Linux Desktops¶
All desktops in the Oden Institute run Ubuntu 18.04 LTS. In addition to the default features, Sysnet has added a number of improvements.
Miscellaneous Tasks¶
Password Change¶
Important
We suggest reviewing Sysnet’s policy on password rules before changing your password.
Visit our Password Change page.
Change login shell¶
Please submit a help request to RT to change your shell.
Retrieving backups of home directory¶
Often times you can accidentally misplace or delete an important file. If you are in a situation where a file you need is missing it may be worthwhile to look through the snapshot directory for backups.
In your desktop menu, select
Make sure you have hidden files enabled by choosing
Scroll down to a folder called .snapshots
and open it.
You will see a series of folders with numbers on them. These represents
the different dates the backups were taken in yyyy/mm/dd format. Choose
a recent time and open the folder. There will be a folder inside named
tree
. Open it and you will see a copy of all your files in the home
folder from the time period indicated on the parent folder.
Simply copy whatever files you need to your current home folder to restore them.
Unencrypting /workspace¶
The /workspace partition on managed desktops is encrypted along with the swap space. When logging into a desktop’s console after a reboot, the encrypted partitions must be unencrypted, you will be prompted twice, once to log into the workstation, then a second time to unencrypt the partitions.
If your remotely log into a workstation and need access to /workspace, be aware that it might not have been unencrypted. If you see the file:
/workspace/WORKSPACE_IS_NOT_MOUNTED
This means the workspace has NOT been unencrypted. To unencrypt /workspace, issue:
sudo /usr/local/sbin/deluks
This will prompt for your Oden Institute credentials to unencrypt the encrypted partitions.
