PC-Leland Commands

The following commands can be selected from the PC-Leland menu:

About PC-Leland
Here you can find the version number of PC-Leland and other information about the product, plus a photograph of Hoover Tower and the Quad, taken by Don Geddis, a Stanford alumnus.

Help
The Help command opens the web-based help file that should be stored in the PC-Leland folder created as part of PC-Leland’s installation. The default browser on your computer will be launched to display a help page stored on your computer. From there, you can access the entire User Guide through the Internet.

Login
This command enables you to sign on. It verifies that you are a member of the Stanford community by requesting your SUNet ID and password. Unlike logging in to a particular computer, such as elaine, or Cardinal, PC-Leland enables you to sign on to multiple machines and services without having to enter a SUNet ID and password each time. When you enter them and press the OK button, PC-Leland passes this information (encrypted) to a Kerberos authentication server, which sends back a Kerberos ticket if the ID and password combination is correct. (See the PC-Leland FAQ section for more information.)

Renew Login...
To renew your Kerberos tickets before they expire and log you out from PC-Leland, you can choose this command, which again prompts you for your SUNet ID password.

Logout: SUNet ID
This command, which replaces Login on the menu when you are logged in, ends the PC-Leland session of the specified SUNet ID, discarding all Kerberos tickets that were created for that ID during the PC-Leland session. It does not affect any open Samson or Eudora sessions, but they will ask you to logon to PC-Leland again the next time you start a telnet session or check for new mail. (This will appear as Logout: followed by the specific SUNet ID that is logged in. For example, Logout: lelandjr or Logout: gcasper.)

Show Status
This command shows PC-Leland's status, including:

the Kerberos authentication tickets that are in effect for your PC-Leland session, with the time they were issued and the time when they will expire;
Stanford Web Authentication tickets that are in effect.

Change Password
This command lets you change the password associated with your SUNet ID. This is the same as changing your SUNet ID password at the Stanford.you web pages, or logging in to elaine-best.stanford.edu and issuing the passwd command.New passwords need to conform to the following rules:

It must be 7-40 characters long.
It must NOT be a word--not even a word in a foreign language.
You can't get around the "word rule" by adding one or two characters at the beginning or end of your password. (For example, 9cheval, 99cheval, cheval9 and cheval99 are invalid.)

If you're like most people, you choose a somewhat personal password and stick with it. These passwords can be made safe. For example, a password based on your cat's name could be disguised like so: flu77ffy, flu@#ffy, or Flu*&FFy. By adding capitals and random punctuation to the middle of a password, you can keep it safe AND memorable. See the SUNet ID passwords web page for more tips on creating a secure and memorable password.

Note: If you successfully change your password or if you cancel Change Password, you will be logged out of PC-Leland and must log in again to continue using PC-Leland. This is a current limitation to be addressed in a later release.If you have enabled Single Sign-on, PC-Leland will automatically change your Windows 95/98 password as well.

Lock PC
This command effectively disables your PC; no one else can use your PC until:

the last user enters their SUNet ID password, or
the PC is restarted

This gives you an easy way to lock your PC, protecting your PC-Leland session when you leave it temporarily. This is not a foolproof way to prevent your computer from being used. You can rely on this command to prevent others from using any PC-Leland enabled facilities, such as Eudora or Samson, on your PC with your SUNet ID. Note: In the PC-Leland Settings dialog box under the Security tab, you can find a setting to disable the Lock PC command so that no one using your PC can lock it.

Mount
Not used. Use Stanford OpenAFS to mount AFS directories.Stanford OpenAFS can be downloaded from the Essential Stanford Software web page.

Settings
This command brings up the Settings dialog box allowing you to configure PC-Leland to your specific needs. (See the PC-Leland Settings section of this document for more detailed information.)

Quit
This will close the PC-Leland program and destroy any existing kerberos tickets. To restart PC-Leland, select Programs -> Startup -> PC-Leland from the Windows Start menu or simply restart your computer.Note: In the PC-Leland Settings dialog box under the Menus tab, you can find a setting to disable the Quit command so that no one using your PC can quit PC-Leland.
