Ubuntu :: Unable To Access HDD After MBR Wiped / Enable This?
Nov 26, 2010
Wanted to restore laptop to Windows 7 and put Ubuntu on another machine.
The Laptop is an Acer and the Win 7 disks go into a propitiatory recovery screen. I have 3 choices reload Win 7 to new state, Load Win 7 and put everything in backup or Exit.
I have loaded the Ubuntu 10:10 Live and downloaded ms-sys. The problem is Ubuntu is unable to mount the HDD - not in fstab.
I've installed ubuntu 10.10 yesterday and i went to check something in my MS OS, im choosing "windows 7 loader XYZ"(XYZ reffers to something sda/....) in it comes back to the grub menu, any help please? im searching for hours for a solution and i can't find.
I'm running CentOS 5.5 with a hardware Areca controller (Raid 10). I initially installed a machine and rsynced the file system to a third machine; I'm then pulling in the file system to new machines and updating grub with a script to make it bootable.
I've done this before with other machines (no raid sets) but with these machines I'm running into errors code...
I have an external hard drive connected to my router. From Windows I can access it, but from Ubuntu I can see the hard drive, but when I try to access, I'm asked for a password. However my network does not have a password neither the hard drive. What must I do?
I recently installed Deluge 1.2.0 from the following PPA:[URL]I using this on two different Linux computers. One is running Linux Mint 8 and the other is running Ubuntu Netbook Remix 9.10. The first time on either computer when I enable WebUI in the Deluge GUI it works fine. However if I ever disable it in plugins section I am subsequently unable to re-enable it (doesn't appear in the side panel again). Rebooting or reinstalling Deluge seems to have no effect.Is this a bug or am I doing something wrong?
I'm pulling my hair out trying to figure out what is wrong with my Samba share. I have set up a directory /samba to serve up some movies, music, etc, on an Ubuntu 10.04 Server box. For now, I have given that directory 777 permissions, along with the subfolders:
Code: drwxrwxrwx 4 michal michal 4096 2010-06-22 18:02 Apps drwxrwxrwx 3 michal michal 4096 2010-06-22 19:02 Music drwxrwxrwx 3 michal michal 4096 2010-08-14 19:27 Pics drwxrwxrwx 5 michal michal 4096 2010-06-22 19:48 Video This is how my smb.conf file looks like for this particular share:
Code: [share1] comment = share1 browsable = yes path = /samba write list = michal Furthermore, I went ahead and mapped the Samba user to my Linux user account in /etc/samba/smbusers:
Code: michal = "michal" When I try to login from a Windows machine using michal as the username, I can see the folders, but I am unable to create new files on the share. Considering that the file system permissions are liberal on the share directory, I have no clue as to why I'm still getting denied write permission.
I recently got a computer donated to me for free from my Computer Science class, as the teacher couldn't figure out what the problem was that was preventing him from booting to the startup screen (all I could figure out was that the slot the memory card was in was bad, so I switched slots and got it working). The hard drive on the computer was wiped with a disk nuker called DBAN. Now I would like to install a Linux OS on the computer, but whatever disc or distro I try gives me similar "unable to read" errors. I would like to know if there's anything software-wise I need to do before attempting to replace any hardware. An example of the error I'm getting is as follows (using a mandriva livecd):
/etc/rc.d/rc.sysinit: line 1281: /var/log/dmesy: Read-only file system SQUASHFS error: sb_bread failed reading block 0xa6e58 SQUASHFS error: unable to read cache block [29b963ea:782] SQUASHFS error: unable to read directory block [29b963ea:782]
Anyone know what I need to do to get this fixed so that I can install a Linux distro?
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 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
Is TightVNC enable HTTP access inUbuntu 9.04?I use sudo apt-get install tightvncserver in the terminate and I can use VncViewer to view the ubuntu, but i cann't use webbrowser to view the utuntu.How can I access ubuntu in other pc with webbrowser?
Here is my problem: I had a 500GB HDD, with the fallowing partitions: C - 100GB - NTFS - Windows 7 D - 300GB - NTFS - (for staffs) H - 100GB - NTFS - unused
Yesterday I installed Ubuntu on tha last one (H), wishing to keep also the others two partitions. Now I can not access the first two, I don't see them any more. In my Disk Usage appears only the linux partition and one "Unallocated Space" of 400GB
Do you think that i have a chance to recover my data from the two partitions that I can't see them? code...
I had a Centos install that corrupted the boot and would only boot to GRUB. After about a week of trying linux rescue and various measures I gave up and installed a fresh copy of Centos on /dev/hda which is a 40 GB drive. All my data was on /dev/sda which I did not overwrite and is a 1TB SATA drive. I added sda to the LVM of hda now and is recognized as part of Partition 2 - using the GUI Logical Volume Management. My problem is I can't seem to figure out how to retreive my data from the sda2 drive. This is what I've tried. code...
How can I enable passphrase along with the password for login via ssh ? In that whenever I login from server A to server B via ssh, it should ask me for a password and then passphrase to allow me access. OR Can we have multiple passwords to login via ssh ?My basic need is to have 2 levels of password.
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'm using unr (9.10) and flash player works fine for me, the admin, but not for the other user on the computer. when the other users goes to videos, he gets a message that flash player is not installed or javascript is turned off. i checked and javascript is on.
I am setting up a computing cluster in my lab, as below. all the "eth0" IP addresses are static (for cluster communication) and the "eth1" of the front node is the only one connected to the internet through lab's DHCP server (which is connected to a centralized computer center in the university). The thing I wish to do is to do some sort of IP masquerading to enable all the nodes to have internet access. I actually google around and read some books. The similar things I came across is setting rules in iptables but I did not manage to get any of them working. I am using Ubuntu Lucid 64-bit on all machine.
When I put a DVD in my DVD drive I cannot get Ubuntu to play it, not with VLC, Enna, Boxee or Movie Player, with movie player I get "An Error Occurred Could not open location; you might not have permission to open the file."
With VLC I get some very slow jerky playback that crashes when I go full screen.
Problem: Error: no such device: f50139a2-b475-4ef5-8217-051bd145a24e. grub rescue> _
I know it is saying that the harddrive that I installed ubuntu is missing.
Heres the story:
My friend's computer wouldnt let him boot to the CD to install Ubuntu on his computer.
So I put his harddrive into my computer as my 3'rd Harddrive and booted the CD on my Machiene and installed Ubuntu to his harddrive.
We got ubuntu to work just fine, and then I removed his harddrive from my computer... big mistake. I no longer have the harddrive that we installed ubuntu to so I cannot use any programs or anything.
What I want to do is get my Windows 7 working again. Right now I cannot do ANYTHING.
So, I've been using Ubuntu (currently 10.04 lucid) for a while now and have added several repositories to my software sources before with never a problem, but now when I try to add a new repository the 'add source' button won't highlight and I am unable to add the repository. Does anyone have any idea why this might be because it is severely irritating me right now and I really don't want to have to completely reinstall Ubuntu to fix this.
I ran Windows on this computer but it decided it wanted to die on me yesterday, so right now I'm using a Ubuntu Live CD. I wanted to save my files before I install Ubuntu on this harddrive, but when I click on 'Computer', I can't see my harddrive. However, if I go to Disk Utility I am able to see the drive: Unknown (500GB) and Unknown (490GB). I cannot access any of the partitions, so I tried to mount them. When I do that, I get the message code...
The same goes with /sda1/ which kind of sucks. I also tried with /sda/ but it didn't work either. I should probably also mention that when I try to run the Ubuntu installer it shows my harddrive, but no partitions.
i'm currently running Ubuntu 11.04.Heres my problem. Everytime i try to run Compiz and apply some of the fantastic effects none of them seem to work. So this tells me that something is either wrong with my graphics driver (because upon a clean install of Ubuntu it says i don't have a graphics card that can supoort Unity) or i've just simply missed a step in adding one.I've checked Nvidia X server only to get the message "You do not appear to be using the NVIDIA X driver Please edit your x configuration file (just run `nvidia-xconfig as root)" I would love to run it in root if (and don't laugh) i only knew how :
From the many commands i've found online i've tired to either get to or find xorg.conf and if i'm mistaken doesn't exist for some reason. In a nutshell. I can't enable 3d acceleration, i can't find xorg.conf.I currently have 325m Nvidia card on my laptop, if it helps : I can give a ton of other information in necessary.
How do you enable a login screen? When I turn on my computer I only get command line. When I log into root I can start my KDE desktop using startx. But if I log into any other user I get the following errorX: usser not authorized to run the X server, aborting.giving up.xinit: No such file or directory (errno 2): unable to connect to X serverxinit: No such process (errno 3): Server error.
Is there a way to enable a web interface to access openssh-server on my vps incase i'm on a network that does not permit outbound port tcp 22 or any other port of my choosing?

Ubuntu desktop 9.04 Whenever I try to copy files to any machine on the network, the transfer stops and I no longer have access to the network or the internet. This happens whether I'm doing scp, copy with the gui, when copying to windows machines, and when uploading database files with phpmyadmin. I have been able to successfully transfer large amounts of data outside of the network via ftp, but not to any on the network. I've discovered that I can re-enable network access by restarting NetworkManager.
