2 <term><anchor id="MESSAGECOMMAND"/>message command (G)</term>
3 <listitem><para>This specifies what command to run when the
4 server receives a WinPopup style message.</para>
6 <para>This would normally be a command that would
7 deliver the message somehow. How this is to be done is
8 up to your imagination.</para>
10 <para>An example is:</para>
12 <para><command moreinfo="none">message command = csh -c 'xedit %s;rm %s' &</command>
15 <para>This delivers the message using <command moreinfo="none">xedit</command>, then
16 removes it afterwards. <emphasis>NOTE THAT IT IS VERY IMPORTANT
17 THAT THIS COMMAND RETURN IMMEDIATELY</emphasis>. That's why I
18 have the '&' on the end. If it doesn't return immediately then
19 your PCs may freeze when sending messages (they should recover
20 after 30 seconds, hopefully).</para>
22 <para>All messages are delivered as the global guest user.
23 The command takes the standard substitutions, although <parameter moreinfo="none">
24 %u</parameter> won't work (<parameter moreinfo="none">%U</parameter> may be better
27 <para>Apart from the standard substitutions, some additional
28 ones apply. In particular:</para>
31 <listitem><para><parameter moreinfo="none">%s</parameter> = the filename containing
32 the message.</para></listitem>
34 <listitem><para><parameter moreinfo="none">%t</parameter> = the destination that
35 the message was sent to (probably the server name).</para></listitem>
37 <listitem><para><parameter moreinfo="none">%f</parameter> = who the message
38 is from.</para></listitem>
41 <para>You could make this command send mail, or whatever else
42 takes your fancy. Please let us know of any really interesting
43 ideas you have.</para>
46 <para>Here's a way of sending the messages as mail to root:</para>
48 <para><command moreinfo="none">message command = /bin/mail -s 'message from %f on
49 %m' root < %s; rm %s</command></para>
51 <para>If you don't have a message command then the message
52 won't be delivered and Samba will tell the sender there was
53 an error. Unfortunately WfWg totally ignores the error code
54 and carries on regardless, saying that the message was delivered.
57 <para>If you want to silently delete it then try:</para>
59 <para><command moreinfo="none">message command = rm %s</command></para>
61 <para>Default: <emphasis>no message command</emphasis></para>
62 <para>Example: <command moreinfo="none">message command = csh -c 'xedit %s;
63 rm %s' &</command></para>
