#272780 - 22/12/2005 17:05 Problems uploading large files via FTP
ithoughti old hand Registered: 17/07/2001 Posts: 721 Loc: Boston, MA USA	Hi all.... I've been trying to upload some large .zip files >350mb up to >1GB to my site. I've been using SmartFTP and/or WsFTP on my XP machine. I have a cable connection so the upload speeds are not all that great. Generally the timers on the FTP programs say about 3 hours for a 400mb file at about 44KB/s (or something like that) All times I have tried to upload this file, it has quit at about 300Mb, sometimes less, sometimes more. I think that this mostly has to do with my cable connection because I tried uploading from work with SmartFTP and everything worked fine. Of course at work I can upload that file in under 10 minutes. Does anyone have an idea on how to keep the connection active? I've pretty much exhausted the options in both programs for 'keep connection active' and 'failed upload' retry times etc and nothing seems to work. thanks for the help. _________________________ --------- //matt

I use FileZilla and if you have 'use multiple connections' enabled (it is by default), it will keep the connection alive by doing stuff like this every few seconds:
Code:

I don't know what your OS is, but searching for "ftp resume upload" should point you in the right direction. _________________________ Bitt Faulk

No magic required for that, either.. just standard SSH. I even use "SSH filesystem" under Linux for remote access to files on my home server when I'm elsewhere. Again, only an SSH server required for that. Cheers
