I've been running httrack on a Linux box successfully but
then tried it on and alternative box. When I try any url, I
get the error:

Error: t"Receive Error" (-4) after 2 retries at link
www.memex.com/robots.txt (from primary/primary)
10:48:29.memex.cError: b"Receive Error" (-4) after 2 retries
at link www.memex.com/ (from primary/primary)

I can, however, access the local intranet and grab pages
from there. I though this might be a firewall issue, but it
is accpeting connections on all ports.

I'm using: Red Hat Enterprise Linux WS release 2.1 (Tampa)
Kernel 2.4.9-e.12smp on an i686

Any suggestions why this is happening?
