[JDEV] jserver and etherxd

[Koichi Moriyama]

Thomas and others who may be familiar with networking configuration, 

Fist of all, I'd like to apologize that the topic I'm asking are
becoming non-Jabber specific issue rather than interests for the
Jabber developers.  For this, let me report what I've been doing
on/with Jabber AFTER the demo on this coming Wednesday.

As Thomas guessed, some configurations of my Linux box seems to be
wrong.  At least I found that telnet to local loopback were denied,
and solved -- it had had wrong /etc/hosts.allow and /etc/hosts.deny.

Now, telnet with "localhost" or short hostname works like 

    % telnet localhost
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.
    login:

    % telnet morimori4
    rying 199.77.128.133...
    Connected to morimori4.cc.gt.atl.ga.us.
    Escape character is '^]'.
    login:

but telnet with FQDN (long hostname) doesn't work...

    % telnet morimori4.cc.gt.atl.ga.us
    morimori4.cc.gt.atl.ga.us: Unknown host

The other strange thing I found is 

    % hostname
    morimori4.cc.gt.atl.ga.us
    % hostname -s			# -s gives short host name
    hostname: Unknown host
    % hostname -f			# -f gives FQDN (long host name)
    hostname: Unknown host

These results should be wrong and need to be solved.  Does anyone have
any ideas ?  Please allow me to show some configuration files after my
short signature...

Although I thought just "morimori4" (without domain name) can be used
as a Jabber server name which is given to jserver.xml like

    <default>morimori4</default>

instead of giving morimori4.cc.gt.atl.ga.us, the results was the same.
(didn't work.)

Followings are the files which seem to be required to maintain to set
up the isolated networkd...  I removed /etc/resolv.conf.
