Hi.
It seems that I can telnet every listening port in
my RedHat 6.2 box. Whenever I telnet a port, say 113,
I get a ^] prompt and typing that will get me to the
telnet> prompt. Is there any known security issues
regarding that ? If there are, how would I know if
somebody telnet to my ports ? What stats or logs
would give me those information ? I tried to use ipchains
to block the source port but it seems that the port is
not permanent coz when I tried to block 0-10000, it didn't
connect at first but later it did.
Thanks.
