Weird Logging In problem
DOKNIK
All,
I am experiencing a weird problem on one of our E250's.When i try to login both remotely or locally i get the error messages below.I also tried login in using a tip session but still upon entering the root password it refuses connection throwing the errors below.
The system will not allow me to login because someone might have made some changes in the /etc/pam.conf and /var/adm/utmpx .I have tried booting from CDROM to use the installation CD to chmod the /etc/pam.conf .It allowed me to do that but it would not allow me to chmod to 644 on the other file ie /var/adm/utmpx.
After this change i tried login in again but still no joy
Any thoughts on this anyone.We are running Solaris 2.6, and the system has VXVM 3.0.4 installed on it.Any help would be greatly appreciated.Thanks

Probably you have your boot disk under VxVM control (encapsulated?)
That means that you have to:
- boot from cdrom
- try to mount the "rootvol" volume (i.e /dev/vx/dsk/rootdg/rootvol
or something similar)
- if this is not possible (that's probably a problem because
you don't have any VxVM modules loaded when you're booting
from cdrom) you have to try to mount the "original" devices
where your utmpx and pam.conf files are lying
Example for /etc/pam.conf
-> df -k .
-> lies on /
-> is mounted on /dev/vx/dsk/rootd/rootvol
-> has an "underlying" device /dev/dsk/c0t0d0s0 + /dev/dsk/c0t1d0s0 (RAID1)
-> mount /dev/dsk/c0t0d0s0 /mnt1
-> mount /dev/dsk/c0t1d0s0 /mnt2
-> edit or chmod /mnt1/etc/pam.conf and /mnt2/etc/pam.conf
-> umount /mnt1
-> umount /mnt2
-> reboot
If your /var/adm/utmpx file is located on another VxVM volume
you have to repeat the steps above.
The permissions of the files should look like this:
root@nfs1 > ls -l /etc/pam.conf /var/adm/utmpx
-rw-r--r-- 1 root sys 2431 Dec 29 03:59 /etc/pam.conf
-rw-r--r-- 1 root bin 4836 Feb 12 17:46 /var/adm/utmpx
If you know your former disk layout it could work.
Attention: I never tried it myself! It's just an idea...
Greetings and good luck,
Joe.
