1.1       albertel    1: 	
                      2: 	   Setting Up CAPA v. 5.1 For First Time Users:
                      3: 
                      4: 
                      5: --------------------------------------------------------------------------------
                      6: 
                      7: READ ALL INSTRUCTIONS BEFORE PRECEDING WITH THE INSTALLATION.
                      8: 
                      9: Please go to http://capa.msu.edu/mailman and subscribe to the CAPA Announce 
                     10: email list.  Anyone interested in receiving CAPA updates and announcements 
                     11: can add himself or herself to the list.  Please notify all instructors and 
                     12: technical staff that will work with CAPA about adding themselves to the list.
                     13: 
                     14: The following installation instructions assume that whoever is installing 
                     15: the CAPA system already has some knowledge of their operating system and 
                     16: is familiar with Unix commands such as the following: cd, chown, chmod and 
                     17: setting permissions, compress/uncompress, cp, ln, lpr, ls, mkdir, pwd, rm, 
                     18: su, tar, and the vi editor.  
                     19: 
                     20: In order to complete the installation, you will need to have Perl, 
                     21: Ghostscript, TeTex, and a webserver (e.g. Apache) installed on your machine 
                     22: (all of which can be obtained for free).  You should know where those 
                     23: applications are located and where the web server's configuration files are 
                     24: located (particularly srm.conf).  You should also be familiar with killing 
                     25: and restarting your web daemon.
                     26: 
                     27: You will notice lists of files in these instructions to compare your
                     28: permissions with.  Depending on your operating system, many of your file 
                     29: sizes may differ with the ones given in these instructions.  Please do
                     30: not be concerned by this.
                     31: 
                     32: --------------------------------------------------------------------------------
                     33: 
                     34: INITIAL SETUP
                     35: 
                     36: 1.)  Create the user "teacher" with group membership "cai".  If you are 
                     37: unfamiliar with adding new users and groups to your system, then use the 
                     38: instructions below.  
                     39: 
                     40: Adding new users can be accomplished in one of two ways.  Both require you to 
                     41: login as root first.
                     42: 
                     43: 	a.)  Most systems have an "adduser" utility of one form or
                     44: another, normally located in the directory /usr/sbin.  To use this
                     45: utility, login as root, cd to /usr/sbin and enter the command
                     46: "adduser" (or "useradd" depending on your system).  You will be prompted 
                     47: for information regarding the user. For Solaris and Digital Unix, you 
                     48: will be asked to specify the user name (teacher), the UID (normally 
                     49: the default value), the full name (enter what you like here), the 
                     50: login group (we use "cai" which stands for Computer Aided Instruction), 
                     51: a secondary group (we usually leave this blank), a parent directory 
                     52: (depends upon your system), a login shell (this is a preference item, 
                     53: here we use /bin/tcsh), and an initial password.  If you are asked if 
                     54: you want to edit an authority file, etc., answer no.
                     55: 
                     56: The Linux adduser utility requires you to enter the command as 
                     57: "adduser teacher" or "useradd teacher".  This utility automatically 
                     58: creates the directories and groups.  The Debian version prompts 
                     59: the administrator for the full name, office number, phone number, 
                     60: etc.  You may choose to enter only the full name and leave the 
                     61: other information blank.  If you wish to have something other than 
                     62: the Bourne-Again SHell as the login shell, you will need to manually 
                     63: edit the /etc/passwd file once you have created the user.  You will 
                     64: also need to manually change the group ID number for teacher to have 
                     65: group membership "cai" using the vipw command.  Then use the command 
                     66: "chgrp -R" or "chown -R" to recursively change the group membership 
                     67: of the "teacher" home directory.
                     68: 
                     69: NOTE: In most cases you will be asked if you want to add the new group 
                     70: "cai" when you specify it for the new user "teacher".  Otherwise, if you 
                     71: want to use the group "cai" you will have to create it using "addgroup" 
                     72: (or "groupadd" for some systems).
                     73: 
                     74: 	b.)  For all systems, you can manually add users by creating
                     75: an entry in the /etc/passwd file in the correct format using the vipw
                     76: command.  Consult entries already present in /etc/passwd or a book on Unix 
                     77: system administration if you are going to manually create your users. If you 
                     78: manually add your users, you will also need to make the appropriate 
                     79: entries in /etc/group and manually create the home directory for the user.
                     80: 
                     81: 2.)  Login as teacher and create a directory under the teacher account
                     82: called CAPA51.  This directory should now be owned by "teacher" and have
                     83: group membership "cai".
                     84: 
                     85: drwxr-xr-x    6 teacher  cai          1024 Jul 17 14:03 CAPA51
                     86: 
                     87: --------------------------------------------------------------------------------
                     88: 
                     89: SETTING UP THE INSTRUCTOR INTERFACE AND OPTIONAL TELNET STUDENT INTERFACE
                     90: 
                     91: You have the option to install the telnet version of the CAPA interface.
                     92: It responds much quicker than the web, especially with a slow modem.  If 
                     93: you decide not to enable this feature then skip steps 5 and 6.
                     94: 
                     95: Please note that in the following instructions, it is assumed that the 
                     96: teacher directory is in /home.  This may not be the case with your machine 
                     97: (e.g. /usr/users, /home2, etc.).  You may want to make note of this as you 
                     98: read through these instructions prior to installation.
                     99: 
                    100: 1.)  Become root and copy or move the DIST51 directory to the teacher home 
                    101: directory.  Recursively change the ownership of the DIST51 directory to 
                    102: teacher with group membership cai.
                    103: 
                    104: >chown -R teacher:cai DIST51  
                    105: 
                    106: 2.)  We first need to link up the binaries to use the instructor 
                    107: interface of CAPA.  Login as root.  Change directory to /usr/local/bin 
                    108: (or /usr/bin, or whatever will be the default in your users "path").
                    109: Symbolically link the binaries contained with the distribution by
                    110: entering the commands:
                    111: 
                    112: > cd /usr/local/bin
                    113: > ln -s /home/teacher/DIST51/LinkToBin/quizzer .
                    114: > ln -s /home/teacher/DIST51/LinkToBin/grader .
                    115: > ln -s /home/teacher/DIST51/LinkToBin/manager .
                    116: > ln -s /home/teacher/DIST51/LinkToBin/qzparse .
                    117: > ln -s /home/teacher/DIST51/LinkToBin/allcapaid .
                    118: > ln -s /home/teacher/DIST51/LinkToBin/answers .
                    119: 
                    120: 3.)  Check that all of the binaries in /home/teacher/DIST51/LinkToBin 
                    121: have executable permissions as shown below:
                    122: 
                    123: >cd /home teacher/DIST51/LinkToBin
                    124: >ls -l
                    125: -rwxr-xr-x    1 teacher  cai        485095 Jul 17 14:35 allcapaid
                    126: -rwxr-xr-x    1 teacher  cai        505454 Jul 17 14:35 answers
                    127: -rwxr-xr-x    1 teacher  cai       2126685 Jul 17 14:35 grader
                    128: -rwxr-xr-x    1 teacher  cai       2267429 Jul 17 14:35 manager
                    129: -rwxr-xr-x    1 teacher  cai       2191991 Jul 17 14:35 quizzer
                    130: -rwxr-xr-x    1 teacher  cai        488366 Jul 17 14:35 qzparse
                    131: 
                    132: 4.)  Now link up the demonstration library in the root directory.  To do this, 
                    133: login as root, change to the root directory (cd /) and enter: 
                    134: 
                    135: > ln -s /home/teacher/DIST51/demolibrary demolibrary
                    136: 
                    137: Check that the demolibrary in the DIST51 folder is owned by "teacher" and 
                    138: has group membership "cai".
                    139: 
                    140: 5.)  *SKIP THIS STEP IF YOU ARE NOT ENABLING THE TELNET INTERFACE*
                    141: Login as "teacher" and copy the file "capalogin" from the directory 
                    142: DIST51/PutInCAPA51 into the directory /home/teacher/CAPA51.  Check 
                    143: to make sure your permissions match the following: 
                    144: 
                    145: -rwsr-xr-x    1 teacher  cai        585097 Jul 17 15:03 capalogin
                    146: 
                    147: Make certain that capalogin is set UID mode (there is an "s" instead
                    148: of an "x" in the user's permissions).  If not enter the following:
                    149: 
                    150: > chmod u+s capalogin
                    151: 
                    152: 6.)  *SKIP THIS STEP IF YOU ARE NOT ENABLING THE TELNET INTERFACE*
                    153: For each class that telnet is enabled for, it is added as a user
                    154: to the system without a password.  The security of the system is
1.2     ! albertel  155: maintained by using capalogin as the login shell.  To set up the
        !           156: demonstration class, become root then use the adduser utility to create the
1.1       albertel  157: user "nsc131s0".  Enter the group id the same as the instructor (cai), the
1.2     ! albertel  158: home directory to be /home/teacher/CAPA51/nsc131s0, and the login shell
        !           159: to be /home/teacher/CAPA51/capalogin.  When you are prompted to
        !           160: enter an initial password, hit return.  You then need to edit the
        !           161: /etc/passwd file with the vipw command to remove the "Nologin" field.
        !           162: (You may also need to edit the file /etc/shadow if your system uses
        !           163: shadow passwords.)
1.1       albertel  164: 
                    165: For Linux systems, you will need to create the user, edit /etc/passwd 
1.2     ! albertel  166: to remove the password field, change the group id number, change the home
        !           167: directory and change the login shell.  You will not be prompted for these
        !           168: within the utility.  Make certain the group id number is the same as the
1.1       albertel  169: instructor account.  Editing the passwd file is done by becoming root
1.2     ! albertel  170: using the vipw command.  (You may also need to edit the file /etc/shadow
        !           171: if your system uses shadow passwords.)  Finally, you must delete the
        !           172: directory created by the adduser utility, for example:
1.1       albertel  173: 
1.2     ! albertel  174: >rm -rf /home/nsc131s0
1.1       albertel  175: 
1.2     ! albertel  176: Depending on your system, you may not be allowed to add a user without a
1.1       albertel  177: password using the adduser utility.  If this is the case, you will need
                    178: to manually add the user with the vipw command.
                    179: 
                    180: Repeat the steps above for qns131s0 and xpc131s0 (do not add xns131s0 as
                    181: a user).
                    182: 
1.2     ! albertel  183: The correct class entries in /etc/passwd are given below: (The paths to the
1.1       albertel  184: home directory and login shell may differ for your system.)
                    185: 
1.2     ! albertel  186: nsc131s0::1004:103:Demonstration Class - Homework:/home/teacher/CAPA51/nsc131s0:
        !           187: /home/teacher/CAPA51/capalogin
        !           188: qns131s0::1005:103:Demonstration Class - Quizzes:/home/teacher/CAPA51/qsc131s0:/
        !           189: home/teacher/CAPA51/capalogin
        !           190: xpc131s0::1006:103:Demonstration Class - Exam Partial Credit:/home/teacher/CAPA5
        !           191: 1/xpc131s0:/home/teacher/CAPA51/capalogin
1.1       albertel  192: 
                    193: 7.)  Login as teacher and create the class called nsc131s0 in teacher's
                    194: CAPA51 directory.
                    195: 
                    196: > cd CAPA51
                    197: > cp -R /home/teacher/DIST51/PutInCAPA51/nsc131s0 nsc131s0
                    198: 
                    199: Then, check to be certain the owner of the nsc131s0 directory is "teacher" 
                    200: with group membership "cai".
                    201: 
                    202: Repeat this step using the qns131s0, xns131s0, and xpc131s0 directories.
                    203: 
                    204: 8.)  Make certain a directory named "records" exists in each of the class 
                    205: directories (e.g. /home/teacher/CAPA51/nsc131s0/records). Also, make certain the

                    372: 
                    373: Do this for all three lines.
                    374: 
                    375: 8.)  Check to be certain there is a directory 
                    376: /home/teacher/PublicWeb/CAPA/capa-bin/teacher.  Make certain the files 
                    377: capasbin and capadiscuss are located there, owned by teacher, and a 
                    378: member of the cai group.  Also, double check that the capasbin file 
                    379: has executable, set UID permission (there is an "s" instead of an "x"
                    380: in the user's permissions).  Example:
                    381: 
                    382: -rwxr-xr-x    1 teacher  cai         23453 Jul 17 15:51 capadiscuss
                    383: -rwsr-xr-x    1 teacher  cai        519680 Jul 17 15:51 capasbin
                    384: 
                    385: If not, then enter:
                    386: > chmod u+s capasbin
                    387: 
                    388: (NOTE:  Do not be alarmed if you see the CAPA generated web_access.log
                    389:  file in this directory also.)
                    390: 
                    391: 9.)  Double check ownership and permissions in the PublicWeb directory again.
                    392: 
                    393: 10.)  Create a directory under teacher called Public.  Change directories
                    394: into the new Public directory and create another directory name demolibrary.  
                    395: In Public/demolibrary/ create symbolic links to the Graphics and Links 
                    396: directories:
                    397: 
                    398: > cd /home/teacher/Public/demolibrary 
                    399: > ln -s /demolibrary/Graphics Graphics
                    400: > ln -s /demolibrary/Links Links
                    401: 
                    402: 11.) When finished you should have the following directory structure:
                    403: 
                    404: > pwd
                    405: /home/teacher/Public
                    406: > ls -l
                    407: total 1

                    414: 
                    415: 12.) Login as root, find the srm.conf file of your web server and edit this
                    416: file by making the following changes:
                    417: 
                    418: 	a.) Add the following lines:
                    419: 
                    420: 	Redirect /CAPA/index.html   http://your.machine/capa-bin/class.html
                    421: 	Redirect /CAPA/class.html   http://your.machine/capa-bin/class.html

                    423: 	Redirect /CAPA/emailid.html http://your.machine/capa-bin/emailid.html
                    424: 
                    425: 	Alias /CAPA/   /home/teacher/PublicWeb/CAPA/
                    426: 	Alias /demolibrary/   /home/teacher/Public/demolibrary/
                    427: 
                    428: 	ScriptAlias /capa-bin/  /home/teacher/PublicWeb/CAPA/capa-bin/
                    429: 
                    430: 	Do not be concerned if you webserver's comments suggest using another
                    431: 	file and leaving the srm.conf file blank.
                    432: 
                    433: 	b.)  If your machine is dedicated only to CAPA, you may choose to 
                    434: 	add the following lines to the srm.conf file also: 
                    435: 
                    436: 	ErrorDocument 403 /capa-bin/class.html
                    437:  	ErrorDocument 404 /capa-bin/class.html
                    438: 
                    439: 	This way invalid and forbidden URL's are redirected back to the 
                    440: 	class.html page instead of receiving an error message.  This will
                    441: 	also allow one to enter just the machine name for the URL and get
                    442: 	to the web login page.
                    443: 
                    444: 	c.)  If your machine is dedicated only to CAPA, you may want to 
                    445: 	change the following line:
                    446: 	DocumentRoot /some/other/document/root
                    447: 	     to the following:
                    448: 	Document Root /home/teacher/PublicWeb/CAPA
                    449: 	Make sure to change the document root in other configuration files,
                    450: 	such as httpd.conf and access.conf, if you plan to do this.  This 
                    451: 	line might only be located in the httpd.conf file.  Carefully search
                    452: 	through the webserver's configuration files and change any lines which
                    453: 	have directory names that should match the DocumentRoot.  THE COMMENTS
                    454: 	IN THE CONFIGURATION FILES WILL CLEARLY STATE IF SUCH A CHANGE IS TO
                    455: 	BE MADE.
                    456: 
                    457: 13.)  If the webserver is not owned by teacher, make sure the owner of the 
                    458: webserver can write to the capa-bin directory.  One way of doing this is to 
                    459: make the capa-bin directory group writable and give the owner of the webserver 
                    460: membership in the group "cai".
                    461: 
                    462: 14.)  Kill and restart your web daemon.
                    463: 
                    464: 
                    465: 15.) Students will now be able to access the capa homework via telnet to  
                    466: your.machine.name and via netscape at the URL:
                    467:

                    474: 
                    475:    and if you opted to add the change in step 12b:
                    476: http://your.machine.name
                    477: 
                    478: Students can get a CAPAID with a CAPA ID from a previous problem set
                    479: at http://your.machine.name/capa-bin/getid.html
                    480: or http://your.machine.name/CAPA/getid.html
                    481: 
                    482: Students can also have a CAPAID emailed to them without a previous ID from
                    483: http://your.machine.name/capa-bin/emailid.html 
                    484: or http://your.machine.name/CAPA/emailid.html
                    485: without a previous CAPA ID.

                    489: FINAL INSTRUCTIONS
                    490: 
                    491: 1.)  Modify /demolibrary/Tools/StdMacros
                    492: 
                    493: Replace the line
                    494: /LET machine_name="capa2.nscl.msu.edu"  // needed for labeling tools
                    495: With
                    496: /LET machine_name="your.machine.name"  // needed for labeling tools
                    497: 
                    498: 2.)  Double check to be certain the ownership and group membership 
                    499: for each of the files and subdirectories under the teacher account 
                    500: consistently have "teacher" as owner and "cai" as group.  Also double
                    501: check that the demolibrary directory in /home/teacher/DIST51 is owned
                    502: by "teacher" and has group membership "cai".
                    503: 
                    504: 3.)  Make sure that the user teacher, the owner of the webserver, and
                    505: root have the commands allcapaid, perl and gs (ghostscript command) in 
                    506: their path.  You can check this by using the which command.  If it is
                    507: in the user's path, you will then be shown where the directory for the
                    508: command is located.  
                    509: For example:
                    510: 
                    511: > which perl
                    512: /usr/bin/perl
                    513: 
                    514: 4.)  If teacher is somewhere other than /home, then you need to edit the 
                    515: capa.config files in the nsc131s0, qns131s0, xns131s0, and xpc131s0 directories.
                    516: Change the following lines to refer to the correct path:
                    517: 
                    518: quiz_path       = /home/teacher/CAPA51/qns131s0
                    519: exam_path       = /home/teacher/CAPA51/xns131s0
                    520: supp_path       = /home/teacher/CAPA51/xpc131s0
                    521: .
                    522: .
                    523: .
                    524: correction_path = /home/teacher/CAPA51/xpc131s0
                    525: 
                    526: 5.)  In each of the capa.config files (DIST51/PutInCAPA51/nsc131s0/capa.config,
                    527: ..., ...skeleton/capa.config, etc. and /home/teacher/CAPA51/nsc131s0, etc.) edit 
                    528: the print commands to match the ones that you use from your server where CAPA is 
                    529: installed.  The comments in the printing configuration section of the capa.config 
                    530: file will direct you how to make these changes.
                    531: 
                    532: Also, edit the line:
                    533: 
                    534: capa_server = your.machine.name
                    535: 
                    536: In the "Extrapolate Scores Applet" section to read the name of your capa server
                    537: in each of the capa.config files.
                    538: 
                    539: 6.)  Print the Manual.  
                    540: 
                    541: 7.)  Take a look at the sets in nsc131s0. In particular sets 3-17 (a
                    542: detailed list of the templates).
                    543: 
                    544: 8.)  Read the READMEsecurity.txt file.

                    564: 
                    565: ADDING ADDITIONAL USERS
                    566: 
                    567: 1.)  Add the new user to your system with group membership cai.  If you are
                    568: unsure about doing this, follow the same instructions outlined in the 
                    569: "INITIAL SETUP" section except use the new user's name instead of "teacher" 
                    570: (and the new group's name if the new instructor to be added to the CAPA system 
                    571: should be in a different group other than "cai").
                    572: 
                    573: 2.)  Login as root and add a directory to the capa-bin directory with the same 
                    574: name as the new instructor's user name.  For example:
                    575: > mkdir /home/teacher/PublicWeb/CAPA/capa-bin/instructor-name
                    576: 
                    577: 3.)  Copy the files capasbin and capadiscuss from 
                    578: teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/teacher into the new
                    579: instructor-name directory.  For example:
                    580: 
                    581: > cd /home/teacher/PublicWeb/CAPA/capa-bin/instructor-name
1.2     ! albertel  582: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/teacher/capasbin .
        !           583: > cp /home/teacher/DIST51/CopyToPublicWeb/CAPA/capa-bin/teacher/capadiscuss .
1.1       albertel  584: 
                    585: Make sure that the permissions for the the capasbin and capadiscuss files 
                    586: are executable and that capasbin is set UID mode (there is an "s" instead

                    706: 
                    707: 2.)  Make certain a copy of capa.config exists in the "classname"
                    708: directory.  Also double check the ownership and group membership of
                    709: the classname file and all of its sub-directories and files have the
                    710: appropriate owner and group membership.
                    711:
