+Drugi razdelek na sliki smallstudent-personal priklopi na imenik {mntdir}
+
+Na SimpleArbiterExam se lahko prijaviš z uporabniškim imenom tester in geslom test.
+Na SmallStudentExam se lahko prijaviš kot root z geslom kaboom.
+
+Poskrbi, da bo SmallStudent s SimpleArbiter dostopen na naslovu {testip}.
+
+Na SmallStudent ustvari uporabnika {testuser} z geslom {passwd}.
+
+Na smallstudent-personal je nekje skrita
+datoteka, ki vsebuje niz {magicstr}.
+Skopiraj jo v domači imenik {testuser} in preimenuj tako, da vse znake 'O' v imenu zamenjaš z 'I'.
+Pazi, da nobena druga datoteka v domačem imeniku v svojem imenu ne bo vsebovala "I".
+
+Poskrbi, da bo lastnik {testuser}, skupina pa naj ostane nespremenjena.
+Brati naj jo ima pravico samo lastnik, pisati lastnik in skupina, poganjati nihče.</pre>
