howto reset root password with setup disk (or some other way)
Hi people, for some dark reason is my rootpassword changed. does anyone know how I can reset the password for root? A while a go someone told me that this is possible by using the install-boot disc or cd's. I hope I will not have to reinstall my machine. All help and tips are welcome! kind regards and best wishes, Corry.

Delete the second field from root's entry in /etc/passwd (/etc/shadow if you're using shadow passwords - you'll have an x in the passwd file if you are). This will remove root's password, and you can reset it using passwd. A safer thing to do is to generate a new crypted password and directly replace the password, but unless you're on-line when you do this I wouldn't worry about it. -- Mark Brown mailto:[EMAIL PROTECTED] (Trying to avoid grumpiness) http://www.tardis.ed.ac.uk/~broonie/ EUFShttp://www.eusa.ed.ac.uk/societies/filmsoc/ pgpfQTAxaCMAF.pgp Description: PGP signature

yes, but there is one additional problem: Currently I'm not logged on as root.

If you can boot from install CD, there should be a shell session on some virtual console ( probably second ) with root's privileges.

Boot specifying init=/bin/bash on the kernel command line. If you have LILO, then say linux init=/bin/bash where linux is the name of the LILO option for Linux. If security features prevent you from doing this you should try booting via the rescue disk. Either get a shell from the installation system and mount your root partition or say linux root=root_partition init/bin/bash at the first prompt. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Mark Brown Sent: Sunday, July 23, 2000 13:38 Please quote properly: delete material not needed for context and place new text after old. -- Mark Brown mailto:[EMAIL PROTECTED] (Trying to avoid grumpiness) http://www.tardis.ed.ac.uk/~broonie/ EUFShttp://www.eusa.ed.ac.uk/societies/filmsoc/ pgpVN5pg3fd6d.pgp Description: PGP signature

Reboot the computer and enter at the LILO-Prompt 'imagename init=/bin/bash' imagename ist the name of the Kernel you want to boot. The default is linux. After this, remount / readwrite (with mount -n -o remount,rw /) and edit your /etc/shadow. Remove the crypted password for root (the second field. separator is ':'). Remount / readonly again (mount -n -oremount,ro /) and reboot the machine. Now you can log in as root without password. bye Gerhard -- Hi! I'm a .signature *virus*!

All help and tips are welcome! kind regards and best wishes, Corry. Try booting from anywhere (the Debian installation source is a good choice). Then mount the partition to which you mount / (the root file system). Next open mount_point/etc/passwd with some editor (ae if from the Debian install disks). Find the line which looks like this: root:x:0:0:root:/root:/bin/bash Change the x into , i.e. so that the line looks like root::0:0:root:/root:/bin/bash You no more have a password set for root so boot your machine and supply an empty one to log in. I also suggest reading passwd(1) :). Success, Pavel
