出现问题：
[root@arslinux-01 expect]# ./3.expect root 192.168.194.132 "ls;w;vmstat 1"
spawn ssh [email protected]
[email protected]'s password: yum
Permission denied, please try again.
现象：
[root@arslinux-01 expect]# vim 3.expect
#!/usr/bin/expect
set user [lindex $argv 0]
set host [lindex $argv 1]
set passwd "123456"
set cm [lindex $argv 2]
spawn ssh $user@$host
expect {
"yes/no" { send "yes\r"}
"password:" { send "$passwd\r" }
}
expect "]*"
send "$cm\r"
expect "]*"
send "exit\r"
[root@arslinux-01 expect]# chmod a+x 3.expect
[root@arslinux-01 expect]# ./3.expect root 192.168.194.132 "ls;w;vmstat 1"
spawn ssh [email protected]
[email protected]'s password:
Permission denied, please try again.
解决方法：
在 expect 执行的这台机器上
vim /etc/ssh/sshd_config
找到 PermitRootLogin 取消注释，并改为 yes
PermitRootLogin yes
重启 sshd
问题应该可以解决
