To day I established a lab that simulates traffic between the FTP server and a cisco router with software 3Cdeamon
Once I transferred file size 128 Byte over the router, the file transferred twice before asking whether to reboot the Flash memory:
"Erase flash: before copying? [Confirm]"
Then when I disconfirm the boot Flash, the file is moved on twice more, and the router received a single file.
Why FTP server allows himself to load on the network copies of the file - in vain??
When I spent a larger file (2M) the server sent 15% of original size file in byte in vain.
Please your help
