期望脚本ssh返回无效的命令名称

我正在尝试编写一个期望脚本,它将ssh到服务器,发送sudo su,然后检查iptables状态并将输出放在服务器上的日志文件中.下面是脚本.

1 #!/usr/bin/expect
  2 exp_internal 1
  3 log_user 0
  4 set timeout 10
  5 set password  "******"
  6 
  7 spawn /usr/bin/ssh -l subhasish *.*.*.* -p 10022
  8 
  9 expect {
 10      -re "password: " {send "$password\r"}
 11      -re "$ "  {send "sudo su\r"}
 12      -re "[sudo] password for subhasish:" {send "$password\r"}
 13      -re "# "  {send "service iptables status\r"}
 14        }
 15 set output $expect_out(buffer)
 16 send "exit\r"
 17 puts "$output\r\n" >> output.log
