No ftp transport?

writing because perhaps I'm overlooking the obvious. However looking
in transfer.rb I see:
------
session_map[session] = case transport
when :sftp
prepare_sftp_transfer(session_from, session_to, session)
when :scp
prepare_scp_transfer(session_from, session_to, session)
else
raise ArgumentError, "unsupported transport type:
#{transport.inspect}"
end
end
------
Is there a normal solution to using ftp if desired? Is this something
I should try to add myself?

top of SSH, and everything it uses to communicate with the servers
runs over that transport (e.g., SSH itself, SFTP, and SCP). To add FTP
would require a significant change to how parallel commands are
processed. (It would actually be fairly hard to make FTP run in
parallel with other FTP commands, since it is a synchronous protocol).
Also, FTP is extremely insecure (you realize it sends the password in
clear text, generally, right?). I'd strongly recommend you avoid FTP.

added to that single command without requiring any changes to running
commands. I haven't delved too deeply yet so let me know if this is
crazy talk.

(via a utility account - not mine) to repository server within the
company firewall. Of course this is a server I don't control.

The single-server scenario (which is just a special case of what
Capistrano handles) could do FTP easily enough: you could even do it
yourself within a task, manually, with Ruby's Net::FTP library.
However, the general case (FTP'ing something to multiple servers at
the same time) is going to be non-trivial, I suspect, and almost
certainly won't just "drop in". I'd be happy to be wrong, though.

If you can SSH, you should be able to SCP or SFTP, too? Unless the
admins have disabled both of those, which is possible, but it might be
worth communicating with them about it, since either of those are
infinitely to be preferred over FTP.

Thanks I just put together a shell script to do the ftp through a
"run" but this seems better. It seems like a generic solution won't be
easy but I can respond with my final solution if anyone else has a
similar single-server upload via ftp problem.

Unfortunately, I'd already tried ssh and it's not allowing it. I've
requested the ability to scp or sftp but we'll see. I have a feeling
this box was setup as ftp only for some purpose (perhaps 3rd party
integration or something?) and also purposely has limited other
functionality. Hopefully I'm wrong.

Oh, wow, you can't even SSH? Then yeah, your script is going to be the
way to go. Capistrano won't work for that scenario, at all. Capistrano
really is exclusively SSH (by design).
