To send popups to lan user PC's from linux router
 

hi
i have lan and at the end of every month we have to pick money form all users, is there any way to do so that i could send special pop up from mi linux router to theyr pc's with information "You should bring money and etc.." i heard one admin did so.

smb client
 

if the linux router has the smb client then you can have a script along the lines of

<shell script>
#!/bin/sh
#filename netsend

echo $2 | smbclient -M $1

#example: ./netsend MACHINE don't forget your money
</shell script>


You should easily be able alter this to send to everyone you want it to. :)
