	If your 'talk' works when you specify the terminal i.e.
'talk uid ttyxx', then the following bug fix should work for you.

	In the file get_names.c it sets his_tty to (char *)0
if you don't give a tty number. Later it copies TTY_SIZE chars
from there into the request structure. On our system it copies
garbage. The following diff gives the simple fix:

diff get_names.c get_names.c.bad
101,105c101,102
<     if (his_tty) {
< 	    strncpy(msg.r_tty, his_tty, TTY_SIZE);
< 	    msg.r_tty[TTY_SIZE - 1] = '\0';
<     } else
< 	    msg.r_tty[0] = '\0';

>     strncpy(msg.r_tty, his_tty, TTY_SIZE);
>     msg.r_tty[TTY_SIZE - 1] = '\0';
