Blasphemous? any support for a REPO of current edition BIND, et al (e.g., BZ561299)?
by Larry Vaden 16 Feb '11

16 Feb '11

Hello CentOS Community Members, What is RH's be-all end-all justification for staying with an ancient code base for such important programs as BIND et al? A similar problem (to BZ561299) was first reported five (5) years ago on the isc.org mailing list. Is there any support among the CentOS community for a REPO of current vintage for such important functions as BIND et al? That question is based on the presumption that time is taking us to a more complete and correct implementation of the basic functions like DNS. IOW, is CentOS philosophy of tracking RH so nailed-to-the-wall that it is blasphemy to propose a REPO of current editions of certain very important functions? kind regards/ldv A quote from a long term mentor now at Internet2: "It's fundamentally wrong for RedHat to attempt to backport security patches for such a fundamental service. I'd cuss a blue streak about this point, in fact, except that I don't want to trigger the anti-cuss features at Dr. Vaughn's place of employment." === Reported: 2010-02-03 05:32 EST by Duncan (see https://bugzilla.redhat.com/show_bug.cgi?id=561299): Additional info: Works fine in Fedora 4,8,9 and 11, Red Hat Enterprise Linux ES release 4 release 4 (Nahant Update 8) and Red Hat Enterprise Linux Server release 5.1 (Tikanga) Fails in 5.4 and Fedora 10.

Authentication Problems
by James Bensley 16 Feb '11

16 Feb '11

Hi List, We have a CentOS VPS running a web site in a DC far away. The chap that dev's this site told me he couldn't SFTP in yesterday, his password was being rejected (I went to his desk to confirm and saw it was telling him the password was incorrect but neither him nor me had changed it and we are the only two with access to this VPS). So I logged in as root and reset his password, be he still couldn't log in (same problem, claiming the password was wrong). [root@server ~]# passwd webdevuser Changing password for user webdevuser. New UNIX password: Retype new UNIX password: passwd: all authentication tokens updates successfully. I tried to SSH in as the web dev user and it wouldn't let me in. Returning back to my root console window; [root@server ~]# su - webdevuser [webdevuser@server ~]# passwd Changing password for user webdevuser. Changing password for webdevuser. (current) UNIX password: passwd: Authentication token manipulation error Firstly; I am stracthing my head as to why his password was no longer working in the first place? Secondly; Why I can't reset it? Googling around many people suggest there is a discrepancy between the /etc/passwd and /etc/shadow files and by deleting /etc/shadow and using pwconv to recreate shadow and the same for /etc/groups, deleting gshadow recreating it with grpconv will solve the problem but I still can't login as the web dev user. Any ideas anyone? -- James. http://www.jamesbensley.co.cc/ There are 10 kinds of people in the world; Those who understand Vigesimal, and J others...?

Creating floppy image without root permissions?
by Kwan Lowe 16 Feb '11

16 Feb '11

Hello All: I've recently had to provision some RHEL and CentOS VMWare instances. There was no network connectivity so I had to use a kickstart floppy and DVD iso rather than installing from our repository. To create the floppy I used the following: As root: dd if=/dev/zero of=floppy.flp bs=1k count=360 mkfs.vfat floppy.flp mount -o loop floppy.flp /mnt/floppy cp base_kickstart.ks /mnt/floppy/ks.cfg umount /mnt/floppy It works, but now I need to automate the process and have to do with without root access. Is there a way to create a floppy iso with a single file without root access? I looked at fuseiso, but it appears that it still requires some root permissions.

Virtualization supporting 1000Mbps nics?
by Smithies, Russell 16 Feb '11

16 Feb '11

I've got xen-3.0.3-105.el5_5.5 running on Centos 5.5 and all is running smooth but I notice that any VMs running under it only have access to Realtek RTL8139C at 100 Mbps nics. We have 4 x 1G nics configured in a port channel so I'd really like to be able to give my VMs 1000Mbps nics. Does anyone know if this is possible and how to do it? If not, does KVM support faster nics because at this point it would be fairly simple to change.

Hi, I've a specific need for hotplug but found Centos doesn't ship it with the kernal and that such tasks are handled by HAL. Any one have ideas on how to get hotplug functioning in Centos 5.5? Thanks in advance, - aurf

Insert the second CD of an install
by Mike VanHorn 15 Feb '11

15 Feb '11

Using CentOS 5.5 x86_64. I am trying to install software that comes on two discs. I can start the install just fine, but when it comes to taking out the first disc and putting in the second, the system won't let me eject it. I remember reading something on the internet once about something needing to be enabled to allow this to work, but I can't find it now. Does anybody have a clue as to what I might be looking for? (Yes, the work around is to just mount both ISOs and not use real discs at all, but as administrator I understand that process and my users won't. However, they are familiar with the process of inserting disks.)
