Re: [newbie] lost root password
when it comes up, in rescue mode, type: chroot /mnt Im not certain that's going to work... what is actually mounted at that point? His root partition? What chroot does is to change the root partition basically. Putting in NEWROOT is just a sample place, it's not meant to be taken literally. It's more like a variable. Eric, have you tried booting into failsafe mode? It's one of the choices on your menu, or at least it should be there. failsafe will put the box in single user mode (essentially the same thing as 'linux single' (which may not work.) Once you're in single user mode, you should be able to change the password for root 'passwd root' type the same password in twice, and then telinit 3 and login as root. Eric David E.

Eduardo At the LILO boot prompt, type : linux 1 the system will startup in single user mode, no need to login- you will already be root. You will have to make a new password for root, so just type: passwd and follow the prompts. Then just reboot (shutdown -r now) Good Luck Eunice Thompson

Re: [newbie] Lost root password
at the lilo prompt, try linux s or linux single on some systems this will boot the machine to a single user mode with no need to login, then you can run (if memory serves) 'passwd root' at the prompt and change the password for root some people think this is a security flaw in linux but i have read that this behaviour can be turned off and i believe is done so if mandrake is installed with 'high' security mode but i'm not sure about that, maybe someone can confirm or deny? hope this helps bascule [EMAIL PROTECTED] wrote: Hello Somehow I lost root password.

Re: [newbie] Lost root password
AMHA, An other way, or if single no more exist (Sorry Bascule, I doubt it can be done in this mode): Start with the boot and rescue disk (cd inserted). After the intro message (if message is), type exit. Mount a root partition on the HD, utilize fdisk -l to see the existing partitions. After mount it as /mnt/rootpart edit the file with the command: vi /mnt/rootpart/etc/passwd the first line will be: root:F.h5fh/fj4:0:0/root:/bin/bash With the x key delete all the chars between roo: and :0:0 Must be: root::root:/root:/bin/bash Save with ZZ (vi command) Verify with cat /mnt/rootpart/etc/passwd Then unmount as umount /mnt/rootpart Type exit and Ctrl+Alt+Del Now after boot you are connected as root but without password. Simply type passwd to set a new password for root. Hope I didn't forget somewhat.eh Eric bascule wrote: at the lilo prompt, try linux s or linux single on some systems this will boot the machine to a single user mode with no need to login, then you can run (if memory serves) 'passwd root' at the prompt and change the password for root some people think this is a security flaw in linux but i have read that this behaviour can be turned off and i believe is done so if mandrake is installed with 'high' security mode but i'm not sure about that, maybe someone can confirm or deny? hope this helps bascule [EMAIL PROTECTED] wrote: Hello Somehow I lost root password.
