One of the very few programs that I missed moving from Windows to Ubuntu last spring was FileZilla. There are some FTP clients available, but I haven’t found any that I liked quite as much. If you look on their project page on SourceForge, it states “FileZilla is a fast FTP and SFTP client for Windows with a lot of features”. Well here is a cool little find:
There are distributions for Linux, Mac and BSD.
It is clearly not a supported product and not yet out of development, but I have found it to be remarkably stable.
