Hi,
Below is my tcpdump message from machine A (123.123.123.123), machine B with
213.213.213.213 unable to telnet into machine A. However machine B is able
to telnet to other server. Other machines can telnet into machine A other
than machine B, there is no firewall or tcpwrapper enable.
>From the message below, I still can't figure out which refuse which machine
and why?
