Did you run:
lsof | grep tel
on your machine?
What did it say about telnet sockets?
Did you try to connect via telnet over wifi?
What happened?
If you did connect over wifi, did telnetd ask you for a password?
This additional information would help us understand the problem you are seeing as a "hole".
Here is an example of the lsof output, filtered by grep, (for sshd, not telnet, and on a non-kindle machine, but the listing format will be the same):
Code:
sshd 1304 root 3u IPv4 9587 0t0 TCP *:ssh (LISTEN)
sshd 1304 root 4u IPv6 9589 0t0 TCP *:ssh (LISTEN)
I.E: The above machine has two network sockets open (IPv4 and IPv6) using TCP protocol, listening on all (*) address:port=ssh combinations.
If you find telnet listening on the address (or all addresses) of the Wifi interface, then check your firewall incoming (state=new) rules for the Telnet port on that Wifi interface.
Since it does the program no good to listen, if packets can't get through your firewall.
