Hello
I'm quit new for LINUX.

My , Red Hat Linux kernel version is 2.4.20-8

AND
It boots with GRUB boot loader version 0.93

I did not use linux for few months and I fogot root password. Now I have no account. Is there any way to recover root password with using floppy.

you just need to boot into single user mode. I know it's a redhat manual, but this is for booting in either grub or lilo. so anyway, boot into single user mode and then you can use the passwd command to create a new password.

edit: if you've set a grub password, i hope you know it or else the only other way I can think of is to use a live cd and mount the hard drive and manually delete the password portion of the root entry in /etc/passwd or /etc/shadow if you're using password shadowing.

By the way, don't use the root account. If you have no other accounts on the system that's bad. You should only use the root account when absolutely necessary. It's especially bad to use the root account to go on the Internet.

hi,
with your bootable floppy of linux or with the first cd of linux, enter in rescue mode. After you entered in single user mode, please type command
chroot /mnt/sysimg
now open file /etc/passwd, in this file there is a line like:
root:x:..................................
remove this x that is after root and save the file.
now open file /etc/shadow, in this file there is a line like:
root:asdf45traf2345asf:............................
remove whatever appear between these two column. save the file and restart the system with the hdd.
now you are not require to enter root password, only press enter when it asks for password.

name the browser which will run on uClinux
