It could be that you are using inetd instead of daemons to run
services. That way they are only called when needed. Check
/etc/inetd.conf to make sure that telnet is a service provided, and that
the program called when there is port traffic is installed. From my
/etc/inetd.conf file (Debian), I have included the line for telnet,
which I have disabled on my system by commenting it out.
# <service_name> <sock_type> <proto> <flags> <user> <server_path> <args>
#:STANDARD: These are standard services.
#telnet stream tcp nowait telnetd.telnetd /usr/sbin/tcpd
/usr/sbin/in.telnetd
here, inetd listens to port 23 and calls /usr/sbin/in.telnetd for a
telnet connection
you can change the file and then (in Debian at least) restart inetd as in
/etc/init.d/inetd restart
then telnet localhost or check with netstat to see if the port is being
listened to
as above, if I try
telnet localhost
I receive the response
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused
uncommented and with inetd restarted, I receive the login prompt
