+Ustvari dva navidezna računalnika s slikama diskov
+- SimpleArbiter s sliko diska simpleArbiterDhcp in
+SmallStudent s sliko diska student-entrance2.
+
+Na SimpleArbiter se lahko prijaviš z uporabniškim imenom tester in geslom test.
+Na SmallStudent 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 {pass}.
+
+Na SmallStudent je nekje v domačem imeniku uporabnika "bilbo" skrita datoteka, ki vsebuje niz {magicstr}.
+Skopiraj jo v domači imenik {testuser} in poimenuj {dstfile}.
+Poskrbi, da bo lastnik {testuser}, skupina pa naj ostane nespremenjena.
+Brati naj jo ima pravico samo lastnik.
+V {dstfile} zamenjaj vse vrstice oblike poXYZlz, kjer so XYZ poljubni znaki, tako, da bo namesto XYZ niz "kaka".
+
+Napiši program v poljubnem programskem jeziku, ki kot argument sprejme število B med 0 in 7.
+Program naj prebere znak s standardnega izhoda in izpiše vrstico z nizom "ta",
+če je B-ti bit v znaku nastavljen na 1, in "ti" sicer.
+Program poimenuj {progname} in ga spravi v domači imenik {testuser}.

+Create two virtual machines
+- SimpleArbiter using simpleArbiterDhcp as the disk image and
+SmallStudent using student-entrance2 as its disk.
+
+You can log in as testr on SimpleArbiter with the password test.
+You can log in as root on SimpleStudent with the password kaboom.
+
+Make sure that SmallStudent is accessible from SimpleArbiter on IP {testip}.
+
+Create a user {testuser} with the password {pass} on SmallStudent.
+
+There is a file containing {magicstr} hidden somewhere in the home directory of
+user "bilbo".
+Copy the into the home directory of user bilbo and name it {dstfile}.
+Change the owner to {testuser} and leave the group unchanged.
+Make sure only the owner has the right to read it.
+In {dstfile}, replace all lines of the form poXYZlz where XYZ are arbitrary characters so that XYZ is replaced by "kaka".
+
+Write a program in any programming language.
+The program should accept a single argument, B, which is a number between 0 and 7.
+It should read a character from standard input and output "ta" if B-th bit in this character is
+set to 1. If B-th bit is not set, the program should output "ti".
+Name the program {progname} and place it in the home directory of {testuser}.
