My centos 5.6 firewall server shares its Internet connection with my windows machine behind it. After the required settings, the windows machine can ping valid ip addresses but it cannot browse valid url (despite the fact that DNS is set for it).
View 14 RepliesAttempting to move from Xen to VMware, have dd old xen disk to image file and loaded in vmware. The disk is visible when running from a knoppix rescue disk however it can only be mounted as /dev/sda
On the Xen vm fdisk -l shows /dev/sda as:
Disk /dev/sda1 doesn't contain a valid partition table
This also reflects in the DD image. I'm assuming this is because it was part of a volume group ?? on the Xen Server. As it is mounted as /dev/sda on the knoppix rescue cd I can't run grub or seem to mount it as /dev/sda1 after recreating the partition in fdisk. How can I reinstall grub on this and get it to boot ?

I was trying to set up a partition on my netbook's hard drive, and foolishly forgot to backup my home folder. Now, Ubuntu (10.04, btw) won't boot. It allows me to get into the manual recovery shell, though. Now, I'm perfectly willing to reformat, but first I'm hoping I can recover the files from my home folder without having to take my netbook to the ridiculously overpriced computer repair centers in my area.
I have an external hard drive, but when it's plugged in during the recovery shell, it won't register as being a valid directory. I know the commands to copy or move a directory, but without my external reading as a valid directory to move my home folder to, I'm kinda stuck. Is there any other way to recover the contents of my home folder without having to go to a computer repair place? Neither of the ones in my area know much about linux at all, and I really don't want to have to pay $80+ to have someone else recover my home folder.

I am reading about jiffies in linux kernel. In one of the related example in the book Linux Device Driver, the author use
head -8 /proc/currentime
to print out some time information.
However this file is not present in my linux installation (kernel: 2.6.32-131.6.1.el6.x86_64). Why is it the case? Is it because the file path is no longer valid, or it is a distribution feature thing? It is not present in OSX too. What would be an equivalent in OSX?
I have an existing WinXP install on the main drive (/dev/sda) of a Dell laptop. I installed OpenSUSE 11.3 on the second (caddy tray) drive and didn't touch the existing windows partition during install.After install completed, I found there was no boot loader entry for WinXP during startup. Only SUSE-related stuff. I opened YaST boot loader and tried creating an entry of type "other" and device of "/dev/sda1" and set this as the default entry.The /boot/grub/menu.lst file now has an entry:Quote:

It's been years since I've set up a Linux machine and I am getting a "no valid devices were found on which to create new filesystems" during a Centos install on a Asus P5BV-C/4L motherboard.

I have ran into a permissions problem. It seems that any file I have created with Fedora I can browse to in Firefox. I cannot browse to files that I have downloaded from the internet or copied locally across our network. I changed file permissions to 755 and 777 for these files. I even thought that maybe it was the php file content that was causing the issue. So, I copied the file content from file 2 into file 1. File 1 was the file I could always browse to since I created it in Fedora. I could still browse to file 1 after it had file 2's content.
I look at the permissions and they appear the same for both files. I am not sure why I cannot open the other files. I downloaded phpMyAdmin. I cannot hit any of these files in a browser. I also copied some files from a a backup location we have internally. I cannot browse to any of these files either. I used chmod 777 filename. Even after doing that I could not hit any of the files. I moved the files into my document root directory ( /var/www/html ) and I still cannot browse to these files.
I cannot Browse Even Internet is Active. Connected using Mobile Broadband using Samsung Mobile USB MODEM. (Modem is recognized Successfully and Connection Shown as active!)

With the file browser, I can browse to file system/mnt/win and then the files and folders of the Windows share come up fine and I can open them. When I use the file browser to browse to network, the server hosting this share is listed. Then I browse to that server and it lists no shares (nothing at all). I can't go any further than the server. Is there a separate authentication necessary for the file browser to see this share from the network place?

I just switched from Ubuntu to Fedora (because of Unity) and everything works just fine. my printer. It is Canon LBP6000. A had problem installing it in Ubuntu as well, but finally I did manage it with this tutorial. Problem is that this tutorial does not work in Fedora, since update-rc.d is not valid in Fedora. I am not really a linux geek, just a long time user of Ubuntu. I can follow any tutorial given, but I havent found one for this printer & Fedora. Canon site says that this printer is tested on Fedora 12 and 13 64bit but I doubt it anyway. I am running Fedora 15 beta 64bit with Gnome 3.
