 The stat command: this shows the size of the iSCSI LUN as if it was a normal file:

 The cat command, which allows you to read/dump a iSCSI LUN to a file :
-$ LD_PRELOAD=./bin/ld_iscsi.so cat iscsi://127.0.0.1:3262/iqn.ronnie.test/2 >copy_of_iscsi_lun

 Or using dd even :
-$ LD_PRELOAD=./bin/ld_iscsi.so dd if=iscsi://127.0.0.1:3262/iqn.ronnie.test/2 of=copy_of_LUN bs=10M count=1
+$ LD_PRELOAD=ld_iscsi.so dd if=iscsi://127.0.0.1:3262/iqn.ronnie.test/2 of=copy_of_LUN bs=10M count=1
 
 The LD_PRELOAD hack is incomplete and needs more functions to be intercepted
 before becoming fully functional. Patches welcome!
