And how do you know when it fails and WHERE it failed? You don't, and that's why I recommend doing this with Perl. It's easy (I have sample scripts at the links I gave above) and you have total control of errors..      |

'sftp' is one such, and it's basically SCP with an interface, suffering most of the flaws of SCP and rcp access. The interface is far less flexible than FTP, it normally has no chroot capability and thus no way to restrict clients from browsing the rest of the filesystem, and it mishandles symlinks. These are reasons that I like WebDAV over HTTPS: it has most if not all of the features of FTP, it runs on the HTTPS port, and is easily implemented with a basic Apache installation with a great deal of flexibility. |

Its not secure and adding any sort of robust error checking turns the simple script into something complicated enought that something like Perl quickly becomes the better solution. However, that said, sometimes one really wants or needs to do FTP and this is simple enough to remember and just type in. |

However, on my Gentoo boxes, FTP (net-ftp/ftp) is built with SSl support. However, this can be problematic, because, if one needs the NAT firewall to react properly to the ftp commands going across the firewall, it won't happen with an encrypted session. |
