I tried to incorporate suggestions I've received. After restarting apache2,
this is what happened:
tomkane@sfq:~$ /etc/init.d/apache2 start
* Starting web server apache2
[Tue May 17 20:12:34 2011] [warn] module perl_module is already loaded, skipping
(13)Permission denied: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
[fail
Now apache2 won't even start. It's not as if my network address is gone because
I see it's still there at boot time. I'm going a little daft now. It's not as
if I haven't seen a message like this before, but I've forgotten what to do
about it. Any suggestions?
Once again, I want to thank everyone for their suggestions.
Tom
