From 1c6ed9f3379faac83da0ed3e95cbd49003ac0dd1 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Tue, 26 May 2009 13:03:27 +0200 Subject: User networking: Show active connections In case you're wondering what connections exactly you have open or maybe redir'ed in the past, you can't really find out from qemu right now. This patch enables you to see all current connections the host only networking holds open, so you can kill them using the previous patch.
