The problem with ftp (and rcp) is that the terminal (or window) is tied up for the duration, and I have to sit there and hold its hand to get it to work right. Well, I think we should differentiate ftp the protocol and ftp the program. You can implement a ftp client with interactive mode, batch mode, and half batch mode (you login interactively, find the file you want to transfer, and tell the ftp to get rid of the control terminal and do the transfering in the background without supervision). If you like the challenge you can also design and implement a script language for it. A little note: I think that a you will already find a decent implementation for all this, as perl scripts, in any comp.lang.perl archive. On the other hand you can also have interactive OSI style file transfer, as it has been pointed out (ISODE). In this country (UK) however it is rarely available (the offline variety is prevalent, and apparently the reason is a conscious decision to "minimize network traffic" resulting from interactive use, as well as a feeling that interactive access is less secure), and it is mainly used gatewayed to Internet FTP servers... :-). I still reckon that the move to TCP/IP tunnelled over X.25 public networks (from local TCP/IP based lan to remote TCP/IP based LAN via an OSI WAN) is still going on strongly in Europe, especially on the Continent (but also in the UK), and in the academic community. Migration *to* TCP/IP indeed... -- Piercarlo "Peter" Grandi | ARPA: pcg%cs.aber.ac.uk@nsfnet-relay.ac.uk Dept of CS, UCW Aberystwyth | UUCP: ...!mcsun!ukc!aber-cs!pcg Penglais, Aberystwyth SY23 3BZ, UK | INET: pcg@cs.aber.ac.uk
