| 45 : | <ul> | ||
| 46 : | <li> guess what went wrong and try to fix it. | ||
| 47 : | <li> call the offending script directly from the command line | ||
| 48 : | of unix | ||
| 49 : | <li> enable the debugging features by redefining | ||
| 50 : | \$cgiURL in Global.pm and checking the redirection scripts in | ||
| 51 : | system/cgi. This will force the standard error to be placed | ||
| 52 : | in the standard out pipe as well. | ||
| 53 : | <li> Run tail -f error_log <br> | ||
| 54 : | from the unix command line to see error messages from the webserver. | ||
| 55 : | The standard error output is being placed in the error_log file for the apache | ||
| 56 : | web server. To run this command you have to be in the directory containing the | ||
| 57 : | error_log or enter the full path name of the error_log. <p> | ||
| 58 : | In a standard apache installation, this file is at /usr/local/apache/logs/error_log<p> | ||

| 125 : | ## IMPORTANT: The items in the section below: | ||
| 126 : | ## "##These will most likely need to be customized for your site" | ||
| 127 : | ## should be customized for your own site. | ||
| 128 : | |||
| 129 : | |||
| 130 : | ## The variables defined in this package set defaults and | ||
| 131 : | ## parameters for the whole weBWorK system. Defaults can | ||
| 132 : | ## be over ridden for individual courses by redefining | ||
| 133 : | ## variables in the individual course webworkCourse.ph file. | ||
| 134 : | ## For example the default SYSTEM feedback address set below as: | ||
| 135 : | ## $feedbackAddress = 'webwork@math.rochester.edu'; | ||
| 136 : | ## can (and should) be over ridden for an individual course by entering e.g. | ||
| 137 : | ## $Global::feedbackAdress = 'apizer@math.rochester.edu, gage@math.rochester.edu'; | ||
| 138 : | ## in the individual course webworkCourse.ph file. Of course you should really | ||
| 139 : | ## enter the email address(es) of the professors teaching the course. | ||
| 140 : | |||
| 141 : | ### Private vars - refer to these as $Global::var ### | ||
| 142 : | |||
| 143 : | ## These will need to be customized for your site | ||
| 144 : | |||
| 145 : | $feedbackAddress = 'webwork@math.rochester.edu'; ## please change | ||
| 146 : | #$legalAddress = '^\w+(\@(\w+.)*rochester\.edu)?$'; # destinations must match | ||
| 147 : | $legalAddress = '^[\w\-\.]+(\@([\w\-\.]+)*\.edu)?$'; # destinations must match | ||
| 148 : | $webmaster = 'webmaster'; | ||
| 149 : | $smtpServer = '127.0.0.1'; ## probably needs to be changed | ||
| 150 : | $dirDelim = '/'; | ||
| 151 : | |||
| 152 : | ## Change DBtie_file only if you want to change the default database. The script | ||
| 153 : | ## db_tie.pl uses DB_File (the Berkeley DB) and gdbm_tie.pl uses GDBM_File. This | ||
| 154 : | ## setting can be changed for an individual course in the webworkCourse.ph file. For | ||
| 155 : | ## some other database, you will have to write your own database tie-file. Such | ||
| 156 : | ## files reside in the scripts directory. | ||
| 157 : | |||
| 158 : | #$DBtie_file = 'db_tie.pl'; | ||
| 159 : | $DBtie_file = 'gdbm_tie.pl'; | ||
| 160 : | |||
| 161 : | ## Set to 1 to enable the access log; set to 0 to disable. | ||
| 162 : | ## | ||
| 163 : | ## The access log is stored in the logs/ directory under the system directory | ||
| 164 : | ## in a file called "access_log". It contains information about virtually | ||
| 165 : | ## every action committed by users, including all answers submitted. | ||
| 166 : | ## Usually this information is unneccessary, and the file becomes | ||
| 167 : | ## large very quickly, so this log is ordinarily turned off. However, the | ||
| 168 : | ## information it contains might be useful if, for example, a student wants an | ||
| 169 : | ## extension and claims not to have viewed the correct answers. | ||
