Question

I've installed twiki, but it's not happy.

http://netebb.com/twiki/bin/testenv reports all is well, but

http://netebb.com/twiki/bin/view gives a Internal Server Error:

[Mon Nov 12 01:50:12 2001] [error] (13)Permission denied: exec of /home/www/twiki/bin/view failed
[Mon Nov 12 01:50:12 2001] [error] [client 192.168.1.2] Premature end of script headers: /home/www/twiki/bin/view

If I copy view to view.cgi, the problem goes away. See http://netebb.com/twiki/bin/view.cgi.

I took my httpd.conf changes straight from http://twiki.org/cgi-bin/view/TWiki/TWikiDocumentation#Step_1_Create_amp_Configure_the_

ScriptAlias /twiki/bin/ "/home/www/twiki/bin/"
Alias /twiki/ "/home/www/twiki/"
<Directory "/home/www/twiki/bin">
   Options +ExecCGI
   SetHandler cgi-script
   Allow from all
</Directory>
<Directory "/home/www/twiki/pub">
   Options FollowSymLinks +Includes
   AllowOverride None
   Allow from all
</Directory>
<Directory "/home/www/twiki/data">
   deny from all
</Directory>
<Directory "/home/www/twiki/templates">
   deny from all
</Directory>

I'm stumped. I've surfed around for an answer, but it doesn't seem anyone else has encountered this problem before.

Any help would be greatly appreciated.

Thanks,

Ross Smith

Answer

You may have already checked this, but you do need to make sure that view has executable permissions under Linux - e.g. chmod +x the file. If you copied view.cgi to view, this could have reset the perms.

Dang. That was it! Silly me. I wish Apache's error messages were more descriptive! Thanks for pointing me in the obvious direction.

Thanks -- I made the same mistake. Irritating how the mind will sometimes filter out the proper and obvious path for the unknown. I.E. "It can't be permissions... It must be that TWiki is reacting badly to how I configured mod-perl! Or perhaps TWiki doesn't work with Apache2! -- JoshuaMorast - 04 Oct 2002

At least in this case, the Apache errors are quite information - 'permission denied' means that the Unix permissions didn't allow the file to be executed.
