The initial password assigned to your account is the password that you specified when you requested your Koti account. If you do not remember your password, please contact the VCU IT Support Center (828-2227 or email@example.com) for assistance.
It is your responsibility to keep your password private and secure, as you would any valuable information.
For security purposes, you are encouraged to change your Koti password at least every few weeks or months, using the procedure discussed below.
Note that your Koti password is not tied to your eID password (that you use for VCU email). That is, if you change your Koti password, that does not also change your eID password, and vice versa. Because Koti houses sensitive data, you should make your Koti password different from your eID password.
Changing your password:
To change your Koti password, login to your Koti account (as described below) and issue the following command at the command prompt:
and then follow the directions presented. First, you will be asked to type your current password and press Enter (for security, you will not see anything displayed on the screen as you type). Then, you will be asked to type a new password. Finally, you will be asked to re-enter the new password.
Your new password must:
You are also encouraged to include special characters in your password, such as '$' or '%' or blank spaces, however they are not required.
If you have not changed your password for 6 months, the Koti system will force you to change your password the next time you attempt to login. At that time, when you attempt to login, just after you enter your current password you will be asked to enter a new password. Your new password must follow the rules shown above.
Logging into Koti is a 2-step process:
When you are finished using Koti, be sure to logout by issuing the 'logout' command.
There is a 2 hour inactivity timeout on Koti. If there is no activity in your Koti session for 2 hours (approximately), you will be logged out of Koti. You will, however, remain connected to the VPN, so you can immediately log back in to Koti.
After you login to Koti, you will see a "command prompt" displayed. Here is an example prompt:
Inside the square brackets, you see your account name (e.g., "jdoe") followed by "@koti", and you see the name of your current directory (the "~" tilde is a symbol that represents your home directory). If you change your current directory, your new directory will then be displayed in the command prompt. At the far right of the prompt is a "$" dollar sign.
When you see the command prompt, you may type a command and press the Enter key to request Koti to execute that command. Depending on the command, while it is running (executing) it may display information on your screen. When the command completes execution, you will receive another command prompt, so that you can then issue another command.
When you are finished executing commands, you should issue the "logout" command to end your Koti session. Note that if you do not type any commands for a 2 hour period (approximately), you will be automatically logged out.
If you need to execute a command or program that will run for an extended period of time, you can execute it "in the background" by simply typing an "&" ampersand at the end of the command. When you do that, you will immediately receive another command prompt (so that you can issue other commands or even logout), and your command or program will continue running (in the background) until it finishes. For more information on this, including how to determine whether your command has finished, please see "Submit A SAS Program To Run In The background" (although that discusses executing the "sas" command in the background, the procedures described are similar for any command).
There are may commands that you can issue for launching software packages or performing various tasks on Koti.
Here is information about some of the software and commands that are available on Koti. Note that Koti currently runs the Red Hat RHEL 6 Linux operating system, which is a form of Unix.
Text editors available on Koti include:

To transfer files between your computer and Koti, you can use either the MobaXterm, XQuartz, or Terminal program, noted above in Logging in to your account. However, login using this command (replace jdoe with your Koti account name):
You will receive an sftp> prompt, at which you can issue commands.
To see a list of available commands, type a question mark "?" and press Enter.
When finished with your session, issue the quit command.
Drag and drop: Additionally, if you use MobaXterm and login using the ssh command (see Logging in to your account above), you can transfer files by dragging and dropping files to and from the "Sftp" pane. located on the left side of the MobaXterm window.
