CentOS - Sep 2007 - Able to open TCP session, but unable to receive html content

I seem to be having a problem with all of my CentOS5 machines, which do not
seem to be a problem with CentOS4.4:

[garron at MailScanner ~]$ telnet www.debtbusterloans.com 80
Trying 87.86.7.52...
Connected to www.debtbusterloans.com (87.86.7.52).
Escape character is '^]'.
GET /
HTTP/1.1 200 OK
Date: Thu, 27 Sep 2007 10:34:24 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727
Pragma: no-cache
...

Yet:

[root at eagle ~]# telnet www.debtbusterloans.com 80
Trying 87.86.7.52...
Connected to www.debtbusterloans.com (87.86.7.52).
Escape character is '^]'.
GET /

Connection closed by foreign host.
[root at eagle ~]#

---

I've done a tcpdump, and it would appear as if I receive a TCP RST when
attempting to request pages - yet this appears to work for other websites.

So far, I've been able to narrow down that this is only happening on my
CentOS5 machines and not CentOS4.4Server installations.

Could anyone please advise? Its the strangest problem - especially as it
only affects certain websites.

Regards,
Garron Kramer

Hi

Are eagle and Mailscanner on the same network, on the same switch/hub ?
Can you post  your tcpdump for both connection.
What is the NIC ?
