luable bandwidth(15)!Most people will not want to monitor their network status 24 hours a day and disconnect everyone who decides to hang around for a while (especially on large networks). This is why timeout was invented.By setting a timeout value to a daemon (this can be done during the setup process or by running a setup program or entering some sort of an options box) you can make it close the connection on anyone who connets to it and does nothing for over than the timeout value.For example: you put a daemon on port 17 and tell it to timeout after 2.5 seconds. If someone will connect to your daemon and will not type anything for over than 2.5 seconds the daemon will close down the connection and that person will have to reconnect and start typing something before the daemon times out and throws him out.This is why webservers have a short timeout of 2 seconds (most people connect to webservers using client programs(16), and these programs "type" really fast...).6. TCP - stands for Transfer Control Protocol. TCP is a protocol that is used for transferring data through networks (the Internet, local networks etc'). TCP is much more reliable than UDP since it uses several precautions, such as sequence numbers and all sorts of nifty header flags and all (see the excellent article called 'IP Spoofing Demystified' at the Books Section in http://blacksun.box.sk for lots of info regarding TCP (a real MUST READ!!)).TCP's only disadvantage is that it is a bit slower than UDP, but it is more reliable, hence it is used to transfer sensitive files (such as programs - if you lose a single bit of the file, the whole thing is useless).7. UDP - stands for User Datagram Protocol. UDP is a protocol that is used for transferring data through networks (the Internet, local networks etc'). UDP is less reliable than TCP (see the excellent article called 'IP Spoofing Demystified' at the Books Section in http://blacksun.box.sk for lots of info regarding UDP (...
