I have changed some stuff in nsswitch.conf [possibly adding nis to the passed entry or something like that. nsswitch.conf did not have a man page]. I got back to work this morning and tried to log in as root and login failed. Could not log in with a username from NIS either. I decided (unwisely, it seems) to reboot. Upon reboot the various daemons in /etc/init.d/ are started and the machine seems (I say seems because I did not wait long enough to see if it really does) to hang while starting postgres (under /usr/local). As I see it, here are my options - * Try to see if the boot sequence is really hanging by giving it enouch time. If it manages to proceed with the rest of the boot sequence and gets me into the login prompt, I have to try my luck with loggin in as root. * If I am unable to log in as root, how do I fix what I did to nsswitch.conf? I was sensible enough to backup the old file before making the changes. I am unable to locate my emergency disk (or whatever it is called). Can I use the Debian 1.3 distribution's installation boot disks, mount /dev/sdb3 as root and fix the problem and then try rebooting with my regular custom boot disk? How? * Ideally, I'd prefer booting up into NT and being able to access the ext2 partition. I remember reading somewhere that there is a device driver for reading / writing into an ext2 partition for NT. Help me Obi Wan. You are my last hope. ;-) Sudhakar -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] . Trouble? e-mail to [EMAIL PROTECTED] .

Can I use the Debian 1.3 distribution's installation boot disks, mount /dev/sdb3 as root and fix the problem and then try rebooting with my regular custom boot disk? How? Yes, this is The Universal Way To Do It. It also explains why people wonder Why did they call the installation bootdisk `rescue disk'? Type at the lilo prompt linux root=/dev/where your root filesystem is If that doesn't work, try linux emergency root=/dev/blah. Or if even that fails, just hit enter and goto the second virtual console with alt-F2 and mount the /dev/blah on /mnt. You don't get to use emacs to edit the fsck'ed conffiles then though. * Ideally, I'd prefer booting up into NT and being able to access the ext2 partition. I remember reading somewhere that there is a device driver for reading / writing into an ext2 partition for NT. AFAIK it's still rather beta and read-only.

Rereading what you had written, it makes sense. What does compat give me as opposed to db files nis? I don't know if this is documented in the info files. (You need the debian package libc6-doc for this. Yes, this is not obvious.) Oooow! That hurt. ;-) Thanks again for all the folks who helped. I think hamm is quite stable. If you are contemplating an upgrade but have held back because of stability concerns, I suggest that you read the mini-HOWTO, grab the upgrade script and don't screw up (like I did).
