[root@localhost 111]# ls  运行坏境为FC4. /expect 已经安装成功.
fw  netwatch.exp
[root@localhost 111]# ./fw
./fw: line 4: netwatch.exp: command not found
./fw: line 6: netwatch.exp: command not found
./fw: line 12: syntax error near unexpected token `do'
./fw: line 12: `       do some recovery action here ...'
[root@localhost 111]#

netwatch.exp脚本内容
#!/usr/bin/expect

set target [lindex $argv 0]
set timeout 1
spawn ping -c 1 -s 1 $target

expect {
    " 0% packet loss" {
        exit 0
    }
    timeout {
        exit 1
    }
}

fw脚本内容

#!/bin/sh

netwatch.exp 192.168.1.1
result1=$?
netwatch.exp 192.168.2.1
result2=$?
if [ "$result1" eq 0 ] && [ "$result2" eq 0 ] ; then

# 如果上次检测时连接丢失，而此次恢复正常
    if [ -e /var/run/lost-connection ] ; then
       do some recovery action here ...
       rm /var/run/lost-connection
    fi

# 如果网关1不可达
elif [ "$result1" ne 0 ] ; then
   change default route to 192.168.2.1
   do some action here, such as iptables NAT

   # 创建连接丢失标识
   touch /var/run/lost-connection

# 如果网关2不可达
elif [ "$result2" ne 0 ] ; then
   change default route to 192.168.1.1
   do some action here, such as iptables NAT

   # 创建连接丢失标识
   touch /var/run/lost-connection
fi

希望高人帮我看看了.

./netwatch.exp
或者把netwatch.exp所在目录加入路径

do那个错误不用讲了吧？

ycfei

你还是讲下吧..小弟不懂SHELL啊.
谢谢"他爹"了.

waker

去英文版问吧？或者找个软件翻译一下

ycfei

噢..谢谢.

再帮我看下了.
执行后又出错了.
spawn ping -c 1 -s 1 192.168.100.1
PING 192.168.100.1 (192.168.100.1) 1(29) bytes of data.

./fw: line 7: [: eq: binary operator expected
./fw: line 18: [: ne: binary operator expected

fw的脚本如下:
#!/bin/sh
/111/netwatch.exp 192.168.100.1
result1=$?
/111/netwatch.exp 192.168.10.1
result2=$?

if [ "$result1" eq 0 ] && [ "$result2" eq 0 ]
then

# ...................
    if [ -e /var/run/lost-connection ]
    then
       rm /var/run/lost-connection
    fi



elif [ "$result1" ne 0 ]
then
        /sbin/ip  route replace via 192.168.10.1 dev eth1
elif [ "$result2" ne 0 ]
then
        /sbin/ip  route replace via 192.168.100.1 dev eth1 talbe 100
else
        echo "yy"

-eq
-ne

看新手导航吧？省点时间

ycfei

大哥.你帮我改下啊.
我急用啊.

ycfei

int1 -eq int2　　　　两数相等为真
　　　　int1 -ne int2　　　　两数不等为真
　　　　int1 -gt int2　　　　int1大于int2为真
　　　　int1 -ge int2　　　　int1大于等于int2为真
　　　　int1 -lt int2　　　　int1小于int2为真
　　　　int1 -le int2　　　　int1小于等于int2为真

老大.谢谢你..我找到了.
