+   * After you install DRBL server, you can follow the example when you execute "drblpush -i" to set up the client environments. Each machine need a host certificate for Globus, and its hostname needs to be fixed. In order to avoid modifying some congifuration files(ex:/etc/hosts) erery time and avoid starting Globus unsuccessfully, you need to let the DHCP service in DRBL server offer same IP address to the client every time when client boots.[[BR]][[BR]]

+******************************************************
+Now we can collect the MAC address of clients!
+If you want to let the DHCP service in DRBL server offer same IP
+address to client every time when client boot, and you never did this
+procedure, you should do it now!
+If you already have those MAC addresses of clients, you can put them
+into different group files (These files number is the same number of
+networks cards for DRBL service). In this case, you can skip this
+step.
+This step helps you to record the MAC addresses of clients, then
+divide them into different groups. It will save your time and reduce
+the typos.
+The MAC addresses will be recorded turn by turn according to the boot
+of clients,
+and they will be put into different files according to the network
+card in server, file name will be like macadr-eth1.txt,
+macadr-eth2.txt... You can find them in directory /etc/drbl.
+Please boot the clients by order, make sure they boot from etherboot or PXE!
+Do you want to collect them ?

+them in file(s) (as in the previous procedure)). This is for the
