What is root's login shell? It's the last field in the /etc/passwd entry.

it's /bin/bash
and /bin/bash exists with 755 permissions fyi.

Can you get back into your computer and chroot?

yep... sure can, actually that's how i'm getting this into from the /etc/password file and such.

thanks a ton for the quick replies so far

So, you can chroot /mnt/___ /bin/bash? That means bash isn't broken. Hmm...

ok, maybe some extra info may help shed some light on this. ok, i'm installing gentoo ON an athlon xp 2100+, 512 mb ram, blah blah. but i'm building it FOR an iopener (iopener has no cdrom). so i have built the system for a 486, and i switch the harddrive back and forth to boot from the cd.

---going to see if i can log in on the box it was built on-------

crap... i can log in on the athlon machine, but when i bring the hard drive to the iopener and boot and try to log in is where the problem lies. god i hope that doesn't effectively end the troubleshooting from ya'lls end.
:cry:

Is your PAM configuration OK?

Have you tried to erase root password in /etc/shadow ?

i erased and reset the root password, added a user, set his password, powered down, took the hard drive to the iopener, booted up and neither my user name or root can log in, it just accepts the password and logs me back out.

Do you have any security enabled in your kernel (grsecurity)?
Please post the result of "ldd /bin/login".
Do you have the same date/time on both boxes? (there is a security option for not allowing to logon after x active/inactive-time)

ok, security isn't enabled in the kernel,
the date and time for both boxes are pretty close to exact (within 30-45 secs). now the output for "ldd /bin/login" :

libpam_misc.so.0 => /lib/libpam_misc.so.0 (0x40019000)
libpam.so.0 => /lib/libpam.so.0 (0x4001c000)
libdl.so.2 => /lib/libdl.so.2 (0x40025000)
libc.so.6 => /lib/libc.so.6 (0x40029000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

Maybe the shell is dying with an illegal instruction trap...what are the CFLAGS and CXXFLAGS (if different) that you used to build this system?

Have you tried this?

http://www.kernel.org/pub/linux/libs/pam/Linux-PAM-html/pam-5.html

This will allow you into single user without a password. If that doesn't work, then I am out of ideas. I am assuming that is a PAM configuration issue. Also, I assume that your machines are on a network, you could setup ssh while it is in the AMD, and log into it remotely while back in the iopener..

yeah man, i've tried going to single user mode b4, here's the screwed up thing it does when i try that. ok, mine goes to a point that it says
"enter root password for maintainance"
"or hit Control-D For normal startup"

if i type in the root password it enters runlevel 3 and gives me a login prompt... doh
if i type control-d it enters init 3 and gives a login again... !!
i'm gonna boot up via the gentoo cd and try to check the log files, if there are certain log files other than the ones in /var/log/ could someone please point those out to me, cause i'm not aware of them.

thanks for yall's help...
