 Posted: Tue Sep 21, 2004 9:13 am Post subject: i missed up my users log in-- instant help needed |
 |
|
hi, i just managed to install gentoo aweek ago, and concidering this being the first time i ever interact with linux, i think i did a pretty good job. but now i think i did something really wrong
i was trying to create anew user called "arow"
and i typed exactly this
useradd -g users -G wheel -s /bin/bash -m arow
i didn't get anything wrong, now, i rebooted my system. the grup works fine, every check reads {ok}... and the nvidia and kde starts just fine. but then, the log in box is not the same as before, i dont have the user names with the pictures on the left side anymore.
and worst is that i can't log into the system neither as root or as any other group user... it keeps reading failed after i enter the username and password.
so, i have the system all intalled and working, but dont have any access to it. can you please help me... what should i do, to get my gentoo the way it was before i did the command of "useradd" ???? |

| If you press ctrl+alt+f1 you should switch to a console. Can you login there? |

https://forums.gentoo.org/viewtopic.php?t=197847&highlight=authentication+failure
offers a solution. Boot from your live cd, mount your root partition (/dev/hda3 probably)
mount /dev/hda3 /mnt/gentoo
then edit your password file:
nano -w /mnt/gentoo/etc/passwd
and remove the x ->
root:x:0:0:root:/root:/bin/bash
becomes:
root::0:0:root:/root:/bin/bash
Now you should be able to reboot (remove the livecd) and login again as root, leaving the password blank. Set a new password for the root with:
passwd
Then you should also be able to reset the passwd of the new user:
passwd arow |

| hey, i just tried the livecd booting, but i think maybe the file "/mnt/gentoo/etc/passwd" is read only or something, because i only get signs and marks when i enter it with nano |

Well I think it should work, and if the file is garbled it would explain why you can't login. Try to chroot into your mounted installation:
mount /dev/hda3 /mnt/gentoo
chroot /mnt/gentoo /bin/bash
env-update
* Caching service dependencies...
source /etc/profile
then:
mv /etc/passwd /etc/passwd.backup
emerge baselayout
and check if the file is reinstalled
cat /etc/passwd
and set your root passwd with:
passwd
next time you try to add the user use the command shown here:

well, i was trying to do what you are explaining and here are the problems i encountered.
when i try emerge baselayout it gives me this message
'portage' user or group missing.please update baselayout and merge portage user(250) and group(250) into your passwd and group files. non root compilation is disabled until then.
for the defaults, line 1 goes into passwd. and line 2 into group
portage:x:250:250:portage:/var/tmp/portage:/bin/false
portage::250:portage |

Ok sorry it didn't work yet  I've never had this problem, so I just guess the methods
We will try to use the passwd file from the livecd. I would think this one is the same as the one in the baselay out would be
| Code: |
mount /dev/hda3 /mnt/gentoo
mv /etc/passwd /mnt/gentoo/etc/passwd
chroot /mnt/gentoo /bin/bash
env-update
* Caching service dependencies...
source /etc/profile
|
now set your root passwd
as a reference: this should be what the default passwd file looks like:
| Code: |
[root@edder ~/tmp/rc-scripts-1.4.16/etc ]$ cat passwd
root:x:0:0:root:/root:/bin/bash
bin:x:1:1:bin:/bin:/bin/false

thanks alot man, i dont know which one helped but now its working just fine...
by the way it truned out that the password will get wrong every time i rebooted, and eventually i found out that there was some command i had to do that would make anew /etc/shadow file of the /etc/passwd and that fixed it
i appreciate the help man. |
