linux配置动态dns_自带动态域名解析的路由

step 1 安装lynx

         yum -y install lynx

step 2 修改/etc/sysconfig/network-scripts/ifup-ppp

        vi /etc/sysconfig/network-scripts/ifup-ppp

找到:

# check that xDSL connection

if [ “$TYPE” = “xDSL” ] ; then

    if [ -x /sbin/adsl-start -o -x /usr/sbin/adsl-start ] ; then

        adsl-start /etc/sysconfig/network-scripts/$CONFIG

        exit $?

    else

        /usr/bin/logger -p daemon.info -t ifup-ppp /

            $”adsl-start does not exist or is not executable for ${DEVICE}”

        exit 1

按i进入编辑模式，将内容改为：

# check that xDSL connection

if [ “$TYPE” = “xDSL” ] ; then

    if [ -x /sbin/adsl-start -o -x /usr/sbin/adsl-start ] ; then

        adsl-start /etc/sysconfig/network-scripts/$CONFIG

        /usr/bin/lynx -mime_header -auth=username:password “http://www.3322.org/dyndns/update?system=dyndns&hostname=mydns.3322.org”

        exit $?

    else

        /usr/bin/logger -p daemon.info -t ifup-ppp /

            $”adsl-start does not exist or is not executable for ${DEVICE}”

        exit 1

按Esc，:wq保存退出

*注：/usr/bin/lynx -mime_header -auth=username:password “http://www.3322.org/dyndns/update?system=dyndns& hostname=mydns.3322.org”中“username”为您在3322.org的用户名，”password”为密码，mydns为你 的动态域名
