Where can I find...

[Daniel Rudy]

....the protocol specification for the Windows Messenger (not Msgs, MsnMsgs,
or other IM clients) service? I'm looking on msdn, and I found the APIs for
the messenger service, but that's not exactly what I need. Reason for this
is that I'm writing a unix tool to send administrative popup messages to
Windows clients over a network. Messages such as firewall alerts to a
security administrator. Because the machine sending the alerts is a bastion
host, I would rather not have to install Samba to get this functionality.
Anything that any of you can recommend is appriciated.

Please maintain crosspost. Thank you.

The protocol almost certainly isn't published, as with most of those
sorts of things -- but assuming that Samba has funcionality equivalent
to 'net send', you could just grab the source and use that as
documentation. That's what did when I needed to do some NTLM stuff a
while ago, it's not a lot harder than starting with a description of the
byte stream. A quick google for samba "net send" looks fairly hopeful.

Also, you do realise that people might have the windows messenger
service turned off because of messenger spam? I guess if they're on a
LAN you probably have more control over that sort of thing.
