddr, then edit that into the ifcfg-* file for the names I want the active NICs to have, and reboot. That's awkward enough to ask someone to do who already prefers windows, and it looks like it just got harder by having to explicitly run mii-tool for each possible interface (and we always have 4 to 6 per box). There has to be a better way. I thought 6.1 was going to have a new NIC name convention but I haven't had time to look into it and have to make something work now. Your situation is the textbook usecase example for biosdevname (http://linux.dell.com/biosdevname). It is a way to consistently name the network devices according to their physical location in a computer. For example, a typical NIC would not have a name eth1, but p2p3 (which means port 3 of the NIC in PCI slot 2) or em2 (which is 2nd ethernet port on the motherboard). So once the hands-on operator plugs a cable into a particular port, you immediately know the corresponding interface name that the system will use for that connection. And in addition, this is MAC-address independent, so moving the hard drive from one box to the other requires basically no reconfiguration (as long as the operator plugs the same cables into the same sockets). The biosdevname was first introduced in Fedora 15 (http://fedoraproject.org/wiki/Features/ConsistentNetworkDeviceNaming), ie. only after RHEL 6 was already rolled out. Apparently, it has to cooperate intimately with the kernel, udev, initscripts, dracut, anaconda, kickstart, etc., --- so it is not just a userland app which one could yum install in a trivial way. Therefore, somehow I doubt that CentOS 6 will ever see biosdevname implemented (maybe in the CentOSplus kernel and a use at your own risk label?), since it involves too many system changes and breaks backward compatibility. But RHEL 7 is almost certainly going to have it, since this is actually the proper (and permanent) solution to the problem you have. I thought I saw it mentioned in release notes for RHEL 6.1 but it said something about support being limited to certain Dell models. I'm not sure it is going to be perfect anyway, since most of the machines in question have Broadcom NICs on the motherboards and the ones we actually use are on Intel cards that may not exactly match types or slot positions. But I'd settle for something that had something to do with the slot position... http://www.pkje.net/meander/?p=115 - this may help on the device ordering for 6.x if you know the mac addresses then you can fix the names of the interfaces ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Do you have an exclude=*.i686 someplace in your yum setup.

However i got the impression it was something in the same category like tinyca or pyca. Perhaps it is based on the code of RHCS, and all documentation is just some wiki pages.

But i would like to have some hands-on experience before, and not get all my information from paper. OpenCA has also quite some nice docu (but doesn't live up to it), and used to be included in some distro's.

Re: [CentOS] HW issue during instalaltion
We tend to use CentOS for our desktops as well, hence the request to this mailing list. We do not wish to have Ubuntu installed.

I added an Intel Ethernet card to get over the Marvell Ethernet issue, and a NVIDIA 8600GT card. I forgot to add I used no additional driver disks to get Vista to see the disk. Try Ubuntu, you probably wouldn't need additional driver disks to get it workin' either. CentOS is a server oriented distro, not a desktop distro. Hardware differences between desktop and server are almost night and day in many cases. The system you link to is most definitely a desktop class system. Or perhaps Fedora, though I'm not much of a fan of the short support cycle for Fedora(assuming it's still 6 months). With Ubuntu(and possibly Fedora) you get the added advantage of tons more packages than what is included with CentOS/RHEL without having to resort to problematic 3rd party repositories or crazy yum configurations to try to keep a sane installation running. CentOS works great for what it's built for. nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
