I recently decided to venture into the world of Linux/GNU by installing Ubuntu.
Before installing, I had a 190gb partition for windows 7 and 45gb of unallocated space. Through Wubi, I used the advanced partition editor to make a 6gb swap partition and a 22gb root partition for Ubuntu. All went well, but when I rebooted, I was unable to choose linux.
I installed Ubuntu by using Unetbootin to put the Ubuntu ISO on my USB drive. After installing, I disconnected the USB drive, and I was unable to choose the linux kernel option on the GRUB menu. When I do, my system just restarts and presents me with the GRUB menu again. However, windows 7 boots up perfectly.
I'm assuming that GRUB is somehow trying to boot the linux kernel from the USB. How do I change it to boot from the installation I made on my harddrive?
after update to kernel-2.6.18-164.el5 one of the 2 NIC's of my machine are only found at 1 of 4 reboots. Using the old one kernel-2.6.18-128.7.1.el5 all is fine. This are the to NIC's:
00:0a.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
00:0b.0 Ethernet controller: Intel Corporation 82557/8/9/0/1 Ethernet Pro 100 (rev 0c)
And the Intel one, makes the problems with the new kernel.
I compiled my kernel, compiled scsi support into kernel, used the new kernel and initrd, the boot failed.Then ,i unzip my initrd, found that sd_mod.ko can't be insert, i added it manual, and reboot OK.so, why! in the kernel configure , the sd_mod.ko is set to <M> , but why it can't be found in initrd?

I was just about to reboot the system when I realized that it runs VMWare Server Instance that will most likely fail to restart after kernel upgrade (I had a hard time fixing it after previous kernel update). Now I want to keep 2.6.18-128.4.1.el5 after reboot.I see that new kernel is scheduled for booting:
# cat /etc/grub.conf
default=0

I'm running CentOS 5.3 and would like to know what the "best" or "proper" method is to build a custom kernel using the generic kernel sources from kernel.org. Most of the references I've found talk about modifying the current CentOS kernel using the RPM way. I really want to have the latest kernel due to some important security issues that haven't been addressed in the current CentOS 5.3 kernel.
View 6 Replies View RelatedThe first server I installed installed fine. The second server, installed with the same config, went to "kernel panic not syncing no init found try passing init= option in kernel" error. I tried reinstalling but it keeps going to that error after install reboot. The storage is ISCSI connected via Intel Server Adapter, which allows it to boot from ISCSI. Not sure if that's the cause for the problem, but the first server is connected to the same ISCSI and installed just fine.
Is there a way that I can make sure ISCSI module installs during installation? Although I think it is installed since it's able to copy the files and setup /dev/sda. I just wana make sure that it installs during setup.
I built a home server (NAS/WWW/SSH/media server etc) and chose CentOS 5 as the OS (stability, easy of configuration).I was just about to start tuning the power consumption when I realised that the kernel CentOS uses is so "old" that it does not support the latest reduced power consumption enhancements that Linux has achieved in big strides in the recent past (we are probably still talking 6-12+ months ago e.g. tickless kernel)..
So my questions; 1) I know CentOS was maybe not meant for home servers (certainly its not its primary purpose), but if it is, any ideas of what kind of power consumption it takes (I know its relative) and if there are particular power consumptions that are worthwhile?
2) Do you recommend me compiling my own 2.6.21+ kernel from kernel.org or am I just likely to have compatibility issues (I really did not want to do that) or when is CentOS 5.4 supposed to have a newer 2.6.21+ version kernel?
Was it wrong of me in principle to choose CentOS for a home server when I am power conscious? (I don't have a low-power VIA processor either but a P4 so I am really just hoping to make do with software changes).
I am an old days RH release user(from 6.x) and just switching back from Debian/Ubuntu to CentOS on some servers, but I can not understand the kernel update strategy currently enabled in CentOS.There are two boxes, with almost identical installation, but recently there was an auto update of kernel on one box. This auto update also seems to issue an auto reboot on the machine, which is unacceptable on server machines.

1. I'd like to choose a small distribution, but one that is easy for me to deploy and manage (I'm new to Linux, but I am an IT professional). What shall I use?
2. I'd like to understand the implications of using Compact Flash. Will the OS need to write to disk? Can I configure my installation so that the CF card is read-only and provide a small writeable partition on my hard drive for any required IO? Should I not bother, and put it all on HD? (My motivation for using CF was to limit power-consumption/noise/heat).

View 2 Replies View RelatedIn the past (before UpStart was used in Ubuntu) I was able to configure multiple boot items in Grub menu to load the same kernel but into different runlevels. I had configured runlevel 3 (I went into /etc/rc3.d/ and removed the symlink to /etc/init.d/gdm) to be w/o GDM, so that if I had chosen it, my box would not boot into X. How can I achieve the same effect in Lucid?
View 2 Replies View RelatedI've used Ubuntu just a couple of times, and I've Never performed the Installation. I've been a Windows user mostly.But I'm ready for a change. I would like to Install Linux on my Desktop & Netbook Computer.Problem is, how to go about it.On the Desktop, I'm not the only person using it, and while I'm all & ready to try Ubuntu (Specially since XP Broke 3 days ago and the Format is impending) The rest of the people using the PC aren't. On the Netbook, right now I can't since I'm working on something, and I'm worried about compatibility issues between Platforms.So I did some research on how to get both Platforms up and running, and I found Wubi. Seemed like a perfect way to start!However, I downloaded the client, and when Downloading the rest of the Installation software, It just took way too long!On ETA it marked 4 hours at first (sure enough, it took little more than that) but then it gave me a new ETA of 8 HOURS!
Is there any other way to download it? Other than the 1.6 Mb Client file? & For the Desktop. Since I'm formating the HD anyway, What steps should I follow to install both OS on it?
what DVB-T USB tuner should I buy? I expect it to have full support including the remote control operation. Intended use is for Ubuntu with XBMC installed.

View 2 Replies View RelatedI was trying to install debian etch in my laptop, but it seems that the kernel 2.6.26 has a bug related to the ACPIC Timer and the HDD controler, so the installation in some part is freezed, so, I found that in the kernel 2.6.3xx the bugs are gone, it looks that i have to install unstable or testing, searching in the wiki is not enough clear for me what should I choose, so my question is:based in your experience, which is better to choose unstable or testing? I would use the laptop to code in LAMP, postgreSQL, J2EE and do some excercises related to networking services: SSH, DNS, iptables, etc

So I'm choosing between noname (Logilink ?) card with Sil3124 chip and HighPoint 1720 card. Functionality basically is the same for both cards or at least it is enough for my needs. I will run mdadm anyway. So the question is should I really pay 3 times more for HighPoint ? Is there any reason for that or Sil3124 will do the same ? What about compatibility ? As I know both cards are supported on thet kernel.
View 6 Replies View RelatedI want to set up a very simple version control system in my own computer, which only I will use. I want to use it mainly for latex files, not programming. I basically want to use it as a smart backup system and to keep track of past versions, but I don't need merging, patching, etc... My typical needs are the following:Work on a file many times and committ the changes every couple of days.Every now and then, try something new, and do it on a new branch. If it doesn't work, go back to the original one.
Take a look at a previous version (often a binary file, say a pdf or dvi file).I have used git so far, for no special reason, but I haven't been able to get comfortable with it, specially since it only handles text files efficiently (I think). My main issue is with point 3 above, I haven't found a way (maybe there's just no way) of pointing to a previous version of a file and opening it in an external program. Would CVS or SVN or any other version control system allow me to do this easily?
