Can't end telnet servcie in xinetd when close remote telnet cliend forcely
 
Hello there,

I setup a telnet server through the xinetd. The target linux system is built with eldk.

I can telnet the target linux system from windows.

The problem is when I directly close the telnet client program(windows) instead of 'exit' command. The xinetd seems not close the service. So when I do this 4 times(instance = 4 in the config file), the telnet client says the max number connect already reached.

I have stuck here for 2 weeks. Please help me........

Thanks.:)

1. well, don't do that ;) actually, it ought to time out eventually, there's prob a cfg somewhere (but see 2.).
2. don't use telnet, it's totaly unencrypted, inc passwds(!). Use ssh ; on MS use putty/pscp etc.
