There is no apache process running, and AOLserver
is indeed able to bind to port 80, as shown by the
error log (although I don't know what a return value
of 15 from the binder means). I've tried port 8000
also, with the same result. So it is AOLserver
that is returning the empty page. I strongly suspect
that the empty page is coming from somewhere within
OpenACS, because when I searched for the string that
is in the header of the source of the empty page,
it produced lots of matches in the OpenACS tree. Of
course, some other process could be using the identical
header string, but it is unlikely that it would be
able to respond to a request to port 80.
Also, I was initially using Postgres 7.3.2, and have
now tried 7.2.3 (had to recompile AOLserver), but
with the same result.
When I try to connect to the server from the command
line by telnetting to port 80, I don't get the usual
(empty) prompt, where the server waits for me to enter
a GET request. Instead, the server throws
me an error right away:
$ telnet 18.42.2.64 80
Trying 18.42.2.64...
Connected to 18.42.2.64.

Don't know if this helps.
Thanks!
