Linux-expect Automated Telnet scripts

Simple mode:

#!/usr/bin/expect-FSetTimeout5spawn ssh [email protected]192.168.0.1expect"*assword*"Send"root\r"expect"#"Send"ifconfig \ r"expect EOF

Explain:

send：用于向进程发送字符串expect：从进程接收字符串 比如：expect "*assword*"
spawn：启动新的进程interact：允许用户交互

How to use variables:

#!/usr/bin/expect-FSetPort ASetUser RootSetHost192.168.0.12SetPassword RootSetTimeout-1Spawn ssh-D $port [email protected] $host"ifconfig"Expect {"*yes/no"{Send"yes\r"; Exp_continue}"*assword:"{Send"$password \ r"}} expect"*#*"Send"ifconfig >/home/cfg \ r"Send"exit\r"}

Explain:

Expect {  "*yes/no" {send "yes\r"; exp_continue}  "*assword:" {send "$password \ r "  }  } 
Select mode, exp_continue means continue.

To get a variable by reading a configuration file:
Configuration file

192.168. 0.1 Root 192.168. 0.2 Root

Automated logon scripts

#!/usr/bin/expect-FSetf [Open./IP R] while{[Gets $f line]>=0 } {       SetIP [lindex $line0]     SetPWD [Lindex $line1]spawn ssh $ipexpect"*password:"{Send"$pwd \ r"}expect"#"Send"ifconfig \ r"Send"exit\r"Interact}

Explain:

Can be more than one server loop execution, is a very use of the way!

Automating Remote Copy files:

#!/usr/bin/expect-FSetPort ASetUser RootSetHost192.168.28.30SetPassword RootSetTimeout-1Spawn SCP $host:/home/cfg./Expect {"*yes/no"{Send"yes\r"; Exp_continue}"*assword:"{Send"$password \ r"}}expect EOF

Explain:

The same principle as SSH

Write the file after the command is executed remotely, and then through the SCP to the native server:

#!/usr/bin/expect-FSetPort ASetUser RootSetHost192.168.28.30SetPassword RootSetTimeout-1Spawn ssh-D $port [email protected] $host"ifconfig"Expect {"*yes/no"{Send"yes\r"; Exp_continue}"*assword:"{Send"$password \ r"}}expect"*#*"Send"ifconfig >/home/cfg \ r"Send"exit\r"interactspawn SCP $host:/home/cfg./Expect {"*yes/no"{Send"yes\r"; Exp_continue}"*assword:"{Send"$password \ r"}}expect EOF

Explain:

Automation operations, remote interaction from Server a SSH to Server B, and then execute the commands on Server B.
