Allen, Still struggling with your login? On 11/21/2014 06:56 PM, Allen wrote: I hope this finds someone that can help. I have my user name and password written down, the system doesn’t like them anymore! you must have written it incorrectly. Make sure your Caps Lock is not on or numerical part of keyboard is not in edit mode. I have tried to get a new password and asked for my user name as suggested. I get no emails with either user name or password. Where is that suggestion coming from? This is not on some server or in the cloud where applications make it possible to recover from login problems. What now? Allen Bootup from CD or it's USB equivalent and select a rescue mode. That should make it possible to change the password. I don't remember where the root partition will be mounted by default if at all. Regardless, you need to open a terminal and run a command 'df' which would tell you if /dev/sda1 is mounted or not. If it's mounted, go to the mount point, /tmp/target for example, and edit file /tmp/target/etc/shadow. But let's assume you used Ubuntu CD to boot from and that the hard drive was not mounted. That happened in my test with LinuxCNC in virtual environment, Virtualbox. Open a terminal. You are going to be logged in as user ubuntu. You either need to prepend all suggested commands with sudo or become user root, my preference. Switch to user 'root' with command 'sudo su -'. Run the following commands one by one: fsck /dev/sda1 mkdir /tmp/sda1 mount /dev/sda1 /tmp/sda1 Now you should be able to run ls /tmp/sda1 That is disk drive partition 1 root or top point. You should see directory named etc among others in there. cd /tmp/sda1/etc cp shadow shadow.bkp-- creates a backup copy. ls shadow* -- command shows two shadow files in that directory. Most likely 3 as one is shadow~ also a backup created by the system at some point. Now edit file named shadow and remove the password, that is the part between the first and second ':' following your user name. In your case it might look like: allen:$6$K5NgZYUK$3s2qEljrPGeX4LLLyuVVDGjA104:15942:0:9:7::: ^ --- remove ^ Make sure you don't remove anything else. Save the file and reboot from the hard drive. You should be able to login without a password afterwards. Then change your password. Make sure you test login before you logout to prevent lockout again. For editor you can use either vi or nano. There are other ways to do it but that's the easiest IMO. The same would work for most if not all Linux distributions. -- Rafael -- Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!

Rafael, No, I have it squared away now. I didn't update my records and I was using the wrong info.
