View 3 Replies View RelatedI am working on setting up a bind 9 nameserver that will be responsible for serving up DNS records for my internal network and publicly for my web server. My configuration is below:
Firewall Gateway (Ubuntu Server 9.10) ---> switch ---> internal servers (ubuntu server 9.10 and mac os x server)
The internal servers are all on the same subnet, so DNS, web and mail will all be on the same subnet of private IPs. Each internal server is mapped with SNAT to a public IP address. And the DNS server only has port 53 forwarded to it.I am trying to figure out the best way to set up my nameserver so that it can provide records for my internal servers based on private IP addresses, and then provide records to the public for my internal servers based on their public IP addresses. I had a few questions on this:
1) Is this the correct way to think about my setup, or is this typically done in another way?
2) Does anyone have recommendations on the specific configuration I should follow?
3) Are there specific references I should look into as well?
Is it possible to setup dhcp server in such a way that even if a client disconnects for a short period of time (5 - 10 minutes) the dhcp server keeps that address for that specific client and lease it back. Tracking can be done using the mac address of the client.

Is there a way I can modify the array to RAID 1 without a risk of data loss? I'm glad I caught this before I setup any other services. I've only setup smb so far...

I try to set up a 5 nodes cluster and a shared Coraid Storage with conga but it fails with "Shared Storage Support" checked.The message is:'A problem occurred when installing packages: Packages of set "Clustered Storage" are not present in available repository' and it is shown under every node on the next sceen after I submit.The pc where conga runs is on the same subnet (192.168.xxx.xxx) and it has the same /etc/hosts of the other nodes.In that pc runs a proxy too and the nodes go out through it (that pc has 2 NICs)Every node (2.6.18-128.1.14.el5-xen-x86_64) is patched whith the last yum update (this morning) the same is for the pc (2.6.18-128.1.14.el5).Every node has 4 NICs , 2 NICc towards the storage the others in bonding towards the WAN.Every node is exactly alike, they have been installed with the ks.cfg generated from the first node and they all have the support for Clustering, Virtualization, and Clustered Storage.

View 1 Replies View RelatedHere is a thought experiment:
1. Copy vmlinuz and initrd.img from isolinux subdir into /boot
2. Adjust grub.conf to boot to that kernel
3. Reboot to setup
4. Format /boot (actually '/' ) during "fresh install"
5. Proceed with the installation-over-network
I see two possible outcomes:
1. The setup fails to reformat the drive, because it is "in use" by boot kernel
2. The partition is not "in use" and the installation succeeds
Why? Old cluster with broken CD-drives, lacking USB, and no separate /boot partition.
I'm wanting to setup a file server for home. I'll probably use the following: Ebox, Firefly Media Server, TorrentFlux I'm still not sure about how to go about redundancy for the store, possibly software RAID 5. ZFS would be cool but the linux support through FUSE and large memory requirements are a bit of turn-off. I'm also not sure how to go about supporting TimeMachine on my new Macbook Pro. I've seen a couple of old guides on the web discussing Netatalk and Avahi but noting new.
I'm thinking I'll probably use a spare 2.5" 80GB SATA drive for the OS drive, and then probably 4x2TB HDD (for 6TB of useable storage in RAID 5). I'm not sure about what mobo and cpu to use yet. I was originally thinking to go with an atom based Mini-ITX mobo but to get one with 4x SATA ports is hard enough, let alone trying to get one with 5-6x (1 for OS and 4 for data) so I'm thinking maybe I should get a low power Intel or AMD based Micro-ATX mobo with 6x SATA. I'm also thinking I'll setup CrashPlan for online backup from the server (plus directly from my Macbook Pro and my Desktop).
I have been using SLES 10 SP1 so far with about 6TB Raid system without problems.I have upgraded the OS to CentOS 5.3 i386 and I have noticed the kernel can not recognize raid system larger than 2TB.Is there any parameters that I have to set ? or the i386 distribution simply does not support larger raid, so I have to use x86_64 version, instead?

I am very happy with OpenVZ other than the fact that it doesn't support Windows, only Linux.I'd like to have VMWare Server 2.x installed, but it appears that OpenVZ changes the Kernel to, in my case, 2.6.18-194.3.1.el5.028stab069.6. The default kernel on my system is 2.6.18-194.3.1.el5.i386.If I change grub to load 2.6.18-194.3.1.el5.i386, VMWare will work but OpenVZ will not. If I change grub to load 2.6.18-194.3.1.el5.028stab069.6, OpenVZ will work, but VMWare will not.If I try to run /usr/bin/vmware-config.pl while in the 2.6.18-194.3.1.el5.028stab069.6 kernel, I get an error of:
None of the pre-built vmmon modules for VMware Server is suitable for your running kernel. Do you want this program to try to build the vmmon module for your system (you need to have a C compiler installed on your system)?Using compiler "/usr/bin/gcc". Use environment variable CC to override.
What is the location of the directory of C header files that match your running kernel?[/usr/ src/ linux/ include]I'm so lost as what to do now..is there anyway I can compile both of the kernels together somehow?
Will Redhat support CentOS under any circumstances? I have heard at my employer that if you setup you system with CentOS and then on down the line you find you need RHEL support that you can purchase a license from Redhat and they will support your CentOS installation.Is that an official policy at Redhat? Unofficial? Or completely untrue?
View 2 Replies View RelatedFirst off, let me say: I'm a long time Linux hobbyist and recently installed Fedora 12. I've been looking (some say "lurking") around these forums for a bit after I loaded it up and let me say: Leigh, You're an amazing young man! Keep up the great work! I've a question: I've just put together a hobby computer: Pentuim 4, with 1 Gig of RAM and a Nvidia Geforce5700LE. When I install Fedora from a fresh install, everything works great: nice screen resolution, good graphics, etc. but no 3d or acceleration, so I'm very limited on my programs.
So I decided I need to upgrade my Nvidia driver. I followed Leigh's Nvidia setup guide after installing Fedora 12 (all four steps!) everything seemed to go fine, but when I reboot, I quickly see the Nvidia splash screen, but the screen then goes blank. Well, not really blank, I can see what appears to be a kind of cross-hatch pattern, plus I can see what should be my mouse cursor on screen (it also is a square shaped pattern). I suspect it may be at a screen resolution that my monitor doesn't support. Once there, the computer pretty much doesn't do anything else. Usually I can break into the x driver loading and go to the command prompt, but this latest time I can't even do that.
I tried to installed Centos5.4 version on Dell PC intel corei3 inspiron580s and succeeded but found some issues following below
1 Hardware issue for LAN driver ( Broadcomlink(TM)gigabit ethernet)

3. What is minimum configuration for centos 5.4 ?
Is there any way to setup the Centos Directory Server without an internet connection?? i tried using the command: yum install centos-ds
but this just tries to connect to the internet to to download the packages. Is there a site where i can find the package so that i can copy it to my server and install it or is there some other way to do this?
I'm trying to use the set application to configure Apache. I'm getting a "setup: command not found" error when I type in "setup" at the command line.
However when I try to install setup with yum, it tells me that setup is already installed.

Does this mean kmod-xfs is no longer needed in centos 5.4 x64?

View 2 Replies View RelatedI have read in the release notes that there is no SuSe Linux (SLES 10) support in Cent OS 5.x KVM or even for that matter in Xen.
Does that mean SUSE will not run at all or will there be nobody to support me? A complete YOYO scenario!
Does anyone have experience with running SuSe on CentOS KVM?
We are trying to set up a NIS server on a CentOS system. We need to have a NIS server which can provide NIS authentication to a couple of clients. We are practically new to all this stuff.
Just googled to find some ideas about installing ypserv and ypbind and portmapper. We did all that and also started them successfully. But now the clients are not able to join to the NIS domain . The error log states "YP_DOMAIN NOT BOUND".
I guess we have not entered the /etc/yp.conf, /etc/hosts files properly. Please let us know the detailed steps to setup a NIS server .
Also, please let us know what entries should go into the different /etc/<file_names>? What is meant by HOSTNAME in the /etc/hosts file?
Is there any other files which need to be changed? Are we missing any steps?
Also to add-on, while executing the ypinit command we faced the following error:
At this point, we have to construct a list of the hosts which will run NIS servers. localhost.localdomain is in the list of NIS server hosts. Please cont inue to add the names for the other hosts, one per line. When you are done with the list, type a <control D>. next host to add: localhost.localdomain next host to add:
The current list of NIS servers looks like this:
Is this correct? [y/n: y] y
Error running Makefile.
So as the title says, I am looking for your experiences in this issue, because CentOs and RHEL are very, VERY similar, it is basically the same, so I was wondering, if I can get official support from Autodesk if I'll use their software on CentOs instead on RHEL.
