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 2. 3. Expected Results: The file should be copied.

Are you sure that the problem isn't the filesystem?
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)
if you add: -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE to your CFLAGS, does it work ?
yes, adding these CFLAGS solved the problem. I can copy and receive large files now.
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 ...
well, get back to us
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. ----8<---- 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 ----8<---- I thought computers where rational... :-/ I upgraded to openssh 4 now, it works too without extra CFLAGS.
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
