From 9b6b01aab6a6a0ebb34798bb78febb2df17b302d Mon Sep 17 00:00:00 2001 From: Volker Lendecke Date: Mon, 21 Dec 2009 21:50:43 +0100 Subject: s3:winbind: Add a lower-cost alternative to wbinfo -t: wbinfo --ping-dc This just does a NULL RPC call through an existing NETLOGON connection. If someone knows an operation that "just works" and does not return NOT_SUPPORTED, please tell me :-) --- source3/winbindd/winbindd_ping_dc.c | 96 +++++++++++++++++++++++++++++++++++++ 1 file changed, 96 insertions(+) create mode 100644 source3/winbindd/winbindd_ping_dc.c (limited to 'source3/winbindd/winbindd_ping_dc.c') diff --git a/source3/winbindd/winbindd_ping_dc.c b/source3/winbindd/winbindd_ping_dc.c new file mode 100644 index 0000000000..e06e5896c2 --- /dev/null +++ b/source3/winbindd/winbindd_ping_dc.c @@ -0,0 +1,96 @@ +/* + Unix SMB/CIFS implementation. + async implementation of WINBINDD_PING_DC + Copyright (C) Volker Lendecke 2009 + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
