[Tutor] apache python cgi sockets error 13 (resend after joining the tutorial list)

Thu May 7 12:56:53 CEST 2015

Hi I have tried Python TCPIP sockets and Unix sockets processed in a python cgi script, called from apache under fedora19. In both cases a permissions error is returned at sock.connect(). I have tried changing permissions x and r w on ALL of user, group, other to no avail. In both cases the cgi script runs if directly executed from /var/www/cgi-bin with no apache involvement.

  In both cases all the other (non sockets())  python cgi scripting works in the apache server environment. 

  I note I needed to enable http in the ferora19 firewall to have the apache server work from locahost or from another device connected to the router. Please find the myUnix2.cgi socket script below. Help appreciated! Regards,              Stewart Lawton
