talk ntalk

1997-06-19 Thread Obi

Hi all,

I'm sorry if this is a FAQ, but I couldn't find it ... I have problem with  
the talk command. From my Debian 1.3 laptop, there is no way to talk to 
somebody else. I tried on a SunOS, on another Linux box (slackware) but with 
no luck: the talk sits with a Checking for invitation on a caller's machine.

If from the SunOS/Slackware box I do a talk to my machine, same problem, but 
if I do a ntalk I got the message on my Debian machine, but I cannot answer (I 
guess that ytalk/talk does not understand the ntalk protocol).

So what am I missing? What am I doing wrong?

You have a connection with dynamic IP, right?  In order to use talk in these 
circumstances, you need to change your hostname to one that corresponds to your
IP.  Something like line43.yourprovider.net.  The command for changing hostname 
is hostname, so to make it work, you have to type 
hostname line43.yourprovider.net
You can do this from your ip-up script to make sure you have talk always working

Both of them do understand ntalk protocol.  However, suns have their ntalk/talk
ports switched as opposed to linux.  Your /etc/services file should containt the
following lines:

talk517/udp
ntalk   518/udp

On suns, talk would be port 518 and ntalk is 517.  The solution is to fix this 
problem on one of the ends.

Actually I have always a static IP it's only change if I'm at home or at 
school. And the name change when is at school or at home. And I had this 
problem at school (I didn't try yet at home) where my hostname is the 
correct one ...

I'll check it out. And what about the Slackware box? It's linux anyway ...
