<p><font size="2">2.永久保留.</font></p>
<p><font size="2"><span style="font-size: 13px">打开/etc/rc.conf<br />
加入或修改：ifconfig_网卡名称=&quot;inet x.x.x.x&nbsp;&nbsp;netmask x.x.x.x&quot;</span>
                        <br />
之后 reboot 或 #<span style="font-size: 13px">sh /etc/rc</span></font></p>

这种<a target="_blank" href="#" class="UBBWordLink">方法</a>，信息永久保留，但是修改完需要重启机器。</p>
<p>如果要<a target="_blank" href="#" class="UBBWordLink">设置</a>多IP地址可用别名方式作修改如下</p>
<p>ifconfig_lnc0=&quot;inet 10.0.0.199&nbsp; netmask 255.255.255.0&quot;<br />
改为</p>
<p>ifconfig_lnc0_alias0=&quot;inet 10.0.0.198&nbsp; netmask 255.255.255.0&quot;<br />
ifconfig_lnc0_alias1=&quot;inet 10.0.0.197&nbsp; netmask 255.255.255.0&quot;<br />
