hello,
I am having a hard time with my mandrake 10.0.
since few days I can't login as a normal user. when I type the login and password I waite few minutes and I go back to the login window.
I can only login as root.
how can I fix this problem ?
thanks
tchoua

This should help.

I hope anyway.

Later

I tryed to change my user password but it doesn't solve the problem.
I am sure that the problem is not a password problem.
when I login the it start the graphic environement and then the screen goes black and I return on the login window.
It seems that it is more the user sesion that is broken.
I try to create a new user but I can't login with the new user.
my security is set to very few level.

try a different windowmanager or try a failsafe session

I can't log even in a text mode session I get the error : "login : no shell : permission denied"

login as root and check in which group th e user is in
also check the default shell ,usually it is bash
which distro are you using?

my user name is tchoua and my groups is tchoua and fileshare and I also cheked users (witch was not cheker and I thought that it was good to ckek it)
my bash is /bin/bash
and I am using a mandrake 10.0

Do a 'grep tchoua /etc/passwd' . It should look something like this:
tchoua:x:501:501:tchoua:/home/tchoua:/bin/bash

You can also try adding another user 'useradd test && passwd test' and try logging in as that.

yes my etc/password file has the correct line:
tchoua:x:501:501:chiausa francois:/home/tchoua:/bin/bash

I already tryed to create a new user but the problem is the same with that new user.

Check the permissions of /bin/bash : 'ls -la /bin/bash'
Also check /bin : 'ls -lad /bin'
bash chould be "-rwxr-xr-x" and /bin "drwxr-xr-x"
If not run 'chmod 755 /bin/bash ; chmod 755 /bin'

- Peder

permissions on /bin wasn't rwxr-xr-x so I change it for it.
chmod 755 /bin and now it has the rwxr-xr-x permissions.
this doesn't solve the problem.
do you have an other idea ?

Also check / the same way and chmod it 755 as well.

I'm guessing you ran some chmod command as root whan all of this happened and you managed
to screw up your filesystem rights.

I have more information on my error.
I did a strace su - tchoua -c /bin/bash and have a lots od error or file missing I'm not sure this is the message (it is very impressive so clean it up a bit) :
open("/etc/passwd", O_RDONLY) = -1 EACCES (Permission denied)
open("/etc/ld.so.cache", O_RDONLY) = -1 EACCES (Permission denied)
open("/lib/tls/i686/sse/mmx/libnss_nisplus.so.2", O_RDONLY) = -1 EACCES (Permission denied)
.... etc ....
stat64("/usr/lib/mmx", 0xbfffca20) = -1 EACCES (Permission denied)
open("/usr/lib/libnss_nisplus.so.2", O_RDONLY) = -1 EACCES (Permission denied)
stat64("/usr/lib", 0xbfffca20) = -1 EACCES (Permission denied)
open("/lib/libnss_nis.so.2", O_RDONLY) = -1 EACCES (Permission denied)

I don't know what to do and I event don't know what is the file libnss_nisplus.so.2 for ?
if this message means something to you give me an ansuwer.

Yupp, I really think you have screwed up your permissions. I bet an 'ls -lad / ' or 'ls -lad /etc' will show "rwx------" or similar.

Begin by 'chmod 755 / ' and see if things start to work. If not, the easiest way to get everything right is probably to reinstall MDK.
If that's not possible you could try
This could have some security implications if you have a multi user system (other users will be able to read log files
and stuff they normaly wouldn't).

libnss_nisplus is used if you login against NIS+ (Suns Directory Service, similar to Active Directory, LDAP or NDS).
It's a default in /etc/nsswitch.conf
