FreeBSD中talk无法使用的解决办法

提问：FreeBSD中talk无法使用的解决办法

#talk zz
出现
Checking for invitation on caller''s machine
并始终不变.

解决：
Make sure that the (n)talkd daemon is actually running on the recipient''s machine. To test talk/ntalkd on the machine you are calling from, edit /etc/inetd.conf and uncomment the line:

ntalk dgram udp wait nobody:tty /usr/libexec/ntalkd ntalkd

then do
/etc/rc.d/inetd restart
