Fedora Installation :: Evaluate The Checksum - Burned A CD With The Disc1.iso

Apr 1, 2010

I've downloaded the


files. I then downloaded "Fedora-12-x86_64-CHECKSUM" and ran sha1sum.exe on my iso files and compared the results. They were wrong for all 5 iso files. Figuring there was a problem with the way I was trying to evaluate the checksum I burned a CD with the disc1.iso. I received a "INSERT A BOOT DISK" error from my machine. I then tried downloading the disc1.iso again and ran checksum on my newly downloaded file and get the same checksum on both the old and new disc1.iso files.

When I run:

I get the response:

It seems to me the checksum value should be:

What am I doing wrong? I've installed many different distros in the past and am pretty sure I burned the iso file not just copied it to the CD.

Fedora Installation :: 10 Install - Burned Dvds Would Not Boot

Jan 30, 2009

I'm trying to install fedora 10 via dvd without a lot of success. i'm doing this on an old hp 8765c computer. it has a sansung sd-612 dvd-rom player. the dvd's i burned would not boot. so, i checked the dvd. sha1sum. check verify dvd when burned. check boot on system where the dvd burned. check dvd verify when bootedc check ok, lets check the dvd player. From i can see on the web, this player had issues about not playing dvds. some relate to driver issue when upgrading me to xp. and, some refer to updating firmware. lots of post about the dvd player not playing dvds. None with a succinct solution.

Well, if anyone has a solution for updating the firmware for a samsung sd-623 dvd player, it would be helpful. For now, installing from the internal dvd player isn't going to work for hardware reasons. Plan B lets try installing from the dvd using a network attached dvd server. sing the net install cd. use linux askmethod, use url to point to the dvd. the image in retreived, select all the defautl options, format the drive, does the package selection, does the package dependencies, but errors on the retriving packages. puts up the download retry message. then show message about not being able to retreive the authcong-gkt... rpm. just let the net install go. i get to the nic configuration, it errors out. probably network manager issue about trying to set a static ip address.........

Fedora Installation :: ISO Image Burned On CD - Dell 300SC Server

Jul 20, 2010

I have a Dell PowerEdge 300 SC that won't boot to the Fedora ISO image burned to the CD. I unpacked the .iso and the CD has the boot, isolinux and LiveOS folders visible. In the BIOS, I put the CD driver ahead of the hard drive in the boot sequence. It just doesn't see it. Is my hardware simply obsolete?

Fedora Installation :: Where To Get The Md5 Checksum To Verify If The Downloaded Iso Correct

Sep 13, 2009

I just downloaded the "Fedora-11-i686-Live-KDE.iso" and "Fedora-11-i686-Live.iso". I want to check if the downloaded files correct or not. I can use a tool to get the md5 sum of the downloaded files. But I want to compare them with the original ones.

Fedora Installation :: Torrent Downloads Repeatedly Fail Checksum?

Nov 27, 2009

I'm trying to upgrade to F11, and I'm having trouble. I attempted to download the x86_64 DVD .iso image by bit torrent, and it seemed okay, but when I started the installation the DVD failed the initial integrity check. I tried a second time with another DVD and got the same result.I tried running md5sum on the .iso image, but the response did not match what was in the CHECKSUM file that came with the .iso image -- should it? I tried downloading a live DVD image for comparison and found the same result - the response to the md5sum command did not match what was listed in the CHECKSUM file.Should these checksums match, or am I comparing apples and oranges? I thought the bit torrent client was supposed to check the files, but I'm not sure about that.

Ubuntu Installation :: Inspect And Evaluate The Mbr On A Disk?

Aug 5, 2011

How can i inspect and evaluate the mbr on a disk in a computer?

I'm interested in how to do this in general.

I can use gparted to see the partitions on a disk, but i don't know how to use it, or any other tool, to see just what is in the mbr.

The particular situation i'm in is that i have two disks in my computer. One has ubuntu 10.10 on a single partition, and one has 11.04 on one of 4 partitions.

The 11.04 disk used to be bootable, but somehow i messed up the disk: longer story: i installed another os on another partition, and the other os redid the mbr and installed a different version of grub, and i tried to reinstall grub but ended up with a disk that wouldn't boot. So i put my old 10.10 disk back into the machine so that i could at least boot and look around on the 11.04 disk.

Now, there are probably ways that i could recover the 11.04, but i would like very much to be able to systematically analyze the 11.04 disk to determine its exact current state before modifying it.

Since the disk is not mounted it seems like this should be in reach: i want to be able to (a) capture the mbr from the 11.04 disk [into, say, a file on the 10.10 disk] (b) get an analysis of what the mbr would do (where it points to etc, and what is at where it points to) (c) get any high level information which can easily be determined from (a) and (b).

Fedora :: Evaluate The Ext3 File System Performance

Apr 13, 2010

I need evaluate the ext3 file system performance; i need define:

- services provided
- parameters and
- the performance with different parameter values; for example, changin the value of the "data" parameter (journal, ordered, writeback).

I do not know what services ext3 provides. Well, i know intuitively that it provides services to read, write and erase files. But, there are anything more?. Where can i find the API?. Is the ext3 file system POSIX compliant?

Ubuntu Installation :: Burned DVD Of Version 9 Not Recognized

Jul 11, 2010

I've been trying for days now to install Ubuntu on a Dell Dimension 5100 desktop. It's got a 2ghz processor, ATI graphics card and 512 ram. It has a DVD drive that it boots from. Here's the problem. I have Ubuntu 10 burned on a regular CD and I have Ubuntu 9.1 burned on a DVD. I can boot this Dell up using the CD. It goes through the regular install, gets to 23% then tells me that it can't recognize the CD/DVD device or the hard drive. I've re-seated cables, I know the hardware is all good, this is my media computer that Ive had attached to my TV now for a year. It was running fine 3 days ago before I got the great idea to convert it to Linux.

Now...once that fails I try to put in the burned DVD of version 9. Again the computer boots, I tell it to boot from the DVD...but this time the computer acts as if that drive doesn't even exist. It simply can't find the DVD drive anymore once I put a DVD into it. Is this a problem with the basic reading?? It'll read a CD but not a DVD. If I let it boot all the way to the live Ubuntu CD, the DVD drive is recognized just fine, reads DVDs, etc. Is there another solution, something I should be trying? I need this comp on Ubuntu. I've already converted all other systems in my house and this POS is the only abomination still using windows.

Ubuntu Installation :: Checking Md5sum Of A Burned CD?

Dec 26, 2010

I checked the md5sum of the iso using winMd5Sum utility, it is OK.

To check the CD, right clicked the md5sum file in it, send to winmd5sum, and then copied the corresponding hash from the ubuntuhashes page into the bottom text box, and compared. The message box says md5 sums are different. Now the question is, have I done it correctly, I mean, is this the way to check a burned CD, OR, is there another way to check md5sum of a burned CD?

Ubuntu Installation :: 10.04 Desktop Edition - Burned Disk Not Readable

Apr 30, 2010

So I downloaded the Ubuntu 10.04 Desktop Edition and burned it to a disk. Shut off my computer and restarted it, booting from the CD Drive. It couldn't find it. So I thought maybe there was an unrecorded write error so I burned it to a second disc. Well after burning it I noticed I can't even see the disc anymore. It doesn't seem to be recognized at all. That explains why it didn't boot from CD.

But what I want to know is why on earth is it basically going invisible and not working? I've never had a problem with burning discs, especially Ubuntu stuff... So why...? Well I just booted up the CD on a different computer and it seems to be working fine. So it appears that my computer simply has ceased to see bootable discs or maybe its just non-empty discs.

Ubuntu Installation :: Openoffice / Firefox Fail Their Checksum

Oct 28, 2010

Using a 10.04 LTS installation disc, fresh are my install Firefox, multiple software, and the software updater thing did not work. Figured maybe I messed something up. I installed 10.04 LTS about 6 times from scratch, no other OS on the system. They all had issues loading software, I click on whatever it goes to launch and nothing ever comes up. I started doing updates through the command prompt using

sudo apt-get update
sudo apt-get upgrade

Then multiple packages broke. Tried sudo apt-get -f install but I keep getting an error that openoffice and firefox fail their checksum. Click on upgrade by 10.10 version gives me the screen that says are you sure, with all the information for the distro and then brings up a window that says download 2 out of 2 and it also crashes. So I figured alright, maybe the CD version I have is messed up. I downloaded the 10.10 iso image and burned it three times. Two of my live cds take me boot me to the purple ubuntu starting screen but nothing is displayed except for a little icon with a keyboard and the disabled person at the bottom. Then my computer reboots it does that continuously.

Ubuntu Installation :: 11.04 LiveCD - EDID Checksum Invalid

Jul 17, 2011

I burned a new disk with ubuntu 11.04 image and I managed to boot the live cd using my external monitor, I've installed and went into my monitor settings, it displays my external monitor as unknown and doesn't even detect my laptop screen. Changing the driver being used in my xorg.conf to vesa allows me to boot properly and ubuntu uses my laptop screen (yet it still detects it as an unknown monitor). Installing any nvidia driver and using it breaks my system. Heres an image of the laptop when using the nvidia driver (btw I can still hear the ubuntu sound that plays when its reached the logon prompt).

Fedora :: Find Checksum Code F11/12 64bit?

Feb 7, 2010

I have downloaded both fedora 11 64bit DVD iso and fedora 12 64 bit live cd,but the install failed on a brand new AMD Athlon II X4. The f11 was polite and said there were errors in the media, but f12 displayed an illegible line of text and stopped. On prior installs there was a obvious checksum value to verify that the download was good So far I have been unable to find one. I'd like to verify that the download is good before I buy more crappy cd's that don't work.

OpenSUSE Hardware :: Installation Ati 64 Bit Driver Failed - Checksum Incorrect?

Feb 14, 2010

when adding the www2.ati.com/suse/11.2 repo to yast and installing the fglrxg01 I get this errormessage: Fehler: INVALIDaket ati-fglrxG01-kmp-desktop-8.593_2.6.31.5_0.1-21.1 wurde anscheinend w�hrend des Transfers besch�digt. Wollen Sie es erneut abrufen? checksum incorrect)

Suse asks me to install it anyway but then decides to not let me install it, only leaves skip, cancel and retry. when doing skip, suse also managed to fcuk up Grub and removes all the entries for suse. Installing the driver doing like ATI Proprietary Driver Install Guide | openSuSE 11.2 vanilla - openSUSE Forums

fails miserably too. the free radeon driver on my FirePro V7750 on the Dell 6400 still has artefact all over screen, I hardly can type., this linux installing is still quite frustrating. or should I try Linux maybe in a year again?

Ubuntu Installation :: Via 8327 Raid 0 - ERROR: Via: Invalid Checksum On /dev/sdb

Aug 12, 2011

I am trying to install Unbuntu 11.04 on a Via raid 0. I have windows already setup and it boots fine, but Ubuntu does not see the raid set. Running dmraid -ay (or any valid switch with dmraid) returns :

sudo dmraid -ay -v
ERROR: via: invalid checksum on /dev/sdb
ERROR: via: invalid checksum on /dev/sda
no raid disks

mainboard is Asus M2V, with 2x Hitachi 250Gb disks in raid 0 configuration set in BIOS. I have a 3rd hard disk on the onboard Marvell 88SE6121 sata controller but this is not seen at all by Ubuntu either. I was thinking of installing it here if Ubuntu does not work the RAID, but no go it would seem. I do remember installing an earlier version of ubuntu on this very same board using RAID 0 (2x 80Gb drives at that time) and the RAID was reconised and worked fine straight from live cd to full install.

General :: Evaluate Size Of Output Command?

Nov 18, 2010

I'm trying to do something like this:

cmd1=$(cat /var/log/messages | grep -e 'blocked for more than 120 seconds' | cut -c 55-62)
if $cmd1 != 0; then echo 'okay'; fi

however i'm messing up somewhere... bash attempts to evaluate the elements in cmd1. when I try to run this script it complains saying:


test1.sh: line 5: blocked: command not found

I am open to alternatives. My intent is to replace cat /var/log/messages with dmesg, so I can attempt to determine if a problematic application I use encounters a blocked state (unresponsive for more than 120 seconds).

Should I be using a different test condition? I tried something like:

# this declares cmd1 as an array
cmd1=($(cat /var/log/messages | grep -e 'blocked for more than 120 seconds' | cut -c 55-62))
#attempt to determine if number of elements in array is greater than zero
if ${#cmd1[@]} > 0; then echo okay; fi

But I get the same error... what am I doing wrong?

OpenSUSE Network :: Using Nessus To Evaluate Security Of Web Server?

I am using nessus to evaluate the security of a web server. I have started up the nessus daemon on the server, here's the netstat output:

It's listening on the default nessus port 9390. I am trying to connect to the nessus server instance using Open-VAS Client. I have generated the client and server certificates, I have pointed the client at the User Certificate File, the User Key File and I have a CA cert. I have created a user account on the nessus server. The problem is that when I try and log in from the Open-VAS client it keeps saying it can't connect. Is there anywhere I can check to see if it's being caught in a firewall, or where I can see if the connection is even making it to the server..
