Apart from what the other people already told you: telnet is a dinosaur. It has been designed to connect whatever character-mode applications might exist on this planet, starting from a block terminal hooked via the network to a prehistoric IBM mainframe up to full-screen character-at-a-time textmode applications of today. The telnet protocol evolved over time, and there are too many broken (or historic) implementations around, so the communication peers often guess what mode the other peer might support. While being thought to be efficient in theory (with things like linemode, and you might value this feature when working over a slow link), almost all practical implementations suck rocks. Also, telnet clients usually can be used as a generic TCP client, by saying ``telnet host port'', or even ``telnet host service''. Try ``telnet localhost ftp'', for example. (Hint: type `quit' to get rid of it, or use the telnet escape ^].) Rlogin is a fairly simple protocol, OTOH. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
