I have Windows 7 working on my laptop. I have 20GB space unpartitioned. I want to install a flavor of Linux like Fedora or Ubuntu in that space, but I have heard that keeping a dual OS configuration sometimes results in losing data stored on the hard disk. I've also heard that it may sometimes cause unrecoverable problem because when Linux is loaded on hard disk it will take over the boot loader from Windows.
Is this correct? Moreover, I have 6 partitions in Windows, but if I use a Live CD for Ubuntu or Fedora to boot, then it is not showing some partitions -- sometimes it shows only 4 or 5 partitions. What might be the problem, and how to resolve it without formatting the whole hard disk and repartitioning it?
I have a netbook running opensuse 11.2 I'm trying to make it run faster by disabling services, and I would like to kill off postfix as I don't ever use it (As far as i actually know) What harm could come from disabling postfix, if any?
I am pondering on what would be any implications in logging in via SSH as root?Surely SSH is safe or am I kidding myself and falling for the unwary ethic of logging into a remote Linux box as root?I discovered some open ports remotely on the linux box, and decided to login as root to edit a configuration file to shut off the ports, hence my questioning in whether logging in as root...another point, since SSH is 'supposedly secure', there should not be any implications or am I kidding myself!??? Would it be better to login as normal user then su from there?
Ok, to make things even more interesting, what if its a bog standard generic linux distribution with no suid programs etc, then what happens...take that out of the picture, and say, for editing a configuration file...hackers are not going to see that are they, otherwise by the sound of the answers, it is putting an impression that hackers can see the traffic the minute you login as root?! Otherwise why bother using SSH? I mean, surely, SSH was designed to replace telnet and thereby increase protection...as we all know back in the early 90's before the internet became publicly available, that there was indeed sysadmins dialing in to private networks or telnet'ting into a remote system as root....
I have a complete back-up file (on tgz) of a hardisk. I have already installed a SuSe Linux system on my computer. Can someone please provide a step by step procedure on how to install this back-up files?
I have a Windows laptop that isn't booting up anymore for some reason Safe Mode doesn't even work. Looking at what is printed out when it hangs, I did a search on google and it is some sort of HP laptop problem. Apparently the hard drive should still be OK, if only I can access it somehow. I was thinking maybe I could use one of those live Linux CDs to boot up. But I'm not too familiar with those. Would they be able to detect the laptop's DVD burner, and allow me to burn files off the NTFS partition to a blank DVD? I want to get my data off before I hand the laptop over to the IT department - who knows what they will do to it. So exactly which live Linux CD flavor should I use (my other working computer only has a CD burner)? And then would it be easy to burn a DVD after booting up the live Linux CD?
I want a log or live data that discloses the system calls an application makes. I have used strace but can't find a guide for it that is decent. I'm interested in knowing the calls made after user intervention like opening a menu and so on. If you run (strace application_name) it is static. What good is this? When does strace make this file? When is this log produced?
I am running Lubuntu 10 from a USB drive. Despite this, I believe this question pertains to any other variant as well. Running from the USB drive with a persistent directory, there is no boot options file that I can locate. As an example, for an installed version, the file /boot/grub/menu.lst can be changed to make boot options permanent.
Is there any way I can do something similar when booting from a USB live version? Specifically, I want to add "vga=799" to the options without typing it in at every launch.
Or is the only option for something like this actually installing to a USB drive instead of just running the live version?
I have accidentally changed the grub timeout to 0 seconds. My default boot is also set to windows xp so there is currently no possible way to boot into ubuntu. how to change the grub timeout without needing to startup into Ubuntu.
I've just upgraded to Ubuntu 9.10 and every several reboots my hardisk is checked for errors. It tooks about 1 hour or more. Is there a simple way to disable it and to perform these checks only when requested
recently I have been trying to create the perfect custom ubuntu .iso to write to a usb drive so i could carry around a live cd version of my current desktop operating system. I have 2 problems...
1: using various tools like Remastersys, Ubuntu Customization Kit, and Ubuntu's own LiveCDCustomization tutorial I have managed to install most of the packages that I want.... Truecrypt is not in the repos and i would very much like it on my custom live cd. while in chroot i tried using wget to download it then extract and install it, but i got a 404 error so it did not seem to be connecting to the place to download it. is there a workaround to getting truecrypt to install into my extracted squashfs? would it be possible to download the packages to my desktop then copy them over to my chroot squashfs to be installed?
2: I have not been able to customize the default appearance of the desktop environment like the background, icons,colors, window border, panels, applets, and so on.... Ubuntu's tutorial states that I need to edit .xmls in /etc/gconf but i do not understand how to edit those to get what I want. LiveCD creates a new user with default settings everytime it is started so its a matter of editing the files that control the settings of a new user.
i have this problem and i may need professional help; it appears smb4k made my /etc/sudoers file writable (according to log), hence, any sudo command will coerce this error:
Code: ubuntu@ubuntu~$ sudo any sudo: /etc/sudoers is mode 0640, should be 0440 sudo: no valid sudoers sources found, quitting i wanted to boot into recovery console and chmod 0440 /etc/sudoers, but it's a live system - it doesn't have a recovery mode. [URL].. How would i mount the live system from another liveCD?
I am new to linux, but need to do the following: 1.) Use a basic ubuntu 9.04 distro 2.) On boot run an existing .sh script
I would like to make a thumbdrive with a live cd version that will auto run to desktop and execute the .sh script. I am looking for pointers on accomplishing this. I have found ways to get the live cd to run on USB, but it still involves clicking the "run without changing your system link" and I cannot figure out how to run the script on start up.
I want to ask, its is possible to install ubuntu in a harddisk as a non persistent environment? i mean, i want my ubuntu is always clean everytime it is restart, like a live usb.
I recently reinstalled karmic, after upgrading lucid messed up my display.
I did not do a hard disk wipe, but just installed karmic in a new partition.
This presents a problem, which I think is due to permissions, that my other partitions does not mount automatically. Boot up shows a message that there's error.
After looking through the forums, most related issues i see are external devices (I may have missed it). Mine, however, is internal hard drive.
I have to manually mount it in desktop, by password authentication
Here's my fstab:
Code:
I would like to auto-mount it during boot, and perhaps get rid of the weird UUID.
I didn't leave much space for the / folder during installation of squeeze and now I can't seem to copy over old profile folder from a windows install of thunderbird. Any way to change the location of the profile folder?
I have my / partition on an SSD that I formatted in ext3 but I now realise that, in order to use TRIM, I need to be ext4. Can I use Partimage to make and image of the partition, format it (using GParted) and then restore the image? Basically, do Partimage files survive a filesystem change?
I have a problem to gain my hardisk size after deleting a large amount of files. i have root partition size with 196 GB. actual used size in that partition is about 70GB, with command df -h, the used size 139GB. I have no idea to find out where is the hidden files. this happend after I delete the large amount of files because the hardisk almost full. the file i have deleted is almost 60 GB size.
I currently have Zarafa and I am going to install MythWeb for MythTV.To solve the permission problem for installing amportal (FreePBX), I have to change Apache's user and group to Asterisk instead of this, which I've commented out:User ${APACHE_RUN_USER}Group ${APACHE_RUN_GROUP}Once FreePBX is installed completely, I checked to make sure FreePBX is working and it worked. I used the latest version of Asterisk from the SVN trunk, so I used ./install_amp --my-svn-is-correct.However, I want to use Zarafa AND FreePBX, I just don't like having to change the Apache User and Group to asterisk.Here is a couple of examples of instructions when installing FreePBX:Is there a workaround? I really want to change it back to what it was before while FreePBX can still access their own directories.
I did not know if this question has been asked, but I thought I'd ask here. I've added "zarafa" and "mythweb" to the tags list my thread.Update: I changed my apache configuration file back to www-data for User and Group and I do have /var/lib/asterisk/agi-bin and /var/www/asterisk (where FreePBX PHP pages are installed in /var/www/asterisk) owned by asterisk:asterisk. But I get this:
Code: Retrieve conf failed to copy file(s) from a module's agi-bin dir: copy(/var/lib/asterisk/agi-bin/directory): failed to open stream: Permission denied
i currently have both xubuntu 10.10 32-bit and windows 7 64-bit installed on my laptop which i use mostly for college work and basic programming (i'm still learning to program).i have a 150gb partition with win7 installed, a 20gb partition with xubuntu installed and a 15gb partition with my linux home folder on, the rest of the space is unused because i thought i may need it for something else in the future.the home folder partition is formatted to etc4, i now have a need to access this data from win7 for college work, i know that windows doesn't support mounting of etc file systems so i have hit a problem.
i thought about changing the type of partition from a ect4 to fat32 but will this delete my data? or ,are there any third party software packages for windows that will allow me to mount ect4?
I own an HP Envy 14 [url]. Letting Ubuntu (or any Linux) attempt to boot into a Live CD without changing any parameters results in a black screen, but with everything else working (for Ubuntu, that means the login sound is played). I've discovered that putting nomodeset in the kernel line will allow me to get so far as a command line, but I can't startx from here (I get "Screen(s) found, but none have a usable configuration."). I think my issues have something to do with the dual/switchable graphics in my laptop.
I have a windows install that is totally hosed, bluescreens, etc. I want to try to force mount it from Ubuntu to get whatever data I can, but it won't allow me to mount. It keeps telling me to run chkdsk /f and reboot twice. But that's not possible. I was wondering if there are any ntfs tools for Ubuntu or any data recovery tools I can use to get what I can from this drive.
Yesterday, my windows xp died and I can not do anything with that, but I would like to rescue my important files from hdd before format. I open ubuntu trial version from cd but i can not access my hdd. I find my hdd in system->administration->disk utility but I can not go anywhere from there.
When I solve this problem I would like to try ubuntu as my os but i am worried that some programs may not work on it . Like for example my bamboo tablet, fm2010, adobe ilustrator, autocad.
In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5
previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)
A few months ago I have setup a server with three hard disks. The partition mapping the disks as follows:
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x7ca36fee

Now I have the following problem the LVM file system don't mount properly.If I open the mount point I see only a few files of the LVM disk. If I want to unmount the disk I get the following error:
umount /data/ umount: /data/: not mounted
If I want to mount the volume I get the following error:
mount -a mount: /dev/mapper/gegevens-Data already mounted or /data busy
I have an harddisk which is old, since many years >10 years, and I recall I crashed few clusters using windows programs which were old and harddisk stuffs doing. So the pc lives with bad clusters, this pc lives very well since many years.Question, the pc has woody debian, which let us to install and exclude bad sectors during install. Bad clusters was an usual thing in the past, but today not anymore.Unfortunately debian squeeze installer coders had the good idea to remove the " bad cluster checking " before installing debian, during install (cdrom netinst).
I just downloaded OpenSuse 11.1 64 bit live cd from it's official site.I have live usb creater in my xp box , with the help of which I successfully created live USB for fedora 11 earlier. Now the problem is whenever I try to create live usb using Opensuse live ISO image after extracting all files to usb , it gets failed.The same thing is happening with OpenSolaris 11 live cd iso image. Does this mean that live usb creater I have, was only foe Fedora distros?
