 Posted: Wed Mar 05, 2003 6:48 pm Post subject: Problems logging in. |
 |
|
Ive just installed gentoo on my new Acer laptop. Everything worked fine, building bootstrap, stage1 + 2 + 3.
Ive added a new user with the superadduser script, but Im unable to do a login with that newly added user. Only root is able to login.
When typing in the username and passwd, it just jumps down to a new login, it does not show the command prompt. As usual.
I have checked /etc/passwd file to see if the user is using /bin/bash wich it does, also /var/log/auth.log shows nothing unusual.
Whats wrong   |

try adding a user the old fashioned way:
| Code: | useradd -c "<full name>" -d /home/<username> -k /etc/skel -m -s /bin/bash <username>
passwd <username>

I'm not sure if the superadduser script makes home directories or not, but you might want to check to make sure that your user has one. If not, you can simply make one manually.

If you think you've properly created the user, and can log in as root the first thing I would try is this; log in as root, then 'passwd whoever' to reset whoever's password. Next <ctrl>+<d> and try to log in as whoever. I know it sounds obvious (or perhaps stupid  ), but it has worked for me when I've been in the same situation. |

Does the problem happen if you login with a different user (not root)?

have you tried doing "chmod 777 /home/<username>"?
I myself did that and haven't had any login problems... sounds to me like the user doesn't have access to the dir. nevermind who owns it...
just a quick thought.

Yikes. That's not a good solution. Now everyone in the entire world has access to your home directory. Better to find the real cause of the problem instead of initiating a work around.

It may be useful is you were to post the output of:
| Code: | | ls -al /home/<user dir> |
Also post the offending user's entry from the passwd file.[/code]

yes, I know, that was the "quick fix"... but if it fixes the problem then at least it has to do with directory permissions
after that you could try reducing outside permissions...

I was wondering if you had tried more than one non-root user.

I have a similar login problem - I think it started after a recent emerge system.
I can log in directly at a console, but not over ssh. If I try ssh, the connection dies immediately after I enter the password.
Directly at a consoloe login (or if I su over ssh) I get
| Code: | /usr/bin/whoami: cannot find username for UID 1002
bash: [: =: unary operator expected |
I get the same message when I su over ssh and source /etc/profile.
This might be related - I have three interesting files in my /etc dir:
Any ideas?
[edit]I just created a new user (to test this issue) with: | Code: | | useradd -c "<full name>" -d /home/<homedir> -k /etc/skel -m -s /bin/bash <username> |
Same message. I can login at the computer, but my prompt is as follows: I have no name!@<host> <username> $[/edit] |

i found a little workaround thats works for me.
i use gdm to login into kde ( kdm crashes when a non-root user trys to login )
and for shell login i use tinylogin.
| Code: |
emerge tinylogin
mv /bin/login /bin/login.old
cp /bin/tinylogin /bin/login
|
may be this is "evil" but it works for me |

I still have the same issue!
A similar  login-related thread suggests the following:
| Code: | emerge sync
emerge devfsd cracklib pwdb pam shadow pam-login |
The machine with this issue is at work... I'll do this myself later... and post my results |

Double check the permissions on the passwd, shadow and group files under /etc. They should look like this:
| Code: |
$ ls -l /etc/passwd /etc/shadow /etc/group
-rw-r--r-- 1 root root 675 Jan 31 09:22 /etc/group
-rw-r--r-- 1 root root 1813 Apr 9 10:52 /etc/passwd
-rw------- 1 root root 1135 Apr 9 10:52 /etc/shadow
$
|
the next thing to check are the pam rules...
| Code: |
$ ls -ld /etc/pam.d
drwxr-xr-x 2 root root 4096 Jan 31 08:59 pam.d
$
|
AND the things in the directory
| Code: |
$ ls -la /etc/pam.d
total 100
drwxr-xr-x 2 root root 4096 Jan 31 08:59 .
drwxr-xr-x 59 root root 4096 Apr 18 10:20 ..
-rw-r--r-- 1 root root 227 Jan 31 08:59 chage
-rw-r--r-- 1 root root 227 Jan 31 08:59 chfn
-rw-r--r-- 1 root root 227 Jan 31 08:59 chsh
-rw-r--r-- 1 root root 232 Mar 17 14:28 cups
-rw-r--r-- 1 root root 380 Feb 10 09:28 gdm
-rw-r--r-- 1 root root 406 Feb 10 09:28 gdm-autologin
-rw-r--r-- 1 root root 288 Feb 10 09:28 gdmconfig
-rw-r--r-- 1 root root 227 Jan 31 08:59 groupadd
-rw-r--r-- 1 root root 431 Jan 31 08:59 login
-rw-r--r-- 1 root root 198 Jan 31 08:59 other
-rw-r--r-- 1 root root 214 Jan 31 08:59 passwd
-rw-r--r-- 1 root root 457 Jan 31 03:48 rexec
-rw-r--r-- 1 root root 580 Jan 31 03:48 rlogin
-rw-r--r-- 1 root root 445 Jan 31 03:48 rsh
-rw-r--r-- 1 root root 227 Jan 31 08:59 shadow
-rw-r--r-- 1 root root 294 Jan 31 09:22 sshd
-rw-r--r-- 1 root root 1247 Jan 31 08:59 su
-rw-r--r-- 1 root root 491 Jan 31 08:59 system-auth
-rw-r--r-- 1 root root 227 Jan 31 08:59 useradd
-rw-r--r-- 1 root root 380 Mar 22 10:16 xdm
-rw-r--r-- 1 root root 79 Oct 27 23:51 xscreensaver
-rw-r--r-- 1 root root 284 Mar 22 10:16 xserver
$
|
The permissions should be similar. What's in pam.d is dependent upon what you have emerged into your system.

Thanks dweigert, it was indeed my passwd permissions. I'm guessing I messed them up when I was screwing around with samba? Or maybe I was hacked... At any rate, I have a name now!!!

@dweigert - THANK YOU! That was my issue! The /etc/group and /etc/passwd files did not have read access set for group or other.
No I can log in as a normal user, both locally and through ssh, and my name shows up.
Thank you again Dan  |
