From ee8c45689526ca973407cbb77bce7b96a062c40b Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Tue, 12 Aug 2014 01:41:42 +0200 Subject: networkd: add minimal client tool "networkd" to query network status In the long run this should become a full fledged client to networkd (but not before networkd learns bus support). For now, just pull interesting data out of networkd, udev, and rtnl and present it to the user, in a simple but useful output. --- src/shared/arphrd-list.c | 59 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 59 insertions(+) create mode 100644 src/shared/arphrd-list.c (limited to 'src/shared/arphrd-list.c') diff --git a/src/shared/arphrd-list.c b/src/shared/arphrd-list.c new file mode 100644 index 0000000000..6e113eff7a --- /dev/null +++ b/src/shared/arphrd-list.c @@ -0,0 +1,59 @@ +/*-*- Mode: C; c-basic-offset: 8; indent-tabs-mode: nil -*-*/ + +/*** + This file is part of systemd. + + Copyright 2014 Lennart Poettering + + systemd is free software; you can redistribute it and/or modify it + under the terms of the GNU Lesser General Public License as published by + the Free Software Foundation; either version 2.1 of the License, or + (at your option) any later version. + + systemd 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.
