anyone to connect to your X-server.

contains the /etc/foo file?

C. rpm -qlf /etc/foo

using the rpm -q -f command. You must have the redhatrpmdb

rpm installed though.

configured. What command can you use to find out what kind of

graphics card it has?

errors?

A. mount

B. test

period for quotas?

A. quotaconfig -g

group. You can say edquota -t to set up grace periods.

wrong becuase the device should be /dev/fd0 rather than

/dev/floppy.
