Hi OpenSSH, I encountered that SSH will hang over after I input the password. Could you help show me how to resolve this problem? Thanks for your help. Please find the ssh debug info and my ssh version as below. $ ssh -vvv user1@remote_host OpenSSH_6.9p1, LibreSSL 2.1.8 debug1: Reading configuration data /Users/user1/.ssh/config debug1:
