cannot boot up my 32 bits centos 6.2

hi everybody,
i was not able to boot my 32 bit centos 6.2 on my machine. what i have done before is i was configuring my local ftp server so i add user
#groupadd ftpusers
#useradd user
#passwd user
#usermod -aG ftpusers -d /var/ftp/pub user
#chown root:ftpusers /var/ftp/pub
#chmod g+w /var/ftp/pub

just after some moment i saw alert something nautilus and when i reboot my system the error occurs before displaying users list and my mouse and keyboard doesn't work.

error = "could not update ICEauthority file /var/ftp/gdm/.ICEauthority"

so how can i troubleshoot that error and able to login i have important data. or is there any way to repair system without loosing my data

can anybody help me to find solutions i'll be greatful and accept any kinds of ideas and suggestions are welcome.

It appears like a permission problem with the file "/var/ftp/gdm/.ICEauthority". Just try loggin into single user mode and fix the issue with this file

thank you, blue_print.
for your quick reply i was able to login as single user mode but after that i don't know how to fix this problem.

What are the permissions of this file? You may need to modify them with something like (obviously you'll need to modify this code a bit):

Code:

 sudo chown $USER:$USER /home/$USER/.ICEauthority

sudo chmod 644 /home/username/.ICEauthority

or depending on permissions desired:

sudo chmod 600 $HOME/.ICEauthority

If that doesn't work you may need to reinstall the package with different options (as I've heard of this being the source of the error you're having.

thank you,
djsoundfx for your reply.

this is my /etc/passwd

Code:

khem:x:500:500:khem raj chamling rai:/home/khem:/bin/bash

so i was confused with this code

Code:

sudo chown $USER:$USER /home/$USER/.ICEauthority

sudo chmod 644 /home/username/.ICEauthority

or depending on permissions desired:

sudo chmod 600 $HOME/.ICEauthority

i have never use sudo command and do i have to put my username'khem'

Code:

$USER:$USER or

khem:kheem or

$khem:$khem

Code:

which premission file do i have to check. lastly if i reinstall centos again i have to loose all my data is there any repair mode in centos so i can save all of my data.
thank you.

Assuming user and group names are khem, khem (likely), then

Code:

# set ownerships

sudo chown khem:khem /home/khem/.ICEauthority



# perm mode may need to be 600 or 644; try 600

sudo chmod 644 /home/khem/.ICEauthority

Before you start, try

Code:

sudo ls -la /home/khem

to see what you've got already.

See the reply from chrism01 he setup specifically what you have to do.

So khem has root/administrative permissions? thats a bit odd that you're having this issue then.

thank you.

You do not have to lose all of your data and you DO NOT have to reinstall centos. You issue is with a single daemon/file it'd be a waste of effort to reinstall CentOS and that may not even fix your issue! Take the time to try to fix the permissions and see where that gets you. You can certainly repair your CentOS if with a liveCD or other method if you're unable to access the system or ever need to repair your bootloader but for the issue you're having you should be able to access the system and make changes without that.

Though I just read your original post again, so can you clarify if you're unable to access the system after this error appears?

thank you everybody,
for you quick reply and your help i really appreciate your support. lastly i have reinstall centos and loose my data.

THANK YOU.
