Re: Limitation in SCP?

[Michael Uman <Michael_Uman at sdesigns dot com>]

Hello,
I had a similar problem copying a file from RH9.0 linux to WinXP Cygwin
where the copy stopped at 128MB every time I tried to copy the file... I
ended up bzipping the file and scping it...

I can provide more information later {I am away from that particular
machine}...

It copies diligently for the first 20-40MB (exactly where it stops varies from run to run), then CPU usage drops to zero, the file stops growing on the receiving end, there's no apparent network traffic, and everything just pretty much halts.  A ps shows the scp task running, but not doing anything.
