telnet: connect to address 127.0.0.1: Connection refused

Dear All

>From searching the archives, I got this:

«Go to /etc/xinetd.d/telnet

and edit the line which says **disable = yes** so it reads
**disable = no** (ignore the **)

After that change restart xinetd with the command

service xinetd restart»

that I have followed, but still getting:

$ telnet localhost 9734
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host: Connection refused
$

I am running Fedora Core 6 and I have the telnet-server package
installed.

Any further ideas?

Thanks in advance,

Paul

Where did '9734' come from?

I am trying to use the Ryacas package and from its site I get the
following:

«2. Telnet problems. If you are unable to get a connection at all try
to connect to yacas manually using:
telnet localhost 9734
and if that fails there is likely a configuration problem with telnet
on your machine.»

Ryacas is a package of R and its site is at

http://code.google.com/p/ryacas/

Use `netstat -nl | grep -- ^tcp` to identify listening services and
`lsof -i:<port>` (where "<port>" is the port-number identified by
netstat) to identify what service is listening on said port. Once
you've verified what port you're connecting to, show us a listing of
your ipchains (`iptables -nL`) rules.

If `netstat` and `lsof` are foreign to you, use `nmap -p 1-65535
localhost` to see what services you've got open...

I get this:

Well, judeing from the output of nmap, I think it safe to say we know
why you're getting a connection refused when you try to telnet to
9734... there's nothing running on 9734.

I bet you don't have any trouble connecting to the standard telnet
port, so what happens when you just `telnet localhost`?

Cheers,

Okay, you have some massive confusion. A 'telnet server' is used to
provide the telnet service and has nothing to do with some other
services, such as Ryacas. The confusion comes from the fact that you
are using the telnet *client* to connect to a Ryacas server. Whether or
not you have a telnet server won't make any difference, since that's
not what you're trying to connect to.

The steps that you took to get your telnet server running aren't going
to help you at all. You need to get Ryacas running, and then you can
connect to it with any client you want.
