SCP Download Problem

2010-08-12 11:01

Hi,
since a while it's not possible to download a file which is bigger than 10MB while using a scp connection. tried on different servers. sftp works great, but i need scp for doing some remote commands.

don't remeber the version when it started, but in older versions it worked whithout problems.

right now i'm using 4.2.8

forgot to mention, the error message looks like this

Copying file 'testfile_11mb.zip' fatally failed. Copying files from remote side failed.

Please post a full log file showing the problem.

To generate log file, enable logging, log in to your server and do the operation and only the operation that causes the error. For posting extensive logs you may use pastebin or similar application. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you may email it to me. You will find my address (if you log in) in my forum profile. Please include link back to this topic in your email.

As you can see, the server closed the connection. Can you see in the server's log file, what is wrong.

I'm also running into this bug. It seems to be an ssh bug, but is triggered by the client program.

Here is the information requested from the previous poster that should be enough to track this down. Another poster in another thread mentioned that the last working version was 4.1.9. I can't confirm the exact version number yet, but in the past I have transferred large files from my server, using winscp with no problem. So this does seem to be something that was changed in recent versions of winscp.

I'm using Redhat Enterprise Linux 3, with the latest available openssh for this platform, which is 3.6.1p2 with their backported fixes.

Also was using WinSCP 4.2.7 on Windows XP, upgraded to version 4.3 beta with same results.

this is the info on this error from my server's logfile, /var/log/secure:
Nov 8 19:21:00 server sshd[3621]: fatal: buffer_append_space: alloc 10514432 not supported
Nov 8 19:26:52 server sshd[4080]: fatal: buffer_append_space: alloc 10522624 not supported
Nov 8 19:28:43 server sshd[4363]: fatal: buffer_append_space: alloc 10522624 not supported

Here is some info on the bug that may be helpful for making a workaround:
https://bugzilla.redhat.com/show_bug.cgi?id=184357

https://bugzilla.mindrot.org/show_bug.cgi?id=896

let me know if you need anything further, thanks.
