WinPopup

Bruce Garlock came across this script and asked the authors for permission to republish it here:

Hm, how old this ditty is? I did not really touch Samba for a very loooong while. Does it still works with current versions? I even do not really remember how this script looks although I can roughly imagine.:-) I thought that at least in some moment this was included with some other third-party examples in Samba sources. I may mix that with some other two- or three-liner.

If you think that this is still useful then, sure, go ahead and publish it. It is already somewhere on the net. I hope that it is not too grotty. Likely faster to throw in something like that when you need it instead of trying to find it somewhere.

Bruce notes: FYI: I have tested this on SAMBA 2.2.7, RH AS 2.1

This is a perl script that sends out a SMB Message to all users via "WinPopUp", using SAMBA. I thought it would be a nice addition for the code section of the website. The authors and credits are part of the perl script.

#@(#) A perl script which allows you to announce whatever you choose to
#@(#) every PC client currently connected to a Samba Server...
#@(#) ...using "smbclient -M" message to winpopup service.
#@(#) Default usage is to message every connected PC.
#@(#) Alternate usage is to message every pc on the argument list.
