I'm currently in a situation where I have very limited access to a server, but need to upload and download a significant amount of files contained within a single directory structure. I don't have SSH access, so I can't use SCP - and rsync isn't an option either unfortunately.
I'm currently using ncftpput, which is great but seems to be quite slow (in spite of a fast connection).
Is there an alternative / better method I could look into?
(Please accept my apologies if this has been covered, I did a quick search prior to posting but didn't find anything that specifically answered my question)
Try using LFTP: http://lftp.yar.ru/
If you have a good connection, I would recommend mounting the ftp server via the GNOME or KDE file managers, or else using CurlFtpFS . Then you can treat it like just another folder.
I'm not familiar with ncftpput
. For non-interactive FTP, I've always used the Perl Net::FTP module -- http://perldoc.perl.org/Net/FTP.html
This will be faster because you can login, then do all the transfers at once (it seems from a cursory glance that you execute ncftpput
once for each file get/put).
Just remember to NEVER use ASCII mangling! This is the default, so use:
$ftp->binary
ASCII mangling needs to die in the same fire with MySQL automatic-timezone-interpreting.
Since I always end up having a problem with this, I'll post my notes here:
One thing I always get to confuse is the syntax; so below there is a bash
tester script which creates some temporary directories, then starts a temporary ftp server, and compares rsync
(in plain local file mode, as it doesn't support ftp) with lftp
and ftpsync
.
The thing is - you can use rsync /path/to/local /path/to/remote/
, and rsync will automatically figure out, that you want a local
subdirectory created under remote
; however, for lftp
or ftpsync
you have to specify the target directory manually, as in ... /path/to/local /path/to/remote/local
(if it doesn't exist it will be created).
You can find the ftpserver-cli.py
in How do I temporarily run an FTP server? - Ask Ubuntu ; and ftpsync
is here: FTPsync (however, note it is buggy; see also Search/grep ftp remote filenames - Unix & Linux Stack Exchange );
Here is a shortened output of the puttest.sh
script, showing the recursive put behavior in different cases:
$ bash puttest.sh

No mention of ncftp ?
