Description Mark 2005-02-01 06:17:55 UTC
I don't know why but I have this problem since gentoo 1.4: I cannot scp a large file from or to my PC, when scp reaches 2GB it stands still.
I'm using openssh-3.9_p1-r1

I disabled all my CFLAGS but this had no effect.

Reproducible: Always
Steps to Reproduce:
1. scp a >2GB file

Expected Results:  
The file should be copied.

Comment 1 Carsten Lohrke (RETIRED) gentoo-dev 2005-02-01 08:16:06 UTC
Are you sure that the problem isn't the filesystem?
Comment 2 Mark 2005-02-03 01:19:25 UTC
reiser 3.6 on my machine has no 2GB limit (reiser 3.6 allows a filesize of 2^60 bytes). If there were a limit I couldn't even store a 4GB file on it.
The other PCs I want to copy my files to can scp big files (they are running debian with ext3)
Comment 3 SpanKY gentoo-dev 2005-03-13 02:27:14 UTC
if you add:
to your CFLAGS, does it work ?
Comment 4 Mark 2005-03-14 04:03:52 UTC
yes, adding these CFLAGS solved the problem. I can copy and receive large files now.
Comment 5 SpanKY gentoo-dev 2005-03-14 07:11:27 UTC
could you run `emerge openssh >& log` w/out adding those defines to your CFLAGS and post the logfile here ?  the configure script *should* detect and enable LFS for you ...
Comment 6 SpanKY gentoo-dev 2005-03-16 17:12:39 UTC
well, get back to us
Comment 7 Mark 2005-03-17 06:10:54 UTC
This is stange. I removed those CFLAGS and emerged 3.9 again: it works though it didn't work before for a long time. I can't explain why, I changed nothing.

checking for special C compiler options needed for large files... no
checking for _FILE_OFFSET_BITS value needed for large files... 64
checking for _LARGE_FILES value needed for large files... no

I thought computers where rational... :-/

I upgraded to openssh 4 now, it works too without extra CFLAGS.
Comment 8 SpanKY gentoo-dev 2005-03-17 06:34:24 UTC
ah, computers acting irrationally is a feature, it must have forgotten to tell you that ;)

please re-open w/appropriate logs if this starts happening again
