fetch hangs during Make, portupgrade -a, or portmanager -u..

[Dinesh Pandian]

Good day all!

Please help me out with a really annoying little problem that bugs me
everytime I try to install applications from ports.

When I try to run portupgrade -a  or  portmanager -u,
when Make fetches the files from the servers, fetch
normally hangs randomly sometime through the downloading
of the distfile. The only solution I've thought about is aborting
the upgrade procedure and issuing the same command again,
hoping that fetch resumes where it left off.

In bigger files, > 5MB, I'd have to repeat this process several
times to download a single distfile.

I've tried setting the FTP_PASSIVE_MODE env ON and OFF
to no avail.

I can't seem to find a problem with the internet connection
as httpd and ftpd works perfectly fine!

Please help.

TIA,
Dinesh
