　　R1#tclsh
　　R1(tcl)#foreach address { ip_address1 ip_address2 ip-address3 } { ping $address re 5 si 1500 }
　　R1(tcl)#tclquit
　　For login one router, then from there to ping other devices. We can view result from web

　　yum -y install expect
　　please refer http://hj192837.blog.51cto.com/655995/1352783 to send mail via outside ISP
　　vi /tmp/telnet.sh
　　#!/usr/bin/expect -f
　　#telnet auto login
　　set timeout -1
　　set host 192.168.1.20
　　set user cisco
　　set password cisco
　　spawn telnet $host
　　expect "*name:"
　　send "$user\r"
　　expect "*word:"
　　send "$password\r"
　　foreach address { 192.168.1.21 192.168.1.22 } {
　　expect "*#"
　　send "ping $address\r"
　　}
　　expect "*#"
　　send "exit\n"
　　#sleep is apply on above send command
　　sleep 2
　　expect eof
　　vi /tmp/pingtest.sh
　　ping -c 5 192.168.1.20 &> /dev/null
　　result=$?
　　if [ $result -eq 0 ]
　　then
　　/tmp/telnet.sh > /tmp/telnet-pingtest.txt
　　echo "ping test result" | mail -s "ping test result" -a /tmp/telnet-pingtest.txt 133xxxxxxxx@189.cn
　　else
　　echo "can not reach R1" | mail -s "can not reach R1" 133xxxxxxxx@189.cn
　　fi
　　chmod +x /tmp/telnet.sh /tmp/pingtest.sh
　　首先完成ssh cisco@192.168.1.20
　　vi /tmp/ssh.sh
　　#!/usr/bin/expect -f
　　#ssh auto login
　　set timeout -1
　　set host 192.168.1.20
　　set user cisco
　　set password cisco
　　spawn ssh $host -l $user
　　expect "*password:"
　　send "$password\r"
　　foreach address { 192.168.1.21 192.168.1.22 } {
　　expect "*#"
　　send "ping $address\r"
　　}
　　expect "*#"
　　send "exit\n"
　　#sleep is apply on above send command
　　sleep 2
　　expect eof
　　vi /tmp/pingtest.sh
　　ping -c 5 192.168.1.20 &> /dev/null
　　result=$?
　　if [ $result -eq 0 ]
　　then
　　/tmp/ssh.sh > /tmp/ssh-pingtest.txt
　　echo "ping test result" | mail -s "ping test result" -a /tmp/ssh-pingtest.txt 133xxxxxxxx@189.cn
　　else
　　echo "can not reach R1" | mail -s "can not reach R1" 133xxxxxxxx@189.cn
　　fi
　　chmod +x /tmp/ssh.sh /tmp/pingtest.sh
　　You can add to crontab to send your mail periodically.
