Question 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.

Attachment: xinted.conf
------------------------------------------------------------------------#
# Simple configuration file for xinetd
#
# Some defaults, and include /etc/xinetd.d/

defaults
{
instances = 10
log_type = SYSLOG authpriv
log_on_success = HOST PID
log_on_failure = HOST
cps = 25 30
}

# description: The telnet server serves telnet sessions; it uses \
# unencrypted username/password pairs for authentication.
service telnet
{
instances = 4
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID
disable = no
}

#includedir /etc/xinetd.d

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.
