rsync problem behind a router

[Chad Moss]

That's what I originally though too...I've tried it on one small
idex.htm file, and it does the same thing...

Does it work for very small transfers?

Does it work with --bwlimit set low enough so you never saturate your
link?

I can not rsync large amounts of data through my LinkSys without using
the
--bwlimit option.  My LinkSys is doing NAT.  I think it loses track of
the
address translation for the ssh connection under load.  Then the ssh
session just stops.  I use --bwlimit=100, which is a third of the
available bandwidth on the far end, and it just works.

It's not a problem particular to rsync, other ssh sessions sometimes
hang
too.  I just have more problems with rsync because I move more data that
way.  I always use "screen" for interactive sessions.

Could be a different problem, mine would often transfer quite a few
files
before stopping.
