Not sure if this fits in cPanel forums, but maybe somebody can at least try and provide some workaround to this.

We're using Pure-FTPD and over the last 2 years, we noticed a very frustrating behavior. In FileZilla client, whenever somebody uploads a (big) file, the upload immediately gets renamed to some serial number (e.g.: .pureftpd-upload.4bca436d.15.2455.1bb2fab2) but it frequently happens that mid-way thru the upload, the client's IP address changes. What happens next is one of the 2 things:

1) The file gets re-uploaded from scratch.

2) The file upload resumes.

More often than not, scenario #1 happens. If the client refreshes the directory in FileZilla client, it seems like the serial-named file (e.g.: .pureftpd-upload.4bca436d.15.2455.1bb2fab2) gets erased or an attempt to rename it back to the normal file name fails and the file gets deleted!

This is becoming a very aggravating issue because some dump files are as big as 4GB and on sh*tty internet access such as 800kbps upload, this takes 1.5 day! Imagine this happening twice for the same file and now it takes 3 days to finish the upload (if the IP address does not change again, which it does on ASDL connections almost every day) !

Anything that can be done to stop this from happening? (inb4 set a cron job in cPanel to make a copy of the .pureftpd-upload.* files every hour)

Would it work better under Pro-FTPD ?

Hi @Benjamin D.

This is specific to the fact that the file upload by pureftpd is a tmp file until the upload completes - this is an unchangeable behavior of PureFTPd. The tmp file is created to track progress. Does the same behavior occur when using proftpd? Based on these circumstances: poor internet connection and dynamic IP addresses there's really not a lot cPanel has control of in this respect.

Yes I know, but I was considering using ProFTPd instead, but I'm not sure if the same behavior will happen and I also have some clients using out of cPanel FTP users, which cPanel cannot offer to us at the moment. It's a combination of a master R/W user made outside of cPanel and a bunch of R/O users managed by cPanel and I fear it will break everything if I switch to ProFTPd.

Well, I've set a cron job to duplicate on the side uploads bigger than 1GB every hour, so next time some sh*tty DSL disconnection happens, at least we'll be able to roll back easily. Thanks, you can close this thread.
