For what needs? Why did you now install a telnet
server? I thought you wanted to get leafnode to
run.


I'm going by the following (except that I'm doing xinit):


 Leafnode should run now?




Try telnet on port 119:

  $ telnet localhost 119
  Hopefully you see something like that:

Ofcourse, there is. eselect rc restart xinetd or /etc/init.d/xinetd restart

Did you read that file?

PS: Please do NOT wrap lines of log files, it makes it very
hard to read those messages, IMO.

Yes, it is, you're right. What's showing up in the logs?

Of course not. Reading the man pages might help...

-n will not do any name resolving. So, do:

netstat -an | grep 119

In the logs. Is leafnode using xinetd, or is it run
as a standalone service? Try to restart the service
(be it xinetd or leafnode) and watch the logs. Try
to connect to leafnode and watch the logs.

You used a wrong term. That's all.

Well, no. ping is sending icmp packages. And it'll also
resolve hostnames. But that's not the main purpose of
ping. For resolving hostnames, there's host or nslookup.

Fine. Do you have a telnet server running?

When your machine is connected to a network, it has some kind of network 
interface (usually some piece of hardware). If you try to connect to 
localhost, this happens via the (logical) network interface named lo (the 
loopback interface), while a connection to a remote machine goes through 
the (physical) network interface eth0.

From the other mails you have written in this thread I meanwhile know that 
you're trying to start leafnode via xinetd (you should have mentioned this 
right at the beginning, BTW.). So here are some questions:

Did you actually check wether xinetd is running?
If yes, did you restart it after changing its config?
Is xinetd itself configured to listen on interface lo?
Is leafnode configure to listen on interface lo (not sure it needs to when 
xinetd already does)?

HTH...

typically, in your /etc/hosts file (as far as I have learnt it anyway)
you would leave the 127.0.0.1 line just with localhost.

Then put your FQDN, as well as your Shortened-domain-name on your "real
ip address" line:

$ cat /etc/hosts
127.0.0.1   localhost
172.16.0.52 orpheus orpheus.pcorp.com.au

So, looking at one of your previous posts:

10  #127.0.0.1  localhost
11  127.0.0.1   hawat.thufir.invalid arrakis localhost

(line 10 being ignored because it's commented) when you say "look for
localhost", what is localhost? it's not even in the hosts file, so
nobody knows how to get there!

I think this is what's happening anyway.

At least you have it working.  I am curious though, are
"hawat.thufir.gmail.com" and "arrakis" both names for your machine?

Thanks all, yes, the telnet is working :)

Just a few minutes ago it wasn't, but I played around with the hosts
file.  I don't understand why it's working now and not before because
I'm still using a FQDN which I was using from the beginning.  However,
I changed the arrangement of a few things:

Based on the /var/log/messages I don't think I have the FQDN correctly set.

As root a netstat -ptln might tell you if xinetd is holding the

it on the port unless there is a working connection... I'm not sure  
and have no desire to install xinetd to find out. :)

Nice quote :)

Interesting, lo versus eth0.  I don't understand the question, as I
don't know what lo means, but that might be it :)

"lo" refers to an interface?

Ah, I should've explained.  vcn.bc.ca =/= locahost, that's just a
random place to which it's possible to telnet.  I was just
demonstrating that the telnet client was working properly, that's all
:)

Yes, it does, thank you.  How do I find out why they're not available, though?

Is it a problem with the FQDN?  On re-reading the FAQ, I changed the

gmail, so...

I also have a thread on news.softwear.readers, pardon for the
multiposting.  I was just trying to address the telnet issue here. 
Most of what's been written in reply goes over my head.

Did you actually read the original mail? You don't need a telnet server to 
make a telnet connection to the NNTP server.
