Software :: Unable To Access Hdd Direct Or From Live CD
Jun 8, 2010
I've got an Hitachi Deskstar 164GB IDE drive which I've somehow managed to upset while attempting to swap distros. I'm guessing its lost the MBR as I can't get a PC to see it except in the BIOS. The BIOS tells me that the primary master has 164GB, Cylinders 65535, Head 16, Precomp 0, Landing zone 65534 and Sector 255. (my understanding of that info is very limited). The PC won't boot direct from the hdd and a live Knoppix disc can't see it. Trying fdisk -l produces no list. (Naturally, I can't install another distro on it either).
I tried to install 10.04 but for the very first time since years I got stuck I have an integrated intel video card, 512MB of RAM, both the "try ubuntu without installation" and the "directly install ubuntu" run for a while showing the ubuntu loading splash screen and then everything freezes and the screen comes blank.
Im having a serious issue with booting ubuntu 10.04, the issue being it wont boot up at all, after working so well for so long (i suspect some recent dodgy system updates are responsible) so I decided to just reinstall ubuntu from scratch again but wanted to retrieve some important files from my root device. So I am running the live desktop and I can see my previous filesystems under places but cannot mount or open my original root device where the files I want to recover are located, I receive this error msg:"Unable to mount 77 GB Filesystem.
Installing from Live USB: Installing from USB on my desktop (used this method for laptop install) goes without a hitch. EXCEPT, I notice there is no support for my wireless card chipset (Atheros 7413, used /bin/lspci to find). I download the drivers for Linux, but I need Make to build the drivers...ok. I download the Make files from my laptop, make coffee, slap the makefiles onto a flash drive and run the configure file on my desktop version of SUSE. Whoops, need a c compiler (odd that openSUSE did not come with gcc? bit confused on that). If you can't tell by now, I've been using linux for less than a month so I am what you would call a noob? After the lack of c compiler, I drove to my office to snag some DVDs to download the DVD iso image, hoping it would have some form of c compiler/make packaged, since the description does say the DVD has more software (can't find any prebuilt versions of either...?)
Installing from DVD: This was my next step. I wrote the iso image to a DVD and proceeded to boot from DVD. The installer fails at the system analysis, saying it cannot "create a repository". writing the iso to a second DVD produces the same result. Googling has not yielded a solution. tl;dr can't use openSUSE on my desktop because my wireless chipset is not suported by SUSE. I need Make to build the drivers, but I need a c compiler to compile Make, and I need the internet to get both for my machine.
From my office and home, I can access a web service, no problem. However, from my server at the data center, I cannot. Could this be a DNS issue? I've tried with iptables enabled and disabled. selinux is disabled. This server has multiple network interfaces, one public and two private. The public has a WAN IP address (1.1.1.1), the private is 10.1.10.2 and the other private is connected via crossover cable to another server 192.168.100.1. I think route -n tells me the WAN interface is used to access the internet, as its gateway is my ISP's upstream gateway. CentOS 5.5.
can't access internet. The up and down icon appears by the network connection (upper right hand corner). When I review connection properties, I see that the computer has a valid address, subnet, gatway, dns, etc... But it still can't connect to the internet. I can't ping external addresses either. But I can access internal addresses (local router).
How can one have direct access to key strikes. Normally the key strikes that collected by the concerned programme and access to the same is not available to any other user programs. I am trying to write a program to simultaneously catch the key strikes. Obviously for this would require a low-level access to the keyboard. How can one do it ?
I have a single board computer previously running DOS. I recently made Linux running on it. Now that the system is running Linux, I have to translate the code that was supported by DOS. The code has segments that allow direct access of memory mapped registers through the macro _MK_FP and do read/write. I have read that where DOS allows this kind of direct memory access, Linux does not. Is there a way to do this in Linux?
Running Ubuntu Netbook remix on a Toshiba NB500-upgraded to 2 Gigabytes RAM. Very slow opening applications via the side icons. 8-12 seconds. Is that normal for this distro? - No 3D cube. Installed related compiz software, adjusted settings, ticked cubes etc. Not a peep. - No direct desktop access. Only via side icons. Just find it fiddly re: using desktop and changing background via side icons. Couple other items (MBB for one) but for another category.
Does a mailserver have to have direct access to WAN or can it be a LAN device with just one NIC ?
We have two WAN access points.
One is an adsl router joined to the switch and all seems fine for internet browsing.
The other is a wireless system with a linksys router joining by way of PPPoE and this appears to connect fine.
This PPPoE is direct to our ISP and where we need to downlod our mail to our pending mailserver.
When the linksys router is also joined to the switch all devices can use either the adsl or linksys to roam the net. 192.168.1.1 linksys & 192.168.1.10 is adsl.
When I join the linksys direct to the mailserver I will then need two NIC's. One for the Linksys and one for the LAN.
This is where the fun has started.
So.... Can I just have one NIC (connected to the switch) on the mailserver?
I am using a Dell Inspiron 14R laptop that came with Windows 7 Home Basic. The partitions of my hard disk before installing Fedora 15 were: Dell (OEM Partition) OS (C: ) (Primary Partition) RECOVERY (Primary Partition) New Volume (E: ) (Logical Drive)
I tried shrinking my C: drive (which has Windows) but couldn't do so hence performed the procedure on E: instead. I did this to create a 15GB unformatted space to install Fedora in. While installing Fedora, I chose the option "Use Free space" under Disk Partitioning Setup but the OS got installed in E: drive. Currently, I am able to use both Windows and Fedora under dual-boot but the problem I am facing is that when working with Windows, I am unable to see drive E: in Computer.
Windows Disk Manager is able to detect the partition and is showing it to be healthy (1st screenshot). Its name now is New Volume and neither am I able to change its path or letter (Error: incorrect parameters) nor am I able to check it using "chkdsk" (Error: cannot open volume for direct access/ GUI doesn't work as well) (2nd screenshot). On the other hand, I am able to access both the partitions in Fedora.
Another point to mention is that after finishing the installation of Fedora, when I started Windows, the Disk Manager as well as Dell DataSafe showed that the Windows Recovery drive had been formatted (maybe inappropriate terminology!) and was no longer retrievable. To rectify this problem, I restored my Windows to before Fedora was installed and I seem to have got the Recovery drive back (1st screenshot) (before doing this, it was nameless and empty).
Normally all I/O goes through the kernel so that it can schedule the operations and prevent processes from stepping on each other. A few special user processes are allowed to slide around the kernel, usually by being given direct access to I/O ports. X servers are the most common example of this isn't it ? give examples for any other processes that are allowed to slide around the kernel ?
my request is that i have to make all out bound internet connection should go from proxy server , not directly to firewall. Please specify a iptable rule for blocking direct internet access. my clients ip ranges from 192.168.2.20 to 192.168.2.47
I am in China, where some web sites(....., facebook, etc) are blocked. So I have to access these blocked site by VPN. But how can I access blocked sites by VPN and unblocked sites by my direct ADSL?
When I run OpenSUSE from the Live CD using normal settings, booting stops with a blank screen a moment after the kernel is loaded. When running it with ACPI disabled, it works, but direct rendering is disabled, even though it detects my video card (Mobility Radeon HD 5650) correctly Here's the Xorg.0.log file: my xorg log - [URL]
I cannot install Kubuntu (or Unbuntu) 10.4 on my husband's computer. I have spent 5 hours on this and cannot get anywhere. I am deeply frustrated. The iso I burned to CD is good (works on 2 other computers). His computer will not boot from USB, no matter what I do to the drive order in BIOS. After loading the blue screen with the Kubuntu logo on it (and the blue-white dots), the screen changes to black and shows the following text:
BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built-in shell (ash) (initrafs) Unable to find a medium containing a live file system.
He really needs to get rid of WinXP. Kubuntu is what I have on my computer (and love it!). Here is some info about his computer:
OS Name Microsoft Windows XP Home Edition Version 5.1.2600 Service Pack 3 Build 2600 OS Manufacturer Microsoft Corporation
ok so i ran into a problem, im using web min to access my server, and im setting up postfix and, dovecot first problem is i want to be able to access my email account from a web page, with log in, so my question is how can i do that?
I've been running a Samba server under RedHat 8 for five years without a hiccup. I want to cut over to a F10 box but cannot get shares accessible. smbclient attempts fail over NT password error. SELinux is disabled. Server is visible on the network. Users require no password access to shared data.
smb.conf follows:
# Samba config file created using SWAT # from UNKNOWN (>) # Date: 2009/06/12 14:15:15
I managed to configure my W890i phone to get access to internet through an ubuntu-based computer. It's very easy to use the phone to give internet access to the computer, but the opposite is quite more tricky. For that I've done the following
----On the phone---
-Set the USB network option to "through computer", so that the phone uses the computer's internet connection and not the opposite.
-Decide and set "Shared Network" parameters: user, pasword and workgroup.
-In "conectivity-> internet connection" set "allow local network" to "yes"
----On Ubuntu 10.04---
-Install samba, samba-client, smbfs, smbclient, firestarter and dhcp3-server
-Configure Samba (System-> Administration-> Shared folders): same workgroup as in the phone, add new user (the phone), passwd this new user. In my case the user was called "w890i" and the password given was the same.
-Once the phone is connected to the computer through USB (then select "phone mode"), a new connection appears in NetworkManager: usb0.The aim is to create a shared network that gives internet access to this device. Edit the IPv4 parameters of this new connection, set them to Manual and give an IP adress (192.168.0.1) and a subnet mask (255.255.255.0); the rest of the fields are left empty.Connect this network.
-Set firestarter to use dhcp3: sudo ln -sf /etc/init.d/dhcp3-server /etc/init.d/dhcpd
-Launch firestarter and follow the wizard. Set "allow internet shared connection", choose the device for the primary internet access, and then the device for the shared network (usb0). Then change the settings for firestarter: activate DHCP for local network, set IP to the one we gave before (192.168.0.1).
-Open dhcp3-server config file sudo gedit /etc/default/dhcp3-server And set INTERFACES="usb0"
-Set the policies of firestarter: in incoming connections, allow connections from the IP adress given to the phone (192.168.0.1). Then add rules for the ports that need to be open for this connection. I opened HTTP, HTTPS, SMB, SMTP, POP3, IMAP, IMAPS, DHCP for all the connections in the local network.
-Apply policies and start the firewall.
------------
After all this, the phone can access the internet through the computer. Two problems appeared:
1. I couldn't get access to https sites, like webmails. The phone gave a "communication error". But then I tried with Opera instead of the browser built in the phone's firmware, and I could finally get to https sites.
2. I couldn't retrieve mail, neither POP nor IMAP nor IMAPS. I thought it was a firmware problem again, and I tried out several mobile phone email clients written in java, but none of them worked.
So this is at the moment the problem. If I connect from the phone to the internet directly through 3G, the email clients work for all my accounts. I don't think it's a firewall problem, because the ports are opened for this connection
I need to backup my /home directory on the HDD. I broke the current ubuntu installation, so I can not just boot up the system without the live CD. Is there any way I can access my user data in /home? I need to back it up so I can reformat/reinstall.
Our family laptop (read lots of important pictures) is blue screening on boot. It gets part way through the windows boot (why I think it's still alive) and throws an error about unable to mount boot partition or something like that.I booted into Ubuntu live and cannot see the hard drive when I look in Nautilus. I do see the hard drive when I look in the disk utility. When I do sudo fdisk -l in terminal nothing comes up it just goes back to ubuntuubuntu:~
My laptop froze up this morning and required a forceful shutdown and since will not boot. it is a new drive in the machine and have to admit I had not tried my old Ubuntu partition since cloning the drive from my one I RMA'd to Western Digital. So I have downloaded 10.10 Desktop version and burnt to a DVD.
If I try and use Nautilus I can not view anything on the WinXP partition but I can access my NTFS Data drive and my old Ubuntu Studio partitions (which I can't boot although I see Grub options.)
If I go via Terminal I can get at least some access though. What Ubuntu is showing as the name looks suspiciously like a Windows serial number. Is it in fact what I registered my Windows with? Once I get into the Win partition I can view contents of C's root. Here I can view the boot.ini file (which all help on the internet I could find claimed had probably got corrupted) but it looks as it should. I can get into Program File and Documents and Settings so some of the drive seems to work (and I should be able to back up my settings, all Docs and data already live on another partition anyway.) But it will not access the WINDOWS folder. This means I can not try replacing stated missing files from WINDOWS/system32.
Is this because either part of WINDOWS has become corrupt? Or the Address Headers for it? Or is there something that locks off Ubuntu from accessing this that I need to change? Seems strange I get nothing at all listed for the WinXP drive on Nautilus but at least some access with Terminal. Is there a Check Disk type program within Ubuntu that can work on NTFS partitions? Last time I checked (fair few months ago now) there wasn't but here's hoping to progress.
I have a big problem with my ubuntu linux.. last night i was trying to execute a windows aplicacion (with wine).. suddenly the pc turned off.. later i turned it on but i couldnt enter to ubuntu... now i want to format my pc but i need to save some files on my flash drive.. because i cannot enter to ubuntu so i can save those files.. I used the Live CD, actually im using the live cd right now... the problem is that i dont know how to acces to my hard drive so i can save those files. every time I try to acces, this error appears...
Unable to Mount Location
DBus error org.gtk.Private.RemoteVolumeMonitor.Failed: An operation is already pending
I tried with right click>Mount... but this error appears..

Two days ago my Windows 7 just crashed and it doesn't work any more. Using a computer in a Internet point a downloaded Ubuntu 10.10 Live and now I'm running it in my computer. I would like to install Ubuntu definitely on my computer but before I would like to find all my old file from Windows 7. In Places/Computer has only the File System and nothing else. In System/Administration/Disk Utility I can see my 320 GB hard Disk (ATA Samsung HM3200II) but I can't do anything in that. I tried to use the Ubuntu 10.10 live in other computer and this work perfectly, but in this one no. What can I do to right now?
I was playing around with some files in Slackware and decided to do something stupid for the sake of experimentation. I wouldn't say I screwed something up because I did it intentionally to see what would happen (that's how you learn, right?), but I disabled my login tool. I need to access to the....
I do not have the machine personally but a friend of mine says her netbook with Linux detects the disk in the bios, but can not access it during the live usb. (but it worked previously). I have confirmed this with fdisk as fdisk detects the other devices as /dev/sdb and /dev/sdc, so it knows there is supposed to be a /dev/sda, but it is not there.
I've installed F10-live.iso onto a usb key but am having problems with the non-privileged user I created. When I login as kurt, I do not have access to my home directory on the hard drive. I tried [root@localhost home] #chmod kurt kurt (after cd-ing to the correct spot), but still cannot access my files there. I can do so as Live System User, but not as me.
