I would like to mount a Xen image, so I can access the files in the Xen guest.
On SLES it is done like this
# open device
xm block-attach 0 tap:aio:/vm/backend.img xvda w
# Discover the attached disk
fdisk -l /dev/xvda

I'm experimenting with CentOS DS and have a question.Is it possible to attach windows xp machines to a CentOS DS? If so, how?!I think I've skimmed most of the documentation out there. Did I miss something? Is this not what the DS was designed to do?

Attach a Fedora/RHEL/CentOS system to an Active Directory DomainBelow is a step by step outline of how to configure a Linux Samba fileserver to use an Active Directory domain for authentication and authorization in place of flat files. Note that this configuration has been replicated using Fedora 10, RHEL 5.3 and CentOS 5 since they all more or less share the same code base.me of the example server in this document is erver1.domain.forest.org, substitute correctly where appropriate. At the very least following packages must also be installed:
sambasamba-commonsamba-clientkrb5-workstationopenldap-clientsIt would be prudent to understand the underlying concepts of how Kerberos and Samba work prior to deploying this type of server. I find that SE-Linux will interfere with Samba services, particularly with winbind. I usually set SE-Linux to be in a permissive mode. It is possible to update the SE-Linux policies but that is outside the scope of this document, i.e you're on your own. In some cases I turned SE-Linux off since it was causing winbind to stop responding.
1. Set NTP to use the correct server for your Active Directory domain:shell> system-config-timeSet the primary NTP server to be your domain/forest NTP server2. Make backups of and edit the following system configuration files:a. shell> cp /etc/resolv.conf /etc/resolv.conf.bakb. shell> vi /etc/resolv.conf
nameserver dns_server1_ip_address
nameserver dns_server2_ip_address

I am trying to do 1Meg IO to one of the block devices but I can only get a maximum of 512K IO size. I can use the corresponding sg device to get 1Meg of IO. I was wondering if anyone knows why 1Meg IO to a block device is being broken down into 2 512K chunks? I have increased the /sys/block/sdg/queue/max_sectors_kb to 16384, but it has made no difference.

I have the requirement that if our website receives 20 or more requests within 60 seconds, to block the offending IP address for 5 minutes, then allow them access again. My only certain mechanism to do this is iptables. I wrote the following series of commands:

iptables -N DOSAttack
iptables -N RemoveBlock

I am limited in my testing, but the little I have been able to test seems to be having no effect. will the above commands have the desired effect.
I had installed the CENT OS 5.3 it is installed when i rebooted it gives me error continuously.
Buffer I/O Error on device sda, Logical Block 0
ata4.00 : exception Emask 0x0 SAct 0x0 action 0x0 frozen ......

why it has giving the error.i have Intel based hardware Core II Duo with 1 GB ram check with sata hard drive 120 GB.
I just downloaded an iso of the latest CentOS dist (5.3) and burned it to disk. I booted from the CD and received the following error:
Memory for crash kernel (0x0 to 0x0) not within permissible range
Illegal mode for this track or incompatible medium -- (asc=0x64, ascq-0x00)
The failed "read 10" packet command was:
Buffer I/O error on device hdd, logical block 176935
(This error message repeats for another 9 or 10 times then it says the following)
Red Hat nash version 5.1.19.6 starting
Setting up new root fs
(Then there are some unmounts which are old /dev, /proc, /sys. At this point a series of steps begin).
Setting Clock
Starting udev
Loading default keymap (us)
Setting hostname local host.localdomain
Setting up logical volume management
Checking file systems
These are just some of the steps that appear after the above error is displayed, all of the steps that load have an ok status. After those are completed I get to a text prompt - localhost login: At this point my keyboard does not seem to respond, pressing enter or any of the other keys seems to have no effect. I noticed that during the load process I could toggle the light for caps and num lock, but at the login screen it does'nt work. So at this point I'm not sure if I'm having a technical issue or if its just another case of an user error.

View 1 Replies View RelatedIf I attach an NTFS drive to opensuse 11.3, will the OS see the drive and the files?
My goal:
I wanted to install OpenSuSE and add VMware Server 2.02 on top of it. I have a few hard drives that are NTFS. I need for my Windows virtual machines to see those hard drives. So in order for that to happen, the host OS would have to see the hard drives as well.
If I start a process with nohup:
nohup WHATEVER &
then how can I see it again? I mean how to attach my terminal to it again under Linux, e.g.: Ubuntu 11.04 - just like with the screen package.
If I want attach some images to e-mail or facebook, I can see just a names of files, usually numbers only. It is dificult to choose the right one, if I can not see prewiews. How can I do it?
View 5 Replies View RelatedI have a question about NFS and CentOS 6.0. Here is the environment: Server running VMware's esxi 3.5 (Fully patched) 10.1.1.50 Server running CentOS 5.5 with NFS. 10.1.1.51 With the systems in the above config everything is working fine. Install a new hard drive in the CentOS server and install CentOS 6.0. Use the same IP 10.1.1.51. Configure NFS, the VM server can't attach to the NFS share.
Here is the config of the NFS server:
Firewall Disabled
SELinux Disabled
NFS installed and running.
NFS-Utils installed.
Contents of /etc/exports
[Code]...
I have confirmed I can telnet to the ports listed. Any clue why the setup with CentOS 6.0 doesn't work? Is this a NFS4 vs. NFS3 thing? Is there a way to force CentOS to use NFS3? I am pretty sure the CentOS 5.5 server is using NFS4.

View 2 Replies View RelatedI have recently acquired a HP MSA 2040 san, which they say will work with Red Hat. But I'd much rather use Debian. It's attached to a Gen 9 DL360. I cannot get the OS to see the external drives. I hope it's just me mssing something.
I have told the DL360 to keep the external control in HBA mode, not RAID, not using the hosts RAID intelligence. I think I have set the MSA to offer a couple of disks as a virtual drive. I CAN see the drives in the BIOS boot menu for the DL360, though it doesn't show the virtual voilumes on the MSA, I cannot see the MSA virtual or physical drives once Debian is installed.
I have installed multipath-tools, and the SCSCi utilities.
But no luck seeing the drives.
