           Summary: buffer overflow in receive_file_entry
           Product: rsync
           Version: 2.6.0
          Platform: Other
        OS/Version: Linux
            Status: NEW

As a gentoo user I use rsync quite a lot, and am generally happy with your
product. Since not so long I've been getting rsync errors when connecting with
a timeout of 30secs. My internet connection is quite fast, but my laptop HDD is
dead slow. I suspect the time-out was the problem, since changing it to 180s
solved my problems. But I didn't have time to find out about this solution
before today.

Normally I get errors of this kind:
dev-libs/gdome2/
dev-libs/geoip/
dev-libs/gmp/
rsync: connection unexpectedly closed (3412222 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(189)
>>> retry ...


>>> Starting retry 1 of 3 with rsync://81.223.20.162/gentoo-portage
>>> checking server timestamp ...

But this problems seems solved by changing my timeout settings.

Now, while I was experimenting with rsync options, trying to solve this problem
this morning I ran into some extreme rsync behaviour that might be interesting
to you developers:
