Porting OpenWrt-nvram to Mac OS X

 

甚麼是NVRAM?

NVRAM 全名是 Non-Volatile Ram ，在 OpenWrt 裡是用了 Flash Rom 最後的 64K 區塊，用來儲存一些環境參數，OpenWrt 通過這些參數來設定網路，DHCP，DNS和記載硬體版本等。

常用的 nvram 指令有以下 4 種：

1. nvram show：列出 NVRAM 內所有參數，我們亦可以用 grep 命令來抽取部份資訊，

例如下列命令列出了所 有用關鍵字' lan_' 開頭的參數，結果如下：

$ nvram show | grep lan_
vlan_port_vid_0=
vlan_port_vid_1=
vlan_src_type_0=ip
vlan_port_vid_2=
vlan_src_type_1=ip
vlan_port_vid_3=
vlan_src_type_2=ip
vlan_src_type_3=ip
vlan_src_type_4=ip
vlan_src_type_5=ip
vlan_src_type_6=ip
vlan_src_type_7=ip
vlan_src_type_8=ip
vlan_src_type_9=ip
vlan_wan_port_prio=
vlan_protocol_srcip_0=
vlan_protocol_srcip_1=
vlan_protocol_srcip_2=
vlan_protocol_srcip_3=
vlan_protocol_srcip_4=
vlan_protocol_srcip_5=
vlan_protocol_srcip_6=
vlan_protocol_srcip_7=
vlan_protocol_srcip_8=
vlan_wan_port_vid=
vlan_protocol_srcip_9=
lan_proto=dhcp
vlan_protocol_prio_0=
vlan_protocol_prio_1=
vlan_protocolbase_Enabled=0
vlan_protocol_prio_2=
vlan_protocol_prio_3=
vlan_protocol_prio_4=
vlan_protocol_prio_5=
vlan_protocol_prio_6=
vlan_protocol_prio_7=
vlan_protocol_prio_8=
vlan_protocol_vid_0=
vlan_protocol_prio_9=
vlan_protocol_vid_1=
vlan_protocol_vid_2=
vlan_protocol_vid_3=
vlan_protocol_vid_4=
vlan_protocol_vid_5=
vlan_protocol_vid_6=
vlan_protocol_vid_7=
vlan_protocol_vid_8=
vlan_protocol_vid_9=
lan_ifname=eth1
dhcp_vlan_id0=
dhcp_vlan_id1=
default_lan_netmask_br=255.255.255.0
default_lan_ipaddr_br=192.168.1.1
dhcp_vlan_id2=
lan_netmask=255.255.255.0
lan_ipaddr=192.168.1.1
dhcp_vlan_id3=
lan_hwaddr=00:11:22:33:44:55
vlan_port_prio_0=
vlan_port_prio_1=
vlan_portbase_Enabled=0
vlan_port_prio_2=
vlan_port_prio_3=

 

2. nvram set 參數=數值：用來新增或修改一些參數，例如我想把 LAN 的 IP 改為 192.168.1.168，可執行此命令。

$ nvram set lan_ipaddr=192.168.1.2
$ nvram commit

第 1 行是修改 IP 地址，第 2 行使變更後的結果，儲存到nvram記憶體區塊或檔案裡。

 

3. nvram unset 參數：用來刪除參數。

例如刪除 “vlan_wan_port_prio” 這個參數，請執行：

$ nvram unset vlan_wan_port_prio

 

4. nvram commit 參數：當你對 NVRAM 做了一大堆修改後，你需要把這些修改儲存起來，否則路由器或閘道器 reboot 後，這些修改便會消失。

$ nvram commit

 

由於 Mac OS X 本身就有 'nvram' 這個命令，為避免混淆，在編譯產生執行檔前，會自動判斷更名為 'xnvram'。
