FTP, or File Transfer Protocol, is an easy-to-understand Internet service, but providing a good interface and helpful add-ons has meant that a good FTP program is disproportionately more powerful than you’d expect. That’s certainly true of Interarchy, one of the longest-standing Internet programs still around (only Fetch, the granddaddy of Macintosh FTP clients, has been around longer). Interarchy does basic FTP, several forms of secure FTP, and HTTP, and for all of them it offers a variety of scheduling, repeating, and mirroring options. But Interarchy goes well beyond file transfer with its network monitoring capabilities, which turn it into an invaluable part of any network administrator’s toolkit. User reviews of Interarchy 7.0 have been stellar, with a number of people on TidBITS Talk raving about the upgrade. Be sure to check it out for yourself.
