From 632217f1e4a362f0b9a1ab6dd0b2e730de9f5b7e Mon Sep 17 00:00:00 2001 From: aliguori Date: Wed, 10 Dec 2008 15:14:13 +0000 Subject: [PATCH] Accept password as an argument to 'change vnc password' monitor command (Chris Webb) This allows easier use of the change vnc password monitor command from management scripts, without having to implement expect(1)-like behaviour.
