Re: Open error

This is a failure to open a tcp-server-stream, it does
not indicate a problem with OPEN itself. I suggest you
test establishing TCP connections between two ACL images
at your site. You may have DNS problems, address resolution
problems that cause TCP to fail. Check acl;server;tcp-stream
there is an example at the end of the file you can try
between two ACL images with CL-HTTP loaded (you may test
it on a single machine first). You may try the example
with different port numbers. Once you can get a TCP-SERVER
established and exchanging data between ACL images via a
TCP-CLIENT stream, then you can expect enable-http-service
to work fine.

If the above caused an error, you don't have a TCP SERVER
enabled, all following errors are just noise. A more detailed
description of the error you get above could be useful...

Under ACL, OPEN is a general mechanism to open streams,
it will call make-instance on the CLASS argument specified.
In your case the low level UNIX substrate is probably unable
to establish a TCP (does it fail in "accept"?).
