John, If there has been any further chat about this I've missed it or maybe Thanksgiving has quieted everything down for the long weekend.
I'm here just to make a quick comment over "interactive mode". I guess this is a reference to the FTP connection over which commands and responses are exchanged - and which, I believe, uses some cut-down version of TELNET. This exchange is characterised by the use of port 21 on the machine running the FTP server. Simple use of the traditional FTP actually performs data transfers using port 20 on the FTP server. I expect it can all get a lot more complicated than this. I know this well since, in a long forgotten flavour of AnyNet, the sockets over SNA version which permi - I guess I'm obliged to use the past tense - permitted a customer to run these wonderful IP-based programs over his well-established, well-understood, well-ordered and predictable SNA network, marketing people, check the bumpf if it's still to be found, always used the TELNET port, 23, as an example of a port which should be mapped to the SNA "interactive" class of service (COS) and the FTP port, 21, as an example of a port which should be mapped to the SNA "batch" COS - which is rubbish, of course. What they should have said - if there was an ounce of savvy among them - is that port 21 should also be associated with the SNA "interactive" COS and it's port 20 which should have been used as an example of a port to be associated with the SNA "batch" COS. Chris Mason Again today the newsgroup server is obliging me to remove the "Original Message". In essence, as far as this post is concerned, John Giltner, was asking what "interactive mode" in connection with some flavour of FTP called SFTP which is what the thread is really all about. If someone knows how to get round this unfriendly behaviour of the server, please let me know. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
