Hello again,
is there anybody who can tell me something about this issue? Is it a bug or a feature?
Thanx and best regards
Stefan.
Hello,
I'm using lftp (old version 3.2.1) for a longer time without problems, and now I have updated to version 3.5.6 but found a problem (bug?) regarding the net:timeout setting:
When trying to upload a file which transfer time takes more than the value set in net:timeout, the transfer restarts at the end because of supposed timeout, although the upload has been active all the time
Example:
- File upload with about 200 MB takes approximately 25 seconds
- set net:timeout 10s
- set net:idle 3m
=> After _complete_ transfer the client seems to wait for a put confirmation (FileCopy(139ea0) enters state CONFIRM_WAIT), but in same moment recognizes the timeout and starts reconnecting - and everything starts again from the beginning, because the server does not allow continuation of transfer.
Is this a bug? Or is there another setting I may forgot (I don't want to set the timeout to a too high value because than other real timeouts wouldn't be caught)...
Here is my debug log:

Thank you and best regards

Hey, thanks for your response.
But I do think that there must have been changed something in lftp, as older version 3.2.1 works fine with the same server...
Furthermore, as I described, the problem does only occure when transfer time is longer than net:timeout value, so there seems to be any interconnection between them In fact, the lftp client doesn't even wait for a confirmation, moreover, it catches a timeout immediately, so there is no chance for the server to confirm successful transfer.

It is certainly a bug, but probably not in lftp.
lftp waits for server reply which confirms successful transfer, but does not
receive it for some reason.

Hi,
this patch seems to work! 
Unfortunately I can't say anything about potential side effects, but for now everything seems to be fine.
Thanks a lot and best regards

Sir:
I am a newbie, but enjoy lftp which is a power and easy ftp client to used. But I met a problem when connect to a Pure-FTPd(TLS) on my FreeBSD.
1. Install lftp via FreeBSD Ports, there is Lftp
Version 3.5.6 with
Libraries used: Readline 5.1, Expat 2.0.0, OpenSSL 0.9.8d 28 Sep 2006, libiconv 1.9.
2. Connect to ProFTPd out of our NAT device, works. But failed when connect to a Pure-FTPd(TLS), looks lftp session
death at 'ls' command(but I can do 'cd' to sub-directory, for example 'cd public_html'), no return information.
I searched, find there are
similar situation, like 1. Problems with lftp and PureFTPd server (gnutls bug?) links is http://www.mail-archive.com/lftp <at> uniyar.ac.ru/msg02610.html
, 2. FreeBSD SSL/TLS problem, links is http://www.mail-archive.com/lftp <at> uniyar.ac.ru/msg01518.html
.
Here is part of leftp debug out put information:
