We're getting closer to getting WeBWorK to work. When we try to login with a valid user from our classlist database we get the following message:

"Error: Key database error

Can't tie /Net/lunen/cis/www/oncampus/academics/mcs/webwork/system/courses/mcs121a/DATA/.auth/mcs121a_password_DB: Interrupted system call"

Any suggestions?

Hi Charles,

My first guess is that you haven't built the data base yet (does the database exist?, does it have permission 660?). The "Can't tie" message means the database can not be read. Look at e.g. the last few steps in item 24 of (building the demoCourse) assuming you have followed the steps up to that point. demoCourse demoCourse.lst
Now enter (using [Tab] completion): demoCourse apizer
You should see a listing of permissions with apizer having permission 10.

Another possibility is that the webserver is not in the group and so can not read the database or you haven't restarted the webserver after adding it to the group (see item 23 in ).

In general gives very detailed instructions which are very useful even for non linux systems.

Let me know if the above doesn't do the trick. I'll post your email and my response to
