Telnet Connections and broadcast messages

CatSC · 11-06-2003, 08:21 AM

Hello everyone!
For example I'm running Telnet and I have couple
of people connected. How do I disconnect a selected user?
Also how can I as root send a broadcast message to all connected users?

Disconnecting selected users I dont know,
but sending a message to all those conncted is easy:

wall your_message

( wall usually at /usr/bin/wall )

yep wall is pretty cool....as for users just kill the telnetd process for users you don't want on the box. ps ux will show you what process is owned by who.
