Re: Unable to boot after changing motherboard

Yeah, it's getting more like Windows in this respect. However, the issues I've seen in such cases usually went further in the boot, to the point of things like unable to mount root.... If you boot from an install CD there is a rescue option. I believe that will do what the rescue option has always ...

Hi, So I had CentOS 7 installed on an SSD, recently I moved the SSD to another machine and it would not boot...after showing the motherboard's logo, it went to black screen with a cursor flashing at left top corner.

Re: No ecryptfs-util in CentOS 7?

Also I am wondering, since I have multiple hard drives in my machine, I was asked for the pass phrase for the SSD partition when I boot the system, but not for the storage partition(which is a RAID 1 of 2 hard drives). Not sure if they are encrypted as well...I did choose "encrypt" when I was insta...

Re: No ecryptfs-util in CentOS 7?

BIOS boot password BTW: Usually a BIOS password can easily be cleared or changed, either by using a master password or by removing the battery for a while. (But this has of course nothing to do with LUKS.) Yeah...security counter measurement should consider when the bad guys have access to the hard...

No.
How is this achieved?

Re: No ecryptfs-util in CentOS 7?

Yes and "file level encryption" means encrypting files individually which luks does not do. What luks does is encrypt the entire block device and any files that are stored on top of that block device. The files are encrypted because they are on an encrypted filesystem. Let's say my computer is some...

Re: No ecryptfs-util in CentOS 7?

after that data is written as normal. Where did you get this information? LUKS does encryption, see for example http://en.wikipedia.org/wiki/Linux_Unified_Key_Setup https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Security_Guide/sect-Security_Guide-LUKS_Disk_Encryption....

I do not think LUKS does the job. It is more like another layer of "boot password", after that data is written as normal. I need an encryption layer like ecryptfs.
