Root cannot login

[trialex]

Hello everyone.
My root on my slackware cannot loggin.
It gives me the access denied error.I am sure that password is correct.
I can loggin as regular user though.Then when I try to SU it gives me this error:
Cannot execute sh: No such file or directory.
So I go to the passwd file and I see this entry under root.
root:0:0::/root:sh

Is that right?
What can I do to workaround the problem?
Thank you.

Not sure it would help, but have you tried resetting your root password?

I don't know exactly, but it can't start a shell.

My root entry in /etc/passwd is

root:x:0:0::/root:/bin/bash

so, it looks like it gives the full path of the shell.

The problem is your root shell points to "sh" which isn't even a fully qualified name. It should be something like "/bin/bash". You can try and do a "su root" (no dash) and try to get to a root shell and then modify the file, or you will have to boot into a single user mode and modify the file and then reboot. If any other user can write to the /etc/passwd (which is doubtful) you could do that too.

Also, if you can write to the "/" directory, try creating a soft link there like this "ln -s /bin/bash /sh". Then try to login as root again. I don't think this will work though unless you gave your own user ID special priviledges.
