[gentoo-user] Continue ftp upload without clobbering

Hi All,

Is there a way to continue uploading a large file after the ftp link fails, 
only from the point where it failed onwards?  I noticed tnftp (which I use) 
has the append command, but this appends the complete file from the start 
after the partial uploaded file, rather than continuing where it had stopped.

I am really looking for some clever way to perform the ftp equivalent of 
wget -c sort of thing and if it can do that unattended then that would be 
even better!

lftp has 'put -c'/'reput', but it may just restart from the beginning, 
depending on whether the server likes it. (I've never have to try
it...)

If you have ssh access, try sftp, I think the standard draft for sftp
does define a write offset which can be used for resuming uploads.

You need to use the REST command to tell the server the position at
which you're going to resume, and then the client must send data from
there on. (I believe)
