Hello!
I use lftp-3.5.15 (with a patch delivered by Alexander) to reverse mirror files
in a WLAN environment, so I have frequent trouble with connection breaks.
After a lot of testing and very helpful advice from this group, I'm now using
the following parameters:
set ftp:list-empty-ok true
set net:timeout 10
set net:max-retries 2
set net:reconnect-interval-base 5
set net:reconnect-interval-multiplier 1
open ${FTPHOST}
user ${FTPUSR} ${FTPPW}
mirror -R --delete-first -L -e --max-errors=1 -p ${sourceDir} ${targetDir}
After a connection break, lftp quits with an error message. Hope this helps!
Regards,
Michael

Greetings,
while running lftp to mirror a significant amount of files, at some
point, it hangs.
The command looks something like:
lftp -c "set ftp:ssl-allow false;open -u user,password
ftp://ftp.site.com;mirror --reverse --dereference
--Remove-source-files --log=/path/to/log /path/to/files/ /"
Some nights, it works flawlessly. On others, however I get stuck. The
log doesn't update, and the strace below repeats.
I don't know if it helps, but I'm uploading to a yahoo small-business
web-server, and they do not have a good reputation for reliability.
Still, I'm not sure why lftp doesn't seem to reconnect. If I kill lftp
and restart it by hand it starts again and works.
Any thoughts? Thanks so much,
Nate
