==Managing your password==
 
CAC has a [[Getting_Started#Rules_for_creating_passwords|password policy]] in effect. The first time that you login to the <tt>cac.cornell.edu</tt> domain, you will be required to change your password. Each password must have at least eight characters and must contain at least three of the following four elements: (1) uppercase letters (2) lowercase letters (3) special characters (4) digits. Your password can be set or changed on any of the CAC login nodes, and the password will be updated on all CAC resources. Passwords expire every six months. Do not share your password. There are more detailed instructions below.

=== Locked Accounts===
 
 
 
There have been instances in which user accounts have been locked. Some common causes of locked accounts and the solutions are:
 
 
 
:*Mistyping your password several times in a row.
 
:::<tt>Solution</tt>: Wait about a 1/2 hour and then try again. Be sure that your caps lock key is not on!
 
:*Trying to login to a Windows login node by using SSH when you have a new or expired password.
 
:::<tt>Solution</tt>: Login to a Windows login node using Remote Desktop Connection or SSH to a linux login node.
 
:*Failing to log off all other sessions connected to login nodes.
 
:::<tt>Solution</tt>: Log off all remote connections. Disconnecting the sessions is not enough.
 
:*Failing to disconnect locally mapped drives to the CAC file server before changing your password.
 
:::<tt>Solution</tt>: Disconnect all locally mapped drives, wait a 1/2 hour until account is unlocked, and then re-map the drive with the new password.
 
 
 
If you can't log on or can't wait you can submit a Password Reset ticket on our [https://rt.cac.cornell.edu/index.html issue tracking system]
 
 
 
==Checking your CAC project ==
 
Cornell University users can view their account limits at [https://{{SERVERNAME}}/services/cu/memberlimits.aspx CAC Account Limits].<br />
 
Partner Program members should contact Paul Redfern at [mailto:red@cac.cornell.edu red@cac.cornell.edu] if they need information on their membership limits.
 
 
 
==Using CAC resources==
 
 
 
'''Please see the [[Red Cloud]] and [[OpenStack]] pages for information on connecting to and using Red Cloud resources.'''
 
 
 
CAC also maintains private clusters (for particular research groups) and provides data storage services.
 
 
 
The information on the remainder of this page is potentially of interest to users of any of CAC's services.
 
 
 
===Connecting to CAC Login Nodes ===
 
 
 
There are three types of login nodes:
 
:* The head nodes for the various Linux-based private clusters
 
:* Linux login node: <tt>linuxlogin.cac.cornell.edu</tt>
 
:* Windows login node: <tt>winlogin.cac.cornell.edu</tt>
 
 
 
The general CAC login nodes, linuxlogin and winlogin, are mostly intended for researchers who are have procured CAC storage services, apart from Red Cloud and private clusters (see [[Getting Started#Home Directory Access|Home Directory Access]]). These two login nodes are broadly accessible from the Internet, and they provide a convenient way for researchers to gain access to their files. On the general login nodes, you will find a modest number of software tools installed to aid in working with files (but please do not use these tools for doing production computing there).
 
 
 
In what follows, we will often use '''''linuxlogin''''' and '''''winlogin''''' as stand-ins for the particular CAC servers that you are trying to access (e.g., in a private cluster or in Red Cloud).
