[root@centos7-9094 bin]# ERROR: Timeout
I have disabled the SELinux, the iptables, and even set the ssh-key to make it ssh or scp without password, but always got above error.
I have known the Expect may trapped into a long time silence without any reponse in some situation, does above error have some relation to that?
