wall - write to all users
Wall reads its standard input until an end-of-file. It then sends this message, preceded by `Broadcast Message ...', to all logged in
The sender should be super-user to override any protections the users may have invoked.

`Cannot send to ...' when the open on a user's tty file fails.

wall -- send a message to everybody's terminal.
wall [-n] [ message ]
Wall sends a message to everybody logged in with their mesg(1) permission set to yes. The message can be given as an argument to wall, or
it can be sent to wall's standard input. When using the standard input from a terminal, the message should be terminated with the EOF key
The length of the message is limited to 20 lines. For every invocation of wall a notification will be written to syslog, with facility
LOG_USER and level LOG_INFO.
OPTIONS -n Suppresses the normal banner printed by wall, changing it to "Remote broadcast message". This option is only available for root if
wall is installed set-group-id, and is used by rpc.walld(8).
Wall ignores the TZ variable - the time printed in the banner is based on the system's local time.
SEE ALSO mesg(1), rpc.rwalld(8).

Say I'm running a FreeBSD webserver (w/apache). I've managed to close ALL open ports (including SSH/telnet and portmapper), excepting '80' that apache is listening on. A netstat -a shows me nothing open.
