kernel 2.6.7.rc11
40 gig HD
boot : /dev/hdc1 file system ext2
swap: /dev/hdc2
root : /dev/hdc3 file system reiserfs

I've had the sytem off line for a couple of days and went to start it today. During the startup I'm told:

Hi,

I discovered that the fstab file was set back to defaults of ROOT BOOT and SWAP

I have been trying to get features added to the kernel....cups and had run a command < genkernel menuconfig all > Could this have rewritten the fstab fille... I thought I'v retstarted at least once siince do this but not a cold start.
Is this the difference it took to discover this?

I'm still faced with a system that will not accept my passwords for my root or user?

This may sound like a peculiar question but what is the Gentoo splashscreen like... This looks like a new splashscreen it just a block menu on a blank screen requesting my username and password with a large ICON within the menu..

I swtich between this another sytem and I'm not restarting the systems that much so I don't have much of a memory of what the Gentoo startup screen is or was?

Question is since it won't accept my password can I just go back to the liveCD and recreate the passwords... some how I don't think the LiveCd is going to allow me to fix these password issues

easy solution to recover the root passwords, and user passwords =>

chroot to your environmen from the live CD and type passwd will set the root password.

or without chrooting, editing the /etc/shadow file and remove the password hash (man shadow for more explaination)

EDIT : well the /mnt/gentoo/etc/shadow file exactly

recovered from the password problem

now I know why things looked strange with the splash screen... I've lost the boot into GNOME it's booting into (i think) what's called xterm. ... a very basic graphics gui.

I checked /home/user and it is in tact... so I need to figure out how to get the system to boot into GNOME and why any of this happened to begin with.

thanks for the support

Have you checked your /etc/rc.conf file? Make sure your XSession is set to Gnome and your displaymanager is set to gdm.

Hmm, as a general answer, have you recently made a etc-update ?

Well I got back my GNOME interface
had to re establish my user account

but I'm left without connection to the internet via my eth0. I'm not sure what's up with this. I have to research what will tell me its status; if it's even installed.

I wonder what knocked the hell out of everything and all my settings

thanks

back online with my gentoo system

#/sbin/dhcpcd eth0 was what reestablished connection... I'm not sure if that sets it permanently or not but at least I know now how to do it manually if it recurs
