[OAI-implementers] Problem connecting to remote sites

[Tim Brody]

AFAIK there aren't any restrictions on the cogprints site (i.e. no .htaccess
limitations), and, for my own server, there definitly aren't any
restrictions in citebase (http://citebase.eprints.org/cgi-bin/oai).

It may be that you are sitting behind a firewall, which is crossed using a
HTTP proxy. Try manually connecting to an external HTTP server using telnet
(# telnet servername 80). Also look in your Web browser's connection
settings. If you are firewalled you will need to implement proxy support
(basically connect to your proxy and send the same request, and things
should work).

N.B. CogPrints doesn't (currently) use resumptionToken flow control and
isn't very strict to the OAI protocol, so isn't necessarily a good test bed.

All the best,
Tim Brody
