The following devices i have and connect to the same route: 1. normal pc 2. macbook air 3. ipad I installed openSSH on my ipad as the SSH server. I can use my normal pc (putty) to connect ipad by ssh. But when I was trying to use mac (Terminal) as the client to connect the ipad by ssh, it shows some error: connect timed out. I am sure the ip i use is correct. Do anyone knows any reason will cause these kind of issue? Thanks.
