I have an old FTP server (IIS) and a new FTP server (ubuntu 8, VSFTPD) with the identical usernames, passwords and data. Everyone can login fine, upload and download files just fine. Everything was working smoothly, so i thought.
When i transferred all the data from ISS to ubuntu, and didn't have any problems (over 20 GB worth, many large files)
Then i noticed all of a sudden, a week later, that i couldn't upload any large files onto EITHER server. I COULD upload small files (a few MB). I got THE SAME error message on EACH server:
"An error occuret copying a file to the FTP server. Make sure you have permission to put files on the server.
The connection with the server was reset"
On the ubuntu server in VSFTPD I commented out the line that said to use port 20 for transfers.
I COULD transfer a file that was 56MB
I COULD NOT transfer a smaller file of 25MB (i got the error listed above)
There is plenty of space on either server
Whats going on here!?!?!?!
(I'm concerned with getting the ubuntu server working, not the IIS, although I wont complain if I get that working as well)
