- Download Webmin and install it on the machine on which you wish to enable quotas. It might be a little difficult for some people, but just read the instructions and you will have no problems.
- Login to Webmin, click on the System button, then click on the Disk quotas button.
- Choose the filesystem where you want disk quotas enabled, and click the Enable Quotas link. Then choose users and set your quotas.
Using webmin, I was able to set up disk quotas for five users in less than 10 minutes.
[robg adds: I'm sure someone will volunteer the command-line solution to this problem, but Webmin seems like an easy way to accomplish the same results. We've run a few hints about Webmin in the past (Original hint, Revised original hint, Secure Webmin with SSL) ... if you haven't checked it out, it's well worth a look.]
