pon 是什么命令？

wiinngg

在redhat 9下有没有pon命令？

memory

pon只是一个ppp的脚本主要内容其实就一行：
exec /usr/sbin/pppd call $PROVIDER "$@"

这个脚本应该是debian linux发行版中特有的，是由debian的ppp维护人员编写的。

下面是pon全部内容：
#!/bin/sh

while [ $# -ge 1 ]; do
case "$1" in
  --quick|-q)
    QUICK=true
    shift
    ;;
  -*)
    echo "\
Usage: pon [OPTIONS] [provider] [arguments]
  -q|--quick           pppd hangs up after all ip-up scripts are run

If pon is invoked without arguments, /etc/ppp/ppp_on_boot file will be
run, presuming it exists and is executable. Otherwise, a PPP connection
will be started using settings from /etc/ppp/peers/provider.
If you specify one argument, a PPP connection will be started using
settings from the appropriate file in the /etc/ppp/peers/ directory, and
any additional arguments supplied will be passed as extra arguments to
pppd.
"
    exit 0
    ;;
  *)
    break
    ;;
esac
done

if [ ! -r /etc/ppp/peers/ ]; then
  echo "Error: only members of the 'dip' group can use this command."
  exit 1
fi

if [ "$1" ]; then
  PROVIDER=$1
  shift
fi

if [ -z "$PROVIDER" ]; then
  if [ -x /etc/ppp/ppp_on_boot ]; then
    [ "$QUICK" ] && touch /var/run/ppp-quick
    exec /etc/ppp/ppp_on_boot
  fi
  # try the default script
  PROVIDER=provider
fi

if [ ! -e "/etc/ppp/peers/$PROVIDER" ]; then
  echo "\
The file /etc/ppp/peers/$PROVIDER does not exist. Please create it or use
a command line argument to use another file in the /etc/ppp/peers/ directory."
  exit 1
fi

[ "$QUICK" ] && touch /var/run/ppp-quick
exec /usr/sbin/pppd call $PROVIDER "$@"

与pon对应的脚本是poff。pon用你的拨号配置拨号上网；poff则相反，用于挂断ppp连接。

Arch Linux 中也有，可能就是用的 Debian 的吧

wiinngg

redhat 中有没有类似的命令可以拨号的，例如linux 做VPNclient的虚拟拨号。。

memory

自己写一段不就行了？！实在不行还可以照葫芦画瓢吗。

wiinngg

就是不会啊 郁闷。。。 救命啊。。。 麻烦大侠给出具体的方法。。。

wiinngg

成功了。。。 多谢大侠。。。。。。。 非常感谢。。
麻烦把poff的代码也贴下出来好吗。。。。。 嘻嘻。。。
