can I use freeFTPd as TFTP server to store routers & switches confi?

[LAAsm2012b]

we use freeFTPd for Voip backup, now want to backup all routers & switches confi, does this free program work for them?

if yes, can anyone show me the exact CLI to copy start-config to it? I ran "copy start ftp" --> enter server IP when prompted, got "$error opening ftp://x.x.x.x/file name  (undefined error)" . it doesn't prompt me username and password, is that why I can't open the path?

if no, which program should I use here? more details, pls

thx.

r u talking about "protocol error" one? that one is fixed by myself.

but still don't know why freeFTPd doesn't allow me to save the confg file to customized directory.

That's gotta be the permissions issue.  Have you tried opening up permissions for every one so there is no restricgtion at all and see if it works?  If it works then start closing down the permissions.
