You have the following privileges and limitation on the use of your mama account:

1. Courtesy account users have an un-enforced quota of 50 MB of disk space (this includes your personal/home directory plus your web/homepage directory). Un-enforced means that there is no real restriction on the amount of space you may take so long as you do not go over 50 MB for more than a day and you do not take so much space as to fill up the hard drive. Enforcement of this policy is by root who reserves the right to delete stuff if you're over quota and it becomes necessary to free space on the drive.

   To see how much space you're using, run the "diskhogs" command or use: "du -s ~" for a up to date usage summary.

2. You have an un-enforced quota of 1 MB of mail space. The limitation on mail usage is because if the partition that mail is stored on becomes full, mail delivery becomes impossible and mail will be lost. If you save the message (which removes it from the INBOX) the message moves from the mailspool partition and is stored in your personal/home directory; this allows you to store all of the old mail you desire (within the space limits of item 1 above). Use mailhogs to determine how much of the system's mail partition you are using.

3. Reasonable use of CPU time. This means that compiling gcc, ray-tracing a movie, and computing pi to the millionth decimal place all at the same time so as to seriously degrade system performance is considered a no-no.

4. Reasonable use of Modems. There are a large number of courtesy account users and a limited number of modems. We do not enforce limits on modem use ... yet. If abuse of the priviledge of using the modems attached to the Department of Life Sciences' servers becomes a problem, we will set maximum time limits, maximum connections per day, maximum idle time limits, or whatever restrictions required to prevent abuse. As long as courtesy account users respect the needs of other users, we will not impose limits on use (we do not wish to be "policemen").
