Hi,

I havce two questions:

1) How can I know how much space is left on my harddisk?

2) I have currently a RedHat system with a rather small harddisk. My plan is to install a larger harddrive in the same server and install Debian on that harddrive. The old 'RedHat' disk is supposed to go to another PC. My current RedHat system is already configured (Apache webserver, MySql database, PHP installed, webalizer, different crontabs, ...) How can I put this configuration data on my new Debian 'harddrive'.

Thanks in advance,

use the command 'df' (without quotes) on the cmd prompt.
type 'df --help' for options.. 'df -h' is good for a general view of space avail/remaining

1) You need to have the partitions mounted for this - to show usage for mounted partitions:
df -h
2) I wouldn't overwrite the configuration on your new server in case you use different versions that need different configs - merely use them as examples. Getting the data over shouldn't be a problem - just install debian on the new drive then mount the partitions from the old drive with the data on them and copy the files over.

How can I 'see' two harddrives in Linux, 1 has RedHat and the other has 'Debian'. How can I simply transfer files between them?

Once you have booted into debian create a temporary mount point - eg:
mkdir /mnt/rh9

Then mount the partition that has your data on it - eg:
mount /dev/hdb3 /mnt/rh9
