Õppejõud:

Katrin Loodus (katrin.loodus@itcollege.ee)

Ruum 516 (V korrus), sisetelefon (6285) 834

ÕISis olev õppematerjali viide viitab siia lehele! Eraldi loenguid ÕISi ei laeta, kuna: Kui teed ainet järele ja ei deklareeri, siis sa ei näe ÕIS'is asuvaid materjale. Aine viki on üks ja ainus, kuht kuhu kõik koondub ja eraldi asuvad materjalid (kontrolltööd, eksamid jne on siit lehelt viidatud)

=Sissejuhatus=

Kursus annab põhiteadmised ja praktilised oskused olulisemateks tegevusteks operatsioonisüsteemide haldamisel. Käsitletakse kasutajate, failisüsteemide, protsesside ja tarkvara haldamist, õiguste andmist, seadmete konfigureerimist, ketaste kasutuselevõttu, operatsioonisüsteemi installeerimist ja käivitumise juhtimist, varunduse ja taastamise korraldamist, turvaprobleeme ning võrguteenuste konfigureerimist.

Loengutes käsitletakse üldiseid teadmiseid. Praktikumides omandatakse oskused ühe konkreetse süsteemi abil, milleks on Ubuntu Linux Server.

'''Aines on pandud suurt rõhku praktilisele tööle.'''

Aine läbinud õppur teab:
* Operatsioonisüsteemide administreerimise põhialuseid

Aine läbinud õppur oskab:

* Hallata kasutajaid ja gruppe Linux laadsetest süstemides

* Töötada failide ja kataloogidega (varundada, seada õiguseid)

* Hallata ja paigaldada tarkvara Ubuntu Linux Server keskkonnas (deb ja apt baasil ka teistes distributsioonides)

* Hallata Linux käsurea abil servereid

* Hallata Linux serverite kettaid (luua, muuta kettajagusid ja saalelasid)

* Suudab leida üles programmide konfiguratsioonifailid ja log failid, ning lahendada lihtsamaid probleeme, mis süsteemide halduses igapäevaselt esile kerkivad

Õppejõud:

Katrin Loodus (katrin.loodus@itcollege.ee)

Ruum 516 (V korrus), sisetelefon (6285) 834

ÕISis olev õppematerjali viide viitab siia lehele! Eraldi loenguid ÕISi ei laeta, kuna: Kui teed ainet järele ja ei deklareeri, siis sa ei näe ÕIS'is asuvaid materjale. Aine viki on üks ja ainus, kuht kuhu kõik koondub ja eraldi asuvad materjalid (kontrolltööd, eksamid jne on siit lehelt viidatud)

=Sissejuhatus=

Kursus annab põhiteadmised ja praktilised oskused olulisemateks tegevusteks operatsioonisüsteemide haldamisel. Käsitletakse kasutajate, failisüsteemide, protsesside ja tarkvara haldamist, õiguste andmist, seadmete konfigureerimist, ketaste kasutuselevõttu, operatsioonisüsteemi installeerimist ja käivitumise juhtimist, varunduse ja taastamise korraldamist, turvaprobleeme ning võrguteenuste konfigureerimist.

Loengutes käsitletakse üldiseid teadmiseid. Praktikumides omandatakse oskused ühe konkreetse süsteemi abil, milleks on Ubuntu Linux Server.

'''Aines on pandud suurt rõhku praktilisele tööle.'''

Aine läbinud õppur teab:
* Operatsioonisüsteemide administreerimise põhialuseid

Aine läbinud õppur oskab:

* Hallata kasutajaid ja gruppe Linux laadsetest süstemides

* Töötada failide ja kataloogidega (varundada, seada õiguseid)

* Hallata ja paigaldada tarkvara Ubuntu Linux Server keskkonnas (deb ja apt baasil ka teistes distributsioonides)

* Hallata Linux käsurea abil servereid

* Hallata Linux serverite kettaid (luua, muuta kettajagusid ja saalelasid)

* Suudab leida üles programmide konfiguratsioonifailid ja log failid, ning lahendada lihtsamaid probleeme, mis süsteemide halduses igapäevaselt esile kerkivad

Ruum 516 (V korrus), sisetelefon (6285) 834

ÕISis olev õppematerjali viide viitab siia lehele! Eraldi loenguid ÕISi ei laeta, kuna: Kui teed ainet järele ja ei deklareeri, siis sa ei näe ÕIS'is asuvaid materjale. Aine viki on üks ja ainus, kuht kuhu kõik koondub ja eraldi asuvad materjalid (kontrolltööd, eksamid jne on siit lehelt viidatud)

=Sissejuhatus=

Kursus annab põhiteadmised ja praktilised oskused olulisemateks tegevusteks operatsioonisüsteemide haldamisel. Käsitletakse kasutajate, failisüsteemide, protsesside ja tarkvara haldamist, õiguste andmist, seadmete konfigureerimist, ketaste kasutuselevõttu, operatsioonisüsteemi installeerimist ja käivitumise juhtimist, varunduse ja taastamise korraldamist, turvaprobleeme ning võrguteenuste konfigureerimist.

Loengutes käsitletakse üldiseid teadmiseid. Praktikumides omandatakse oskused ühe konkreetse süsteemi abil, milleks on Ubuntu Linux Server.

'''Aines on pandud suurt rõhku praktilisele tööle.'''

Aine läbinud õppur teab:
* Operatsioonisüsteemide administreerimise põhialuseid

Aine läbinud õppur oskab:

* Hallata kasutajaid ja gruppe Linux laadsetest süstemides

* Töötada failide ja kataloogidega (varundada, seada õiguseid)

* Hallata ja paigaldada tarkvara Ubuntu Linux Server keskkonnas (deb ja apt baasil ka teistes distributsioonides)

* Hallata Linux käsurea abil servereid

* Hallata Linux serverite kettaid (luua, muuta kettajagusid ja saalelasid)

* Suudab leida üles programmide konfiguratsioonifailid ja log failid, ning lahendada lihtsamaid probleeme, mis süsteemide halduses igapäevaselt esile kerkivad

==Kodutööde/Iseseisvate tööde info==

Iseseisev töö toimub grupitöö vormis.Tudengid uurivad elulistel olukordadel põhinevaid juhtumeid ning pakuvad neile omalt poolt aine käigus omandatud teadmiste põhjal lahendusi. Uurimisele kuuluvad juhtumid on õppejõu poolt (edastatakse grupijuhi meilile). Iseseisva töö tulemusena valmib lühikokkuvõte probleemist, selle olemusest ning pakutud lahendusest, mis omakorda kantakse kaastudengitele suuliselt ette.
Töö orienteeruv maht on 2-4 lk teksti ning ettekandele kulub orienteeruvalt 15 minutit grupi
kohta. Grupis võiks olla 2-3 inimest.

==Arvestuse kujunemine==

'''Arvestuse''' saamiseks peavad olema tehtud:
1) suuliselt kaitstud '''kolm''' (seitsmest) laborites tehtavast praktilisest ülesandest
2) päevaõpe: kantud ette grupitööna valminud iseseisev töö (juhtumiuuring).
2) kaugõpe: kantud ette individuaaltööna valminud ettekanne või viki artikkel ainet puudutaval teemal

'''Boonuspunkte''' saab:

1) Teistele teema kohta ettekande tegemise eest (kogemuse jagamine)
2) Huvitavate praktikumi ülesannete välja mõtlemise eest
3) Praktikumis, õppejõuga kokkuleppel, kaastudengite juhendamise eest
4) LUGil ettekande tegemise eest

==Kodutööde/Iseseisvate tööde info==

Iseseisev töö toimub grupitöö vormis.Tudengid uurivad elulistel olukordadel põhinevaid juhtumeid ning pakuvad neile omalt poolt aine käigus omandatud teadmiste põhjal lahendusi. Uurimisele kuuluvad juhtumid on õppejõu poolt (edastatakse grupijuhi meilile). Iseseisva töö tulemusena valmib lühikokkuvõte probleemist, selle olemusest ning pakutud lahendusest, mis omakorda kantakse kaastudengitele suuliselt ette.
Töö orienteeruv maht on 2-4 lk teksti ning ettekandele kulub orienteeruvalt 15 minutit grupi
kohta. Grupis võiks olla 2-3 inimest.

==Arvestuse kujunemine==

'''Arvestuse''' saamiseks peavad olema tehtud:
1) suuliselt kaitstud '''kolm''' (seitsmest) laborites tehtavast praktilisest ülesandest
2) päevaõpe: kantud ette grupitööna valminud iseseisev töö (juhtumiuuring).
2) kaugõpe: kantud ette individuaaltööna valminud ettekanne või viki artikkel ainet puudutaval teemal

'''Boonuspunkte''' saab:

1) Teistele teema kohta ettekande tegemise eest (kogemuse jagamine)

==Kodutööde/Iseseisvate tööde info==

Iseseisev töö toimub grupitöö vormis.Tudengid uurivad elulistel olukordadel põhinevaid juhtumeid ning pakuvad neile omalt poolt aine käigus omandatud teadmiste põhjal lahendusi. Uurimisele kuuluvad juhtumid on õppejõu poolt (edastatakse grupijuhi meilile). Iseseisva töö tulemusena valmib lühikokkuvõte probleemist, selle olemusest ning pakutud lahendusest, mis omakorda kantakse kaastudengitele suuliselt ette.
Töö orienteeruv maht on 2-4 lk teksti ning ettekandele kulub orienteeruvalt 15 minutit grupi
kohta. Grupis võiks olla 2-3 inimest.

==Arvestuse kujunemine==

'''Arvestuse''' saamiseks peavad olema tehtud:
1) suuliselt kaitstud '''kolm''' (seitsmest) laborites tehtavast praktilisest ülesandest
2) päevaõpe: kantud ette grupitööna valminud iseseisev töö (juhtumiuuring).
2) kaugõpe: kantud ette individuaaltööna valminud ettekanne või viki artikkel ainet puudutaval teemal

'''Boonuspunkte''' saab:

1) Teistele teema kohta ettekande tegemise eest (kogemuse jagamine)
2) Huvitavate praktikumi ülesannete välja mõtlemise eest
3) Praktikumis, õppejõuga kokkuleppel, kaastudengite juhendamise eest
4) LUGil ettekande tegemise eest

==Kodutööde/Iseseisvate tööde info==

Iseseisev töö toimub grupitöö vormis.Tudengid uurivad elulistel olukordadel põhinevaid juhtumeid ning pakuvad neile omalt poolt aine käigus omandatud teadmiste põhjal lahendusi. Uurimisele kuuluvad juhtumid on õppejõu poolt (edastatakse grupijuhi meilile). Iseseisva töö tulemusena valmib lühikokkuvõte probleemist, selle olemusest ning pakutud lahendusest, mis omakorda kantakse kaastudengitele suuliselt ette.
Töö orienteeruv maht on 2-4 lk teksti ning ettekandele kulub orienteeruvalt 15 minutit grupi
kohta. Grupis võiks olla 2-3 inimest.

==Arvestuse kujunemine==

'''Arvestuse''' saamiseks peavad olema tehtud:
1) suuliselt kaitstud '''kolm''' (seitsmest) laborites tehtavast praktilisest ülesandest
2) päevaõpe: kantud ette grupitööna valminud iseseisev töö (juhtumiuuring).
2) kaugõpe: kantud ette individuaaltööna valminud ettekanne või viki artikkel ainet puudutaval teemal

==Lecture 14 and Lecture 9==

May '''17th''' 2016 - Lecture 14 - Miscellaneous topics (will be held in a computer class 319)

May '''19th 2016 at 10:00 in room 320''' - Lecture 9 - Monitoring (substitute lecture)

==Lecture 15==
May 24th 2016 - Lecture 15 - working in IT - merits and demerits

We will not have a lecture in the ordinary sense, instead we'll have a seminar or discussion on important aspects of working in IT. The ethical, social and personal aspects of it. Terms like "imposter syndrome", burnout, teamwork and better work environment will be some of the topics covered. Life is not only technical competence, it's a lot about human interaction as well.

=Lab works=

==Lab 0==

Installing Ubuntu Server 14.04.3 LTS

'''Introduction to Unix command line''' (cd, ls, cat, full path, relative path etc)

==Lab 1==

3 points - '''Managing users''' (adduser, addgroup, passwd, /etc/passwd, /etc/shadow)

1) Create a user noodle

2) Add a new group food and add a the user noodle to a group called food.

3) Divert the user noodle's password hash via cowsay to a file called cownoodle.txt.

4) Lock the user noodle and be ready to show me the indication of the user being locked.

5) Change the user's current home directory into /home/unknown so that the files will also be moved to the new location.

5 points - '''Managing files''' (mkdir, cp, mv, rm, touch, nano, less, chmod, chown, rwx, 644 etc)

1) Create a folder march in root user directory and for every march day a subfolder with a name day1, day2, day3 … day31. (Example: /root/march/day1 or /root/march/day2 etc)

2) Modify the march folder owner so that it will be student and the new group audio.

3) Modify the march folder's and its subfolders so that the user can do anything, group can do ls in the folder and cd into it and others can't do anything with it.

4) Create a hard link called network to a file /etc/network/interfaces

5) Copy /var/log directory into march folder so that the timestamp and user info will be preserved.

4 points - '''Processes and environment variables''' (kill, using directing input/output/error: |, <, >, >>; env, PATH, HOME etc)

1) Divert the list with the student user's groups via cowsay into a fail studgroup.txt.

2) Create a environment variable called MYHOME that has the value of the system's HOME environment variable. (Hint: you have tu use variable symbol here!)

3) Send 2 htop's to the background and be ready to present how you send a kill signal to the first htop by job number and term signal to the second htop by a process number.

4) Create an alias called bye that logs you out of the terminal. Make this alias permanent.

5) Execute a programm called espdiff and diver the standardoutput to a file called okay.txt and the standard error to a file called notokay.txt.

3 points - '''Managing software''' (installation, updating, deleting, apt and dpkg utils)

==Lab 2==

7 points -
'''Managing disks by creating partitions''' (fdisk, mkfs, blkid, mount, umount)

5 points -
'''Managing swap''' (mkswap, swapon, swapoff)

==Kodutööde/Iseseisvate tööde info==

Iseseisev töö toimub grupitöö vormis.Tudengid uurivad elulistel olukordadel põhinevaid juhtumeid ning pakuvad neile omalt poolt aine käigus omandatud teadmiste põhjal lahendusi. Uurimisele kuuluvad juhtumid on õppejõu poolt (edastatakse grupijuhi meilile). Iseseisva töö tulemusena valmib lühikokkuvõte probleemist, selle olemusest ning pakutud lahendusest, mis omakorda kantakse kaastudengitele suuliselt ette.
Töö orienteeruv maht on 2-4 lk teksti ning ettekandele kulub orienteeruvalt 15 minutit grupi
kohta. Grupis võiks olla 2-3 inimest.

==Arvestuse kujunemine==

'''Arvestuse''' saamiseks peavad olema tehtud:
1) suuliselt kaitstud '''kolm''' (seitsmest) laborites tehtavast praktilisest ülesandest
2) päevaõpe: kantud ette grupitööna valminud iseseisev töö (juhtumiuuring).
2) kaugõpe: kantud ette individuaaltööna valminud ettekanne või viki artikkel ainet puudutaval teemal

'''Boonuspunkte''' saab:

1) Teistele teema kohta ettekande tegemise eest (kogemuse jagamine)
2) Huvitavate praktikumi ülesannete välja mõtlemise eest
3) Praktikumis, õppejõuga kokkuleppel, kaastudengite juhendamise eest

Tudeng oskab juhtumiuuringus esitatud probleemi lahendada ja saadud
tulemusi ning järeldusi põhjendada.

Lävend:
Tudengi tehtud iseseisva töö juhtumiuuringus pakutud lahendus on
kirjeldatud teemakohaste terminitega ja lahendab tegeliku probleemi
korrektselt.

'''Õpiväljund3''':
Tudeng oskab rakendada vähemalt ühte andmesalvestustehnoloogiat.

Lävend:
Tudengi valitud andmesalvestustehnoloogia (nt RAID) on kasutatav andmete
salvestamiseks pärast seadistamiseks vajalike käskude sisestamist.

'''Õpiväljund4''':
Tudeng teab ja oskab rakendada varundamisvõtteid loodavale või juba
olemasolevale süsteemile.

termineid õiges kontekstis.

==Kodutööde/Iseseisvate tööde info==

Iseseisev töö toimub grupitöö vormis.Tudengid uurivad elulistel olukordadel põhinevaid juhtumeid ning pakuvad neile omalt poolt aine käigus omandatud teadmiste põhjal lahendusi. Uurimisele kuuluvad juhtumid on õppejõu poolt (edastatakse grupijuhi meilile). Iseseisva töö tulemusena valmib lühikokkuvõte probleemist, selle olemusest ning pakutud lahendusest, mis omakorda kantakse kaastudengitele suuliselt ette.
Töö orienteeruv maht on 2-4 lk teksti ning ettekandele kulub orienteeruvalt 15 minutit grupi
kohta. Grupis võiks olla 2-3 inimest.

==Arvestuse kujunemine==

'''Arvestuse''' saamiseks peavad olema tehtud:
1) suuliselt kaitstud '''kolm''' (seitsmest) laborites tehtavast praktilisest ülesandest
2) päevaõpe: kantud ette grupitööna valminud iseseisev töö (juhtumiuuring).
2) kaugõpe: kantud ette individuaaltööna valminud ettekanne või viki artikkel ainet puudutaval teemal

'''Boonuspunkte''' saab:

1) Teistele teema kohta ettekande tegemise eest (kogemuse jagamine)
2) Huvitavate praktikumi ülesannete välja mõtlemise eest
3) Praktikumis, õppejõuga kokkuleppel, kaastudengite juhendamise eest
4) LUGil ettekande tegemise eest

==Kodutööde/Iseseisvate tööde info==

Iseseisev töö toimub grupitöö vormis.Tudengid uurivad elulistel olukordadel põhinevaid juhtumeid ning pakuvad neile omalt poolt aine käigus omandatud teadmiste põhjal lahendusi. Uurimisele kuuluvad juhtumid on õppejõu poolt (edastatakse grupijuhi meilile). Iseseisva töö tulemusena valmib lühikokkuvõte probleemist, selle olemusest ning pakutud lahendusest, mis omakorda kantakse kaastudengitele suuliselt ette.
Töö orienteeruv maht on 2-4 lk teksti ning ettekandele kulub orienteeruvalt 15 minutit grupi
kohta. Grupis võiks olla 2-3 inimest.

==Arvestuse kujunemine==

'''Arvestuse''' saamiseks peavad olema tehtud:
1) suuliselt kaitstud '''kolm''' (seitsmest) laborites tehtavast praktilisest ülesandest
2) päevaõpe: kantud ette grupitööna valminud iseseisev töö (juhtumiuuring).
2) kaugõpe: kantud ette individuaaltööna valminud ettekanne või viki artikkel ainet puudutaval teemal

'''Boonuspunkte''' saab:

1) Teistele teema kohta ettekande tegemise eest (kogemuse jagamine)
2) Huvitavate praktikumi ülesannete välja mõtlemise eest
3) Praktikumis, õppejõuga kokkuleppel, kaastudengite juhendamise eest
4) LUGil ettekande tegemise eest

==Kodutööde/Iseseisvate tööde info==

Iseseisev töö toimub grupitöö vormis.Tudengid uurivad elulistel olukordadel põhinevaid juhtumeid ning pakuvad neile omalt poolt aine käigus omandatud teadmiste põhjal lahendusi. Uurimisele kuuluvad juhtumid on õppejõu poolt (edastatakse grupijuhi meilile). Iseseisva töö tulemusena valmib lühikokkuvõte probleemist, selle olemusest ning pakutud lahendusest, mis omakorda kantakse kaastudengitele suuliselt ette.
Töö orienteeruv maht on 2-4 lk teksti ning ettekandele kulub orienteeruvalt 15 minutit grupi
kohta. Grupis võiks olla 2-3 inimest.

2) Modify the march folder owner so that it will be student and the new group audio.

3) Modify the march folder's and its subfolders so that the user can do anything, group can do ls in the folder and cd into it and others can't do anything with it.

4) Create a hard link called network to a file /etc/network/interfaces

==Lab 1==

3 points - '''Managing users''' (adduser, addgroup, passwd, /etc/passwd, /etc/shadow)

1) Create a user noodle

2) Add a new group food and add a the user noodle to a group called food.

3) Divert the user noodle's password hash via cowsay to a file called cownoodle.txt.

4) Lock the user noodle and be ready to show me the indication of the user being locked.

5) Change the user's current home directory into /home/unknown so that the files will also be moved to the new location.

1) Create a folder march in root user directory and for every march day a subfolder with a name day1, day2, day3 … day31. (Example: /root/march/day1 or /root/march/day2 etc)

2) Modify the march folder owner so that it will be student and the new group audio.

3) Modify the march folder's and its subfolders so that the user can do anything, group can do ls in the folder and cd into it and others can't do anything with it.

4) Create a hard link called network to a file /etc/network/interfaces

5) Copy /var/log directory into march folder so that the timestamp and user info will be preserved.

3) Send 2 htop's to the background and be ready to present how you send a kill signal to the first htop by job number and term signal to the second htop by a process number.

4) Create an alias called bye that logs you out of the terminal. Make this alias permanent.

5) Execute a programm called espdiff and diver the standardoutput to a file called okay.txt and the standard error to a file called notokay.txt.

We will not have a lecture in the ordinary sense, instead we'll have a seminar or discussion on important aspects of working in IT. The ethical, social and personal aspects of it. Terms like "imposter syndrome", burnout, teamwork and better work environment will be some of the topics covered. Life is not only technical competence, it's a lot about human interaction as well.

=Lab works=

==Lab 0==

Installing Ubuntu Server 14.04.3 LTS

'''Introduction to Unix command line''' (cd, ls, cat, full path, relative path etc)

==Lab 1==

3 points - '''Managing users''' (adduser, addgroup, passwd, /etc/passwd, /etc/shadow)

1) Create a user noodle

2) Add a new group food and add a the user noodle to a group called food.

3) Divert the user noodle's password hash via cowsay to a file called cownoodle.txt.

4) Lock the user noodle and be ready to show me the indication of the user being locked.

5) Change the user's current home directory into /home/unknown so that the files will also be moved to the new location.

5 points - '''Managing files''' (mkdir, cp, mv, rm, touch, nano, less, chmod, chown, rwx, 644 etc)

1) Create a folder march in root user directory and for every march day a subfolder with a name day1, day2, day3 … day31. (Example: /root/march/day1 or /root/march/day2 etc)

2) Modify the march folder owner so that it will be student and the new group audio.

3) Modify the march folder's and its subfolders so that the user can do anything, group can do ls in the folder and cd into it and others can't do anything with it.

4) Create a hard link called network to a file /etc/network/interfaces

5) Copy /var/log directory into march folder so that the timestamp and user info will be preserved.

4 points - '''Processes and environment variables''' (kill, using directing input/output/error: |, <, >, >>; env, PATH, HOME etc)

1) Divert the list with the student user's groups via cowsay into a fail studgroup.txt.

2) Create a environment variable called MYHOME that has the value of the system's HOME environment variable. (Hint: you have tu use variable symbol here!)

3) Send 2 htop's to the background and be ready to present how you send a kill signal to the first htop by job number and term signal to the second htop by a process number.

4) Create an alias called bye that logs you out of the terminal. Make this alias permanent.

5) Execute a programm called espdiff and diver the standardoutput to a file called okay.txt and the standard error to a file called notokay.txt.

==Lab 1==

3 points - '''Managing users''' (adduser, addgroup, passwd, /etc/passwd, /etc/shadow)

1) Create a user noodle

2) Add a new group food and add a the user noodle to a group called food.

3) Divert the user noodle's password hash via cowsay to a file called cownoodle.txt.

4) Lock the user noodle and be ready to show me the indication of the user being locked.

5) Change the user's current home directory into /home/unknown so that the files will also be moved to the new location.

1) Create a folder march in root user directory and for every march day a subfolder with a name day1, day2, day3 … day31. (Example: /root/march/day1 or /root/march/day2 etc)

2) Modify the march folder owner so that it will be student and the new group audio.

3) Modify the march folder's and its subfolders so that the user can do anything, group can do ls in the folder and cd into it and others can't do anything with it.

4) Create a hard link called network to a file /etc/network/interfaces

1) Create a folder march in root user directory and for every march day a subfolder with a name day1, day2, day3 … day31. (Example: /root/march/day1 or /root/march/day2 etc)

2) Modify the march folder owner so that it will be student and the new group audio.

3) Modify the march folder's and its subfolders so that the user can do anything, group can do ls in the folder and cd into it and others can't do anything with it.

4) Create a hard link called network to a file /etc/network/interfaces

5) Copy /var/log directory into march folder so that the timestamp and user info will be preserved.

4 points - '''Processes and environment variables''' (kill, using directing input/output/error: |, <, >, >>; env, PATH, HOME etc)

1) Divert the list with the student user's groups via cowsay into a fail studgroup.txt.

2) Create a environment variable called MYHOME that has the value of the system's HOME environment variable. (Hint: you have tu use variable symbol here!)

3) Send 2 htop's to the background and be ready to present how you send a kill signal to the first htop by job number and term signal to the second htop by a process number.

4) Create an alias called bye that logs you out of the terminal. Make this alias permanent.

5) Execute a programm called espdiff and diver the standardoutput to a file called okay.txt and the standard error to a file called notokay.txt.

==Lab 1==

3 points - '''Managing users''' (adduser, addgroup, passwd, /etc/passwd, /etc/shadow)

1) Create a user noodle

2) Add a new group food and add a the user noodle to a group called food.

3) Divert the user noodle's password hash via cowsay to a file called cownoodle.txt.

4) Lock the user noodle and be ready to show me the indication of the user being locked.

5) Change the user's current home directory into /home/unknown so that the files will also be moved to the new location.

5 points - '''Managing files''' (mkdir, cp, mv, rm, touch, nano, less, chmod, chown, rwx, 644 etc)

1) Create a folder march in root user directory and for every march day a subfolder with a name day1, day2, day3 … day31. (Example: /root/march/day1 or /root/march/day2 etc)

2) Modify the march folder owner so that it will be student and the new group audio.

3) Modify the march folder's and its subfolders so that the user can do anything, group can do ls in the folder and cd into it and others can't do anything with it.

4) Create a hard link called network to a file /etc/network/interfaces

5) Copy /var/log directory into march folder so that the timestamp and user info will be preserved.
