Re: [CentOS] netinstall problem -- corrupt alsa-utils-1.1.0-10.el6.i686.rpm?
Hello. In short: I cannot help concluding that there is something wrong with at least some centos mirrors. -- First, as I did not get any answer to the email below (about 3 weeks ago), I ask one question: is this list not the proper place to ask these types of questions (if so, please let me know of a better place) or perhaps was my email not properly formulated? -- Nevertheless, I made some progress. Before going into that, I try to summarize my problem: I tried to install CentOS with several installation media with the netinstall iso; The computers boot fine on the installation media; I choose the language (us) and the keyboard type (fr-latin1); then, at the "Installation method", I choose "URL" and enter http://mirror.centos.org/centos/6/os/i386/ I choose "Basic Storage Devices", "Paris" as the "nearest city in [my] time zone", the root password, "Use All Space", then click "Write changes to disk", and choose "Desktop". I then see a pop up saying "Installation Starting" with "Starting installation process", and, about a few seconds afterward (no chance to see any progress bar), an "Error" pop up that says: The file alsa-utils-1.1.0-10.el6.i686.rpm cannot be opened. This is due to a missing file, a corrupt package or corrupt media. Please verify your installation source. -- Now the new stuff. Last Thursday (Oct. 25), there was apparently a problem for this URL (at least from my location): http://mirror.centos.org/centos/6/os/i386/, so the installation process failed right away (I checked that I could not access it from a browser either). After a bit of googling, and out of despair, I tried using http://mirrors.sonic.net/centos/6/os/i386 instead of http://mirror.centos.org/centos/6/os/i386/ for the URL selected during the installation process. >>>> The whole installation completed without any problem <<<< The next day (Fri. Oct. 26), http://mirror.centos.org/centos/6/os/i386/ was back to life, but with it the installation failed as usual (alsa rpm issue). I tried again with http://mirrors.sonic.net/centos/6/os/i386, and... this time it also failed (same alsa issue). Then I tried ftp://ftp.free.fr/mirrors/ftp.centos.org/6/os/i386 and it worked just fine all along (installation successful). Today (Wed. Oct. 31), I try again with the 3 URL just above, in the same order, with the same results. So from my experience, as described above and in my initial email (Oct. 9), it seems to me that the most likely is that there is nothing wrong with my installation media (various centos netinstall iso files, written on 2 USB sticks and 1 DVD, with unetbootin or livecd-iso-to-disk, on different computers, which all fail in the same way), but that is something wrong with some centos mirrors.

[CentOS] netinstall problem -- corrupt alsa-utils-1.1.0-10.el6.i686.rpm?
Hello. I try to install from the netinstall iso file. Everything works as I expect up to the screen where I have to choose between "Desktop", "Minimal Desktop", "Minimal", etc. If I choose either "Desktop" or "Minimal Desktop", I have a pop up saying "Installation Starting" with "Starting installation process", and, about a few seconds afterward, an "Error" pop up that says: The file alsa-utils-1.1.0-10.el6.i686.rpm cannot be opened. This is due to a missing file, a corrupt package or corrupt media. Please verify your installation source. If I choose "Minimal", this is the same except that instead of the alsa*.rpm, it is iputils-20071127-24.el6.i386.rpm. I have successfully used this installation procedure in the past, literally tens times (last time in January). Since it says "verify your installation source", I have now tried again with CentOS-6.10-i386-netinstall.iso CentOS-6.9-i386-netinstall.iso on two different USB sticks, written with unetbootin and livecd-iso-to-disk on two different computers. I also have a DVD with some former CentOS version (perhaps 6.4). I have tried the installation on 3 different computers (on one of which the procedure worked in the past). Every time it is the same. NB: during the installation process, the URL I enter is http://mirror.centos.org/centos/6/os/i386/ Any "chance" there is a problem on the CentOS side? Otherwise, what could I be doing wrong now?

Re: [CentOS] netinstall
http://www.if-not-true-then-false.com/2011/centos-6-netinstall-network-installation/ This is a tutorial that will guide you through and points to the correct URL for package repositories and to the correct install.img file. Sure, but the install.img file at the package repository isn't more correct than the one on the netinstall CD. They are identical. The guy who wrote the tutorial obviously encountered the same problem but wasn't aware of the file on the CD and suggested this workaround. I actually used this process several time and never encountered any issue of this type. BTW, I got the system running. But I fear that I'll have to install it several times again because I'd like to experiment with virtual machines and LVM. It's very likely that I break something since I have no experience with them. Therefore it would save me some time if I don't have to download a file which exists on the CD already. For your time consuming concerned about breaking your VM, you can create one and then just clone it. This way you will always keep a fully working copy of your CentOS VM. Another thing: Even if I can use install.img from the CD, at least when I have to install packages, I have to specify an URL to a repository. Documentation proposes mirror.centos.org . Is there a reason why the installer doesn't offer the mirror URL as a default? I ask because I have only one machine and whenever the installer asks me for an URL, I have to abort and boot a system which provides a web browser in order to read the documentation, write the URL down on paper, and start the installer again. Well, I sometimes have the impression that I'm the only one in the world who doesn't have a mobile phone with a built-in web browser. :) For the default settings about mirror.centos.org it is beyond my scope ;) Maybe not by default but an option stating Do you want to get the sources from an official CentOS mirror. But anyway, mirror.centos.org isn't the hardest URL to remember. -- *Yanis Guenane* ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] netinstall
I'm a newcomer to CentOS. Fedora 14 was the last Fedora version I managed to make work. Fedora 16 I couldn't install at all. Fedora 17 installed, but I couldn't make it work right. I'd been trying to do media-less installs because Fedora wouldn't read my DVDs anymore. What directions I could find for installing CentOS without media were not all that clear to me, so I did some guesswork informed by some of the Fedora documents. I used the following grub stanza: title Install Centos 6.2 from net install iso find /centos/vmlinuz root (hd1,9) pause paused kernel /centos/vmlinuz method=http://mirror.anl.gov/pub/centos/6/2/os/i386 initrd /centos/initrd.img The find and pause were not really necessary. I think vmlinuz and initrd.img were copied from a net_install.iso file. Much to my surprise, it worked the first time. -- Michael henne...@web.cs.ndsu.nodak.edu On Monday, I'm gonna have to tell my kindergarten class, whom I teach not to run with scissors, that my fiance ran me through with a broadsword. -- Lily ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I'm not talking about the packages but about the file install.img. This file *IS* already on the netinstall CD and it's exactly the same as the one I had to download.

Hi there Jeff, well I can only tell about the very early times of Linux with kernels below 1.00, around 20 years ago ... ;) Don't know how this is going to work with CentOS nowadays, my labor is just building yet. So, back to the context, there are three ways afaik though bringing CentOS up: 1) Loading the network module for your Acer after netinstall has come up from any device you can see until then, perhaps an USB drive. That might be the 'easiest' way. In former times this had to be done f.e. for SCSI-drivers via good old YaST ;) Of course you first have to download the driver with a running system from a CentOS-mirror. 2) Not using netinstall, but I guess you have no CDDROM built in. 3) Perhaps another solution could be first installing another system (debian?) and then creating a bootable device with all needed stuff on.

I re downloaded the ISO and its all working flawlessly now, off course I won't go into the details of the firewall issues and the actual NFS configuration, I will create a video to help people out doing this install via NFS. Anyone recomended a good screen capture application to do this task, after I create it I will posted in youtube for all to see it. Thank you all and don't forget to check all your sha1sum or md5 keys from DVD or CD ISO, it looks like we can't trust the actual mirrors. Thank you again. NFS install is mega fast in a 1Gbps network. My hard drive is the slow horse now.

Re: [CentOS] Netinstall NFS using local server.
ok, playing around with netstat I figure all the ports that need to be open in iptables for this thing to work, I figure having the firewall down was too big of a risk so why not figuring out the ports and opening them in iptables and sharing the knowledge with you guys. The following ports are to be open: 111 tcp/udp 32803 tcp/udp 32769 udp 892 tcp/udp 875 tcp/udp 2049 tcp/udp If I only mentioned tcp or udp after the port it means either or both, if you see one/two it means both protocols must be enable. Also make sure you tweaked around you /etc/sysconfig/nfs file, I noticed that by default you need to have some of the stuff from there un-comment for it to work, I will post my file so you can use it as a skeleton to change yours. If you have any questions let me know and I will try to help you out. My nfs config bellow ( this only applies to Centos 5.5), I didn't test in another release.

This is what my exports file looks like: [r...@zeus DVD]# cat /etc/exports /centos-media/centosdvd64 10.14.10.0/255.255.255.0(ro,sync,all_squash) /centos-media/centosdvd32/DVD 10.14.10.0/255.255.255.0(ro,sync,all_squash) After doing so, I also modified the entries under IPtables to allow traffic in 111 and 2049 at the UDP/TCP level and restarted the service as shown bellow. Oh, dear. This sort of thing is requirement is why you simply run a light FTP or HTTP server and make it accessible that way. It's nominally slower, but the difference is hardly noticeable.

Can someone tell me what am I missing? I have spend all day trying to get NFS working in the local vlan, i know that all ports are open within the vlan at the routers level. Any clues? What is the actual path you are giving it? Are you looking at the top of the relevant NFS exported directory? And did you pout all the contents of the ISO image there, are are you doing somehing stranger? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Netinstall/kickstart issue
When booting the 5.3 i386 netinstall iso and performing a ks install, the server pauses for a very long time at the Retrieving images/stage2.img screen and the apache log where the http served tree exists shows it looking for: ...File does not exist: /var/www/html/CentOS/images/product.img ...File does not exist: /var/www/html/CentOS/disc1 multiple times until finally it gets going. This tree was a dvd copied to a directory being served out. Any ideas? Thanks! jlc ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
