• From which hosts do you run pcmode command?
  

   MUST BE DONE from Host pcmode and by any TECH member

• To stop a reboot session in the last 5 minutes
  

      
       $ /xsys/pkg/pcmode/bin/pcmode -a hostname
        This will stop the login to the host and kill the job
        eg
        /xsys/pkg/pcmode/bin/pcmode -a jun05

• To check the status of a host

         /xsys/pkg/pcmode/bin/pcmode -c hostname

• What mode options are available

         labtest   linux   windows   default

• Put a host in labtest mode standalone

         eg1 /xsys/pkg/pcmode/bin/pcmode -t 0 -m labtest jun01
         eg2 /xsys/pkg/pcmode/bin/pcmode -t 0 -m default vr04 
 

• Student screen freezes and cannot move mouse when editing. How can you preserve student's data without having to reboot the host ?

  This process had been automated. When the students login into labtest mode 

they are given a choice as to whether they want to restore data or not? If they select “Yes”, the TA will sign in and restore their data from the host to be copied

You can use the keyboard [Ctrl-Alt-F1] option to log into the host via a terminal window. Do a 'ls -l' listing on the directory and see what file was last updated by the user. In the case of one student who was using nedit, we made a copy the file being worked on. Then terminate the nedit program. A 'ps -ef | grep -i nedit' command will display the nedit program pid .
Ctrl-Alt-F7 will position you back to the graphical interface the student was working on. Reopen the application “nedit” and open the copied file .

Alternatively, any tech member can ssh to the host the student is working on when in labtest mode and do the same as the above.

• Hosts does not revert back to default mode

  Check that the default file exists for that host..
  /cs/local/share/pcmode/default/hostname

• No access to labtest mode

Use ltenable to set the permissions right on a directory

  eg:  ltenable <full path to labtest directory>
  to do a manual check:
  group of labtest directory should be : LABTEST
  chmod 770 <labtest directory>

 
  To Disable the directory so other will not be able to get into it
  use **ltdisable**
      
      

• Check if submits from labtest are successful

    The /cs/course/<course-number>/submit directory must exist
     Permissions here should be 755 username:faculty directory submit
     Inside this directory , 
     Section of labtest name eg:
     labtest3
     Permissions should be
     770 .. owner - facultymember
            group - labtest

     Note : all students belong to group submit 

• at job does not run

The job id got duplicated because of restoring an old directory from

    the previous term and the id already existed
    The date may be scheduled wrong
    

• At the start of the semester

REMOVE all directories under pcmode/schedule

     If you return a directory , make sure the id's are deleted

• User cannot view his index.html file . Says there is none

    It turns out that the user set up the directory under
    /cs/course/xxxx/labtest when it SHOULD BE
    /cs/dept/www/course/xxxx/labtest

• Check is a user can login into labtest mode-Hint User Restriction-

   % /xsys/pkg/pcmode/bin/pcmode-allow cse1234 6 jun01 where 
      cse1234 is the user name
      6 is the job ID
      jun01 is the host being questioned
