screen(1) provides detachable, transportable terminal emulations, and works without X. Sounds like what you want. To answer your original question: As you probably know, IP itself is stateless. As long as your IP address does not change, the IP layer will not notice if you leave for a year. In practice, however, things do not work as well. For one, if your gateway is also a connection end-point, any applications you have running will barf when the gateway interface goes down and the address the socket was bound to disappears. Additionally, many higher-level protocols, including TCP itself, may send "keep-alive" messages to make sure the other end is there, and timeout your connection if not. Finally, even fairly "passive" applications like TELNET will timeout if any activity occurs on either end while the connection is down. In short, if everything is near-perfect, you *might* be able to recover from a very brief lost modem connection. For "detached sessions", you will need something that is explicitly designed to separate any connection state from your end. -- Ben Scott <[EMAIL PROTECTED]> | The opinions expressed in this message are those of the author and do not | | necessarily represent the views or policy of any other person, entity or | | organization.
