Can also be done with Samba. I wrote this privately, but seeing
how many people believe it's not possible to send from a NT/95
PC to a FreeBSD box, here's the extract from smb.conf(5) :
message command
This specifies what command to run when the server
receives a WinPopup style message.
This would normally be a command that would deliver the
message somehow. How this is to be done is up to your
imagination.
What I use is:
message command = csh -c 'xedit %s;rm %s' &
This delivers the message using xedit, then removes it
afterwards. NOTE THAT IT IS VERY IMPORTANT THAT THIS COM-
MAND RETURN IMMEDIATELY. That's why I have the & on the
end. If it doesn't return immediately then your PCs may
freeze when sending messages (they should recover after
30secs, hopefully).
All messages are delivered as the global guest user. The
command takes the standard substitutions, although %u
won't work (%U may be better in this case).
Apart from the standard substitutions, some additional
ones apply. In particular:
%s = the filename containing the message
%t = the destination that the message was sent to (proba-
bly the server name)
%f = who the message is from
You could make this command send mail, or whatever else
takes your fancy. Please let me know of any really inter-
esting ideas you have.
Here's a way of sending the messages as mail to root:
message command = /bin/mail -s 'message from %f on %m'
root < %s; rm %s
If you don't have a message command then the message won't
be delivered and Samba will tell the sender there was an
error. Unfortunately WfWg totally ignores the error code
and carries on regardless, saying that the message was
delivered.
If you want to silently delete it then try "message com-
mand = rm %s".
For the really adventurous, try something like this:
message command = csh -c 'csh < %s |&
/usr/local/samba/bin/smbclient \
-M %m; rm %s' &
this would execute the command as a script on the server,
then give them the result in a WinPopup message. Note that
this could cause a loop if you send a message from the
server using smbclient! You better wrap the above in a
script that checks for this :-)
Default: no message command
Example:
message command = csh -c 'xedit %s;rm %s' &
