You can download the forms you need from the accounts page. You will also need Adobe Acrobat to view and print these forms. There is a link to the Acrobat software on the same page as the applications.
To change your password log on to one of the suns (such as nebo.essc.psu.edu) and issue the command yppasswd. Good passwords are ones that contain at least one non-alpha-numeric character as well as perhaps a change of case and are not a word that can be looked up in a dictionary or can be associated with you, such as your first-born's name.
A quota is a disk storage limit that is placed on an account to ensure that a user does not accumulate too much data in their home directory.
Here at ESSC, everyone shares their home directory space with other users. Home directories are meant to be used as an area to store configuration files and small amounts of e-mail and personal files. (Separate work directories can be provided for those users that need them to store larger amounts of data, code, and other work files.) Previous to the institution of disk quotas, anyone could use up all the space on the home directory disks. Not only was this inconsiderate to other users, it also caused many problems on the system.
Our solution has been to place a limit on the amount of information any user can have in his or her home directory at any point in time. Attempting to go over this limit results in the same error that writing to a full disk would give.
There is an easy way to keep track of how much space you have and how much you are using -- the "quota" command.
The command:
quota -v
will give a listing of how many kilobytes of storage you are currently using and how much you could ultimately take up (ie., your quota). For example:
odo:demark[73]% quota -v Disk quotas for demark (uid 24098): Filesystem usage quota limit timeleft files quota limit timeleft /home/essc 3507 20000 30000 951 0 0 odo:demark[74]%
User demark has a quota of 20000 Kb (~ 20 Megabytes); this is how much disk space he can use to store files in his home directory. Currently, only 3507 kilobytes are actually being used by him. He also has a limit of 30000 Kb. For short periods of time, he can exceed his 20000 Kb quota, up to the 30000 Kb limit. But, if he exceeds 20000 Kb for more than a few days, the system will no longer allow him to create any new files or add to old ones until his usage drops below 20000 Kb again. The 30000 Kb limit is absolute; there is no way demark can have more than 30000 Kb in his home directory -- as far as the system is concerned, it would look like demark is attempting to write to a full disk if he tries to surpass that limit.
If you do exceed your quota, the system will alert you to this fact when you log in. It will also tell you the number of days remaining until the system "cuts you off" and stops you from creating new files or adding to old ones.
Remember, you have to keep the "usage" value less than the "quota" value almost all the time. You may only exceed the "quota" value for short periods of time. It is impossible to exceed the "limit" value.
