From 9fb77da4515a788a2de063801fcbfbe99d7475ec Mon Sep 17 00:00:00 2001 From: nbd Date: Thu, 7 Aug 2008 15:28:48 +0000 Subject: add basic interface alias support. for now (since we don't use ip in our network scripts yet), it adds :1, :2, ... alias interfaces this will change when we add support for the ip utility, but the config format will remain the same. example: config alias test option interface lan option ipaddr 192.168.1.1 option netmask 255.255.0.0 git-svn-id: svn://svn.openwrt.org/openwrt/trunk@12241 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- package/base-files/files/lib/network/config.sh | 117 +++++++++++++++++-------- 1 file changed, 80 insertions(+), 37 deletions(-) (limited to 'package/base-files/files/lib/network') diff --git a/package/base-files/files/lib/network/config.sh b/package/base-files/files/lib/network/config.sh index 0a7464495f..13e1980d9c 100755 --- a/package/base-files/files/lib/network/config.sh +++ b/package/base-files/files/lib/network/config.sh @@ -142,6 +142,66 @@ set_interface_ifname() { uci_set_state network "$config" device "$device" } +setup_interface_static() { + local iface="$1" + local config="$2" + + config_get ipaddr "$config" ipaddr + config_get netmask "$config" netmask + config_get ip6addr "$config" ip6addr + [ -z "$ipaddr" -o -z "$netmask" ] && [ -z "$ip6addr" ] && return 1 + + config_get gateway "$config" gateway + config_get ip6gw "$config" ip6gw + config_get dns "$config" dns + config_get bcast "$config" broadcast + + [ -z "$ipaddr" ] || $DEBUG ifconfig "$iface" "$ipaddr" netmask "$netmask" broadcast "${bcast:-+}" + [ -z "$ip6addr" ] || $DEBUG ifconfig "$iface" add "$ip6addr" + [ -z "$gateway" ] || $DEBUG route add default gw "$gateway" dev "$iface" + [ -z "$ip6gw" ] || $DEBUG route -A inet6 add default gw "$ip6gw" dev "$iface" + [ -z "$dns" ] || { + for ns in $dns;
