talk, ntalk server problem?


The end objective is a working private (no public servers, thank you) command line (non-gui) chat program between self and grandson. 'write' is a bit too primitive. That seems to leave 'talk', 'ntalk', 'ytalk' etc.

If there is another command line private server chat program, I'll be happy to try that instead. But for present, have problem getting talk/ntalk/ytalk to work.

I run Fedora; grandson runs Ubuntu. I want first to get talk working between a fedora 10 and fedora 12 box here. Then I will worry about the remote Ubuntu, with which I am less familiar.

The clients seems to start properly on the calling machine, but there is no activity/response at/from the target machine. I have tried explicitly naming the host and terminal in the call, and even using a full black-screen (Ctrl+Alt+F2) login to avoid any Xwindow problems.

Suspect there should be server or daemon on the receiving end, but have not found any guidance on how that works.

I have found /etc/xinetd.d/ntalk and ..talk;
edited with vi to make 'disable = no'
then /etc/initd/xinetd restart
..still no joy.

any clues?

you'll need to open the firewall for that relevant port:

Code:
grep talk /etc/services

talk            517/udp
ntalk           518/udp
.
.
.
I suspect they are plaintext (not encrypted). For an encrypted connection you could login to his system using ssh then use a local tool or one of the above via 127.0.0.1 ie l0 interface.
