Description of problem:
New kernel of FC5 has a problem with downloading files larger than 1MB from a
Tru64 Unix server. I tried to stop iptables, but the problem still existed.

Another kernel that I still have and doesn't have this problem is
kernel-2.6.16-1.2122_FC5, however I am not sure if this is the latest version
without the above problem. Version of the current kernel that I am using now and
has the problem is 2.6.17-1.2157_FC5.
I used three different ftp clients and all had the same problem. I used ftp
(command prompt client that comes with FC5), ncftp and KGet.

Version-Release number of selected component (if applicable):

How reproducible:
ftp to a Tru64 Unix ftp server and try to download a file larger than 1MB.

Steps to Reproduce:
1. FTP to a Tru64 UNIX ftp server
2. find a file larger than 1MB
3. Try to get the file
Actual results:
ftp client waits infinitly to receive the file and nothing is received.

Expected results:

does it start working again if you echo 0 > /proc/sys/net/ipv4/tcp_window_scaling

I was using HP Test Drive systems at the time that I posted this bug.
Unfortunately, Tru64 Unix Servers are no longer available and consequently I am
not able to provide the requested information.
