[wplug] talk and xinetd?

[Poyner, Brandon]

I believe the Linux talk client prefers to use ntalk.  You should have
an ntalk file in xinetd.d, enable that one as well.  

# chkconfig --list talk
talk            on
# chkconfig --list ntalk
ntalk           on
# netstat -a | grep talk
udp        0      0 *:talk                  *:*
udp        0      0 *:ntalk                 *:*
udp        0      0 localhost.localdo:32867 localhost.localdo:ntalk
ESTABLISHED
udp        0      0 localhost:32868         localhost:ntalk
ESTABLISHED

Subject: [wplug] talk and xinetd?


I thought this would be simple, but it seems complex.  I am trying to
get 
talk to work on my server running Redhat 9 with xinetd.  I modified the 
'talk' file in the /etc/xinetd.d directory to include "disable = no" and

restarted xinetd.  'talk' now shows up in chkconfig:

$ chkconfig --list talk
talk		on
$
.. and in netstat:

$ netstat -a | grep talk
udp        0      0 *:talk                  *:*
udp        0      0 *:talk                  *:*
udp        0      0 *:talk                  *:*
$


... yes, three times (is THAT a problem?)

But when I say 'talk user' where "user" is an online person other than
me, 
the talk window tells me, "Error reading from talk daemon: connection 
refused".  

I put a line in my iptables firewall (the very first line in the INPUT 
chain) which LOGs any udp packets on port 'talk', and it's not showing 
anything.  Is there somewhere upstream of the firewall that this could
be 
getting stopped?  The user is logged in on the same machine, so it
shoudl 
be going through the loopback interface (right?) which I have wide open.

I'm just a little puzzled.  Any ideas?
