Getting NOTIFIED when someone logs in
To receive a windowgram when one of your friends logs in, he must be
announcing his login and you must be able to receive it. All you have to
do is create a file in your home directory and name it '.anyone'. In
this file include a list, 1 per line, of usernames of people from whom
you want to receive login notification.
Then to receive these notifications, run the program 'znol'. This program will
read your .anyone file and subscribe you to the appropriate messages.
The tricky part is that the people you are interested in must set their
exposure such that they allow notifications to be sent when they log in
or out. This is not set by default. To do so, the person must type:
zctl set exposure realm-announced
or
zctl set exposure net-announced
or
zctl set exposure net-visible
(Note: net-announced and net-visible are currently the same. They will apply
when sites outside of Project Athena adopt Zephyr)
The difference between these two is that to receive notification from someone
with realm-announced, you must pass authentication with Kerberos whereas
net-announced performs no check for authentication.
See the man pages on znol and zctl for more info.
