Take a look in /var/log/secure and you'll probably find that 
the connections are being denied by tcpd.  Add these lines
to /etc/hosts.allow

in.telnetd: ALL at 192.168.1.1
in.ftpd:    ALL at 192.168.1.1

Replace 192.168.1.1 with the IP address of your machine.
If you want to allow access to anyone on your local network,
use 192.168.1. rather than 192.168.1.1.

Type man hosts.allow for more info.
