What's the default username and password for an Ubuntu Live CD?

What's the username and password for an Ubuntu Live CD image?

I ask because I've recently copied the contents of an Ubuntu based live ISO (easypeasy, the ldistro for nwtbooks) onto a hard disk drive, but the Squashfs file system is corrupt, most likely because I copied it live. :) So it's not autologging in. Is there a username/password for this?

Update: I tried username Ubuntu and a blank password, and it didn't work.

Solution 1:

Try 'ubuntu' with an empty password. If that doesn't work, you're probably best recopying the squashfs.

Note that squashfs is readonly, I assume you mean you copied the unionfs that lies on top of the squashfs and the tmpfs?

Solution 2:

If the username "ubuntu" with an empty password doesn't work, you may be able to add a new user to the system as follows:

1. Boot from a live CD, and start a terminal session.
2. Mount your hard drive partition somewhere, like /mnt (i.e. mount /dev/hda1 /mnt)
3. chroot /mnt
4. adduser username
5. Reboot

Solution 3:

I'm not sure what the answer is, but I've solved this another way, so it's not a problem for me anymore. I discovered recently that it's possible to disable the password for an account. You can do this to force ssh key logins. I suspect that's what's going on here.
