Pxe Debug

Hi, I'm pretty new to Linux.

I'm currently working on a project in my Linux Administration class, but have run into a bit of a bump.

I'm tasked with booting Linux (currently using CentOS 7) through the GRUB prompt. I've loaded the kernel, but I'm having an issue with the initrd.

I've tried both of these commands:
"linux /boot/initrd-plymouth.img"
"linux /boot/initramfs-3.10.0-123.el7.x86_64.img"

Neither of these commands have worked. It only returns the message "invalid magic number" for both of the commands. Any ideas on how I can fix this?

Thanks for any help in advance. It should help me understand Linux better!

Hi Guys & Girls

I'm planning to reuse my old hw for a home server based on debian.
I want to provide my lan with 4 to 5 services like router/dhcp, tftp, pxe/fw, nfs-server, media-server, clonzilla-server, squid-dansguardian and eventually later on a small mta/webmail, horde solution.

How would you set this up?

An all-in-one machine running natively on the hw or separate vms @ kvm?
I would also like to have a stable and good manageable backup architecture, like using a central clonezilla server instance to pick up everything from the other services.

Greetings and thanks a lot

Im looking for a distro for a web server (Apache).

Ive always used Ubuntu but I didnt think it was the best for the job so I looked around and found CentOS.

CentOS is great, really simple to use but I wanted the latest and greatest.

Im getting replies that CentOS is about stable and I cant put the latest so I see now that distro is not for me.

Im looking for a distro that is simple to setup to run a small website off of (no big traffic, if any) and with the latest possible to be installed. It will probably be Wordpress. What distros do you guys recommend that I can run cutting edge web server technology (talking Apache 2.4.12, MySQL 5.6.24, PHP 5.6.8, etc.) and upgrade as soon as a new version comes out.

I figured out there is a possibility that I can change the algorithm in the built-in cryptor, in the openSUSE install. The default algo loaded is AES and I want to change it to Twofish. I saw a post in gentoo's forums where it seems to be possible, although I don't know if I can do the graphic install after it nor how to procceed.

The command would be similar to:

Code:

cryptsetup -y --cipher twofish-cbc-essiv:sha512 --key-size 256 luksFormat /dev/sda3

What should I do? How to install the system afterwards? (with graphical install). Also, is there a way to check the encryption description after the system install?

I want to install openSUSE 12.3

Hello.

I have such links in a web site

/post.php?id=14
/cat.php?t=y&cid=6666

and i create an .htaccess file with that content inside.

Code:

Options +FollowSymLinks 
RewriteEngine On 
RewriteRule ^([^/]*)$ /post.php?id=$1 [L] 
RewriteRule ^([^/]*)/([^/]*)$ /cat.php?t=$1&cid=$2 [L]

but on refresh, apache returns 500 Internal server error.

I looked on logs and found that :
Quote:
AH00124: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.
Why that happens ? Mod_rewrite is enabled in httpd.conf.

Hi All,

Please help me. I'm following the book - ' DNS and BIND, 5th Ed By Paul Albitz, Cricket Liu '. This RNDC is driving me crazy. I spent all day trying to configure rndc. Tried every possible combination in config files, but I just cant control remote server. Tried many tutorials from google, nothing helped. LQ is my last hope.

So, my story goes like this...

MASTER BIND SERVER:
Host: toystory.movie.edu
IP: 10.249.249.3/24
OS: CentOS 7.1

SLAVE BIND SERVER:
Host: wormhole.movie.edu

OS: CentOS 6.6

MASTER SERVER (toystory) CONFIGURATION FILES:
Code:

[root@toystory ~]# cat /etc/rndc.conf

	secret "K9qBsQwusP6430cykS2AeA==";
};
options {
	default-key "toystory-key";
	default-server 127.0.0.1;
	default-port 953;
};

[root@toystory ~]# cat /etc/named.conf

	secret "7PvoY3oysQz8DyASiUTlNA==";
};
controls {
	inet 10.249.249.3 port 953
		allow { 10.249.249.2; } keys { "wormhole-key"; };
};

Code:

Hello

I am trying to log the Kernel level PPPd raw PPP messages (version 2.4.2) using Linux kernel 2.6.x to the /etc/syslog or /var/log/messages but the logging is not enabled for some reason.

I pass the kdebug 7 or kdebug 31 to the PPPd using /etc/ppp/options but the Kernel level debug logs are not shown in /proc/kmsg or using klogd or syslogd.

Can anyone please help me to fix this. What might be the problem?

Please reply..

Thanks,
Rakesh

the result comes fine but the log is not make in /var/log/queries.log file.
The named is running without chroot enviroment.
Please help me in solving this.

Hello.

I don't know if this forum is the correct one to ask about this problem. Feel free to move it to another forum.

I am running PelicanHPC, a Debian-live based clustering distro.
It sets up a DHCP server, and offer PXE boot to other machines in a network.
I have switch off the DHCP server in my router.

Problem is that when I boot from this computer through the network, it displays a message for a split of a second: Succeed download. I guess that it is downloading the NBP correctly. But then, it's just returning to BIOS and/or booting my OS normally.

The other computer is offering a non-EFI image, and this computer boots: UEFI: PXE IPv4. Maybe there is a mismatch, but I have no idea on how to fix this.

What can I do to boot it correctly?

If you need more information, just ask me about it.

Thank you

Wireless mouse and wireless keyboard is not working in Linux distro's.

Read the similar threads on this issue. Boot mode is set for UEFI and Legacy therefore not sure what to do to enable mouse and keyboard? The mouse and keyboard use the same 'receiver' and the receiver indicator is green when Linux distro is fully loaded. Have tried various distro's, Ubuntu, and Ubuntu based distro's using LIVE DVD method on all. Latest distro tried is Peach 14.04.1 TW.40 64 bit. Motherboard is a Gigabyte GA-990FXA-UD3, CPU AMD FX6300 3.5 Ghz six core.

Thanks for any assistance.
