I am having a hardware problem with my samba server. It is on an Tyan AMD motherboard, (Tyan S2469), and it appears the board has gone bad. Is it possible to transfer the drives onto my Tyan S2735 mother board without a complete reinstall? I really need to save the data on the system.

View 1 Replies View RelatedI had Windows XP Pro 32 bit and CentOS 5.4 installed on my Dell M6400 laptop and life was wonderful. Until I had to reinstall Windows. In the process, I reformated the C: partition of the drive where the Windows operating system was installed. I was careful NOT to reformat anything else. Now I cannot boot CentOS. The drive that has both the Windows and CentOS still shows the same partitions as were there before I reinstalled Windows, namely:
NTFS (C:) 171.82 GB
/boot 102 MB
(F:) 60.96 GB
is where my CentOS partition has all of my linux data and apps. I assume /boot should be the boot partition for CentOS I use Acronis OS Selector to show the partitions to boot. Now CentOS doesn't show as an option even if I go through the process of trying to detect a CentOS boot partition using OS Selector. I have researched this in the forums but have not found anything that was of help. There was a thread from someone who had trouble booting Ubuntu on a system with Windows Vista and CentOS but I did not see anything there that looked like it would help in my situation.

i installed CentOS 5.2 with two partition
ext3 / 14GB
swap 2GB
now is it possible 2 make a /var partition without reinstalling?
I am using CentOS 5.2 with GRUB booting a software RAID configuration. The first disk is md0 and is mirrored across sda1 and sdb1.I manually re-installed grub using grub-install and the machine will no longer boot off of the HD. The grub menu comes up, I can select my kernel the machine then jumps to loading the initrd and hangs.It will go no further. I have a live DVD that can boot from the HD. If I use that to first boot from the DVD, then specifiy the HD, it shows the same grub menu and then the machine boots fine w/o the initrd hang.I have tried re-installing grub but not been able to get the machine to work again w/o the DVD.

I've a Centos 5.1 server on S5000vsa Intel board with 6 bay HD in raid 1 mode (2 HD), and working fine until I've decide to make a yum update. Today the Centos is 5.4 but seems necesssary to upgrade the megasr driver for the raid function (i.e. , is not possible to contact the raid firmware trought Web Console 2). I've download the last megasr driver from Intel and I follow the instruction to upgrade the driver with s.o. installed, but when I start the server and choose via grub the new img boot file, the display show :
megasr.ko invalid module format -1 and stop. The linux version is the same in the machine (uname -a) and from the driver (2.6.18-164.9.1.el5). Another question : in Intel instruction spoken about megasr.o , but on img file I found a megasr.ko . I think instructions referre to old linux 2.4

What Linux command will return a Name to an IP?
I just installed CenOS 5 on my server and am in the process of installing some software to the machine.
I understand repositories and was able to get it all set up for installation with the yum command.
My problem is that when I attempt the install, it says i need root access to install.
I tried using sudo commands to switch to root access, but after entering the password, it says my username isn't allowed root and that my actions will be reported.
I am the admin for the system and have total control, I just don't know how to switch to root in the terminal.

View 9 Replies View RelatedI have router based on CentOS system with DHCP server. In one eth I have fiber converter attached in second one I have Cisco Catalyst switch connected. From the switch rest of ports are used to provide internet traffic to rest of network. I wanted to divide each segment of network (based on switch ports) that they don't see each other (it'll be good for me if someone will connect his wireless router to the network not to WAN by LAN port and start be a second DHCP server). So my network configuration:
CentOS:

Switch ports
1 - CentOS DHCP
2 - second server

Parts of networks I've assigned IPs 10.network_part.subnet_part.client_ip so I have addresses for clients: 10.1.1.2/8, 10.2.1.3/8, 10.3.0.4/8, etc ...

I have built a Centos 5.3 server for a friend of mine that is being used as a NAS server. The server has 4 1TB drives in a RAID 5 configuration and a dedicated non raid system drive for the OS. My friend isnt very Linux literate so I need this bow to be relatively simple. I have worked most of it out but have a question with regards to remote reboot.
I need to be able to shut this device down through the power switch without human intervention (at the moment when the power switch is pushed the server asks to confirm shutdown) the server wont have a Monitor connected so this isn't practical. Is it possible to use the power switch to do an clean, immediate shutdown?
The other option is shutdown through a web page is this something that has been done before? I know he can do it through terminal by issuing a shutdown now command but as I said this guy wants something simple. I don't really want to explain everytime he needs to shut the Server down how to do it if he can just do it via a website or even with the power button.
I'm running a Counter Strike 1.6 Game server on my centos 5 VPS.

View 5 Replies View RelatedI followed the instructions on this page ([URL]) in order to secure my sshd and prevent anyone form accessing the server directly as root. Therefore I changed the "PermitRootLogin yes" to "PermitRootLogin no" and restarted sshd. After that root access was denied directly but for some reason I am unable to switch to root from any of the normal user accounts with "su -" because I keep getting the "Incorrect password" errors. I am sure that the password is correct but for some, to me unclear, reasons I am unable to access the root account over SSH from a normal user account. I also noticed that after that I lost the ability to access the server as root over SFTP. why I am unable to generally use the root account after doing the named changes to sshd_config/ I am running CentOS 5.4 with the newest update.

VNC Viewer Free Edition 4.1.2 for X
Switching between two instances of VNC viewer in full-screen mode takes three key presses and two mouse clicks. How can the viewer be configured to pass a special key combination to the host operating system instead of the remote OS, so it's possible to switch between full-screen viewers in one key press?
e.g. With the default configuration, if I put the viewers in adjascent workspaces, then the sequence to switch is: F8 MouseClick Ctrl+Alt+Left F8 MouseClick If the key combination Ctrl+Alt+Left was passed to the host then it would be possible to switch workspaces (and therefore viewers) in one key press. When working on multiple remote machines, both physical and virtual, it's often necessary to switch between them frequently. I must switch over 100 times some days. Simplifying the key sequence would be both quicker and more intuitive.
I had something I think if very odd happen to one of my computers at work today, it appears to have spontaneously switched from having a static address set to getting its address by dhcp.this is a small office with a mix of mostly linux servers and desktops with a few stand alone windows computers, mostly notebooks. Most of the desktop computers get their address by dhcp, they all have NIS /NFS for remote mounted home directories (interchangeable desktops so anyone can log in at any desk). The particular desktop computer in question here has a shared printer on its parallel port, so has a static IP. Yesterday a UPS in the server rack died, after pulling it and plugging things back in and restarting the servers, it was easiest just to reboot all the desktops, everything came up ok including the desktop in question, and the printer did work.
Today I pulled the oversized UPS from this desktop to replace the dead one, and put a more appropriately sized one in its place, shut the servers down again, rebooted, etc,About an hour later someone tells me the printer is not working on the desktop, and after a lot of searching I find this desktop has the wrong IP address, I ran system-config-network and it showed the address was set to dhcp, I changed this back to the correct static IP and things seem to be working ok now.

I have a program that attaches to an interface. I can run two copies of the program on two systems (each running one instance), connect it to a switch, say 1.1.1.1 & 1.1.2.1. In this configuration two instances of the program can communicate and everything is fine.
Now, to reduce cost, it want to use only one system with two nics connected to the same switch, running two instances of the above program, each instance attached to two interfaces respectively on the system. I have the following settings:
