 动态域名ppp.linkup配置问题
家里的机器，adsl上网，动态IP，在http://www.2mydns.com/申请了个二级域名，更新DDNS方法是http://dyn.2mydns.com/dyn.asp?username=bla&password=bla&hostname=bla.2mydns.com&myip=123.321.0.1
写了个脚本ddns.sh
#!/bin/sh
IP=`ifconfig tun0 | grep inet | awk '{print $2}'`;
/usr/local/bin/wget -q "http://dyn.2mydns.com/dyn.asp?username=bla&password=bla&hostname=bla.2mydns.com&myip=$IP" -O /dev/null;
执行后，http://bla.2mydns.com/正确指向家中IP，现在想在每次ppp建立连接后自动更新动态dns记录，于是在/etc/ppp/下建立ppp.linkup文件
adsl:
!bg /home/bla/ddns.sh > /dev/null
但每次ppp连接建立后都会报告错误：
tun0: Warning: /etc/ppp/ppp.linkup: !bg /home/bla/ddns.sh > /dev/null: Invalid command
搞不懂怎么就无效命令了，请指点迷津，谢谢

格式问题?
贴一下ppp.conf,ppp.linkup |

# Example of ppp.linkup file
#
# This file is checked when ppp establishes a connection.
# ppp searches the labels in this file as follows:
#
# 1) The label that matches the IP number assigned to our side.
#
# 2) The label specified on the command line to ppp.
#
# 3) If no label has been found, use MYADDR if it exists.

# It is no longer necessary to re-add the default route here as our
# ppp.conf route is `sticky' (see the man page).
# If you're into sound effects when the link comes up, you can run
# ``auplay'' (assuming NAS is installed and configured).

前面空一格或tab试试. |

加了个空格，顺利通过，更新DNS成功，太神了点吧？！ |
