I try to encrypt root file system on Opensuse 11.1 and I have found up to two possibilities.
1. [url]
2. [url]
In the first case, i have a Problem with entering password, for each partition on encrypted disk, i must enter my password.(For 3 partition 3 times)
And in the second version to get i nowhere.
Code:
I'm a long time user of Debian, but I'm having trouble with my partitioning process. Here is where I currently stand:
I am installing the latest Wheezy build. I am trying to install debian with an encrypted LVM that spans two hard disks.
My partitioning layout is as:
1. /home
2. /root
3. swap
4. /boot
I then added partitions 1, 2 and 3 to a physical volume group. I then took that physical volume group and added it to a logical volume. Then I encrypted the logical volume, leaving the /boot partition untouched. I was under the assumption that the only partition the system needed free to reach the loading of the LVM is the /boot partition, as it holds the files necessary for booting. But when I attempt to finalize the disk, it gives an error stating, "No root file system detected". That would be an issue as it is currently sitting inside the encrypted LV. Am I wrong in including the root partition in the encrypted LV?
What is the best way of having as little of my file system non-encrypted as possible while still allowing a proper boot?
Centos 5.3 includes Ext4 and improved support for encrypted file systems but it appears to be aimed at laptop/desktop systems, in that a password must be entered at boot time.
Is it possible to have a server with an encrypted root file system boot up without entering a password?
Mandos will do it...
http://wiki.fukt.bsnet.se/wiki/Mandos
...by serving up the password from another server...
http://packages.debian.org/squeeze/mandos
...to a client loaded into the initial RAM disk environment...
http://packages.debian.org/squeeze/mandos-client
...but it's not available on CentOS, and is only in Debian unstable.
Is there a similar (or any) solution for CentOS?
In particular, I'm envisaging encrypted virtual machines being served passwords from their virtual host.
Alternatively, the data that *really* needs to be protected could be encrypted while the system core remains unencrypted. But then the keys to decrypt the file system must be stored in the unencrypted portion, so this is not an effective method.
OpenSuSE 11.1 is by far the best SuSE version in a long time. It's generally up to competition or ahead of it. It's admirable, how thoughtful this system is set up, and how clean and fast it is compared to its predecessors. It ssems, that SuSE is fighting its way back to where they came from before the Novell "merger."
Having said that, it is even harder to understand, IMHO, why the installer doesn't support encrypted root partitions. Of course, there is a manual solution:
http://en.opensuse.org/Encrypted_Roo...ith_SUSE_HOWTO
However, this HOW-TO doesn't explain how to combine LUKS encryption with LVM on a RAID-1 system, as described for Slackware 12.2 here:

[url]
Is there a similar guide anywhere available for OpenSuSE 11.1?
If not: Would it be possible to do all the low-level setup work, like partitioning, setting up the logical volumes and encrypting everything, with Slackware, following the document above, and then install OpenSuSE 11.1 on that system? Would that work?
I am trying to replace just the kernel (no modules) for my default kernel on FC 11. I use the default .config file and just change a few things and then run the make command. After I replace the kernel and reboot the system the password comes up for the encrypted filesystem and it does not take my password for some reason. what I need to do to get this working?

I need a webserver (LAMP) running inside a virtual machine (#1) running as a service (#2) in headless mode (#3) with part or the whole file system encrypted (#4).The virtual machine will be started with no user intervention and provide access to a web application for users in the host machine. Points #1,#2 and #3 are checked and proved to be working fine with Sun VirtualBox, so my question is for #4:Can I encrypt all of the file system and still access the webserver (using a browser) or will GRUB ask me for a password?If encrypting all of the file system is not an option, can I encrypt only /home and /var/www? Will Apache/PHP be able to use files in /home or /var/www without asking for a password or mounting these partitions manually?
View 2 Replies View RelatedI've just started using ubuntu one. However, some of the files I store on there are sensitive so I encrypt them using seahorse. Right click, encrypt etc etc. My question is, is there a way to automatically get the encrypt process to delete the un-encrypted file when it makes the new encrypted copy?
View 6 Replies View RelatedI work for a company that makes portable devices running Linux and I was recently asked to make the underlying file system read-only for "security" purposes. Since the distribution is based on LinuxFromScratch, I know that very little writing happens at run time. So, even if the device runs on a usb flash device, I doubt that putting the root file system RO will be that beneficial. I am actually more concerned about a process actually breaking because it cannot open a file in RW mode than a process going rogue and filling the root file system with log files, etc. I'd really like to ear what kind of advantages disadvantages there really is with read-only file-systems.

View 1 Replies View RelatedI have worked in linux for a long time but never managed the system until I got my own server, which is running Fedora 14. I have a 3 TB Drive and apparently can only handle 2 TB. At least the Disk Analyzer is telling me that 2TB is 100% max capacity. Also viewing disk analyzer, I am only using 50GB of my 2TB but I am out of memory in the Root file system. If I run df -h, I get he following:

View 4 Replies View RelatedI have been using Ubuntu 9.10 Desktop version for around 1 month then i stoped using after installing windows 7, as I knew that there were the 10.04 version coming. So when it was released i went to torrent download the file and burned it on a cd. After that i insert the cd and use the wubi installer in there as i want to install them side by side. so after installing ubuntu i restarted the system and got into it. After a few minutes it appeared this error message "Not root file system is defined. Please correct this from the partitioning menu." So i was expecting it to be downloading problems. I went on to ubuntu website requested for a CD and it came today. So i inserted the cd did the same thing again.
View 9 Replies View RelatedIs it possible to run fsck on the root file system?
My Ubuntu 10.04 seems to be checking it's fs at boot...
It shows that the file system is in use and can get severely damaged!
Or the only possibility is to run it from a live CD?
My current installation setup has a separate partition for /, /boot, /home, /tmp, /usr, and /var. The problem I have is the root partition / is 98% full (4.3GB full). Cleaning temp files and log files won't help since they are on their own partition (and clean). I've removed all but two linux-images. Linux images seem to run at a size of roughly 105M. My root partition is 4.6GB. I can't seem to find any other options for cleaning up space on this partition. I have no idea what is taking up 4.6GB of space.
Disk Usage Analyzer has not been helpful since I have not been able to reconcile 4.6GB of memory with what it claims the total size of the remaining directories occupy. I've tried localepurge, gtkorphan, apt-get clean, apt-get autoclean, apt-get autoremove. I've removed all packages listed under Status -> Not Installed in the package manager. My root file system is still 98% full (4.3GB full).
Classic partition problem apparently. What do I do? the 11.04 wubi doesn't give a lot of installation options, so i just selected C drive, and gave it 10GB of space. instilled it, and when it goes to the desktop menu, that pop up appears saying No root file system is defined. Please correct this from the partitioning menu
In dual booting with XP. what do I do?
I'm trying to install 11.04 and get the error warning in the title. It says "Please correct this from the partitioning menu."How do I do that?I don't see any options for that.Puppy will already boot from that device and has grub installed.

I would like to know if there is a way to do an unattended check on the root file system on my servers, *and* send emails in case of errors.
I know you can schedule a root file system fsck during boot time - but the root file system will be mounted read-only - so if fsck finds any problems - it can't email away a warning, or write the result to a file - or can it?
Essentially I would like my servers to do a self-check of the root file system periodically - and to email me if it fails. I just can't think of a way to get it done.
I have a problem that is probably simple, but have not yet found the answer on any forums or by Googling. First my system specs:Tyan 2610 motherboard w/ 2 x PIII 9334 gig PC133 SDRAM
1 x 5 gig hd (system)4 x 500 gig hds w/ 3Ware 7500 controller set to RAID 5, (1.5 TB) mounted as /homeCentOS 5.3 running my smb and nfs mountsMy problem is that I have run out of space on my / (root) file system, (the 5 gig). Since I am planing to rebuild my file server with larger hard drives, (2 x's 60 gig SATA's set to RAID 1, 6 x's 1.5 TB at RAID 5), within the next 2 months, I would like to try to clean out any unneeded crap rather than adding a hard drive and expanding my root file system. I have done the following:
Removed old unused kernels
cleaned up /var/log/
cleaned up /tmp
